A multi-day severe weather threat will strike the central U.S., with a couple of areas of focus and trigger for storms. Isolated severe storms overnight are possible before more widespread severe storms with significant severe weather potential move in Friday. <h2>Overnight</h2>Isolated severe storms are possible overnight on the north side of the low-pressure system through northern Nebraska, Siouxland, and SW Minnesota. A few severe storms Thursday evening produced ping pong ball size hail in Nebraska, and an isolated storm or two could persist through the overnight hours as well. However as the storms run into much colder air toward I-90 they will transition into sleet and freezing rain.<img src="https://media.weathernationtv.com/app/uploads/2023/03/1-1680204670106.jpg"><img src="https://media.weathernationtv.com/app/uploads/2023/03/3-30 RNC fri 12 am-1680231244548.JPG"><h2>Friday</h2>On Friday the threat becomes much more widespread through the Midwest and Great Lakes. We have a MODERATE risk (level 4 out of 5) of severe weather through Iowa and western Illinois, and a separate Moderate Risk through eastern Arkansas, the bootheel of Missouri, and west Tennessee. Please have multiple ways to get alerts throughout the day on Friday as we expect widespread, strong storms with large hail and damaging winds possible.<img src="https://media.weathernationtv.com/app/uploads/2023/03/enhanced risk-1680174974283.jpg">The tornado threat is most elevated across eastern Iowa and northwest Illinois, where low level rotation near the surface is strongest. This is also where stronger, longer track tornadoes are possible during the afternoon and evening.<img src="https://media.weathernationtv.com/app/uploads/2023/03/2-1680204524408.jpg">Wind gusts could top 60-70 mph in the red and pink highlighted areas as well. Straight line wind can do just as much damage as a low-end tornado. Please take all weather warnings seriously and remove any outdoor items that could blow away or become damaged by severe storms.<h2><img src="https://media.weathernationtv.com/app/uploads/2023/03/wind potential-1680175936529.jpg"></h2><h2>SIGNIFICANT THREATS</h2>There is a significant tornado risk (in red below) for parts of Iowa, Illinois and Missouri. This means that the environment here is conducive for strong, longer track tornadoes. There is a significant risk for strong winds too (in blue). Wind gusts can reach over 75 mph, these are hurricane strength winds! Now is the time to have a plan in place in the event of severe weather, and make sure everyone in your household can get to your safe place quickly.<img src="https://media.weathernationtv.com/app/uploads/2023/03/sig tornado-1680176996834.jpg">Storms could be moving as fast as 60 miles per hour, so you may not get a lot of lead time when a warning is issued. This is why it's important to have a safety plan and know where to go in the event a warning is issued for your town.<img src="https://media.weathernationtv.com/app/uploads/2023/03/sigw wind-1680176523655.jpg">The approaching low-pressure system and cold front will generate showers and general thunderstorms through mid morning in the upper Mississippi River Valley. These move into the Midwest by lunchtime. With daytime heating, energy in the atmosphere will increase and storms will begin to develop early afternoon from Green Bay down to St. Louis. The early storms will have a better chance of producing tornadoes due to their individual nature, but all severe hazards will be possible with all storms at any point in time. As evening wears on, the severe threat will transition to primarily a gusty wind threat as the storms merge into a squall line with powerful winds. The line will continue to move east through cities like Detroit and Cincinnati in the overnight hours.<video src="https://media.weathernationtv.com/app/uploads/2023/03/forecast severe-1680176786524.mp4" controls="true" width="100%"></video>You can plan and prepare for severe weather before it strikes. The day before, stock up on any essentials and charge electronics. Review your severe weather safety plan with your family. That plan should include knowing where your safe place is during a severe storm, and how to get there.<img src="https://media.weathernationtv.com/app/uploads/2023/03/6-1680216109391.jpg">The day of the event, stay up-to-date with the latest weather watches and warnings.

Kara has always been passionate about weather and knew from an early age that she wanted to become a meteorologist. Living in different regions of the country and experiencing weather events ranging from ice storms to tornadoes drove her to pursue a bachelor's degree in meteorology from the University of Oklahoma. Throughout college, storm chasing became a regular event for Kara, where she saw first-hand the power of the atmosphere. Kara graduated cum laude from OU and decided to further her meteorology education with a Master's degree from Mississippi State University. The deadly April 27, 2011 tornado outbreak struck while Kara was studying at MSU; her first “Dixie Alley” tornado event and an up close glimpse into the destruction of the storms she so closely studied. Her broadcast career began in Elvis’ birthplace, Tupelo, Mississippi, where she earned her Certified Broadcast Meteorologist seal from the American Meteorological Society. Kara's career has included coverage of all types of severe weather including tornado events, flooding and tropical systems across multiple southern states. Recently she helped cover the 2020 Easter Sunday deadly tornado outbreak in southeast Mississippi. In her free time, you can find Kara outdoors exploring new areas with her mini poodle,Truffles. Kara is also an avid runner and frequently races in 5Ks, 10Ks and half marathons.

Confidence is increasing in the threat of severe thunderstorms Friday into an area hard hit by severe storms the last few days (ABOVE).In the upper levels, a strong upper low will dig into the southwest from California. This upper-level energy will overspread warm, humid air at the surface, transported on a southerly wind from the Gulf. All severe weather ingredients will be in place for thunderstorm development by the afternoon, and all hazards of severe weather will be possible: damaging winds, large hail, and tornadoes. Overnight, a few isolated severe storms capable of producing large hail are possible in Oklahoma. Thursday evening, very isolated storms produced quarter to ping pong ball size hail. <img src="https://media.weathernationtv.com/app/uploads/2023/03/3-30 RSC OVN-1680231923900.JPG">Confidence is higher in widespread severe storms Friday as the main upper-level energy and cold front swing through. The Storm Prediction Center has issued a Moderate Risk (red area, level 4 out of 5) Friday due to the confidence of significant severe storms. <img src="https://media.weathernationtv.com/app/uploads/2023/03/1-1680205194798.jpg">Damaging winds and tornadoes will be the primary concerns as the front moves through. Please remember to have a plan in place in case severe weather strikes, and during the event of a tornado move to a basement or interior room away from windows.<img src="https://media.weathernationtv.com/app/uploads/2023/03/2-1680205239074.jpg"><img src="https://media.weathernationtv.com/app/uploads/2023/03/1-1680205264471.jpg">There is a significant risk for tornadoes and damaging winds across the mid-South. Some of the cities included in this are Memphis, Little Rock, Paducah, Jackson, Tupelo and Memphis. With a significant tornado threat there is a chance for strong, long track tornadoes with windspeeds higher than 110 mph. <img src="https://media.weathernationtv.com/app/uploads/2023/03/3-1680205304553.JPG">With a significant wind, gusts can reach hurricane strength at over 75 mph. Straight line winds of that strength can do damage similar to an EF-0 tornado. Bring any items inside that could get damaged from severe storms, or are at risk of being blown away!<img src="https://media.weathernationtv.com/app/uploads/2023/03/sig wind-1680178761375.jpg"><h1>TIMING</h1>Showers and storms continue early Friday morning, leftover from overnight. As the cold front swings through the Deep South Friday more storms will develop with a pocket through Arkansas, Mississippi, and Louisiana. The early storms that are individual supercells will have the highest chance to produce tornadoes. This will morph into a gusty wind threat as the individual supercells merge into a squall line with damaging winds through the late evening and overnight. Embedded tornadoes will still be possible with in the line of storms through the overnight hours. <video src="https://media.weathernationtv.com/app/uploads/2023/03/3-30 RSE stormz-1680232205782.mp4" controls="true" width="100%"></video>You can plan and prepare for severe weather before it strikes.

Significant Severe Weather Event for the South Friday

330RSCwideJPG-1680231807443.jpeg

The last day of March will feature an active pattern for the northern Plains, as yet another area of low pressure pushes out of the Rockies into Friday. The storm system is prompting another round of winter alerts INCLUDING BLIZZARD ALERTS for parts of South Dakota and Minnesota.<img src="https://media.weathernationtv.com/app/uploads/2023/03/3-1680215816593.jpg"> Snow will increase Friday as the low pressure system moves through. There will be a band of freezing rain changing over to snow through the Great Lakes, with mostly snow through the Dakotas. Eastern South Dakota will get ice as well, before snow moves in behind the initial band of ice.<video src="https://media.weathernationtv.com/app/uploads/2023/03/Futurecast Now-1680222297749.mp4" controls="true" width="100%"></video>Model agreement has been improving in terms of the location of heaviest snow. Portions of eastern North and South Dakota, along with the UP of Michigan, could get some of the highest snow totals. Models are indicating swaths of a foot of snow or more through these areas. Northern Wisconsin and the UP of Michigan will also have potential for higher snow accumulation impacts. Totals could eclipse over two feet in spots!<img src="https://media.weathernationtv.com/app/uploads/2023/03/3-30 RNC snow accum-1680230507580.JPG">Blowing snow will make it difficult to drive as well, even in areas that don't receive the highest snow amounts. I-29 and I-90 in South Dakota will be most impacted, but anywhere where snow is falling or can be blown around by gusty winds will be at risk for dangerous driving conditions due to near zero visibility.Any amount of ice accumulation can be dangerous on bridges and overpasses, even a glaze. Ice is likely throughout eastern South Dakota and Minnesota, but the highest amounts of ice will be in central Wisconsin. Here, a quarter to even a half inch of ice is expected to build up over the course of this event. Windshields can become coated, and watch for slick spots on bridges and overpasses. Half an inch of ice is usually when tree limbs and power lines have a hard time supporting the weight of the ice, and damage and power outages become more concerning.<img src="https://media.weathernationtv.com/app/uploads/2023/03/3-30 RNC ice accum-1680230711669.JPG">Torrential downpours leading to isolated flooding will be possible with this event as well. Soils are saturated from previous events, and it may not take a whole lot of additional rain to start seeing rivers and creeks rise. Low-lying areas will be more prone to flooding.Stay with WeatherNation for the most up-to-date conditions on the winter that won't end in the Central U.S. - your central regional forecast is always :30 past the hour.

Rob grew up in South Florida, where daily afternoon storms and hurricanes piqued his interest in meteorology early on. That interest was fostered by his teachers and his father, who one time brought him onto the roof of their home to watch a funnel cloud move through the Everglades several miles away. Years of filmmaking and tv production in high school gradually pushed him toward broadcast meteorology at Florida State University, where he joined and eventually led the student run daily weather show. After graduating with a Bachelors of Science in Meteorology, he began his career at KESQ in Palm Springs, California before heading to KFSN in Fresno and WLOS in Asheville, North Carolina. He has covered a diverse array of extreme weather events, including haboobs and flash flooding in the desert, extreme snow in the Sierra, hurricanes, and Appalachian ice storms. He also enjoys telling stories and reporting about weather issues.

There is a high fire danger threat through the Southern Plains and eastern Four Corners this week as an area of low pressure develops in the Lee of the Rockies, producing gusty winds and dry conditions for much of Colorado, New Mexico, Texas, and Oklahoma along with western Kansas.As a result, fire alerts are up for the area through the end of the week - please no outdoor burning (ABOVE). The Storm Prediction Center, which produces outlooks for severe weather, also produces fire outlooks; they have highlighted Thursday &amp; Friday as the most critical fire risk. Winds will be quite gusty, in the range of 20-30 mph with locally stronger gusts. Tie down anything that could blow away and be prepared for pockets of blowing dust and dirt.<img src="https://media.weathernationtv.com/app/uploads/2023/03/03-30 Fire Wind-1680196135500.JPG"><video src="https://media.weathernationtv.com/app/uploads/2023/03/2023-03-30 11-08-22-1680196148687.mp4" controls="true" width="100%"></video>Areas of west Texas, central Texas, Oklahoma, and Kansas are suffering under extreme and exceptional drought conditions. We will be concerned about any spark spreading quickly through dry brush and grass. Relative humidity values during the day will be in the single digits during the daytime hours, allowing flames to grow rather than dampen under the increased humidity of the atmosphere.<img src="https://media.weathernationtv.com/app/uploads/2023/03/drought-1680104472408.JPG">Here are some tips on preventing the spark of wildfires: Properly dispose of lit matches, cigarettes, or cigars. Avoid using equipment that causes a spark. Obey local burn bans by postponing any prescribed burns you may have had. If allowed to burn, make sure campfires are completely extinguished, cool to the touch!<img src="https://media.weathernationtv.com/app/uploads/2023/03/8-1680216396828.jpg">For the latest on the fire danger and wind in the Southern Plains, join WeatherNation, streaming 24/7.

The same storm system that is impacting California with heavy mountain snowfall and coastal rain is also bringing snow to the northwest. Winter alerts are now beginning to expire for the Northern Rockies. However, we have more alerts being issued out ahead of the next round of snow for the weekend. <video src="https://media.weathernationtv.com/app/uploads/2023/03/Futurecast Now-1680231927041.mp4" controls="true" width="100%"></video>As the area of low pressure pushes inland, more snow will arrive in the Bitterroots and northern Rockies. Heavy snow and gusty winds will make travel difficult at times. The second system arriving later on Friday brings a round of coastal and low elevation rain before the heavy mountain snow sets in.<img src="https://media.weathernationtv.com/app/uploads/2023/03/10-1680216526575.jpg">Generally, about 6-12" of snowfall is expected for the highest peaks of the Cascades and the Bitterroots. Those in the valleys and coast will get around an inch of rain, with higher totals possible in isolated spots.<img src="https://media.weathernationtv.com/app/uploads/2023/03/11-1680216556195.jpg">For Friday, temperatures during the day will be in the 40s and 50s for our major cities and the 30s in the mountains. This is slightly below average for this time of year. <img src="https://media.weathernationtv.com/app/uploads/2023/03/1-1680232052013.jpg">The grand snow totals through the weekend could top 2-4 feet on the highest peaks!

Another area of low pressure is pushing onto the west coast bringing another batch of rain and heavy mountain snow. We have had an incredible snow season and snowpack continues to rise in the Sierra, inching closer to the snowiest year in recorded history, 1952-53. We are about 10 feet shy of the snow totals of that winter! Additionally, these systems have been creating isolated strong thunderstorms and very heavy rain.However, Mammoth Mountain has recorded its snowiest season ever! 695" is almost 58 FEET of snow!<img src="https://media.weathernationtv.com/app/uploads/2023/03/3-29 RSW mammoth-1680119668624.JPG"><h1>Alerts</h1>Winter weather alerts are in place through today. We have a winter weather advisory and a winter storm warning. We can see heavy snow for elevations 5,000 feet and higher. The winter storm warning is in place for the Eastern San Gabriel mountains, here you can see snow accumulations of up to a foot possible and winds gusting up to 45 mph. Travel can be impacted. <img src="https://media.weathernationtv.com/app/uploads/2023/03/today-1680177953830.jpg"><h2>Forecast</h2>A surface low will move through today and help in the development of more rain showers, for cities including Los Angeles.

Are you headed into the High Country over the next few days? Be aware that the avalanche danger is considerable due to snowpack, melting, and weak slopes. Sadly, an avalanche in Utah, SW of Salt Lake City killed a snowmobiler on Monday. He was wearing an avalanche backpack and beacon that deployed an air bubble around him during the avalanche, but the snow and power of the slide were incredibly deep. With more snow on the way this week, the avalanche threat continues. Our next round of snow is headed into the Rockies tonight, with the potential for mountain snowfall on Thursday in both Utah and Colorado.<img src="https://media.weathernationtv.com/app/uploads/2023/03/winter warn 0330-1680185370887.JPG">Snow has begun with a weak system through Utah and becomes more widespread into Colorado overnight and into the first part of Thursday. A lot will depend on the timing of the system out of California, but we expect difficult travel on I-70 and I-80 starting Wednesday. Most snow showers will wind down by midday Thursday with just a few showers lingering into the overnight and first part of Friday in Colorado.<video src="https://media.weathernationtv.com/app/uploads/2023/03/4corn2-1680144187289.mp4" controls="true" width="100%"></video>Snowfall totals in the high country will be in the range of 3-6" with locally higher amounts based on elevation and our heaviest snow showers. Stay weather aware if you are traveling or headed into the mountains to ski as snow will reduce visibility and make roadways slick.<img src="https://media.weathernationtv.com/app/uploads/2023/03/skicast 0330-1680185453219.JPG"><img src="https://media.weathernationtv.com/app/uploads/2023/03/skicast 2 0330-1680185507035.JPG">Stay with WeatherNation for the latest system to impact the Rockies!

Avalanche Risk Remains Considerable Through the Rockies With More Snow This Week

0330RickiesAvyJPG-1680193500117.jpeg

It was 75 years ago January 22, 1943 when Spearfish, SD. set and still holds the record for fastest temperature change.

<img class="alignnone size-large wp-image-86584" src="https://media.weathernationtv.com/app/uploads/2018/01/Spearfish-map-728x408.jpg" alt="" width="728" height="408" />

That day started out very cold in Spearfish, and at 7:30 am MST the temperature recorded was -4°F.  
At that time Chinook winds picked up speed and two minutes later at 7:32 am the temperature rose to +45° F.  This was a 49° increase in just two minutes that is a record that still stands.

Temperatures continued to rise and at 9:00 am the temperature reached +54° F. As the chinook winds died down and 27 minutes later the temperature dropped 58° F back to -4° F.

The rapid temperature fluctuation that day caused glass windows to crack and instantly frosted car windows.

<img class="alignnone size-large wp-image-86589" src="https://media.weathernationtv.com/app/uploads/2018/01/SF-SD-1-487x408.jpg" alt="" width="487" height="408" /><img class="alignnone size-large wp-image-86588" src="https://media.weathernationtv.com/app/uploads/2018/01/F-SD-2-495x408.jpg" alt="" width="495" height="408" />

<img class="alignnone size-large wp-image-86587" src="https://media.weathernationtv.com/app/uploads/2018/01/SF-SD-3-461x408.jpg" alt="" width="461" height="408" />

Spearfish holds another winter maximum temperature record as well.  On January 19, 1921 the temperature soared to 79° F which is the hottest January temperature on record for the entire state. 

&nbsp;

More on Chinook Winds

&nbsp;

Downslope or “<a href="https://en.wikipedia.org/wiki/Foehn_wind">foehn winds</a>” are fairly common along mountain ranges and are often called  “Chinook” winds or even “snow eater” because they can melt and evaporate snow rapidly with very warm and dry air.

<img class="alignnone size-full wp-image-84008" src="https://media.weathernationtv.com/app/uploads/2017/11/classic-downslope-event.gif" alt="" width="400" height="200" />

When moist winds from the west are forced to rise over higher elevations of a mountain range, the air cools, moisture in the air is condensed and falls out as precipitation.  The phase change from water vapor to liquid or frozen water releases heat into the air.  As stated, when the air is forced to rise over higher elevations it expands and cools.  That cooling is somewhat hindered by the <a href="https://en.wikipedia.org/wiki/Latent_heat">latent heat</a> released by condensation.  The air pushed up the windward side of the mountains will cool at the moist adiabatic lapse rate of around 3.5 °F / 1000 ft although this lapse rate varies depending on how much moisture there is. The moisture removed from the air will leave it much drier for it’s trip to lower elevations on the leeward side of the mountains. The dried air then descends on the leeward side of the mountains, warming at the dry adiabatic rate of 5.5 °F / 1000 ft.  This just means that the heat added to the air on its way up through condensation will be added to the warmth as it descends to lower elevations. 

Air temperatures west of the mountains can be much colder than locations east on the plains once the down slope is underway.
