<p>Confidence is increasing in the threat of widespread strong to severe thunderstorms erupting across the southern Plains by Thursday afternoon. The threat will continue into Friday.</p><h1>Setup</h1><p>In the upper levels, another potent trough will dig into the southwest from California. This upper-level energy will overspread a warm and unstable airmass, characterized by high humidity, transported on a southerly wind from the Gulf. </p><p><img src="https://media.weathernationtv.com/app/uploads/2023/03/Capture-1679855553414.JPG"><img src="https://media.weathernationtv.com/app/uploads/2023/03/Capture2-1679855578170.JPG"></p><p>Ample amounts of wind shear along with surface instability should result in vigorous thunderstorm development by the afternoon. All hazards of severe weather will be possible.</p><h1>Timing</h1><p>Although thunderstorm activity is expected by Thursday afternoon, the timing of formation along with the amount of storm coverage is yet to be determined. Confidence is higher in more widespread activity by Friday as the main upper-level energy swings through.</p><p>The Storm Prediction Center has highlighted much of the southern Plains into the Midwest for severe weather potential by the end of the week.</p><p><img src="https://media.weathernationtv.com/app/uploads/2023/03/Capture3-1679855815540.JPG"></p><p><img src="https://media.weathernationtv.com/app/uploads/2023/03/Capture4-1679855824268.JPG"></p><h1>Tis the Season</h1><p>We're still a few days out, so some details will need to be worked out. However, it is never too early to prepare, especially this time of year!

<p>With the jet stream focused over the Midwest, the weather has been active across Illinois, Indiana, and Ohio. We have seen snowy conditions along with widespread severe weather. Wind reports in Pennsylvania and Ohio have been upwards of 60-70 mph on Saturday!</p><p>Another quick-moving low-pressure system will help spark a few more storms Sunday through the Midwest. Damaging winds are our primary threat but we can't rule out an isolated tornado either.</p><p>Another round of storms develops around an area cold front and low-pressure system, focused more into Indiana and Illinois with all modes of severe weather possible once again. Even if a storm does not reach severe criteria, heavy rain will still be a factor, along with gusty straight-line winds.</p><p></p><p><img src="https://media.weathernationtv.com/app/uploads/2023/03/Capture-1679854652933.JPG"><img src="https://media.weathernationtv.com/app/uploads/2023/03/Capture-1679854701502.JPG"><img src="https://media.weathernationtv.com/app/uploads/2023/03/CaptureJPG-1679854122466.jpeg"></p><h1>Forecast Timing</h1><video src="https://media.weathernationtv.com/app/uploads/2023/03/indy-1679854824677.mp4" controls="true" width="100%"></video><p>With multiple rounds of heavy rain expected, there is growing concern for flash flooding.

Taban Sharifi grew up in Southern California between Los Angeles and San Diego. She is a Certified Broadcast Meteorologist (CBM) with the American Meteorological Society (AMS). She has a B.S. in Atmospheric, Oceanic, and Environmental Sciences with a minor in Environmental Systems and Society from the University of California, Los Angeles (UCLA). Go Bruins! While in school, Taban was a meteorology intern with NBC LA. There she helped forecast daily weather for the greater Los Angeles region and created a playbook to deploy weather sensors for NBC owned-and-operated stations across the country. Her first on-air job took her to San Angelo, Texas, where she was a morning meteorologist and co-anchor. Working in West Texas gave her knowledge and experience covering severe storms. From there, she moved to Palm Springs, California. People think forecasting in California is sunshine all the time, but with temperatures in the 120’s, wildfires, damaging winds, floodings, and earthquakes, the forecasting kept her very busy! She also worked there as a general assignment reporter and told community stories. Taban is excited for the challenge and opportunity to forecast nationally with WeatherNation. She also looks forward to exploring all that Colorado has to offer!

<p>Snow has fallen in the Denver metro and back through the Rockies on Saturday, producing a few inches of fresh snowfall with higher mountain totals. This area of low pressure has moved into the Great Plains of Nebraska and Kansas on Sunday, bringing additional snowfall. Parts of Nebraska have already seen totals in the last 24 hours of 10 inches.</p><p>The snow is gradually winding down this afternoon, however, there is an additional low-pressure system that will organize out of Colorado Monday. This system will have the potential to bring additional heavy snow to parts of western Nebraska and eastern Colorado throughout the day. </p><video src="https://media.weathernationtv.com/app/uploads/2023/03/0326 plains snow-1679823270893.mp4" controls="true" width="100%"></video><p>In addition to the accumulating snow, gusty winds could lead to drops in visibility and difficult driving conditions on I-80 in western Nebraska.<img src="https://media.weathernationtv.com/app/uploads/2023/03/plains snwo-1679823290831.JPG"></p><p>Stay with WeatherNation for the latest on the snow threat your central regional forecast is always :30 past the hour.</p>

<p>The same front that spawned the severe storms and tornadoes in Mississippi on Friday and the large hail producing storms Saturday, hangs around Sunday, prolonging the severe weather threat for the Gulf Coast.</p><p>The Storm Prediction Center has issued an ENHANCED risk (Level 3 out of 5) through southern Mississippi and Alabama on Sunday, a bit further south than where the strongest of the storms hit on Friday. Still, for some communities impacted by the storms Friday, the risk of heavy rain and strong winds will lead to difficulty with cleanup efforts.</p><p><img src="https://media.weathernationtv.com/app/uploads/2023/03/new svr-1679849224624.JPG">Wind and hail will be the most widespread threats with Sunday's storms, especially in the Enhanced Risk region. Tornadic activity will also be possible with a significant tornado threat. This means there will be the possibility of an EF-2 in strength of stronger in the highlighted red region.</p><p><img src="https://media.weathernationtv.com/app/uploads/2023/03/new svr2-1679849228447.JPG">Very large hail is possible across central Louisiana through South Carolina Sunday afternoon and evening. Here, the environment is supportive of 2" thick hail, or larger. This equates to lime or hen egg size hail, which can do significant damage to property.</p><p><img src="https://media.weathernationtv.com/app/uploads/2023/03/new svr4-1679849247462.JPG">Storms will fire up early in the morning, with multiple rounds of storms possible through the day. Showers and storms continue to develop through the afternoon and evening along the front, becoming much more widespread along the I-20 corridor overnight Sunday into Monday. Please have multiple ways to get alerts as storms roll through overnight and remember that flash flooding can be deadly, and nighttime flooding is extremely dangerous.</p><video src="https://media.weathernationtv.com/app/uploads/2023/03/0326-1679822806219.mp4" controls="true" width="100%"></video><p>Rainfall totals could top 3-6 inches where thunderstorms train over the same location, leading to flood potential. Flash flooding is an equally dangerous and deadly threat with the severe storms, especially close to rivers, creeks, streams as well as urban communities. Please, turn around, don't drown.</p><p><img src="https://media.weathernationtv.com/app/uploads/2023/03/1-1679772296671.jpg">The Weather Prediction Center (WPC) has upgraded the Excessive Rainfall Risk to a Moderate (level 3 out of 4).</p><p><img src="https://media.weathernationtv.com/app/uploads/2023/03/excessive rain-1679848610772.JPG">Monday, a marginal risk of severe storms will be possible as these storms continue East. The risk for tornadoes, high winds, and large hail will be less compared to Sunday, but it will still be present.</p><p><img src="https://media.weathernationtv.com/app/uploads/2023/03/MON SVR-1679822846104.JPG">Stay with WeatherNation for the latest in the severe weather and flood threat this weekend and early next week in the south.</p>

<p>CALIFORNIA - We have had a incredible snow season and there is no sign of things slowing down in the near future. Snowpack continues to rise in the Sierra, and is inching closer to the snowiest year in history of 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.</p><h2>Freezing Conditions</h2><p>It's been a chilly last few mornings, and Monday morning will be no exception. Temperatures will once again drop in to the 20s and 30s, so please cover exposed plants or bring them inside. The cold air could be harmful for plants that are already into the growing season, especially for agriculture.</p><p><img src="https://media.weathernationtv.com/app/uploads/2023/03/freeze-1679847104102.JPG"></p><h2>Next Wave Monday - Wednesday</h2><p>Looking ahead to the next work week, another round of wet weather is on the way. A Pacific low will move onshore, bringing more moisture to waterlogged California. There is confidence in meaningful snow for the Sierra, which will help creep up closer to the snowiest season on record. Winter storm watches are in effect for the Sierra from Monday night into Wednesday with heavy snow anticipated over 3000 feet. <img src="https://media.weathernationtv.com/app/uploads/2023/03/cali-1679847125101.JPG"></p><h2>Forecast Accumulation</h2><p><img src="https://media.weathernationtv.com/app/uploads/2023/03/cali precip-1679847143920.JPG">In addition to snowfall, we expect heavy rain to be a concern along the coastline, prompting more flood alerts and the risk of mudslides &amp; debris flow.<img src="https://media.weathernationtv.com/app/uploads/2023/03/cali rain-1679847156856.JPG"></p><h2>Forecast Timing</h2><video src="https://media.weathernationtv.com/app/uploads/2023/03/032623 cali-1679847247103.mp4" controls="true" width="100%"></video><p>The extended pattern into the beginning of April remains active in the western U.S. with above average rain and snow conditions expected.</p><p>Stay with WeatherNation for the latest in the snow amounts and timing for the Western U.S., the Western regional forecast is at :50 past the hour!</p>

<p>A ridge of high pressure in the Gulf of Mexico is providing near record warmth and Gulf moisture in the Southeast, increasing the risk of severe weather as a cold front and surface low pressure system push through tonight. Severe storms are expected to continue tonight with the potential for damaging winds and tornadoes. </p><p><img src="https://media.weathernationtv.com/app/uploads/2023/03/03-25 Tor D1-1679765609052.JPG">The potential for severe storms will continue into the evening through the Carolinas and Georgia, before another round potentially starts in the overnight farther west into Alabama and Mississippi along the I-20 corridor.</p><video src="https://media.weathernationtv.com/app/uploads/2023/03/Futurecast-1679772946494.mp4" controls="true" width="100%"></video><p>Records did occur on Thursday &amp; Friday across the South with highs in the 80s and 90s. Records broke on Friday for cities like Baton Rouge and Greenwood. Everywhere there is a pink dot is an opportunity to tie or break records Sunday and Monday.

<p>Another low-pressure system moving through the central U.S. will encounter cold air in our atmosphere and has been producing heavy snow and wind in the northern tier of the country. Snow alerts continue in northern Michigan and northern Maine tonight. Winter weather alerts continue Sunday with snow up to 10 inches and sleet up to .25". The winter storm warning is where we can see the highest snowfall totals. Rainfall totals of up to an inch are possible.</p><p><img src="https://media.weathernationtv.com/app/uploads/2023/03/1-1679774540321.jpg"> <img src="https://media.weathernationtv.com/app/uploads/2023/03/1-1679739436162.JPG">Steady snow will continue through New England while tapering in the Great Lakes region as cold air and snow wrap around the back side of the low-pressure system Saturday before tapering down early Sunday morning. Snow totals will be heaviest through northern New England where locally up to 6" may be possible. Most in the mountains will see light accumulations though.</p><video src="https://media.weathernationtv.com/app/uploads/2023/03/Futurecast-1679773328966.mp4" controls="true" width="100%"></video><p>We will see another 3-6" of snow in northern Maine and across far northern Michigan and the U.P..</p><p><img src="https://media.weathernationtv.com/app/uploads/2023/03/1-1679773398794.jpg"></p><p><img src="https://media.weathernationtv.com/app/uploads/2023/03/2-1679774483509.jpg">Looking deeper into the forecast, there is another round of winter precipitation for next Tuesday and Wednesday. There is still a bit of uncertainty in the forecast, especially when it comes to temperature profiles, which determines if we get wet, heavy snow, or sleet and freezing rain.

Heavy Snow for the Great Lakes and Northeast Tonight

GLsnowfallJPG-1679780141133.jpeg

Canadian air has been digging into the Pacific Northwest over the last few days. This has allowed cooler than average temperatures to take over in parts of Idaho and Montana to support high elevation snow chances.

<img class="alignnone size-full wp-image-127655" src="https://media.weathernationtv.com/app/uploads/2020/08/08-31-snow-set-up.jpg" alt="" width="1920" height="1080" />

An upper level trough coming out of Canada has allowed for some of the Pacific moisture to fall as light valley rain and high mountain snow. This is one of the first snowfalls of the season with only light accumulations possible in the higher elevations.

<img class="alignnone size-full wp-image-127656" src="https://media.weathernationtv.com/app/uploads/2020/08/08-31-trough.jpg" alt="" width="1920" height="1080" />

<img class="alignnone size-full wp-image-127658" src="https://media.weathernationtv.com/app/uploads/2020/08/08-31-Forecast-snow-1.jpg" alt="" width="1920" height="1080" /><img class="alignnone size-full wp-image-127657" src="https://media.weathernationtv.com/app/uploads/2020/08/08-31-snow-forecast-2.jpg" alt="" width="1920" height="1080" />

High temperatures this afternoon are roughly 15 to 20 degrees cooler than they typically are for the end of August. Again, the higher peaks are where the dusting is possible as it is still too warm for valley snow.

<img class="alignnone size-full wp-image-127654" src="https://media.weathernationtv.com/app/uploads/2020/08/08-31-MT-Mountain-highs.jpg" alt="" width="1920" height="1080" />

Tonight, Frost Advisories and Freeze Warnings have been issued as temperatures are expected to fall sub-freezing (as low as 28 degrees) in parts of the mountains in Idaho and Wyoming.

<img class="alignnone size-full wp-image-127659" src="https://media.weathernationtv.com/app/uploads/2020/08/08-31-freeze-alerts.jpg" alt="" width="1920" height="1080" />

Temperatures don't remain cooler than average for long. They will be rebounding in the Northwest with highs returning to average by midweek.
