A strong upper-level low-pressure system moving east from California is triggering strong storms in the southern Plains, Deep South and Midwest this week. Storms look most intense late tonight in Texas and Oklahoma and through the day Friday as they track across the lower Mississippi Valley with significant hail, tornadoes, and damaging straight-line winds. A SEVERE THUNDERSTORM WATCH (above) is in effect for the Red River Valley and much of central and eastern Oklahoma into southern Missouri as storms develop around the area of low pressure tonight.Related Articles - <a target="_blank" rel="noopener noreferrer nofollow" href="https://www.weathernationtv.com/news/significant-severe-storm-risk-targets-the-deep-south-friday">Friday's Severe Weather Risk</a> and <a target="_blank" rel="noopener noreferrer nofollow" href="https://www.weathernationtv.com/news/strong-storms-flooding-target-the-midwest-now-through-friday">Severe Threat for the Midwest</a>The risk today stretches from the Rio Grande River to Indiana, with a higher risk from Tulsa through Del Rio.

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.

A strong low pressure system will continue to push east Friday across the Deep South with abundant energy for strong and severe storms. Near record warmth, plentiful moisture, and high wind shear will lead to numerous if not widespread severe storms during the afternoon and evening. The Storm Prediction Center has increased the risk to MODERATE (level 4 out of 5) Friday afternoon into the overnight across the borders of Louisiana, Arkansas, and Mississippi (ABOVE). Numerous tornadoes and widespread damaging winds are possible in this area. Tornadoes will be a concern, particularly for the region in red. In addition to the risk for numerous tornadoes, several strong tornadoes are possible (brown region below) that may be long lived, or on the ground for an extended period. EF-2 strength tornadoes have winds higher than 110 mph.<img src="https://media.weathernationtv.com/app/uploads/2023/03/tor-1679605089158.JPG"><img src="https://media.weathernationtv.com/app/uploads/2023/03/sig tor-1679605079299.JPG">Damaging winds could also be widespread across the region, including the chance for hurricane force gusts (region below). Secure loose belongings and tie down property that could be damaged or could become a projectile.<img src="https://media.weathernationtv.com/app/uploads/2023/03/sig wind-1679605127088.JPG">Storms will likely be ongoing early in the morning in Texas, Arkansas, and Oklahoma around the low and warm front. The stronger storms are expected from the early afternoon through the overnight as the cold front becomes the main trigger for severe storms. Storms become much more widespread into the afternoon with all modes of severe weather likely and dangerous, numerous storms along the Mississippi Valley.<video src="https://media.weathernationtv.com/app/uploads/2023/03/2023-03-23 06-14-15-1679573688326.mp4" controls="true" width="100%"></video>Check back with WeatherNation for the latest.

Strong Storms & Flooding Target the Midwest

Another low pressure system moving through the central U.S. will encounter cold air in our atmosphere and become a snow maker for the Upper Great Lakes this weekend. Once again we will be watching for difficult travel, low visibility and wet heavy snow that could cause isolated power outages. Winter alerts are in effect on Saturday for northern Michigan where there is increased confidence in the snow potential. <img src="https://media.weathernationtv.com/app/uploads/2023/03/mi alerts-1679605913634.JPG">This low pressure system is relatively warm with the severe weather and storm threat just to the south in central IL, IN and OH on Friday. This means we will see a wet, heavy snowfall and the risk of ice and sleet during the day on Friday before cold air meets the moisture and transfers more of the precipitation into snow. Snow will wrap around the area of low pressure through the day on Saturday, keeping Michigan and eastern Wisconsin unsettled and cold. <video src="https://media.weathernationtv.com/app/uploads/2023/03/2023-03-23 14-44-17-1679605988449.mp4" controls="true" width="100%"></video>The Global Forecast Model, or GFS for short, favors the snow axis from southern Wisconsin through Milwaukee and into northern Michigan with the heaviest pockets of snow through Cadillac, Traverse City and Alpena. The Baron model skews a bit further to the west with the heaviest snowfall, favoring more of Madison, WI, Green Bay and into the U.P. of Michigan. The exact axis of heaviest snowfall depends on the track of the low and where the low intensifies most, therefore leading to the higher snowfall pockets. <img src="https://media.weathernationtv.com/app/uploads/2023/03/gfs snow-1679605506758.JPG"><img src="https://media.weathernationtv.com/app/uploads/2023/03/baron model-1679605718201.JPG">Stay with WeatherNation for the latest in the snow forecast for the upper Great Lakes this weekend.

Winter Storm System to Hit the Upper Great Lakes this Weekend

A ridge of high pressure in the Gulf of Mexico is building warmth and moisture into the Southeast - a far cry from the freezing temps we saw earlier this week. We will see moisture and warm temps combo for the risk of severe weather by Saturday and stormy weather continuing into Sunday. Records did occur on Thursday across the South with highs in the 80s and 90s. <img src="https://media.weathernationtv.com/app/uploads/2023/03/1-1679628159931.jpg"><h2>Heat</h2>Everywhere there is a pink dot is an opportunity to tie or break records through the weekend and into early next week. Most of the records will be in Florida, but a few of our coastal cities will get a crack at well above average temperatures this week too. Highs will soar into the 80s with even some low 90s, potentially setting records each day this weekend. The heat will fuel strong storms though, and we have the risk of severe weather through the south on Friday. Be prepared for some rain showers along the Gulf Coast to finish out the week. Temperatures on Friday could be upwards of 10-15 degrees above average!<img src="https://media.weathernationtv.com/app/uploads/2023/03/se dots-1679604609498.JPG"><img src="https://media.weathernationtv.com/app/uploads/2023/03/se 3 day-1679604616308.JPG"><h2>Severe Weather</h2>Severe storms hold off until Saturday when the severe weather threat stretches from the Florida Gulf Coast into the Southeast, to include Montgomery, Columbus and Macon. All modes of severe weather are possible but we will be watching closely for damaging winds and waterspouts. Flooding will also be a threat.<img src="https://media.weathernationtv.com/app/uploads/2023/03/spc saturday-1679604602508.JPG">Stay with WeatherNation for the latest on the temperature swings and severe concerns, streaming 24/7!

Record Heat to Finish Out the Week in the Southeast Before Weekend Turns Stormy

CALIFORNIA - A tornado touched down in the Los Angeles suburbs on Wednesday afternoon as another atmospheric river and low-pressure system came to a close. This was in Montebello California, an eastern suburb of the city of L.A.. The National Weather Service office in Los Angeles rated this storm as an EF-1 and it caused 2 injuries. In addition to strong thunderstorms, we've seen heavy snowfall and heavy rainfall across the state of California. Additional heavy rain and snow is anticipated through Friday morning with an additional wave of energy pushing onshore today. This next wave will feature light snowfall accumulations, generally less than 6". Rainfall totals will be light as well, favoring the foothills and coastline with less than 0.5" of new rain.<img src="https://media.weathernationtv.com/app/uploads/2023/03/winter alerts-1679583138131.JPG"><img src="https://media.weathernationtv.com/app/uploads/2023/03/new snow-1679583147985.JPG">After the rain and snow on Friday we are looking at a quieter weekend ahead, but much cooler too. In fact, temperatures will drop into the 30s and 40s for the central Valley overnight, prompting frost and freeze alerts. The cold air could be harmful for plants that are already into the growing season.<img src="https://media.weathernationtv.com/app/uploads/2023/03/frost freeze-1679583500975.JPG">Looking ahead to next week we have another round of wet weather on the way for California. Yet another area of low pressure moves ashore bringing Pacific moisture to waterlogged California. The Weather Prediction Center (WPC) has highlighted the threat for heavy rainfall along the coast and snowfall in the mountains for Monday into Tuesday. There is confidence in yet another meaningful snow event for the Sierra, which will creep up closer to the snowiest season on record. The incoming storm looks to be skewed a bit further north, impacting the northern Sierra and Cascades with the heaviest of the snowfall.<img src="https://media.weathernationtv.com/app/uploads/2023/03/cali extendced-1679606634539.JPG"><img src="https://media.weathernationtv.com/app/uploads/2023/03/gfs snow-1679583829476.JPG">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!

At WeatherNation, we're committed to educating and informing our viewers of all of the threats severe weather can bring. On March 1, the <a href="https://www.weather.gov/wrn/spring-safety">National Weather Service</a> initiates their campaign to prepare us for all of the hazards the Spring season can bring. Severe storms can happen anywhere in the U.S. at any time. Each day through the first week of March, we'll highlight different aspects of hazardous severe thunderstorms and what you need to know to stay safe.

In case you missed it, <a href="https://bit.ly/33YFdYG">we covered Tornado safety yesterday</a>.
<h1>WIND &amp; HAIL</h1>
Three things qualify a thunderstorm as severe. Tornadoes are one, wind and hail threats make up the other two, so lets break down those specific hazards.

How is hail measured? We break it down for you and show what everyday objects correspond with a certain hail size.
