While the severe thunderstorm risk ends with the latest system pushing off the Atlantic Coast, another potent upper trough will move into the middle states by the middle of next week. The Storm Prediction Center is already highlighting an area of potential severe weather Wednesday through Friday, from the Plains to the Lower Mississippi River Valley.<img src="https://media.weathernationtv.com/app/uploads/2026/04/Screenshot 2026-04-18 192833-1776562725783.png">This upper-level low will bring strong winds aloft, enhancing shear for any storms that are able to form in the environment. This turning of the winds as you go up in the atmosphere will help organize those storms.<img src="https://media.weathernationtv.com/app/uploads/2026/04/Screenshot 2026-04-20 035121-1776678696660.png">Meanwhile, at the surface, heat and humidity will build during the afternoons, creating an unstable atmosphere. Storms that form will strengthen quickly!<video src="https://media.weathernationtv.com/app/uploads/2026/04/2026-04-21 03-50-02-1776765030526.mp4" controls="true" width="100%"></video>Long-range, less resolute models fire thunderstorms each afternoon, beginning Wednesday. With more rounds of rain moving over similar locations, flooding will need to be monitored as a potential threat. The WPC Excessive Rainfall Outlook has highlighted the threat of heavy rain from the Central Plains to the Southeast on Thursday and Friday.<img src="https://media.weathernationtv.com/app/uploads/2026/04/Screenshot 2026-04-21 035041-1776765059366.png">

<h1>SOUTHEAST</h1>Over 97% of the Southeast is in moderate to exceptional drought. These dry conditions have been one of many factors increasing the fire threat across the southeast. Over the next few days, we can see gusty conditions combined with the drought, which will aid any fires that start rapidly! Red flag warnings and fire weather watches remain in place through Tuesday. If you are in a local burn ban, please use caution and obey!<img src="https://media.weathernationtv.com/app/uploads/2026/04/Screenshot 2026-04-21 035333-1776765226743.png">Because of these dry conditions, we have seen multiple wildfires break out. On Sunday, fire crews responded to the N. Main Street Fire in Gainesville, Florida. As of now, this fire is 25 percent contained. Another, larger fire was burning near St. Augustine, torching over 3,000 acres. <img src="https://media.weathernationtv.com/app/uploads/2026/04/Screenshot 2026-04-21 104423-1776789878347.png"><h1>CENTRAL PLAINS</h1>Across the plains, gusty winds, dry conditions, and drought will all contribute to extreme fire conditions. Red flag warnings and fire weather watches are in place this week, as any fire that develops can spread rapidly! Please use extreme caution if you are doing any burning, and check to make sure you are allowed to burn.<img src="https://media.weathernationtv.com/app/uploads/2026/04/Screenshot 2026-04-21 035454-1776765307843.png"><img src="https://media.weathernationtv.com/app/uploads/2026/04/plains drought-1776713890395.png">

Flooding turned serious over the last week across Michigan and Wisconsin. Heavy rain &amp; severe storms arrived on top of spring snowmelt. <div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="2045208169664913798" src="https://x.com/WeatherNation/status/2045208169664913798"></div>A big part of this flood set up traces back to the Michigan's Upper Peninsula, where a very snowy winter left a large amount of water locked in the snowpack. <img src="https://media.weathernationtv.com/app/uploads/2026/04/Web_1-1776694765560.png">At the same time, Milwaukee set a new April precipitation record by April 16, surpassing the old record of 7.38 inches from 2013. &nbsp;<img src="https://media.weathernationtv.com/app/uploads/2026/04/Web_4-1776695176771.png"><div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="2044823132792365142" src="https://x.com/WeatherNation/status/2044823132792365142"></div>The flood threat is not over yet. The National Weather Service in Marquette said Monday that the threat for river flooding will continue across north-central and eastern Upper Michigan as temperatures warm into the 40s, and its latest flood briefing said minor to moderate flooding is expected over the next seven days, with major flooding possible along parts of the Sturgeon and Muskegon Rivers. <img src="https://media.weathernationtv.com/app/uploads/2026/04/Web_7-1776695604663.png">For more on your central regional forecast, tune into WeatherNation :30 past the hour.
