Rounds of Severe Weather Target Midwest, Mid-Atlantic
August 30, 2024 at 12:53 AM EDT
By WeatherBug Meteorologist, Molly Robinson
A cold front will trigger severe thunderstorms across the Upper Midwest today, while dangerous storms could also develop along a stalled front in the Mid-Atlantic.
After bringing a round of severe thunderstorms to the Dakotas, a cold front will contribute to yet another batch of severe activity today in the Upper Midwest. With strong instability in place as well as brisk winds aloft and the cold front acting as a trigger, severe thunderstorms will likely develop this afternoon and evening.
The Storm Prediction Center has issued an Enhanced Risk for severe weather today over east-central Minnesota and far west-central Wisconsin. This includes Minneapolis. A larger Slight Risk covers the rest of Minnesota south to northern Iowa as well as western Wisconsin. This includes Rochester, Minn., Mason City, Iowa, Eau Claire and La Crosse, Wis.
The primary threats will be quarter-sized hail and wind gusts exceeding 55 mph. However, a few tornadoes also cannot be ruled out.
At the same time, a cold front will be stalled over the Mid-Atlantic. Very warm, humid air will be found to the south of the front, while colder and drier air attempts to filter in behind hit. The collision of these air masses will likely trigger thunderstorms this afternoon and evening.
A Severe Thunderstorm Watch is in effect for south-central Pennsylvania, most of Maryland and northern Virginia. It includes Harrisburg, Pa., Cumberland and Frederick, Md., Washington, D.C., and Harrisonburg and Fredericksburg, Va.
Another Slight Risk for severe weather has been issued for central Pennsylvania, parts of Maryland and northern Virginia, which includes Washington, D.C. Here, thunderstorms could produce damaging winds exceeding 55 mph and quarter-sized hail
Make sure to frequently check WeatherBug for updates, as a watch can quickly turn into a warning upon imminent danger. It is important to stay prepared for active weather. Make sure you know the difference between a watch and a warning should they become issued. A watch means that conditions are favorable for severe weather to take place, whereas a warning means severe weather is imminent and you need to act fast to prevent damage to property or even loss of life. Remember, “When Thunder Roars, Go Indoors!”
