Rockville, MD Weather

This week's forecast brings a mix of weather conditions across the U.S. Expect storms in the Northeast and Midwest, with flash flooding risks in some areas. The South will experience high heat with temperatures soaring into the triple digits. Meanwhile, the Southwest will see scattered thunderstorms that may lead to localized flooding.

Storms and Flooding Threats

Northern Plains, Midwest, and Ohio Valley: Expect widespread thunderstorms from Sunday through Tuesday. A high-pressure system over the Southeast is pulling moist air into these regions, which will cause storms and the potential for flash floods. Northeast Missouri and Central Illinois are under a moderate risk of flash flooding, while areas from northern Missouri to the central Appalachians face a slight risk. As we move into Monday, the cold front will shift, increasing rainfall risks in the Ohio and Tennessee Valleys. By Tuesday, the risk moves to the Upper Midwest, impacting Northern Minnesota, Northern Wisconsin, and the Michigan Upper Peninsula.

Northeast: Severe storms are likely today with potential for damaging winds, large hail, and even tornadoes. Major cities like New York, NY, Hartford, CT, Providence, RI, and Boston, MA could experience flash flooding.

Southwest: Scattered thunderstorms are on the cards each afternoon and evening through Tuesday, particularly affecting parts of Arizona, New Mexico, West Texas, and Colorado. These storms could cause localized flash flooding, especially in areas with rugged terrain or burn scars.

Heatwave Alert

Central Plains, Lower and Middle Mississippi Valley, and Southeast: Brace yourselves for sweltering temperatures and high humidity. The Southeast will anchor hot conditions, with heat indices ranging between 105°F and 110°F, and some areas reaching above 115°F. Extreme Heat Warnings and Watches are in effect from Sunday through Monday, with the heat spread likely reaching into the Midwest by mid-week. Stay hydrated and cool!
