Slow Moving System to Produce Additional Heavy Rain in the South

Deep moisture associated with a slow moving system may produce locally heavy rain and flash flooding in the Lower Mississippi Valley. Three to six inches of rain can be expected, with isolated amounts as high as 10 to 15 inches. Severe storms could produce very large hail and damaging winds in the North Plains. Dry, Gusty winds continue to produce critical fire weather threats in the Great Basin.

Hot in the North-central and Northeast U.S.; Dry and Windy in the Great Basin

Heat Advisories are in place across portions of the Northeast states through Monday due to the combination of hot temperatures and high humidity. Heat Advisories are also in place for the Minneapolis/St. Paul metro area through Thursday. Critical fire weather conditions are forecast through Wednesday across portions of the Great Basin.

Southern Storms and Heavy Rain; Persistent Western Heat

Slow moving weather systems may produce isolated severe thunderstorms and heavy rain in the Lower and Middle Mississippi Valleys, and portions of the South Plains into the Central High Plains. Strong high pressure in the West continues to produce record breaking heat and elevated fire weather threats. Dangerously hot conditions are present across interior California and the Desert Southwest.

Soggy and Stormy in the South Plains; Summer Heat in the West

Strong to severe thunderstorms with damaging winds, large hail, and heavy rain will persist in the South Plains. Additional rain on saturated soils may produce flash flooding, especially, across north-central Texas. A heat wave in the West will reach dangerous levels into the triple digits for some locations. Elevated fire weather threats are in place for portions of interior California.

Severe Weather Outbreak in the Central Plains; Thunderstorms with Damaging Winds in the Northeast

A regional outbreak of severe thunderstorms is expected across the central Great Plains through tonight. In the East, severe thunderstorms are also possible from portions of Virginia to Maine with mainly a damaging wind threat. A few record high temperatures are also possible across the East today.

Showers and Thunderstorms Across the Central Plains and the Northeast

Scattered severe thunderstorms and heavy rains are possible across parts of the Great Plains where damaging wind gusts, large hail, and a couple of tornadoes are possible. Scattered severe thunderstorms will also be possible across parts of the central and northern Appalachians. Record high temperatures are possible along the East Coast.

Widespread Heavy Rainfall to Continue Flooding Threat For South-Central U.S. This Week

Multiple days of heavy rainfall will likely continue to cause considerable flash and urban flooding impacts across portions of eastern Texas, Oklahoma, western Arkansas, and extreme western Louisiana this week. New and renewed widespread minor to isolated major river flooding is expected, and will continue into next week on slow-to-drain rivers.

Isolated Thunderstorms and Heavy Rains from the Southern Plains to the Southeast

Isolated strong to severe storms capable of producing large hail and damaging wind gusts may occur across parts of the southern Plains into the Southeast. Heavy rains may cause localized flash, urban, and small stream flooding from the Southern Plains across the Lower Mississippi Valley through Wednesday. Elevated fire weather conditions continue across the Southwest and northern California.
