Flash Flooding Threat Increases Across Southeast Ohio, West Virginia, and the Central Appalachians
A Slight Risk of excessive rainfall is in place across parts of the Ohio Valley and Central Appalachians today, with the greatest concern from southeast Ohio through West Virginia and into eastern Kentucky, southwest Virginia, and northwest North Carolina. A cold front and several upper-level disturbances will trigger thunderstorms beginning this afternoon and continuing into the evening. Storms may produce rainfall rates of 1 to 2 inches per hour. Recent heavy rain has left soils saturated and streams elevated, so additional rainfall could quickly cause flash flooding. Scattered thunderstorms will also produce locally heavy rain across eastern Arizona and New Mexico, where isolated rainfall totals of 1 to 2 inches are possible. Farther north, thunderstorms may produce isolated flash flooding from Nebraska into southern Minnesota.

Elevated Fire Weather Conditions Expected in Portions of Northern California and Nevada
Warm, dry, and breezy conditions will create elevated fire weather concerns across parts of northeastern California and northern Nevada this afternoon. Southwest to west winds will remain around 10 to 15 mph while relative humidity falls to 15 to 20 percent. Critically dry fuels and little recent rainfall will increase the potential for fires to start and spread. Farther north, a disturbance moving through the Northern Rockies will trigger widely scattered thunderstorms this afternoon. Limited moisture and fast-moving storms could result in little rainfall, increasing the potential for lightning-caused fire starts despite recent wetting rainfall. New fires have already been reported in southwestern Idaho and eastern Oregon. An isolated dry thunderstorm is also possible farther south into Idaho, although the chance remains low.
