Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 354 AM EDT Tue Jun 25 2019 Valid 12Z Tue Jun 25 2019 - 12Z Thu Jun 27 2019 ...Severe weather possible for parts of the Central Plains to Middle Mississippi Valley and Midwest... Overall, a quieter weather pattern is in store for the U.S. over the next couple of days, as the trough that has been causing active weather across the central and eastern U.S. lifts into Canada and the jet stream becomes generally zonal. The main weather threat on Tuesday will be severe weather--thunderstorms are forecast to form along and ahead of a front in the Central Plains, Middle Mississippi Valley, and into the Upper Midwest to Upper Great Lakes region. A Slight to Enhanced Risk of severe weather is in effect for these areas from the Storm Prediction Center. Farther south, scattered summertime thunderstorms are expected in the Southern Plains into the Lower Mississippi Valley and Southeast on Tuesday and Wednesday. A few strong thunderstorms are possible there, along with some potential for localized heavy rainfall and flash flooding as plenty of moisture streams in. The Northeast could see thunderstorms containing heavy rainfall on Tuesday as well, as a low pressure system and associated cold front traverse the region before moving off the East Coast on Tuesday night. By Wednesday and Thursday, an upper-level low edges into the Pacific Northwest, causing the possibility of showers and thunderstorms in the Northwest. Farther south through, elevated fire weather conditions are expected on Tuesday and Wednesday in parts of the West and Southwest as the increase in winds combine with dry relative humidities. The upper low will cool down temperatures along the West Coast, with high temperatures forecast to be below average by 10 to 20 degrees. Meanwhile, the Central Gulf Coast to Florida and the eastern Carolinas are expecting temperatures above their already warm summertime averages, with highs in the 90s and heat indices in the 100s.
