Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 413 PM EDT Thu Jul 30 2015 Valid 00Z Fri Jul 31 2015 - 00Z Sun Aug 02 2015 ...Drier conditions unfolding across the Northeast and Mid-Atlantic... ...Showers and thunderstorms to persist across the Southeast... ...Flash flooding possible for portions of the southwestern U.S into the Plains... ...Above average temperatures expected for the Pacific Northwest... A cold front, preceded by showers and thunderstorms, will continue to push through the remainder of the Northeast and Mid-Atlantic states this evening. While delivering drier air, typical summertime temperatures are expected to persist across much of the region through the remainder of the week. Further to the south, the front is expected to stall across the Southeast and along the Gulf coast back into Texas. Very moist, unstable air along and south of the boundary will continue to support showers and thunderstorms across the Southeast and central Gulf coast regions. While much of the activity is expected to be scattered in nature, weak disturbances aloft may help to produce some organized storms, particularly along the eastern and central Gulf coast regions. Further west, afternoon and evening showers and thunderstorms are expected to continue both days across portions of the southern Rockies, the Desert Southwest and southern California. Some of these storms may produce locally heavy amounts, resulting in excessive runoff and flash flooding. Some storms developing across the mountains of northern New Mexico and southern Colorado may propagate eastward, dropping heavy rains as they move into southwestern Kansas and the Oklahoma and Texas Panhandle regions. Across the Northwest, little change is expected over the next few days as high pressure at the mid and upper-levels of the atmosphere will keep dry conditions and above average temperatures in place across the region. Afternoon high temperatures will be as much as 10 to 15 degrees above average at many locations, with temperatures surpassing 100 degrees in some areas.
