Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 329 PM EDT Thu Jun 13 2013 Valid 00Z Fri Jun 14 2013 - 00Z Sun Jun 16 2013 ...Severe weather threat will diminish through the late evening hours across the Mid-Atlantic... ...Showers and thunderstorms moving from the northern Rockies to the Upper Midwest... The threat for severe weather and flash flooding across the Mid-Atlantic today will diminish during the late evening once the sun goes down. Some mainly scattered rain and thunderstorms could continue to be supported along the coast and into the Southeast as the front moves off the Mid-Atlantic coastline overnight tonight. More moderate precipitation wrapped around the surface low is still possible in southern New England tonight and early Friday morning as well. Behind this system, high pressure will move in bringing cooler and dryer air with it on Friday and into the weekend. Meanwhile, an upper trough carving into the Northwest U.S. will continue to bring precipitation to the Northern Rockies on Friday. Once the frontal system pushes east of the Rockies on Friday, showers and thunderstorms will develop in the northern Plains and eventually the Midwest. Some of the thunderstorms could bring some heavier rainfall as well as the threat for severe weather. Elsewhere, an upper ridge will remain across the central and southern Plains keeping the warm and above normal temperatures in place for much of the forecast period. Additionally, weak energy moving out of northern Mexico and into Texas could trigger some showers and thunderstorms across southern and western Texas and into eastern Colorado.
