Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 533 PM EDT Sat Jun 22 2013 Valid 00Z Sun Jun 23 2013 - 00Z Tue Jun 25 2013 ***Stormy weather over the Northern U.S.*** ***Scattered showers and storms for the Southeast*** ***Unusually wet pattern for the West Coast*** The most active weather across the U.S. is expected over the central and northern Plains, and into the Upper Midwest. Shortwave energy entering the Plains from the Rockies, along with a few frontal boundaries, will allow for the development of several organized thunderstorm complexes. Some of these storms could be severe and produce heavy rainfall. Out West, an anomalous trough along with a couple of cold fronts moving in from the Pacific Ocean will establish a weather pattern conducive for abnormally high rainfall for late June over the northern half of California and extending northward into the Pacific Northwest. The highest rainfall amounts should be focused on the westward facing mountain slopes where the forcing should be the greatest. Over the Southeast U.S. and Florida, a weak upper level low will slowly lift northeastward and out to the Atlantic by Monday, along with a weak surface trough. Deep southerly flow near this feature will allow for the development of numerous showers and thunderstorms from the central Gulf Coast to the Mid-Atlantic region, with the greatest concentration of rainfall near the Southeast coast.
