Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 455 PM EDT Fri May 24 2013 Valid 00Z Sat May 25 2013 - 00Z Mon May 27 2013 ***Cool with showers over the Northeast states*** ***Scattered showers and storms over the Plains*** ***Large scale trough with showers out West*** The strong cold front that is now clearing the East Coast will bring a fresh surge of cooler and drier air to the Eastern U.S. for the Memorial Day weekend. The coldest conditions are expected for the central and northern Appalachians, where frost and freeze advisories and warnings are in effect. Over New England, the presence of a slow-moving surface low near the coast will create showers and breezy conditions through Sunday, thus making indoor plans a wise choice. Over the Central U.S. and Great Plains, an upper level ridge and return flow from the Gulf of Mexico will allow for warmer temperatures and isolated to scattered showers and thunderstorms. A few organized thunderstorm complexes may be able to develop, with isolated severe weather a possibility. Out West, below average temperatures are also expected in this region with an upper level low and increased cloud cover over the Pacific Northwest and into the Inter-Mountain West. The highest mountain ridges may even get some snow showers at times. Hamrick Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_wbg.php
