Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 426 PM EDT Sun May 25 2014 Valid 00Z Mon May 26 2014 - 00Z Wed May 28 2014 ...Heavy rains will deliver some relief to drought stricken regions of the southern Plains...but could also lead to flash flooding and severe storms... Organized areas of heavy rains will continue to develop over drought stricken regions of the southern Plains Sunday night into Monday as a closed low edges east out of the Four Corners region and a steady supply of moisture surges northward out of the western Gulf of Mexico. Although these areas need the precipitation...there will also be a threat for flash flooding and severe thunderstorms. A cold front will trigger showers and thunderstorms while it pushes through the Upper Midwest Sunday night and then presses south and east through the Great Lakes region Monday into Tuesday. Activity should be mostly scattered...but storms will be developing in a relatively warm and humid airmass to the south of the front...giving them the potential to become organized and produce some areas of heavy rains. A Pacific front approaching the coast will bring light to moderate precipitation into the Northwest while it moves inland Sunday evening. Precipitation should be light with this system as it crosses the Intermountain West and northern Rockies...but then some more significant showers and thunderstorms could develop once the front emerges out over the northern Plains early Tuesday. Much of the shower and thunderstorm activity along a frontal boundary stretched from the middle Mississippi Valley to the Southeast coast will begin to diminish as the boundary dissipates over the next few days. An exception to this will be over portions of the Carolinas and Georgia...where weak energy aloft will foster continued scattered convection. An upper disturbance diving down from Canada and streaking through the Northeast will keep conditions unsettled across New England for the remainder of the holiday weekend.
