Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 446 AM EDT Mon Mar 10 2014 Valid 12Z Mon Mar 10 2014 - 12Z Wed Mar 12 2014 ...Active weather across the Northwest will shift out into the Great Plains... ...Showers and thunderstorms expected to move across the western and central Gulf Coast states... ...A quick moving system will bring another round of light snows to the Northeast... Active weather will continue to accompany a cold front dropping southeastward out of the northwestern corner of the Country on Monday. Another day of widespread shower activity is expected across much of the Northwest and Intermountain West; However, the main focus for precipitation will be across the Northern Rockies and adjacent High Plains...where increasing winds surrounding a deepening surface low along the boundary will force moderate to heavy upslope snows. The cold front and deepening surface cyclone will press farther south and east through much of the Nation's midsection on Tuesday and is expected to reach the eastern third of the Country by Wednesday morning. A wide axis of precipitation should develop to the north of the sinking boundary...which will spread eastward through the Great Plains and eventually Ohio Valley. Falling temperatures behind the front will allow for snow within the northern edge of the precipitation shield. Low level southerly flow ahead of a piece of southern stream energy ejecting out of Mexico will draw increasing amounts of moisture out of the Gulf. The abundant moisture should fuel an organized area of showers and thunderstorms across the western and central Gulf Coast states as the energy steadily tracks eastward early this week. Light snow showers will be possible with another weak system racing from the Upper Great Lakes to the Northeast Monday night into Tuesday. A lack of moisture and the quick progression of the system will keep any snowfall accumulations to a minimum. Gerhardt Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_wbg.php
