Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 250 PM EST Tue Dec 29 2015 Valid 00Z Wed Dec 30 2015 - 00Z Fri Jan 01 2016 ...Flooding expected to continue across the Southeast and into the Mid-Atlantic... ...Snow for the Upper Midwest and Great Lakes... Over the next few days, the cold front that is currently moving across the Mid-Atlantic and into the Gulf Coast region be the focus for heavy rainfall. The cold front will stall later on Tuesday, and will eventually move westward as a warm front across the Southeast. With plenty of Gulf moisture on tap, more rounds of showers and thunderstorms can be expected throughout Tuesday night and into Wednesday. The front stays relatively in the same place through New Years Eve which will aid in more convection through Thursday. These thunderstorms could produce isolated heavy amounts of rain and thus could lead to flash flooding. See the WPC excessive rainfall product for more details. A low that is spinning off the Northeast coastline will push out to sea toward Nova Scotia by Tuesday night. This low, moving northeastward, will continue to push light to moderate showers across the Northeast and snow in New England. Since the low is expected to quickly exit the region, most of the precipitation will taper off by Wednesday morning. A broad upper level low centered over the High Plains will help yield a light amount of snow across the northern Plains and the Upper Great Lakes on Wednesday. By Thursday, most of the snow will be lake effect downwind of the Upper and Low Great Lakes as the upper low moves eastward over the Upper Midwest. A weak front approaching the Pacific Northwest coast will bring showers and higher elevation snow through Tuesday night. Precipitation will be confined to the coast as the front pushes south into northern California by early Wednesday morning. Light precipitation can be expected for portions of the Intermountain West on Wednesday afternoon, but for the most part these regions will stay dry.
