Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 359 PM EDT Sun Apr 03 2016 Valid 00Z Mon Apr 04 2016 - 00Z Wed Apr 06 2016 ...A fast-moving low pressure system intensifying along an arctic front will bring late-season snow across the Great Lakes and New England through Monday... ...Unsettled weather is expected to move across the Pacific Northwest into the northern Rockies Monday and Tuesday... Following the departure of a rapidly intensifying storm which brought a quick round of snow across New England and high winds down into the Mid-Atlantic, another fast-moving low pressure system is developing along an arctic front in the Upper Midwest. This low is expected to track eastward through the lower Great Lakes tonight and quickly moves out to sea just off the southern New England coast Monday night. North of the storm track, a narrow band of snow is forecast to spread eastward from the central Great Lakes tonight, over upstate New York Monday morning and into central New England for much of the day on Monday. Near the storm track, precipitation is expected to begin as snow, then change over to rain as the storm center passes, and finally change back to snow before it ends. Arctic air will surge back into much of the eastern U.S. on Tuesday behind the departing storm. Out West, the next cold front from the Pacific is forecast to move into the Pacific Northwest on Monday with rain across much of the region except the higher elevations of the Cascades. Precipitation is forecast to change to snow as it moves into the central/northern Rockies by Tuesday morning. Farther east, precipitation should begin as snow in the upper Midwest Tuesday morning before changing over to rain Tuesday afternoon as a complex low pressure system in the northern and central Plains draws milder air northward. Meanwhile, mostly dry and warm weather is expected to persist from the South and into the Desert Southwest through Tuesday. Kong Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_wbg.php
