Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 400 PM EST Wed Feb 05 2014 Valid 00Z Thu Feb 06 2014 - 00Z Sat Feb 08 2014 ...Snow will come to an end in the Northeast tonight as Arctic air surges down into much of the northern and eastern two-thirds of the country... ...Low pressure systems from the Pacific will bring unsettled weather into the West... A winter storm currently bringing moderate snowfall across much of the Northeast is expected to move steadily eastward this evening and will move away from the region later tonight. Behind the storm, a large Arctic high pressure system will then build southward from Canada and become the dominant weather system for the eastern two-thirds of the country through the end of this week. Temperatures will once again drop well below normal. The coldest air is expected to settle across the High Plains where temperatures of lower than 40 degrees below normal are expected through Thursday. By Friday, the center of the Arctic high should reach the Ohio Valley. A return flow from the south will begin a moderating trend across the Plains. Over the central and southern Rockies and into Oregon, areas of light snow are expected to linger as the Arctic front becomes nearly stationary. Meanwhile, a series of Pacific low pressure systems will then approach and move onshore into the West Coast on Thursday. This will bring a period of unsettled weather across California and Oregon on Thursday and Friday, and increase the coverage of snow in the Rockies on Friday. In the Deep South, moisture appears to begin pushing northward from the Gulf of Mexico on Thursday, bringing scattered light rain into the Gulf Coast. The rain may reach as far north as northern Georgia Thursday evening where snow may even mix in. By Friday, the rain should push farther east into the Atlantic but could continue near the Texas coast. Kong Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_wbg.php
