Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 347 AM EDT Sat Apr 8 2017 Valid 12Z Sat Apr 8 2017 - 12Z Mon Apr 10 2017 ...Low pressure system tracking eastward across the Rockies and the Plains will bring a variety of weather impacts through the weekend... A strong cold front will continue to track eastward across the western U.S. and then across the central and northern Plains. This front will interact with several shortwave disturbances aloft and a strong jet stream, advecting abundant moisture inland from the Pacific Ocean. Widespread snow is expected for the central and northern Rockies, Wasatch range, and the Sierra Nevada. Winter Storm Warnings are currently in effect for the mountains of western Wyoming and also for the Sierra, and winter weather advisories for many of the other mountain ranges. In addition to the valley rain and mountain snow, strong and gusty winds are forecast with gusts in excess of 40 mph, and wind advisories are in effect from southern California to the Four Corners region. Fire weather conditions can be expected ahead of the front across eastern Arizona and much of New Mexico where very dry conditions along with gusty winds will be present. Across the eastern U.S., temperatures will begin to slowly moderate after the cold day on Friday. Saturday morning will be the coldest during the short range period, with frost advisories and freeze warnings in effect across much of the Ohio Valley and inland portions of the Mid-Atlantic. A few lingering snow showers will be possible across parts of New England on Saturday, but otherwise the eastern U.S. should enjoy a dry and mostly sunny weekend.
