Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 342 AM EST Sun Nov 22 2015 Valid 12Z Sun Nov 22 2015 - 12Z Tue Nov 24 2015 ***Unsettled weather returning to the western U.S.*** ***Turning colder for the eastern U.S. behind cold front*** A return to a more active weather pattern can be expected for the West Coast and the Intermountain West for the beginning of the week. A strong cold front and pronounced upper level trough will bring noticeably colder temperatures to the Pacific Northwest and northern California by Tuesday morning, and snow levels will drop significantly with widespread accumulating snow for the mountain ranges. Strong winds can also be expected near the Coast as the pressure gradient increases. After the first significant snowstorm of the season for parts of the Upper Midwest and Great Lakes, conditions are forecast to be less active with just some patchy areas of lake effect snow remaining. The cold front should exit the East coast on Sunday, ushering in an even colder airmass for the beginning of the week. Temperatures across the eastern half of the country by Monday could be as much as 10 to 20 degrees below normal. Hamrick Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_wbg.php
