Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 331 PM EST Mon Nov 11 2013 Valid 00Z Tue Nov 12 2013 - 00Z Thu Nov 14 2013 ***Coldest air of the season arriving to much of the U.S.*** ***Flurries and snow showers possible behind cold front*** ***Relatively quiet weather pattern overall*** An arctic cold front is bringing the coldest weather thus far of the fall season to much of the northern and eastern parts of the country. This strong front will progress steadily towards the East Coast and Gulf Coast through Tuesday, before heading well offshore by Wednesday. An impressive surface high pressure ridge will settle in behind the front, along with January-like temperatures. Overnight lows are expected to fall into the single digits and teens from the Great Plains to the Upper Midwest, and 20s from Texas to the Mid-Atlantic states. Daytime highs will also be cold with highs 10 to 20 degrees below normal. Behind the cold front, there will likely be a band of mainly light precipitation and cloud cover. Light rain may transition to a rain/snow mix or even to light snow on Tuesday from Tennessee and Kentucky to the Mid-Atlantic states, including the southern Appalachians. Some minor accumulations are possible above 1000 feet elevation. Elsewhere across the continental U.S., a weakening storm system over the eastern Pacific Ocean is expected to bring periods of rain and higher elevation snow for the Pacific Northwest. A few rain and snow showers will also be possible over the northern Rockies. A few showers and isolated storms are also possible for South Florida. Dry conditions are expected for most of the Inter-Mountain West and into the Plains states. D. Hamrick Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_wbg.php
