Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 241 AM EST Thu Nov 28 2019 Valid 12Z Thu Nov 28 2019 - 12Z Sat Nov 30 2019 ...Strong low pressure system to create widespread snow, rain, and wind from the Intermountain West to the Great Plains for the end of the week... The weather pattern remains quite active going into the Thanksgiving holiday and into the upcoming weekend. The first storm system that produced widespread heavy snow from the Central Rockies to the Upper Great Lakes will be winding down across the Northeast U.S. as the surface low moves offshore and towards the Canadian maritimes on Thanksgiving day. Snowfall accumulations are not expected to be as great across northern New England compared to what has occurred across the mid section of the nation, with snowfall totals of 3-6 inches possible across portions of northern New Hampshire into northern Maine. In the wake of this storm moving off the New England coast on Thursday, very windy conditions are likely on Thanksgiving across much of the Northeast along with much cooler temperatures compared to midweek. The second and more impactful storm system currently over the Intermountain West remains a very large system with impacts expected across a large portion of the western and central U.S. through the end of the week. Heavy snow is likely through the end of the week from the Sierra Nevada to the central and northern Rockies. Snowfall totals across many of these regions are likely to be in the 1 to 2 foot range. By Friday, snow is forecast to develop across the northern Plains where winter storm watches are now in effect. Farther to the east, a separate area of rain will be drawn northeastward ahead of the western storm system across the southern Plains through Friday. There is a Marginal Risk for both excessive rainfall and severe thunderstorms across portions of Texas and Oklahoma. Dry weather will continue across the Southeast U.S. and Mid-Atlantic region to close out the week. Hamrick Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php
