Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 156 PM EST Thu Nov 7 2019 Valid 00Z Fri Nov 8 2019 - 00Z Sun Nov 10 2019 ...Below normal temperatures for much of the nation and snow for the Great Lakes and interior Northeast... The general upper level pattern over the continental U.S. through the end of the week and into the weekend will be featured with an upper level ridge situated over the West Coast and a broad upper level trough east of the Rockies. This will support the passage of a strong cold front that will reach the Gulf Coast and East Coast by Thursday night, with anomalously cold temperatures for early November behind the front across the Plains and extending to the East Coast to close out the week. Readings could be 15 to perhaps 25 degrees below normal for some areas, which may be enough to set some record low temperatures. A broad swath of light to moderate rainfall can be expected along and just behind the cold front from Texas to the Mid-Atlantic region Thursday afternoon and into Thursday night. The heaviest rainfall is likely across parts of southern Texas as the front intercepts a plume of deeper moisture from the western Gulf of Mexico. Rain is forecast to change to snow across interior portions of New York and northern New England before ending Friday morning. Several inches of snow accumulation is possible across the higher elevations. Elsewhere across the continental U.S., dry conditions are forecast across most of the western U.S. and extending eastward to the Midwest states. Lake effect snow showers are anticipated across much of Michigan by the end of the week as the Canadian airmass advects much colder air over the warmer waters of the Great Lakes. Winter storm warnings are in effect for portions of the Upper Peninsula of Michigan. Hamrick/Mullinax Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php
