Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 302 PM EST Thu Nov 05 2015 Valid 00Z Fri Nov 06 2015 - 00Z Sun Nov 08 2015 ...Severe thunderstorms possible this evening for portions of the Southern Plains and Lower Mississippi Valley... ...Flash flooding possible across portions of the Southern Plains tonight, moving into the Lower Mississippi Valley by Friday and Saturday... ...Light to moderate snow showers possible for portions of the Rockies and High Plains on Friday... Heavy rain and strong thunderstorms developing ahead of a system moving across the central U.S. this afternoon will continue to push slowly through the southern Plains and into the lower/middle Mississippi Valley this evening. Some of these storms will be capable of producing severe weather and heavy rainfall with flash flooding. Heavy rainfall and scattered thunderstorms will continue to accompany the front on Friday and into Saturday as it moves across the lower/middle Mississippi Valley and into the Southeast, with only a slight risk for flash flooding expected. Over the next few days, as much as 1 to 4 inches of rainfall could be possible, especially across eastern Texas and parts of the deep South. The northern portion of this system should be faster moving across the upper Midwest and Ohio Valley tonight into Friday, reaching the Northeast by late Friday/early Saturday. Scattered light to moderate rain showers, with embedded thunderstorms, are expected to accompany this system as it moves across the Midwest and into the Northeast, with some mixed precipitation possible on the backside of the system across the Upper Great Lakes. Behind this system, a second system drops into the northern/central Rockies which should allow for some more accumulating snow on Friday. This system is much weaker so only about 2 to 6 inches of snow is expected, and should be confined to the highest elevations of the northern and central Rockies. With enough cold air in place, scattered snow showers should not be ruled out for parts of the northern High Plains as well, with little to no accumulation expected. The snow should come to an end by the weekend as higher pressure filters into the region, but temperatures are expected to be chilly; about 5 to 10 degrees below normal for this time of the year. Farther east across the southern High Plains and points east, scattered rain showers are expected. Santorelli Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_wbg.php
