Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 248 PM EDT Sat Nov 05 2016 Valid 00Z Sun Nov 06 2016 - 00Z Tue Nov 08 2016 ...Heavy rain possible across portions of the southern plains... ...Unseasonably warm temperatures expected to continue Sunday and Monday across the northern plains and Upper Midwest... ...Drier conditions expected by Sunday for much of the Pacific Northwest... Moist flow off the Gulf of Mexico along with a relatively slow-moving upper-level trough will keep areas of showers and thunderstorms possible across portions of the southern plains through Sunday. Heavy rainfall will be possible for some areas. By Monday, the axis of moisture will move a bit east, with scattered to numerous showers and thunderstorms possible from the western Gulf Coast states to portions of the lower Mississippi valley. The lack of any significant cold air across the contiguous U.S. will continue through the next couple days. Afternoon high temperatures are expected to be 15 to 25 degrees above average across much of the northern plains and Upper Midwest both Sunday and Monday. A relatively weak cold front will move from the Rockies into the plains Sunday night into Monday. This front, of Pacific origin, will not have any appreciable cooler air behind it, however. Rain will persist across the Pacific Northwest into tonight before gradually tapering off on Sunday as the frontal system moves into the interior West. Drier conditions will prevail across the Pacific Northwest on Sunday, with only a few lingering rain and snow showers near the coast and in the Cascades. Farther inland, the frontal boundary will bring areas of valley rain and mountain snow showers to the northern Intermountain region and northern Rockies on Sunday.
