Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 254 PM EST Tue Nov 06 2018 Valid 00Z Wed Nov 07 2018 - 00Z Fri Nov 09 2018 ...Below average temperatures for the central and north-central U.S... ...Accumulating snow expected for portions of Kansas and Nebraska Wednesday night into Thursday... ...Increasing fire weather danger for portions of northern California beginning tonight... A cold front currently moving through the eastern U.S. will be accompanied by showers and perhaps a few thunderstorms before moving into the western Atlantic by Wednesday morning with clearing in its wake. The southern portion of the front will stall across the Gulf Coast states and southern Plains through Thursday keeping these locations unsettled with scattered showers and thunderstorms. Meanwhile, a series of weak reinforcing shots of colder air will filter into the Great Plains from the north allowing for a cooling trend in high temperatures into Thursday for many locations between the Rockies and the Appalachians. High temperature departures will range between 10 to 20 degrees below early November averages on Wednesday (northern Plains) and Thursday (entire Great Plains). With colder temperatures in place, an upper level disturbance is expected to produce 3-6 inches of snow (locally higher) for the northern Rockies through Wednesday morning with accumulating snow impacting Nebraska and Kansas late Wednesday night into Thursday. The Kansas/Nebraska accumulations are only expected to be a few inches, but this will be the second or third snow storm for the central Plains since mid-October, a region which has had an early start to the winter weather season. High pressure and slightly cooler air will work its way into the Intermountain West for Wednesday into Thursday, allowing for increasing winds for sections of central to northern California. Portions of the Sacramento Valley into the San Francisco Bay are under a Red Flag Warning given an increased threat of wild fires beginning tonight and extending through the day on Wednesday given low relative humidities and gusty winds.
