(today through Saturday) Issued at 329 AM CST Thu Dec 8 2016 Arctic high pressure continues to build southeast across the area this morning with a modest surface gradient keeping winds around 10-15kts with gusts still in the 20-25kt range. As a result, early morning wind chills are generally in the -5 to -10 range. A few low clouds continue to drift along and east of the Missouri River and a few flurries were reported under these but should continue to drift east as dry high pressure continues to build overhead. The high pressure ridge will extend over the CWA by 12Z Friday with overnight lows tonight close to zero in many areas. Despite increasing return flow Friday, the day will still be dry and cold as southerly winds increase. Wind chill values through the day will likely be around 10-15 with highs in the low 20s. Warm air advection moves into the region ahead of the next upper shortwave trough. High temperatures should be able to warm into the lower to mid 30s for Saturday with bare ground in all areas. The next piece of shortwave energy is forecast to move into the Plains Saturday with strong isentropic lift centered over much of South Dakota and northeastern Nebraska. Accumulating snow looks quite possible across our northern tier of counties Saturday into Saturday night with QPF values around a tenth of an inch along the SD/NE border. .LONG TERM...(Saturday night through Wednesday) Issued at 329 AM CST Thu Dec 8 2016 A stronger piece of shortwave energy will slide east across the area Sunday with a brief period of strong isentropic lift over the entire CWA. Accumulating snowfall is possible in association with this forcing as QPF values are forecast around two tenths of an inch. Yet another shortwave moves toward the area Tuesday along with another persistent cold surge. GFS would give the area accumulating snow Monday night into Tuesday. The EC is beginning to hint at this as well so will continue to monitor this time period closely. Overall have trended lower with temperatures in the extended.
