Area Forecast Discussion National Weather Service Goodland KS 1041 PM MST Sun Jan 31 2021 .UPDATE... Issued at 455 PM MST Sun Jan 31 2021 Updated forecast to include a mention of fog for late tonight to around sunrise Monday morning for the northeast part of the forecast area. Confidence is low this will occur due to dew points falling through the night as temperatures cool. If any fog does form, it will likely only be enough to cause a slight reduction in visibility. && .SHORT TERM...(This afternoon through Tuesday night) Issued at 1145 AM MST Sun Jan 31 2021 Overview: A relatively static synoptic pattern /omega block/.. characterized by an amplifying ridge over the Central US and troughing aloft along the Pacific/Atlantic coasts.. will prevail throughout the short term period. Dry conditions, benign weather, and a warming trend are expected through Tuesday -- as an upper level ridge amplifies over the Rockies and expands eastward atop the High Plains. Lingering snowpack will be the primary complicating factor with regard to high/low temperatures in this period.. mainly north and east of Goodland where (1) snow accumulations were greater, (2) pervasive cloud cover /fog/ persisted for several days thereafter, and (3) temperatures have remained at or below freezing.. until today. Expect highs ranging from 40-50F this afternoon, with temps increasing by several degrees on Monday.. and several more degrees on Tuesday, coldest E-NE and warmest W-SW. With mostly clear skies and light/variable (or calm) winds tonight, an increased potential for early morning fog will exist where robust snowpack persists (northeast of Goodland) -- with the relative best chance along and east of a line from Trenton- Oberlin-Hill City. Similar conditions are possible Mon night and Tue night (as long as snow cover persists) -- though periods of upper level cloud cover may be a complicating factor. .LONG TERM...(Wednesday through Sunday) Issued at 208 PM MST Sun Jan 31 2021 Temperatures peak on Wednesday when the region remains under an upper ridge. Through the day, southwesterly flow develops over the High Plains as the ridge progresses east and is flattened by and incoming disturbance. A more active pattern is forecast for the rest of the period, with guidance changing once again and confidence not being any better than previous days. The consensus currently shows that an upper trough will advance from the Rockies to the Plains Wednesday night, with a cold front moving across the region by Thursday morning. The disturbance sweeps through the area, generating precipitation chances Wednesday night into Thursday and tapering off Thursday night. Main precipitation type looks to be snow, but a switchover to rain could happen during the daytime hours as temperatures warm. Dry weather briefly returns on Friday as northwest flow develops on the backside of the trough. Meanwhile, a shortwave and second cold front come south from Canada, bringing a blast of cold air and additional chances for snow Friday night through Saturday. Snow chances decrease Saturday night as the wave drifts eastward. Surface high pressure moves in on Sunday behind the front, with dry and chilly conditions forecast. As alluded to above, much uncertainty remains, so stay tuned for updates. A cooling trend is expected during this timeframe, with highs falling from the 50s and low 60s on Wednesday to the 20s for Saturday and Sunday. Low temperatures follow suit, dropping from the 20s Wednesday night to the single digits above zero Saturday night. && .AVIATION...(For the 06Z TAFS through 06Z Monday night) Issued at 1040 PM MST Sun Jan 31 2021 VFR conditions forecast for the TAFs. Main focus is the light winds turning from the southwest to the south through the TAF. Low confidence of any fog occurring at KMCK through 13z due to low dew points being brought in. If any fog does occur it will not lower conditions below VFR. && .GLD WATCHES/WARNINGS/ADVISORIES... KS...NONE. CO...NONE.
