Area Forecast Discussion National Weather Service Goodland KS 903 PM MST Thu Dec 31 2020 .SHORT TERM...(This evening through Saturday night) Issued at 152 PM MST Thu Dec 31 2020 Other than a brief cold surge with gusty north winds on Friday, the short term period should remain dry with warmer than average temperatures across the central High Plains region. The first of a pair of upper low centers begins lifting out of the base of the upper trough over northern Mexico this afternoon. This low center continues to lift out across eastern Texas and eastern Oklahoma tonight and across far eastern Kansas and through northern Missouri on Friday as a second upper low center begins to follow a similar path along the U.S. and Mexico border region. That second low center lifts out across central Texas on Friday night and tracks further to the east across the southern Mississippi valley region late Saturday as the entire upper pattern shifts eastward across the U.S. Further to the west, a couple weaker short wave troughs move east of the central Rockies and across the central High Plains region on Friday night and Saturday night. The large surface low pressure area associated with the two large upper low centers lifts out of the western Gulf region today and across the eastern plains states into the northern Mississippi valley region during the day on Friday. Northerly surface flow on the back side of the surface low will bring slightly cooler temperatures and and area of higher pressure to the central High Plains region on Friday and Friday night. No precipitation is expected as this storm system moves off to the northeast well east of the central High Plains region. Westerly flow aloft moving over the Rockies on Saturday will help deepen a lee surface trough along the Front Range, pushing the cooler high pressure area out of the region with southwest surface flow that will usher in warmer temperatures during the day on Saturday. The surface trough is expected to move across the forecast area Saturday night in association with the upper short wave through that is also moving eastward across the region. .LONG TERM...(Sunday through Thursday) Issued at 1252 PM MST Thu Dec 31 2020 The forecast begins with a shortwave trough crossing Nebraska and Kansas as it progresses to the southeast. Northwest flow aloft will set up over the Tri-State region as a ridge moves across the Central High Plains on Sunday and Monday. Conditions are expected to be quiet and dry with high temperatures reaching the upper 40s to mid- 50s each day. Lows will dip into the 20s both nights. The forecast becomes a little more murky and not as clear cut going into Tuesday and Wednesday. Starting out the day Tuesday, the ridge will be in place over the Central High Plains with a trough off to the west. There is considerable disagreement between models as to where the trough will be placed. As the day progresses, models have the trough moving to the east. The ECMWF takes the trough across Wyoming, with a low developing over Eastern Wyoming and western South Dakota. The GFS brings the trough much further south and west, around the Four Corners area. A couple of things to keep an eye on in the coming model runs will be track of the system, moisture potential and the possibility for breezy or windy conditions Wednesday. A southern track like the GFS should keep us dry Tuesday and Wednesday. A solution closer to the ECMWF and Canadian models could potentially bring a chance for some precipitation. With the more northern track, it does not currently look like the system would be able to tap into warm, rich gulf moisture in time for us to receive much in terms of precipitation. Should the system intensify as models currently show it and the system slows down a bit, this could mean some precipitation for the area on Wednesday. Confidence at this point in time is low. Additionally, a tightening pressure gradient over the Tri-State area could result in some breezy conditions on Wednesday. Again, there is a lot of uncertainty at this point in time with this potential system. && .AVIATION...(For the 06Z TAFS through 06Z Friday night) Issued at 900 PM MST Thu Dec 31 2020 VFR conditions will rule through the TAF period, with ceilings confined to scattered cirrus AOA 12 KFT AGL. Light/variable winds will prevail overnight.. shifting to the NW at 10-15 knots late Friday morning and early Friday afternoon. Winds will weaken and become light/variable around an hour prior to sunset Friday evening. && .GLD WATCHES/WARNINGS/ADVISORIES... KS...NONE. CO...NONE.
