Area Forecast Discussion National Weather Service Cheyenne WY 500 AM MST Fri Feb 10 2023 .SHORT TERM...(Today through Saturday night) Issued at 300 AM MST Fri Feb 10 2023 Latest surface analysis shows high pressure centered over the central Great Plains behind our last system that moved through the area as well as over the central Rockies west of the Continental Divide. This cold air mass has brought single digit temperatures to much of southeastern WY so far this morning as well as for various spots in western NE. So far the Laramie Valley has been the cold spot with the Laramie ASOS station currently sitting at 1F degree. Clear skies and weak winds should allow temperatures to drop a few degrees below zero early this morning. Latest GOES WV imagery shows an upper level ridge axis to the west that will continue to move over WY today and Saturday that will usher out this cold air with a warming trend to above normal temperatures. 700mb temps will begin to rise above 0C and reach climatological 90th percentile values for mid-February. Looking at afternoon highs in the 30s and 40s today and a few spots reaching the 50s Saturday. One limiting factor could be potential cloud cover moving overhead Saturday afternoon. The main hazard for the short term period is elevated to strong winds for the wind-prone locations of southeast WY. A High Wind Warning remains in effect through this afternoon for the Bordeaux area along I-25 between Chugwater and Wheatland. So far, gusts have reached 45 mph, however latest RAP analysis continues to show pressure falls on the leeward side of the Laramie Range. This should continue early this morning tightening mslp gradients and further enhancing gap channel flow with a sharp mountain top inversion in place. In-house guidance continues to suggest the 5-8 AM time frame for being the most likely chance for wind gusts around 60 mph with elevated gusts continuing into Friday evening. Additionally, the Arlington/Elk Mountain area has seen elevated winds gusting 40-50 mph overnight that appears to be mslp gradient driven as well. Will need to continue to monitor winds through this morning out west along I-80. .LONG TERM...(Sunday through Thursday) Issued at 300 AM MST Fri Feb 10 2023 Models in good agreement for Sunday and into early next week, with model solutions diverging by mid to late week as a northern Pacific storm system moves across the western United States bringing much colder air and snowfall. An elongated upper level trough will move across the Front Range and northern Great Plains region through Sunday night with generally cool conditions and cloudy skies. The southern energy, which is currently part of the main system at this time over the eastern Pacific Ocean, is forecast to track southeast into southern Calif and Arizona for the weekend. Models and ensembles are in good agreement with keeping this southern energy far to the south across New Mexico and the southern Plains states as it ejects eastward Monday night and early Tuesday. Kept POP low during this period. However, the next Pacific system and associated cold front will be quick to dig southeast across the Pacific NW coastline late on Monday, entering western Wyoming Monday night. Ahead of this front, a brief period of strong gusty winds are possible for mainly the wind prone areas of southeast Wyoming with gusts of 55 to 65 MPH. Period of peak 700mb subsidence is brief around 06z to 12z Tuesday morning with mean 700mb winds around 50 to 55 knots. Looks like a pretty marginal event so far, but High Wind headlines may be needed later in the weekend. Expect just breezy to locally windy conditions outside of the wind prone areas into Tuesday morning. Monday afternoon may be the warmest day of the week for most areas with highs in the 40s to low 50s possible. Attention then shifts to the Pacific storm system which will attempt to form a closed low near the four corners region on Wednesday. Will have to monitor this system closely since ensembles are showing a good chance for QPF values over a third of an inch across the I-80 corridor with lesser amounts as you head north of I-80. However, confidence is limited with any particular solution due to some deterministic model inconsistencies and relatively large ensemble spread. The GFS remains further north but shows a disorganized system as it kicks out into the High Plains later on Wednesday, while the ECMWF shows a stronger storm system that is further south, but still shows it's precip shield extending along the I-80 corridor. Canadian and ensemble means are between these two solutions as of 00z. Continued to trend POP higher, especially along the I-80 corridor and south of the lower North Platte River Valley. QPF and snow amounts are highly uncertain at this time due to model disagreement, so will not go into any details on dynamics and forcing until storm evolution and movement are resolved. High confidence that it will get much colder from Tuesday through Thursday behind the Pacific cold front as 700mb temperatures drop to around -20c by Wednesday. High temperatures on Wednesday may not get into the 20s with persistent snow through the day. Very little recovery on Thursday as CAA aloft continues. Overnight lows in the single digits above and below zero are expected Wednesday night and possibly Thursday night, but current forecast values may be conservative based on potential snow pack. Further out, 00z models are out of phase with the ECMWF showing a broad ridge of high pressure over Wyoming and Colorado while the 00z GFS wants to quickly bring in the next Canadian cold front later next week. && .AVIATION...(For the 12Z TAFS through early Saturday morning) Issued at 500 AM MST Fri Feb 10 2023 A ridge of high pressure aloft will move east across Wyoming and Nebraska today, resulting in mostly clear skies and relatively light winds for most terminals. HAZARDS/WEATHER TRENDS: VFR conditions will continue today and into tonight. South to southwest winds expected Friday through the afternoon with some occasional gusts of 25 knots or so at KRWL and possible KSNY. && .FIRE WEATHER... Issued at 300 AM MST Fri Feb 10 2023 Minimal fire weather concerns headed into the weekend. After this morning cold weather, temperatures will begin to warm to above average temperatures, especially on Saturday. This will drive afternoon RHs to near 30 percent along and east of the Laramie Range. The next chance for widespread precipitation across the region looks to arrive the middle of next week. && .CYS WATCHES/WARNINGS/ADVISORIES...
