Area Forecast Discussion National Weather Service Cheyenne WY 1113 AM MDT Sun Mar 19 2023 .SHORT TERM...(Today through Tuesday) Issued at 400 AM MDT Sun Mar 19 2023 Weak upper-level ridging over the Intermountain West and High Plains over the next few days will keep temperatures across most of the CWA near-average. High temperatures on Sunday will range from the 40s to mid 50s with sunny skies. It will also be on the breezy side as a weak shortwave within the ridge will cause both MSLP and height gradients along the west of the Laramie Range to steepen. The wind prone areas of Arlington and Bordeaux could see gusts up to 55 MPH this afternoon as flow aloft maxes out around 45 kts with decent subsidence. Could need an SPS for these areas later in the day since an occasional gust to 60 MPH cannot be ruled out with gap flow. Wind prone adjacent plains areas could see gusts up to 40 MPH. Weather gets more interesting on Monday with an incoming upper-level shortwave that's a bit more potent than the one on Sunday. Luckily, the weak ridge will hang on through the afternoon, leading to high temperatures similar to Sunday's, but with increasing clouds. Mountain snow begins during the day on Monday with moist southwesterly flow ahead of the shortwave. This is a great set-up for the Sierra Madre Range to receive a quick foot of snowfall along the highest peaks of the range. Winds turn more westerly on Tuesday as the shortwave moves off to the northeast and the CWA briefly dries out before the next storm system right at its heels. Overall, locations above 9000 feet in the Sierra Madre Range could see between 6 and 12 inches of snowfall between Monday and Tuesday afternoon which could prompt the issuance of a Winter Weather Advisory. The Snowy Range will largely be shadowed in this event so not expecting anything over 6 inches in this range. Not expecting much in the way of any snow accumulations for the plains either, though some locations could wake up on Tuesday morning to a dusting of snow. .LONG TERM...(Wednesday through Saturday) Issued at 400 AM MDT Sun Mar 19 2023 GFS and ECMWF coming into good agreement with a fairly strong shortwave moving through the CWA Wednesday. Good upper level diffluence over our western CWA Wednesday with the CWA on the left front quadrant of a strong 150kt jet moving through northern Colorado. Should have great lift with widespread precipitation forecast for most of the CWA. Will likely need a winter headline for the Sierra Madre and Snowy Ranges for Wednesday. Since it is still three days out...decided to let the dayshift take a look at the 12Z models before issuing any products. Upper shortwave trough moves through late Wednesday evening. Surface front remains over the area through Thursday morning before lifting north as a warm front Thursday afternoon. Longwave trough over the Rockies Friday with unsettled weather to continue. Next Pacific low pressure system tracks into Utah Friday afternoon. Differences in guidance as GFS has surface front over central Colorado with widespread precipitation over much of the state. ECMWF however...has the upper shortwave tracking across Wyoming...with precipitation further north across northern Wyoming. && .AVIATION...(For the 18Z TAFS through 18Z Monday afternoon) Issued at 1106 AM MDT Sun Mar 19 2023 VFR to MVFR conditions likely through the forecast period for all terminals. Shortwave trough is expected to dig across the region this afternoon into the evening hours, bringing some gusty winds and precipitation chances across the far southwestern portions of the CWA. At this time, not expecting any precipitation chances for KRWL with the arrival of this boundary. But will see precipitation chances increase after 18z tomorrow. Otherwise, expect lowering ceilings towards MVFR and increased wind speeds early tomorrow morning. && .FIRE WEATHER... Issued at 400 AM MDT Sun Mar 19 2023 Elevated fire weather conditions are possible Sunday. Relative humidities east of the Laramie Range drop into the mid teens with wind gusts up to 35 MPH. Temperatures on Sunday will also be warmer in these locations, making it into the 40s and low 50s. Conditions improve through the beginning of the work week as an upper-level disturbance brings increased moisture and the chance for both rain and snow showers. && .CYS WATCHES/WARNINGS/ADVISORIES... WY...None. NE...None. && SHORT TERM...SF LONG TERM...GCC AVIATION...MRD FIRE WEATHER...SF
