Area forecast discussion, Dec 13, 10:40 AM MST, 4 hours 37 minutes before
Area Forecast Discussion National Weather Service Pueblo CO 1040 AM MST Mon Dec 13 2021 .SHORT TERM...(Today and tonight) Issued at 352 AM MST Mon Dec 13 2021 Key Message: - Above normal temperatures with spotty critical fire weather conditions are expected this afternoon. Currently...temperatures are highly dependent on cloud cover and elevation early this morning, with 40s along the eastern midslopes and under the mountain wave cloud cover, and low lying clear areas of the lower Arkansas River Valley in the 20s. Temperatures continue to drop across the San Luis Valley, with single digits so far early this morning. Winds are generally light over the lower elevations, with breezy conditions across the higher terrain. Today and Tonight...southern Colorado will be between upper ridging to the east and an incoming upper trough off the West Coast. This will put broad southwesterly flow across Colorado. Expect another warm afternoon across southern Colorado, with upper 50s to lower 60s across the Plains. Areas over the San Luis Valley will see highs in the 40s to near 50. Spotty, critical fire weather conditions will be possible this afternoon, mainly over the higher terrain, and down along the lee slopes of the Eastern Mountains. For tonight, embedded upper energy in the southwesterly flow will spread mid and high level cloud cover across the region. This will impact temperatures overnight, with most areas remaining in the 40s to upper 30s. The exception will be the San Luis Valley where temperatures will fall into the lower teens. Westerly flow along the mid slopes of the Eastern Mountains will also keep temperatures warmer overnight as well. No precipitation is forecast through the next 24 hours. Mozley .LONG TERM...(Tuesday through Sunday) Issued at 352 AM MST Mon Dec 13 2021 ...Strong to Damaging Winds and High Fire Danger Late Tuesday Night through Wednesday... ...Heavy Snow and Blowing Snow along the Continental Divide Tuesday Afternoon through Wednesday... Key Messages: 1) Warm and dry weather Tuesday, with breezy to windy conditions leading to enhanced fire danger and critical fire weather conditions at times on the plains. 2) A strong storm system will bring mountain snows and very windy weather to the area Tuesday night and Wednesday, creating very hazardous travel and potential for rapid fire growth. Vigorous upper trough moves onshore and into the Great Basin during the day Tuesday, with increasing sw flow across CO. Snow should break out over the San Juans by late Tue afternoon as moisture increases, then become heavy in the evening as sw flow deepens. Given potential for over a foot by late Wed, along with winds gusting 50-70 mph, have hoisted a Winter Storm Watch for higher elevations of the ern San Juans, but held off on any highlights farther north and east as La Garitas and ern slopes will be strongly shadowed initially. Farther east, lee surface trough moves toward the KS border Tue, and with mid level flow increasing to 30-40 kts, expect gusty winds and very dry boundary layer to produce increased fire danger, especially along the KS border. Kept the current Fire Weather Watch area intact for now, but it will only take a slight drop in dewpoints to reach critical conditions all the way back to I-25 Tue afternoon. Tues night/Wed, snow intensity ramps up over the San Juans as trough approaches, then snow showers spread to most of the remaining mountains and interior valleys by early Wed morning. Winds will increase rapidly overnight as well, and have started a High Wind Watch for the Sangres/Wets at 11z, as models show some 80-90 kt mt top winds by sunrise. Winds at lower elevations will respond to falling surface pressure on the plains overnight, with ern mountain slopes gusting 30-40 kts by 12z, and portions of the plains south of the Arkansas River gusting 25-35 kts after midnight. Very sharp and fast moving Bora cold front rips across the area Wed morning, as upper low lifts from the 4 corners into Nebraska during the day. Window for extreme/damaging winds will likely be immediately following the cold front, which is currently forecast to move through the San Luis Valley and ern mts 12z-15z, then eastward through the I-25 corridor and across the plains 15z-18z. Given progged 700 winds of 80 kts over the area and strong downward motion, won't be surprised to see gusts 65-75 mph widespread from the San Luis Valley eastward for a few hrs Wed morning/early afternoon, before winds slowly subside toward sunset. Have hoisted a High Wind Watch for the San Luis Valley, most of the I-25 corridor and all the sern plains starting at 12z Wed, which should be early enough to catch the expected morning high winds. Left out El Paso/Teller Counties for now, as while it will still be windy here, track of the upper low overhead keeps the strongest winds and subsidence slightly south of the area. High Fire Danger also expected on the plains as well, and have hoisted another Fire Weather Watch from I-25 eastward from mid- morning until early evening. Over the mountains, snow could be briefly heavy Wed morning, especially in the Sawatch/Mosquito Ranges, before tapering off quickly in the afternoon as upper low races eastward. Remainder of the extended forecast after Wed in general looks cooler and breezy at times, as upper trough persists over the nrn Rockies and series of waves slide quickly through the flow to the north of CO. Not much precip with this pattern, save for occasional rounds of snow showers over mainly the central mountains as each wave passes. && .AVIATION...(For the 18Z TAFS through 18Z Tuesday afternoon) Issued at 1039 AM MST Mon Dec 13 2021 VFR conditions and dry weather will continue across all of the TAF sites this period. Winds are expected to be light and diurnally driven at all sites. && .PUB WATCHES/WARNINGS/ADVISORIES... Fire Weather Watch from Wednesday morning through Wednesday afternoon for COZ228>237.

Snow will break out over the eastern San Juan mountains Tuesday evening, becoming heavy at times overnight and through the morning on Wednesday. Significant accumulations and widespread blowing snow are possible, especially over higher west facing slopes near Wolf Creek Pass. Snow will spread north and east to the central and eastern mountains early Wednesday morning, with some light to moderate accumulations possible before snowfall ends late Wednesday afternoon. Strong to damaging winds will develop over the mountains after midnight Tuesday, then spread over much of the area during the day Wednesday. Gusts as high as 80 mph will be possible over the mountains, with 60 to 70 mph winds possible at lower elevations. The window for the strongest winds looks to occur from around sunrise Wednesday morning through mid-afternoon, before winds slowly diminish by evening. These strong winds will bring high fire danger to the region for much of the day Wednesday, especially across the southeast plains where humidity will drop to very low levels by late morning. Reduced visibility in blowing dust may also occur Wednesday, especially across the southeast plains. .SPOTTER INFORMATION STATEMENT... Weather spotters will not be needed today and tonight. 88/10
