Wind gusts between 58 mph and 64 mph were reported near Black Forest, Hoehne, Peterson AFB and Walsenburg. In addition, wind gusts between 65 mph and 74 mph were noted near the communities of Aguilar, Fountain and Wetmore. 75 mph to 84 mph wind gusts were observed near Buena Vista, Colorado City, Colorado Springs, Fountain and Manitou Springs. Finally, an impressive wind gust of 89 mph was recorded near the Air Force Academy with this event.

Area Forecast Discussion National Weather Service Pueblo CO 1036 PM MST Thu Nov 28 2019 .SHORT TERM...(This evening through Friday) Issued at 241 PM MST Thu Nov 28 2019 Winter Storm Warnings continue for the San Juan, La Garitas, and the higher peaks in the Sangre de Cristos as the strong mid-level low nears from the southwest. Winter Weather Advisories for the peaks in the Sawatch and Mosquito Ranges as well. There really are not any big changes to the forecast through Friday except for the addition of a High Wind Warning and High Wind Watch in the San Luis Valley and our southern tier counties, respectively. Will get to that shortly. Storm total snowfall in the San Juans and La Garitas will continue to be hefty. The hardest hit areas will be the south facing slopes in the San Juans where an additional 4 feet of snow may fall between now and Saturday morning. Still looking like 2-3 feet fall on Friday alone. A little less for the La Garitas. Another concern is the stronger winds with this system and the snow ratios. Given the origins of the storm system we are expecting a lower SLR, 11-14:1 during the day Friday. Once we start getting more cold in from the northwest, later on Friday, do the SLRs trend upwards, 15-18:1, so more powdery snow. Winds with this system will be quite strong, especially above 10,000 feet where gusts up to 65 MPH are possible. High Wind Warning for the San Luis Valley, basically from Alamosa south to the NM state line, in response to a stacked jet core, 700/500/250mb, pushing through the region tomorrow afternoon. The deeper mixing increases as this momentum core blasts through with maximum efficiency occuring between 20-22Z. Gusts to 60 MPH are expected tomorrow afternoon in the SLV in tandem with a few snow showers. While we believe accumulations will be on the lighter side, less than an inch, we could see a brief reduction in visibility as the wind driven snow showers blow through. The High Wind Watch is a little trickier across the plains and southern I-25 corridor. The best locations for potential high wind issues is in western Las Animas county in the lee of the mountain rotor waves. Forecast soundings do show a pretty staunch inversion around 6,000 feet developing tomorrow afternoon which may prohibit better mixing from occuring, hence our decision to go with a watch rather than a warning at this time. Locations closer to the Front Range will have a difficult time experiencing higher winds due to the proximity of the jet core which should be farther east out across the plains by late evening. Plus, the surface flow will be more southerly so it's mostly upslope dampening the momentum. So there you have it, snow in the higher terrain of the southwest, southern, and central mountains with winds the main issue in the SLV and southeast plains. .LONG TERM...(Friday night through Thursday) Issued at 241 PM MST Thu Nov 28 2019 ...Strong winds and snow continue Friday night into Saturday... Upper low ejects out across CO, intensifying across northeast CO and western NE Friday night. This initially puts southern CO under an intense 140 kt upper jet Friday evening with the potential for mixing to tap high winds aloft across southern portions of the forecast area into the early Friday evening. Winds decouple from the stronger core of winds aloft overnight...but expect mountain areas to stay quite windy with blowing snow still a concern, even as orographics becomes less favorable for the southwest mountains, and increases for the central mountains as winds shift around from the northwest. So although snowfall intensities will be decreasing into Saturday morning...have opted to extend winter weather highlights for the central mountains through the overnight hours to capture the potential for blowing snow and resultant travel impacts. Model cross sections and soundings suggest mountain wave parameters may develop across the eastern mountains Friday night through mid day Saturday as area comes under reverse shear aloft and NAM12 develops a mountain top inversion towards 12z. By this time, northwest flow will favor the Pikes Peak region (lee of the Ramparts, AFF area) for high wind potential and have opted to hoist a high wind watch for this area from 06z through 21z Saturday. 18z 4km NAMNest is hitting this area with up to 65 kt wind gusts after 06z which continues into Saturday morning...and although this model tends to run a little high with wind gusts, there are sufficient parameters in place to suggest the potential for high winds will be there. Have put up a high wind watch for Teller and El Paso counties though most likely impact areas will be east slopes of Pikes Peak and the Ramparts and the adjacent lower terrain along/west of I-25 in El Paso county. Given northwest flow is less favorable cross barrier flow for the Wets and Sangres, have not included these zones in the high wind watch. If flow aloft ends up a little more westerly, then these zones could also be at risk, but confidence is too low at this point for a watch. Otherwise...all other highlights look okay. Was somewhat concerned that central mountains advisories may need to be extended to include impacts from blowing snow through Saturday morning, but will let later shifts get a better look at timing and make further adjustments if necessary. Another axis of strong winds will be possible across the far eastern plains Saturday afternoon as the system wraps up across NE. Surface pressure gradient appears tighter just north and east of the forecast area...with most other areas coming near but staying just under high wind criteria through Saturday afternoon. System pulls away from the region Saturday night with winds decreasing and a cold night in store across the region, especially mountain valleys where lows will drop to between 0 and 10 below. Upper ridge translates in for Saturday, though lighter winds will mean less mixing which will temper highs down a few degrees across the lower elevations. Mountain areas will feel the affects of warming temperatures aloft with highs rebounding into the 20s and lower 30s. Temperatures remain mild through the remainder of the extended. Another system in northwest flow aloft glances by to the north Monday Night/Tuesday which will bring a slight cool down to eastern areas, but for the most part southern CO should remain dry. Another Pacific system approaches from the west next Thursday which could ramp snow chances back up across the mountains by late next week. -KT && .AVIATION...(For the 06Z TAFS through 06Z Friday night) Issued at 1029 PM MST Thu Nov 28 2019 KPUB and KCOS will see an increase in clouds tonight, with ceilings lowering toward morning, with the potential for some light snow, mainly after 12Z. Gusty southwest winds are expected to develop Fri evening. KALS will see ceilings lower tonight, with the potential for snow developing after about 10Z. Chances for precip will likely continue into the early evening hours. Gusty southwest winds are expected to develop by midmorning, and should increase even more in the afternoon and continue into the evening. && .PUB WATCHES/WARNINGS/ADVISORIES...

There will also be some snow over the Sangre de Cristo Mountains overnight, with a few inches of accumulation. Some light snow will also be possible over and near the Sawatch and Mosquito Mountains, and in the San Luis Valley, but little is expected in the way of accumulation in these locations. .DAYS TWO THROUGH SEVEN...Friday through Wednesday For Friday, snow will fall in the mountains. Very heavy snow is likely in the San Juan mountains, where several feet will be possible by Saturday morning. Lesser amounts will fall across the remainder of the mountains, but there will still be total amounts of 6 inches to 2 feet. It will be very windy across the region Friday and Saturday, with south to southwest winds on Friday, then becoming west to northwest on Saturday. Wind speeds are expected to be 40 to 60 mph across the mountains, and 30 to 45 mph across the plains. The strongest winds on Friday will generally occur along and south of Highway 50 over the plains, and in the San Luis Valley, where gusts of 55 to 60 mph are forecast. For Saturday, snow will decrease across the mountains, however it will be very windy over the mountains, causing blowing and drifting snow. .SPOTTER INFORMATION STATEMENT... Weather conditions that meet reporting criteria for spotters will be likely over the San Juan, La Garita, and Sangre de Cristo Mountains. 28/28
