Area Forecast Discussion National Weather Service Denver/Boulder CO 515 PM MST Thu Feb 10 2022 .SHORT TERM...(This evening through Friday) Issued at 325 PM MST Thu Feb 10 2022 As expected, it's mild across the plains this afternoon. Temperatures today have generally hit the mid 50s to low 60s, with the warmest temperatures observed from Boulder down into the Denver metro. Even Greeley managed to make it into the upper 40s to low 50s. Temperatures should remain mild this evening with downslope winds continuing. The first forecast challenge comes late this evening and overnight as a mountain wave amplifies. Cross-barrier flow increases to about 40kt after about 9pm tonight, with a robust stable layer near mountain top. The HRRR has been advertising gusts into the 70-85mph range above timberline in the Front Range, while other CAMs are a little more muted with the high wind signal. While the confidence in near-criteria wind gusts is high (HREF mean winds near 70mph), I still don't think we'll see widespread gusts above 75mph and have held off on any highlights. Still, gusts into the 65-70mph range will cause a good amount of blowing snow across the higher elevations tonight. A few gusts will also likely make it into the wind prone areas of Boulder and Jefferson counties, where a couple of gusts above 60 mph will be possible. Downslope flow will quickly be replaced by north-northeast winds early tomorrow morning as a cold front arrives. Gradual moistening of the low and mid-levels will take place through the morning and much of the early afternoon, with cloud cover increasing through the day. High-resolution guidance has reluctantly shifted towards a wetter solution, with HREF Probability Matched Mean QPF now showing a swath of 0.1-0.25 inches of liquid from BDU to DEN and south into the Foothills/Palmer. Model soundings show shallow upslope flow... extending up to about 750-700mb or so... and coupled with synoptic scale ascent from a nearby jet, should be enough for snow to develop in the mid-afternoon hours. Temperatures are fairly marginal and the best lift is below the DGZ, but we still could see a slick afternoon commute, especially for those heading up into the Foothills/Mountains in the evening hours. The current forecast made a minor bump up to snowfall totals in the area but no highlights are planned at this point. .LONG TERM...(Friday night through Thursday) Issued at 325 PM MST Thu Feb 10 2022 We'll see drying from the north early Friday evening, with snow quickly becoming limited to areas from Denver west and south, and then fading out in those areas by midnight. There's sharp warm advection and subsidence in mid levels after midnight which should result in quick clearing, but then some clouds will develop as the zone of warm advection lowers into the 600-500 mb layer where there is some moisture by Saturday morning. The combination of these clouds and the lack of wind on the plains may restrain the warming a bit on Saturday, though areas in and near the mountains where there will be some wind may fare better. Sunday through Tuesday will be dry and warm as a flat ridge moves over. Our forecast will remain nearer the warm side of the guidance envelope with highs near 60 in Denver. We should see some shallow valley inversions redeveloping, but starting from a fairly warm place and with lots of sun, those areas will just not be as warm as everywhere else. On Tuesday there may be some weak cyclogenesis beginning somewhere in eastern Colorado, but with the next system continuing to look a little slower, it doesn't look like there will be a real cold front until at least Tuesday night. The model spread on the midweek system is not bad for this time range. There's pretty good agreement on a substantial trough passing south of us on Wednesday or Thursday. Most of the solutions currently show the strongest lift/best precipitation south of us, but this could come back either through less digging or a sharper trough that kicks the low out on a more south-to- north path. We should get a deep frontal zone with moist upslope flow which should be cold enough for snow at some point. Uncertainty about when will limit our PoPs for now, but there will likely be at least a little snow in the Wednesday-Thursday time frame. This is a good candidate for a period of moderate snow, and heavy snow is not out of the question though it's appearing that areas further south have better chances. && .AVIATION...(For the 00Z TAFS through 00Z Friday evening) Issued at 515 PM MST Thu Feb 10 2022 VFR conditions through early Friday afternoon. Moderate westerly winds have developed this afternoon with some gustiness from time to time. Winds are expected to weaken at DEN and APA later this evening and turn more towards drainage. A mountain wave will reach BJC this evening with gusty westerly winds occurring sporadically throughout the night. A cold front will arrive tomorrow morning with a shift to gusty N/NE winds. A band of mid level frontogenesis will move over the terminals around 18-19Z tomorrow which will create light snow showers. Ceilings and visibility will drop into MVFR at least and will likely drop into IFR at some point during a heavier snow band. && .BOU WATCHES/WARNINGS/ADVISORIES...

Mostly light snow accumulations but slick travel will be possible in and near the Front Range and I-25 Corridor. Winds will be gusty over the plains behind the front, but become lighter in and near the Front Range. Saturday through Tuesday will be warmer and drier. The next system may bring a chance of snow to the mountains by Tuesday night, and the rest of the area by Wednesday. .SPOTTER INFORMATION STATEMENT...
