NWS Denver/Boulder, CO wrote its last area forecast discussion before the first event at Mar 8, 9:01 PM MST, 1 hour 59 minutes earlier.
Area Forecast Discussion National Weather Service Denver/Boulder CO 901 PM MST Tue Mar 8 2022 .UPDATE... Issued at 855 PM MST Tue Mar 8 2022 Northern Colorado remains under a moderate northwest flow aloft with next winter storm taking aim on Colorado. Latest radar and observations showing moisture increasing in the northern mountains this evening with snow being reported at Steamboat Springs and should be seeing some light snow over the higher mountains of Larimer county. Light snow is also flirting along our northern borders with Wyoming with snow at CYS. Surface low developing over Denver this evening and will eventually deepen and drop southward later tonight which will pull in the colder air and moisture now in Wyoming. Expect moisture to deepen during the afternoon with shallow upslope flow developing. Current forecasts look to be in good shape this evening with minimal changes needed. A return to winter on Wednesday with snow and temperatures hovering around 20 degrees on the plains. && .SHORT TERM...(This evening through Wednesday) Issued at 218 PM MST Tue Mar 8 2022 Northwest flow aloft will back to the southwest by Wednesday morning as a strengthening short wave trough drops south across the Northern Rockies and Great Basin. Orographic lift over the northern mountains is expected to bring snow, mainly late tonight. Also, far northern Colorado and more so into Wyoming/Nebraska will see lift and snow from the right entrance region of a jet streak. This is a slight shift northward in the snowfall from the previous forecast. Surface pattern is muddled. Lee cyclogenesis begins near Fort Collins and Loveland this evening. This will keep southerly winds over most of northeast Colorado through tonight. Eventually a stronger surface low forms over southern Colorado and the cold front surges south across the Front Range. Latest models show the cold front pushing through the Denver area well after midnight and around 3-4am. Low clouds and possibly fog will be possible behind the front Wednesday morning. Can't rule out a little drizzle as well. Forecast soundings show the saturated layer starts off quite shallow, so don't expect much if any drizzle at this time. Airmass Wednesday will be quite cold and temperatures may not climb above 20F. Expect orographic snow to continue in the mountains Wednesday morning with light snow spreading south across eastern Colorado. Best snowfall is expected to occur during the late afternoon and evening evening (during the evening commute). Steep lapse rates between 400-600mb and low CAPE will produce some convection snow. Frontogenesis and the instability should lead to some snow bands. Northeasterly low level winds is expected enhance snowfall near and in the foothills with these areas picking up a couple extra inches. Overall, snowfall amounts were lowered 1-2 inches, this is mainly for the shorter duration of snow expected. Will issue a Winter Weather Advisory (replacing the Winter Storm Watch) for northeast Colorado including the Urban Corridor. Snowfall amounts at the lower end of criteria, but with the potential for heavier snow bands and this occurring during the evening commute decided to issue. .LONG TERM...(Wednesday night through Tuesday) Issued at 218 PM MST Tue Mar 8 2022 Wednesday night into Thursday, light to moderate snowfall will continue over the region Wednesday night, then slowly decrease from northeast to southwest across the forecast area through the day. Only weak QG ascent over northern CO in the morning, becoming neutral/weakly subsident in the afternoon. Overall timing is still on track with this system. Increasing subsidence and drying Thursday night. High temperatures on Thursday around 20 for Denver, with temperatures on Friday morning close to zero with clearing skies/snow cover and strong radiational cooling. On Friday, a strong northwesterly flow aloft over CO with the surface high over the northeast plains shifting into the Central Plains as well. More sun and a weakening arctic airmass should add up to slightly better afternoon temperatures on Friday, with highs in the low/mid 30s across the urban corridor/northeast plains. Temperature recovery will continue with highs back above normal over the weekend. An upper level ridge will build over the west, with northwest winds aloft on Saturday becoming more zonal with the passage of the ridge axis on Sunday. A weak system could clip the northeast plains Sunday night, then more ridging over the west for early next week. Stronger flow aloft will produce some gusty winds in the Front Range mountains and foothills. && .AVIATION...(For the 06Z TAFS through 06Z Wednesday night) Issued at 855 PM MST Tue Mar 8 2022 The southeast winds holding on at the terminals this evening and not expecting the south and southwest winds until 05z or so. Cold front still on track to hit terminals between 10z- 11z as winds turn northwest then a few hours lag before IFR ceilings develop and light snow in the 16-17z time frame. The snow expected to continue through Wednesday night then diminish on Thursday. At this time snowfall accumulations expected in the 2-5 inch range, with the higher amounts at BJC. && .BOU WATCHES/WARNINGS/ADVISORIES...
