Area Forecast Discussion National Weather Service Grand Junction CO 142 PM MST Sun Feb 6 2022 .SHORT TERM...(Tonight through Monday night) Issued at 142 PM MST Sun Feb 6 2022 Its been a relatively quiet Sunday on the Western Slope as the shortwave trough that brought light snow to areas along the Divide has split from the parent wave and departed south into New Mexico. As a result, skies have cleared across much of the region as drier air infiltrates the area under northerly flow aloft. An exception is across the Divide where low to mid clouds linger. These clouds will continue to taper off this evening before dissipating overnight. However, guidance is showing patchy stratus developing across northwest Colorado as well as the Upper Gunnison River Valley after midnight. Therefore, overnight lows will once again be tricky to nail down for our usual cold pool areas as values will be directly correlated to the development of stratus. Opted to still trend temperatures a few degrees cooler than NBM, but no drastic alterations were made. Elsewhere, it'll still be a chilly night as overnight lows will sit 4 to 8 degrees below normal. However, the progression of a ridge of high pressure situated off the California coast inland tonight will allow those temperatures to moderate as 700mb temperatures climb. The west coast ridge will remain in place on Monday but another shortwave trough will ride its periphery as it drops into the Northern Rockies. This won't be of any benefit to us as heights continue to build overhead from the west with a 10 to 12 dam jump occurring at 500mb across the region. As a result, temperatures will warm by several degrees Monday afternoon, though inversions in the snow-covered valleys will hold strong with areas such as Craig and Gunnison not expected to climb above freezing. Clouds from the aforementioned shortwave digging into the Northern Rockies will begin to advect generally high clouds into our area Monday night, though overnight lows are still likely to run several degrees above normal. .LONG TERM...(Tuesday through Sunday) Issued at 142 PM MST Sun Feb 6 2022 A trough skirting across the northern CONUS boundary on Tuesday morning will just barely touch northern portions of our forecast area. At any rate, we'll remain under weakening northerly flow as the high pressure system dominating the west CONUS coast remains in place through at least the end of the week. Models indicate a couple of wiggles in the flow on Thursday and Friday night / Saturday morning. However, not only is there little moisture to work with, the dynamic lift also looks to be minimal with these events...although some disagreement in placement of best lift remains for the later system. Really, the next best chances for precipitation appear to arrive not this week, but the following week (mid-February). Daily temperatures will continue a slow but steady warming trend through the week. Saturday could become the exception to this rule, but even that depends on the path of the aformentioned disturbance late next week. By Friday, many locations will be running 5 to 10 degrees above both normal high and low temperatures. Places like Bluff will likely exceed 60 degrees and Grand Junction will approach 50 while Craig struggles to reach 40 thanks to widespread snowcover. && .AVIATION...(For the 18Z TAFS through 18Z Monday afternoon) Issued at 1015 AM MST Sun Feb 6 2022 A disturbance continues to move south across western Colorado, causing MVFR conditions at times. Current ILS conditions at KASE are expected to improve at or before 21Z. Showers will dissipate this afternoon, although stratus could linger into tonight at some sites. && .GJT WATCHES/WARNINGS/ADVISORIES... CO...None.
