181 FXUS65 KPUB 222346 AFDPUB Area Forecast Discussion National Weather Service Pueblo CO 446 PM MST Fri Nov 22 2024 .KEY MESSAGES... - Dry weather continues in the short term. - Warmer high temperatures will persist through Saturday. - Strong develop along the mountains, particularly the southern Sangre de Cristo Mountains, Saturday night. - Active weather returns for the end of the weekend and much of next week. && .SHORT TERM /THROUGH SATURDAY/... Issued at 232 PM MST Fri Nov 22 2024 Today/Tonight Currently, a broad ridge remains in place with winds light and variable. As for temperatures, we`re sitting in the mid 50`s in the eastern plains and low 60`s lee of the central mountains. As a large trough of low pressure along the West Coast starts to deepen, the flow aloft will start to increase and start shifting to a more southwest direction across the Four Corners. This will likely help keep those locations along the eastern slopes of the southern mts a bit warmer tonight into Saturday morning. Tomorrow Ridge continues to move out with southwesterly winds aloft increasing. Highs will be in the mid to upper 60`s just lee of the central mountains and upper 50`s in the eastern plains. Weather wise, we`re looking at nice weather again tomorrow with some spotty high clouds. Surface winds will remain light and then start increasing Saturday evening into Sunday morning. && .LONG TERM /SATURDAY NIGHT THROUGH FRIDAY/... Issued at 232 PM MST Fri Nov 22 2024 Saturday Night: Relatively quiet weather is expected for much of south central and southeastern Colorado Saturday night, though may be a bit windy for some. Synoptically, flow will become southwesterly and start to increase in magnitude as a jet streak approaches the area. While orographic forcing will start to increase, better synoptic support, along with better moisture content, will remain further west, and given that, dry conditions are expected for the region. As alluded to though, some windy conditions will materialize overnight, mostly along the mountains, and particularly along the southern Sangre de Cristo Mountains. A mountain top inversion, along with reverse shear within the column, will force stronger winds aloft associated with the approaching jet streak to the surface immediately along the leeward side of the mountains. Most wind gusts will range between 50-60 mph, though gusts to 60-70 mph, and even slightly higher, will be possible along the southern Sangre de Cristo Mountains. Confidence in the development of 50-70 mph wind gusts, and the area of strongest wind gusts, is high (70%) given strong agreement between various model guidance. Beyond all of that, most other areas will have relatively light winds, and much of the region will have pockets of mid to high level clouds. Looking at temperatures, much of the area will remain chilly and around seasonal values. With that said though, areas prone to downsloping will remain more mild overnight. Sunday - Thursday: For the remainder of the long term period, active weather makes a return to south central and southeastern Colorado. Overall, westerly flow will develop, with a couple of embedded shortwaves drifting over the region Sunday and then again Tuesday and Wednesday. This flow pattern will increase orographic forcing over the terrain, and bring some increased synoptic support as the waves push over. In addition, this flow will allow for a couple of Pacific moisture plumes to advect over the region, especially during the Tuesday - Wednesday period. Given all of that, precipitation chances will increase for the region, though will favor the mountains given persistent orographic forcing. Precipitation may become more widespread Tuesday - Wednesday as one of the aforementioned shortwaves passes over, which could bring snow to portions of the region during peak holiday travel times. Otherwise, relatively light to breezy winds and increasing clouds are expected for south central and southeastern Colorado. As for temperatures, Sunday will be the warmest day ahead of the more unsettled flow. Then for Monday - Thursday, cooler weather returns as cold fronts drop south across the area. && .AVIATION /00Z TAFS THROUGH 00Z SUNDAY/... Issued at 439 PM MST Fri Nov 22 2024 VFR conditions are expected at COS, PUB and ALS over the next 24 hours. There will be bouts of mountain wave clouds through out the taf period, with generally light diurnal wind regimes expected over night, and south to southwest winds of 10-15 kts at the terminals aft 18Z Sat. && .PUB WATCHES/WARNINGS/ADVISORIES... None. && $$ SHORT TERM...CLOUSE LONG TERM...SIMCOE AVIATION...MW
