521 FXUS65 KPUB 242042 AFDPUB Area Forecast Discussion National Weather Service Pueblo CO 242 PM MDT Tue Sep 24 2024 .KEY MESSAGES... - Dry and warmer on Wednesday - Upper high remains over the region with dry conditions and above normal temperatures through the week && .SHORT TERM /THROUGH WEDNESDAY/... Issued at 239 PM MDT Tue Sep 24 2024 Upper level ridge will continue to build over Colorado tonight and Wednesday, bringing clear skies and warm temperatures to the region. With clear skies/light winds/dry air in place overnight, NBM continues to run several degf too warm for min temps in most high mountain valleys, and dropped readings back toward persistence/MOS guidance. On Wednesday, with ridge overhead and warm mid-levels, expect max temps deep into the 80s on the plains, which will be well above seasonal averages but still several degf cooler than daily records. Winds at most locations Wed will stay generally less than 15 mph with ridge overhead, though a few spots near the KS border, where surface pressure gradient is tighter, could gust toward 20 mph for a few hours in the afternoon. && .LONG TERM /WEDNESDAY NIGHT THROUGH MONDAY/... Issued at 239 PM MDT Tue Sep 24 2024 Upper high remains in control of the region with the blocking pattern continuing through the end of the week. Temperatures will remain above normal with Thursday being the warmest day of the week. Readings may approach or exceed 90 across portions of the plains, and locations like KCOS and KALS could get within a couple degrees of their record highs, though look to stay just shy. A weak wave will ride overtop the ridge late week sending a weak cool front into the region. Some models (EC/Canadian) bring a modest increase in mid/high level moisture with this wave which gets caught within the upper ridge bringing the potential for repeated high based isolated afternoon and evening thunderstorms for Friday and perhaps over the weekend. However, this looks overdone and drier GFS looks the way to go. A minor cool down comes in for Friday and Saturday, though temperatures will still be above normal. Another weak wave passes by to the north Sunday night into Monday, though once again, moisture looks scant and forecast leans towards a dry scenario with continued above normal temperatures into early next week. -KT && .AVIATION /18Z TAFS THROUGH 18Z WEDNESDAY/... Issued at 1206 PM MDT Tue Sep 24 2024 VFR conditions are expected at all 3 TAF sites, KCOS,KPUB, AND KALS, for the next 24 hrs. Upper level clouds are expected to clear out by the end of today. Winds will be diurnally driven. However, do anticipate COS winds will maintain a northeasterly component until late afternoon. Do have COS becoming light southerly early this evening, but could easily see a period of light and variable winds during that time period before they turn northerly once again. && .PUB WATCHES/WARNINGS/ADVISORIES... None. && $$ SHORT TERM...PETERSEN LONG TERM...KT AVIATION...AC/SR
