.SHORT TERM /THROUGH TONIGHT/... Issued at 1208 AM MDT Fri Sep 26 2025
Today, an upper trough is forecast to slide through the Northern Plains through the day. As it does so, it is forecast to help deepen the surface low pressure along the Front Range and shift it east. That being said, it is unlikely that it deepens so much that wind gusts exceed 25 mph, with the deeper low and greater concentration forecast to be in the Northern Plains. With the surface low`s positioning, the low level flow is forecast to remain from the south/southwest through the day and allow for some weak warm air advection. With it and sunny skies, high temperatures should peak closer to the mid 80s, slightly warmer than yesterday.
Tonight, the surface low should move through the area and shift winds to out of the north around 10 mph. With the winds keeping the lower level mixed and some high level cloud cover forecast to move through, low temperatures should be a bit warmer in the upper 40s and 50s. There is a chance for some transient fog along the leading edge of the wind shift as the low moves through the area.

.LONG TERM /SATURDAY THROUGH THURSDAY/... Issued at 1252 PM MDT Thu Sep 25 2025
As that upper high shifts east, the pattern becomes increasingly amplified, with strengthening diffluent south- southwesterly flow emerging across the Southwest and High Plains. The aforementioned cut-off low will get swept up by these southwesterlies aloft, and consequently a pair of disturbances will lift across the region, sparking low chances for precipitation Sunday night and again Monday night into Tuesday. Confidence in any severe weather remains low at this time, with limited moisture return being the limiting factor. A tightening pressure gradient between the surface high slowly shifting east and one/more lee cyclones developing across central- eastern CO will also favor seasonably breezy conditions Sunday through Tuesday. While the magnitude of those southerly winds each afternoon will be a function of mixing depth (itself a function of dryline placement), the National Blend of Models (NBM) suggests the highest confidence in gusts over 40 mph (60-80% chance) will be Monday west of an Oberlin to Colby to Russell Springs line. We`ll have to carefully watch the timing of any fronts to assess potential for blowing dust, as steep 0-2km lapse rates in their wake and strong top of channel winds (35-40 kt at 850mb) could promote at least some low end potential. Forecast high temperatures range from the low to mid 80s each day, though one wouldn`t be surprised if Sunday winds up a little warmer (and windier) than forecast should mixing be deeper than expected, as LREF mean brings 850mb temps into the 23-24 degC range.
As global deterministic and ensemble guidance diverges mid to late next week, confidence in the appreciable weather decreases. However, for what it`s worth, NBM yields generally sub mentionable (i.e., less than 15%) chances for precipitation Wednesday and beyond, with temperatures trending near normal in the upper 70s to mid 80s.

.AVIATION /06Z TAFS THROUGH 06Z SATURDAY/... Issued at 1104 PM MDT Thu Sep 25 2025
For KGLD & KMCK... VFR conditions remain expected through the period. There is still a less than 10% chance for fog before 14Z at either site with the south/southwesterly winds and dry air remaining the main inhibitors. Winds should remain roughly from the south through the period at 10 kts or less. The exception is between 17-22Z as a low pressure system moves near and may increase the winds closer to 15 kts.
