FXUS65 KGJT 272059 AFDGJT Area Forecast Discussion National Weather Service Grand Junction CO 259 PM MDT Mon Oct 27 2025 .KEY MESSAGES... - A cold front is bringing some snow to the northern mountains where 2 inches has already fallen. Another inch or two is possible there. The Elkheads and Flat Tops might see an inch or two. - Colder air moves in behind the front and will bring sub- freezing temperatures to much of the area. The Freeze Watches have been upgraded to Freeze Warnings. - High pressure builds in tomorrow and persists through the week keeping dry conditions in place. && .SHORT TERM /THROUGH TUESDAY/... Issued at 150 PM MDT Mon Oct 27 2025 A cold front is currently dropping down from Wyoming and is the focus for some stronger showers across the northern valleys. The front and some favorable orographics are also bringing some accumulating snow to the Park Range where about 2 inches of snow has already fallen with another inch or two possible up there...maybe a bit more, locally. The highest elevations of the Flat Tops and Elkheads will also see an inch of snow...maybe two at best. Some gusty winds of 25 to 35 mph will also accompany frontal passage. Near sunset, the front will be draped just south of the I-70 corridor and weaken as it continues to drop southward into the late evening hours. By midnight, a few, very isolated, showers may linger along northern portions of the Divide but for all intents and purposes, precip will be over. Northwesterly flow behind the front will bring much cooler temperatures to the region. Lows will drop to below freezing for most of the CWA and those valleys that have not seen a hard freeze yet have a good chance to do so tonight so the Freeze Watches have been upgraded to Freeze Warnings. Height rises after frontal passage indicates ridging building in bringing plenty of sunny skies and seasonal, if not a bit below, late October temperatures. && .LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/... Issued at 150 PM MDT Mon Oct 27 2025 Dry, quiet weather is expected until the end of the weekend thanks to upper level ridging persisting through the long term period. A trough passing to our north Wednesday into Thursday will reduce the amplitude of ridging over our area, but impacts associated with this wave are minimal. The flattening of the ridge over our CWA will allow flow to return to more northwesterly, after a very brief shift to flow with a stronger westerly component. Otherwise, minimal impacts are expected as any support from the trough will stay well to our north, and anomalously dry air remains in place until the weekend. Temperatures will gradually warm while our region is under ridging, with highs going from just below normal on Wednesday, to 5 to 10 degrees above normal by the weekend. PWATs generally remain anomalously low until the weekend. Both the ECMWF Ens and GFS Ens are suggesting that a plume of moisture will advect into the region sometime this weekend, embedded in anticyclonic flow. It is still too far out to really say much about impacts with confidence, but depending on how things play out, this could be our next chance at precipitation in the region. && .AVIATION /18Z TAFS THROUGH 18Z TUESDAY/... Issued at 1141 AM MDT Mon Oct 27 2025 A cold front continues to move across the region, which is supporting mid level cloud cover, and light rain and snow in the northern Colorado mountains. KHDN has the greatest chance for precipitation, but PROB30 has been included for KASE and KEGE for this afternoon. Strong wind gusts are expected this afternoon and into the evening as the jet moves over our area. Winds will become calm overnight, and skies will clear, with the exception of some cloud cover lingering near the northern and central terrain.&& .GJT WATCHES/WARNINGS/ADVISORIES...
