LONG TERM /TUESDAY NIGHT THROUGH MONDAY/
Issued at 200 PM MST Mon Dec 15 2025

Main concern is Wednesday. Strong jet will move across the region and all areas will become windy to very windy, especially from mid afternoon Wednesday into Wednesday night. At this time, this appears to be a brute force wind event as the jet moves across the region.
Strongest flow will be generally along and north of the US-50 corridor, with strongest flow at higher elevations across the central mountains and higher elevations of the Pikes Peak region.

Regarding fire weather, A Fire Weather watch has been issued for all of the plains (except northern El Paso county) and Fremont county.
Winds will be quite strong along the greater I-25 corridor region with speeds of 20 to 40 mph with gusts to 45 to 50 mph likely.
Although RH values will likely not reach to critical values (<15%)
north of highway 50, given the magnitude of the winds, it is best to include areas north of US50 in the fire weather watch. For now we do not have northern EL Paso county in the watch, but if later forecast show lower RH values over this region, then a watch may be needed.

Cooler with less wind Thu as trough and jet pull away, before warmer and windier conditions return from Fri through the weekend, as strong westerly flow continues across the wrn U.S. A couple embedded waves will bring snow showers at times to the peaks along the Continental Divide, with some light accums possible over the central mountains Saturday, then along the entire Divide by late Sunday.
