  chances early next week.

.SHORT TERM /THROUGH FRIDAY NIGHT/...

Issued at 220 PM MDT Thu Jun 26 2025



Dry and calm conditions are expected through the short term as high 

pressure builds. Dry air has moved in after yesterday's showers and 

thunderstorms, and looks to remain in place over the coming days. As 

a result, no precipitation is in the forecast for the remainder of 

the workweek. Despite afternoon relative humidity values in the 

single digits, critical fire weather conditions are generally not 

expected as afternoon wind gusts will be weaker with the building 

high pressure. However, localized stronger gusts may allow for red 

flag conditions in spots. Temperatures will gradually warm to 5 to 

10 degrees above normal by the weekend.

.LONG TERM /SATURDAY THROUGH WEDNESDAY/...

Issued at 220 PM MDT Thu Jun 26 2025



This weekend a ridge of high pressure builds over the region causing 

temperatures to rise 5-10 degrees above normal. For the most part 

conditions will remain dry although models are hinting at the return 

of moisture as a cold front moves from the Northern Rockies out over 

the Plains. The front pushes moisture in from the north and it may 

be enough for isolated showers in the afternoon. The other pocket of 

moisture will be confined along the Front Range so that may support 

showers along the Divide. On Monday a shortwave along the California 

coast begins to move inland. This along with the high pressure will 

increase southerly flow and ultimately advect deeper moisture in the 

from the south and east. This should cause the coverage of showers 

and storms to increase across the forecast area. Models are 

struggling with how to handle the shortwave to our southwest. 

Whether this wave is progressive or stalls out, which is a common 

problem with these systems. Therefore the details uncertain, but 

with the moisture in place afternoon convection is looking more 

likely Tuesday through Thursday. The thing to also watch is the 

potential for shortwaves across the northern tier of the country as 

they can send weak fronts into the region that disrupt the moisture 

and temporarily displace it to the south. The increased moisture 

should cause a slight decrease in temperatures mid to late week.
