127 PM MDT SUN AUG 24 2025
DISCUSSION
DRY CONDITIONS WITH NEAR TO SLIGHTLY COOLER THAN NORMAL TEMPS AND
SEASONABLY HIGH HUMIDITY WILL CONTINUE THROUGH MONDAY. MONSOON
MOISTURE WILL SLOWLY LIFT INTO OUR REGION, BRINGING A CHANCE OF
THUNDERSTORMS TO THE MOUNTAINS BY TUESDAY AND CONTINUING INTO
WEDNESDAY. EXPECT INCREASING CHANCES OF SHOWERS AND WET
THUNDERSTORMS ACROSS THE REGION THURSDAY AND FRIDAY. STORMS WILL
BE SLOW-MOVING AND COULD PRODUCE LOCALLY HEAVY RAINFALL. A GRADUAL
WARMING TREND THROUGH MIDWEEK WILL GIVE WAY TO COOLING AS THE
CHANCES OF RAIN INCREASE. JKL
