FIRE WEATHER FORECAST FOR NORTHEAST AND NORTH CENTRAL COLORADO
NATIONAL WEATHER SERVICE DENVER/BOULDER CO
1210 AM MST SAT DEC 20 2025
DISCUSSION...TONIGHT AND SATURDAY
GUSTY WINDS WILL PERSIST THROUGH MUCH OF THE NIGHT WITH ONLY A
SLOW IMPROVEMENT IN HUMIDITY VALUES. THUS, NEAR CRITICAL
RED FLAG CONDITIONS WILL OCCUR INTO EARLY SATURDAY MORNING.
SATURDAY WILL BE COOLER WITH BETTER MOISTURE ACROSS THE REGION
BEHIND A WEAK COOL FRONT. HOWEVER, GUSTY WINDS AND ELEVATED FIRE
WEATHER CONDITIONS CAN STILL BE EXPECTED FROM THE BOULDER COUNTY
FOOTHILLS SOUTHWARD. ACROSS THE MOUNTAINS, SNOW IS EXPECTED TO
DEVELOP TONIGHT AND CONTINUE INTO SATURDAY WITH LIGHT TO MODERATE
ACCUMULATIONS.
LONG TERM DISCUSSION...SATURDAY NIGHT THROUGH WEDNESDAY...
SNOW WILL TAPER OFF IN THE MOUNTAINS SATURDAY NIGHT, AND WE'LL
TRANSITION BACK TO A GENERALLY WARM AND DRY PERIOD AGAIN. THE
RIDGE AXIS LOOKS TO SET UP A LITTLE FURTHER NORTH THAN THE PAST
FEW DAYS, MEANING THE CHANCE OF HIGH WIND EVENTS IS LOWER THAN THE
PAST SEVERAL DAYS. STILL, THERE MAY BE PERIODS OF ELEVATED OR
NEAR CRITICAL FIRE WEATHER CONDITIONS EAST OF THE CONTINENTAL
DIVIDE DURING PERIODS OF STRONGER WINDS.
...THUNDERSTORMS IMPLY STRONG GUSTY ERRATIC WINDS...
...ALL SURFACE WINDS ARE 20-FOOT...10-MINUTE AVERAGED WINDS...
...CWR IS CHANCE OF WETTING RAIN - 0.10 INCH OR MORE LIQUID...
...24 HR TRENDS ARE BASED ON AVERAGES OVER THE RESPECTIVE ZONE
GROUPS AND MAY NOT MATCH THE ACTUAL FORECAST VALUES
SHOWN IN THOSE GROUPS...
