FIRE WEATHER FORECAST FOR NORTHEAST AND NORTH CENTRAL COLORADO
NATIONAL WEATHER SERVICE DENVER/BOULDER CO
314 PM MDT MON SEP 8 2025
DISCUSSION...TONIGHT AND TUESDAY
WARM AND DRY CONDITIONS WILL
CONTINUE INTO TUESDAY, WITH ABOVE NORMAL TEMPERATURES LIKELY.
RELATIVE HUMIDITY VALUES SHOULD STAY IN THE 20-30 PERCENT RANGE
WITH LIGHT WINDS. ISOLATED TO SCATTERED HIGH BASED CONVECTION IS
EXPECTED AGAIN, MAINLY ACROSS THE HIGHER ELEVATIONS. ANY SHOWERS
OR STORMS WOULD PRODUCE MORE WIND THAN RAIN, WITH VERY LOW CHANCES
OF WETTING RAINFALL.
LONG TERM DISCUSSION...TUESDAY NIGHT THROUGH SATURDAY...A FAIRLY
ACTIVE PATTERN IS EXPECTED UNDER BROAD SOUTHWESTERLY FLOW ALOFT.
A GRADUAL INCREASE IN MOISTURE WILL LEAD TO BETTER CHANCES OF
PRECIPITATION TOWARDS THE END OF THE WEEK, ESPECIALLY OVER THE
HIGHER TERRAIN. THOUGH WINDS WILL INCREASE A BIT, WINDS AND
HUMIDITY ARE NOT EXPECTED TO APPROACH CRITICAL THRESHOLDS.
SLIGHTLY COOLER WEATHER IS ANTICIPATED BY THE WEEKEND.
...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...
