FIRE WEATHER FORECAST FOR NORTHEAST AND NORTH CENTRAL COLORADO
NATIONAL WEATHER SERVICE DENVER/BOULDER CO
252 AM MDT TUE JUL 21 2026
DISCUSSION...TODAY AND TONIGHT
IT WON'T BE AS HOT TODAY AS A COOL FRONT AFFECTS NORTHEAST COLORADO.
LOOK FOR AFTERNOON AND EVENING SCATTERED SHOWERS AND STORMS OVER
THE AREA WITH BETTER COVERAGE ACROSS NORTHERN AREAS OF THE HIGHER
TERRAIN AND PLAINS. SOME AREAS WILL SEE LOCALLY HEAVY RAINFALL
WITH THE STRONGER STORMS.
LONG TERM DISCUSSION...WEDNESDAY THROUGH SATURDAY...
SHOWER AND THUNDERSTORM COVERAGE WILL INCREASE WEDNESDAY AND
THURSDAY ACROSS THE ENTIRE FORECAST AREA. SCATTERED TO NUMEROUS
WETTING RAINS CAN BE EXPECTED, AND LOCALLY VERY HEAVY RAIN WILL BE
POSSIBLE EACH AFTERNOON AND EVENING. SLIGHTLY COOLER WEATHER IS
EXPECTED WEDNESDAY AND THURSDAY WITH IMPROVED HUMIDITY READINGS.
FRIDAY AND SATURDAY WILL TURN DRIER AGAIN ESPECIALLY ACROSS THE
PLAINS. TEMPERATURES WILL RESUME A WARMING TREND TO ABOVE NORMAL
READINGS.
...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...
