FIRE WEATHER FORECAST FOR NORTHEAST AND NORTH CENTRAL COLORADO
NATIONAL WEATHER SERVICE DENVER/BOULDER CO
321 AM MDT SAT MAR 21 2026
...RED FLAG WARNING IN EFFECT FROM 2 PM THIS AFTERNOON TO 10 PM
MDT THIS EVENING FOR THE I-25 CORRIDOR AND NORTHERN PLAINS...
...RED FLAG WARNING IN EFFECT FROM 11 AM THIS MORNING TO 10 PM
MDT THIS EVENING FOR THE FOOTHILLS AND HIGH MOUNTAIN VALLEYS...
DISCUSSION...TODAY AND TONIGHT
RECORD-BREAKING MARCH HEAT WITH TEMPERATURES 35 TO 40 DEGREES ABOVE
NORMAL, COMBINED WITH EXCEPTIONALLY LOW HUMIDITY FALLING WELL INTO
THE SINGLE DIGITS, AND LOCALLY BREEZY WEST WINDS, WILL DRIVE CRITICAL
FIRE WEATHER CONDITIONS FOR ALMOST ALL AREAS BELOW ~9,000 FT TODAY.
THE GREATEST FIRE DANGER WILL BE FOCUSED ACROSS THE HIGH COUNTRY AND
AREAS ALONG AND WEST OF I-25, WHERE CONFIDENCE IN BREEZIER WINDS IS
HIGHEST. THESE AREAS WILL SEE SUSTAINED WINDS 15 TO 20 MPH, WITH GUSTS
25 TO 45 MPH, STRONGEST ABOVE 6,000 FT. WINDS MAY TAKE SLIGHTLY LONGER
TO SURFACE FOR THE LOWER ELEVATIONS, GENERALLY INCREASING MID-AFTERNOON,
SOMEWHAT LIMITING THE DURATION OF THE MOST CRITICAL CONDITIONS.
ALTHOUGH WIND SPEEDS WILL BE TAPERED WITH EASTWARD EXTENT INTO THE
PLAINS, NEAR-CRITICAL TO CRITICAL CONDITIONS CAN STILL BE EXPECTED
GIVEN VAPOR PRESSURE DEFICITS PUSHING CLIMATOLOGICAL MAXIMUMS. MIXING
HEIGHTS WILL ALSO BE ELEVATED, PROMOTING HEALTHY SMOKE DISPERSAL.
A DRY COLD FRONT TONIGHT WILL BRING A SHIFT TO NORTH/NORTHEAST WINDS FOR THE
FOOTHILLS EASTWARD, RESULTING IN IMPROVED HUMIDITY RECOVERIES.
LONG TERM DISCUSSION...SUNDAY THROUGH WEDNESDAY...
COOLER, THOUGH STILL ABOVE AVERAGE, TEMPERATURES ARE EXPECTED SUNDAY BEHIND
A LARGELY DRY COLD FRONT. HUMIDITY LEVELS WILL ALSO MODERATE AS A RESULT.
A WARMING TREND WILL RETURN MONDAY AND CONTINUE THROUGH WEDNESDAY OR THURSDAY,
WHEN RECORD TEMPERATURES WILL BE POSSIBLE ONCE AGAIN. A FEW LIGHT SHOWERS MAY
FORM IN THE HIGH COUNTRY MONDAY, BUT WETTING RAIN IS NOT EXPECTED. PROGRESSIVELY
DRIER AND BREEZIER CONDITIONS ARE EXPECTED THROUGH MID-WEEK, WITH INCREASING
POTENTIAL FOR CRITICAL FIRE WEATHER CONDITIONS EACH DAY, ESPECIALLY WEDNESDAY
AND THURSDAY.
...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...
