FIRE WEATHER FORECAST FOR NORTHEAST AND NORTH CENTRAL COLORADO
NATIONAL WEATHER SERVICE DENVER/BOULDER CO
154 PM MDT THU JUN 11 2026
DISCUSSION...REST OF TODAY THROUGH FRIDAY
ELEVATED TO NEAR CRITICAL FIRE WEATHER CONDITIONS ARE PRESENT
THIS AFTERNOON ACROSS MUCH OF OUR FORECAST AREA. RELATIVE
HUMIDITIES ARE IN THE SINGLE DIGITS TO UPPER 20S AND WIND GUSTS
RANGE FROM THE TEENS TO AROUND 40MPH. LUCKILY THE STRONGEST WIND
GUSTS ARE GENERALLY OVERLAPPING WITH THE HIGHER RELATIVE
HUMIDITIES IN OUR AREA, BUT WE'RE STILL LOOKING AT NEAR CRITICAL
CONDITIONS FOR AREAS BETWEEN DOWNTOWN DENVER AND STERLING.
TOMORROW, WE'RE EXPECTING ANOTHER DAY OF ELEVATED TO NEAR CRITICAL
CONDITIONS. MINIMUM RHS WILL BE IN THE SINGLE DIGITS TO LOW TEENS
FOR MUCH OF THE AREA. WIND GUSTS WILL BE AROUND 25 TO 40 MPH IN
THE MORNING IN OUR EASTERN PLAINS, HOWEVER THE STRONGER WINDS ARE
EXPECTED TO WEAKEN AND MOVE OUT OF OUR AREA BY THE MID AFTERNOON.
THIS LIMITS THE OVERLAP BETWEEN THE STRONG WINDS AND LOW RHS TO AN
HOUR OR TWO IN THE EARLY AFTERNOON IN THE EASTERN PLAINS. IN THE
MOUNTAINS, WINDS WILL BE GUSTING TO 30 TO 45MPH IN THE AFTERNOON
WITH RHS AROUND 10%. WE HAVE HELD OFF ON ISSUING A RED FLAG
WARNING HOWEVER FOR THIS AREA DUE TO REPORTS OF GREEN UP AND
HIGHER FUEL MOISTURE WHICH WILL LIMIT THE POTENTIAL FOR RAPID FIRE
SPREAD.
LONG TERM DISCUSSION...FRIDAY NIGHT THROUGH TUESDAY...
A COLD FRONT WILL MOVE THROUGH EARLY SATURDAY BRINGING COOLER
CONDITIONS AND HIGHER RHS FOR SATURDAY THROUGH MONDAY. PORTIONS OF
THE MOUNTAIN VALLEYS WILL REMAIN IN ELEVATED FIRE WEATHER
CONDITIONS DUE TO THE CONTINUED BREEZY CONDITIONS AND RHS AROUND
15%. THERE IS A LOW TO MEDIUM CHANCE FOR SOME LIGHT RAIN LATE
SATURDAY THROUGH MONDAY, BUT IT IS NOT EXPECTED TO BE WIDESPREAD.
...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...
