FIRE WEATHER FORECAST FOR NORTHEAST AND NORTH CENTRAL COLORADO
NATIONAL WEATHER SERVICE DENVER/BOULDER CO
215 PM MDT TUE MAY 12 2026
DISCUSSION...TONIGHT AND WEDNESDAY
MODERATE SOUTHERLY WINDS (SUSTAINED 15-20 MPH WITH GUSTS UP TO 35
MPH) WILL DEVELOP WEDNESDAY MAINLY ALONG AND EAST OF A LINE FROM
LIMON TO STERLING. WITH SOUTH WINDS, DEW POINTS WILL INCREASE INTO
THE UPPER 30S ACROSS THE EASTERN PLAINS. THIS MOISTURE WILL KEEP
MINIMUM RELATIVE HUMIDITY VALUES AROUND 20 PERCENT AND ABOVE.
THEREFORE, CRITICAL FIRE WEATHER CONDITIONS ARE NOT FORECAST BUT
ELEVATED CONDITIONS WILL EXIST EAST OF A LINE FROM LIMON TO
STERLING.
LONG TERM DISCUSSION...WEDNESDAY NIGHT THROUGH SUNDAY...
A WEAK COLD FRONT WILL PASS THROUGH COLORADO THURSDAY AFTERNOON
WHICH WILL DECREASE HUMIDITY. SOME GUSTS UP TO 30 MPH ARE POSSIBLE
IN THE NORTHERN FOOTHILLS AND ACROSS THE PLAINS BY THE CHEYENNE
RIDGE. THIS WILL LEAD TO ELEVATED TO POTENTIALLY CRITICAL FIRE
WEATHER CONDITIONS IN THOSE AREAS. ELEVATED FIRE WEATHER
CONDITIONS MAY EXIST IN SOUTH PARK AND ACROSS THE PALMER DIVIDE AS
WELL BUT CRITICAL FIRE WEATHER CONDITIONS ARE LESS LIKELY THERE.
ON SUNDAY, A LOW PRESSURE SYSTEM WILL DEVELOP OVER NORTHEAST
COLORADO AND DEPENDING ON WHERE THE CENTER OF THE LOW PRESSURE
SYSTEM DEVELOPS, THERE COULD BE FIRE WEATHER CONCERNS. IF THE LOW
DEVELOPS NEAR CHEYENNE, WY, STRONG SOUTHERLY WINDS WITH WARM AND
DRY CONDITIONS COULD LEAD TO CRITICAL FIRE WEATHER CONDITIONS.

...ALL SURFACE WINDS ARE 20-FOOT...10-MINUTE AVERAGED WINDS...
