FIRE WEATHER
ISSUED AT 120 AM MDT SUN JUL 6 2025
UNDER THE INCREASING INFLUENCE OF HIGH PRESSURE EARLY THIS
WEEK, CONDITIONS WILL REMAIN HOT AND DRY AS TEMPERATURES SEE A
WARMING TREND WITH LIGHTER WINDS AND MOSTLY CLEAR SKIES. THE
WARMEST TEMPERATURES ARE EXPECTED MONDAY THROUGH WEDNESDAY, WITH
HIGHS REACHING THE UPPER 80S TO UPPER 90S IN THE VALLEYS. GIVEN
A VERY DRY AIRMASS IN PLACE, AFTERNOON HUMIDITIES WILL DROP TO
THE TEENS/20S EACH AFTERNOON, DROPPING EVEN FURTHER FOR TUESDAY
AND WEDNESDAY TO THE SINGLE DIGITS AND TEENS. INCREASED FIRE
WEATHER CONCERNS ARE EXPECTED BEGINNING WEDNESDAY AS HIGHER
CONFIDENCE NOW SUPPORTS A PACIFIC TROUGH PASSING TO OUR N/NW
LATE TUESDAY INTO WEDNESDAY AND THURSDAY, BRINGING THE RETURN OF
BREEZY WINDS AND ISOLATED WET AND DRY SHOWERS AND THUNDERSTORMS.
DUE TO A COMBINATION OF ELEVATED WINDS AND LOW RELATIVE
HUMIDITY, NEAR CRITICAL TO CRITICAL FIRE WEATHER CONDITIONS WILL
BE POSSIBLE PARTICULARLY ON WEDNESDAY. WIND GUSTS LOOK TO PEAK
AROUND 25-40 MPH BOTH WEDNESDAY AND THURSDAY. AS THAT TROUGH
PASSES TO OUR NORTH ON THURSDAY, THAT WILL HELP BRING DOWN
TEMPERATURES AND SUPPORT A SLIGHT INCREASE IN RHS, ALBEIT STILL
SUPPORTING ELEVATED TO NEAR CRITICAL FIRE WEATHER CONDITIONS.
WITH THAT TROUGH DEPARTING EAST ON FRIDAY, ISOLATED SHOWERS AND
STORMS WILL SHIFT TO BEING ALONG THE WYOMING BORDER REGION, WITH
HOT AND DRY CONDITIONS BUILDING BACK IN FOR NEXT WEEKEND.
