THIS HAZARDOUS WEATHER OUTLOOK IS FOR EASTERN UTAH AND WESTERN
COLORADO.

.DAY ONE...TODAY AND TONIGHT

GUSTY WINDS AND LOW HUMIDITY THIS AFTERNOON AHEAD OF A COLD FRONT WILL

FLAG WARNING HAS BEEN ISSUED FOR MUCH OF SOUTHWESTERN COLORADO TO
ACCOUNT FOR THIS. LOCAL WIND GUSTS TO 35 MPH ARE LIKELY.
SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS MAINLY OVER THE
NORTHERN AND CENTRAL MOUNTAINS WILL PRODUCE ONLY LIGHT
PRECIPITATION.

A FIRE WEATHER WATCH HAS BEEN ISSUED FOR THURSDAY AS DRY
CONDITIONS AND GUSTY WINDS CONTINUE. AN UPPER LEVEL TROUGH WILL
MOVE OVER THE REGION BRINGING COOLER AIR AND ANOTHER ROUND OF

THAT...WEAK RIDGING BUILDS IN BRINGING A WARM UP FOR THE WEEKEND.
THE NEXT CHANCE FOR PRECIPITATION LOOKS TO BE TUESDAY.
