CONTINUING HOT AND DRY WEATHER:
HIGH PRESSURE CENTERED TO OUR SOUTH WILL KEEP HOT AND DRY CONDITIONS
IN THE FORECAST THROUGH THIS WEEKEND. HEAT ADVISORIES REMAIN IN
EFFECT THROUGH THIS EVENING FOR SOME OF THE DESERT VALLEY AREAS OF
EASTERN UTAH AND WESTERN COLORADO. TOMORROW DAYTIME HIGH
TEMPERATURES ARE FORECAST TO BE A BIT LOWER, BUT ONLY BY A FEW
DEGREES AT MOST. TEMPERATURES WILL CLIMB AGAIN DURING THE
LATTER HALF OF THE WORKWEEK AS HIGH PRESSURE STRENGTHENS AND
GRADUALLY BECOMES CENTERED OVER THE INTERMOUNTAIN WEST. THERE IS
A NON-ZERO CHANCE OF AFTERNOON CONVECTION OVER THE SOUTHERN
HIGH TERRAIN, BUT WITH EXCEPTIONALLY DRY AIR IN PLACE SHOWERS
AND THUNDERSTORMS ARE UNLIKELY. MODEL TRENDS SUGGEST THAT
MOISTURE COULD START MAKING ITS WAY BACK INTO OUR REGION
SOMETIME NEXT WEEK.
FIRE WEATHER CONDITIONS THROUGH THE WORKWEEK:
HIGH PRESSURE WILL GENERALLY KEEP AFTERNOON WIND GUSTS ON THE
LIGHTER SIDE, BUT A JET TO OUR NORTH/NORTHEAST AND AN INCREASED
PRESSURE GRADIENT WILL SUPPORT STRONGER AFTERNOON GUSTS,
PRIMARILY OVER AREAS OF HIGHER TERRAIN. THESE GUSTS COUPLED WITH
THE HOT AND DRY WEATHER IS CREATING CRITICAL FIRE WEATHER
CONDITIONS IN SOME AREAS. AS SUCH, RED FLAG WARNINGS REMAIN IN
EFFECT TODAY UNTIL 7 PM FOR A FEW ZONES IN WESTERN COLORADO.
TOMORROW RED FLAG WARNINGS ARE IN EFFECT FROM 1 PM TO 8 PM FOR
ZONES IN THE CENTRAL DIVIDE. FIRE WEATHER CONDITIONS LOOK TO
BECOME MORE LOCALIZED LATER THIS WEEK AS WIND GUSTS DROP BELOW
