ACTIVE NORTHERN STREAM REMAINS IN PLACE. HIGH PRESSURE WILL
GRADUALLY SHIFT INTO THE GREAT BASIN THURSDAY. THESE GUSTY

WEATHER CONDITIONS TO MUCH OF CENTRAL, EASTERN AND SOUTHERN UTAH
THROUGH WEDNESDAY. SEE THE FIRE WEATHER DISCUSSION FOR MORE
DETAILS.
AS A SHORTWAVE TROUGH SHIFTS EASTWARD INTO THE GREAT BASIN FRIDAY,
EXPECT GUSTY SOUTHWESTERLY WINDS TO DEVELOP ACROSS MUCH OF THE
REGION. CURRENTLY, THE THREAT OF WIND ADVISORY WINDS (GUSTS 45
MPH+) IS AROUND 30% OR SO ACROSS WEST CENTRAL AND SOUTHWEST UTAH
FRIDAY AFTERNOON INTO FRIDAY EVENING. A MAINLY DRY COLD FRONT WILL
CROSS INTO UTAH FRIDAY EVENING...WHICH MAY PROLONG THE PERIOD OF
GUSTY WINDS INTO THE FIRST PART OF FRIDAY NIGHT.
ISOLATED HIGH-BASED CONVECTION WILL BE POSSIBLE AS EARLY AS
THURSDAY ACROSS THE SOUTHERN MOUNTAINS...AND THEN ACROSS NORTHERN
UTAH IN ASSOCIATION WITH THE SHORTWAVE TROUGH FRIDAY INTO
SATURDAY. BY SATURDAY, SUFFICIENT INSTABILITY AND DEEP LAYER SHEAR
MAY EXIST ACROSS NORTHERN UTAH TO BRING A THREAT OF ORGANIZED
CONVECTION. SOMETHING TO MONITOR MOVING FORWARD.

FIRE WEATHER
A LONG DURATION OF GUSTY WINDS AND LOW HUMIDITIES
WILL IMPACT MUCH OF THE REGION THROUGH AT LEAST FRIDAY. AS THE

REGION, GUSTY WEST TO NORTHWEST FLOW WILL CONTINUE ACROSS UTAH.
THIS WILL COMBINE WITH LOW HUMIDITIES AND POOR OVERNIGHT
RECOVERIES TO BRING CRITICAL FIRE WEATHER CONDITIONS TO EASTERN
AND SOUTHERN UTAH THROUGH WEDNESDAY. BY THURSDAY, HIGH PRESSURE
WILL BRIEFLY SHIFT EASTWARD...AND WIND GUSTS WILL DECREASE. SOME
LOCATIONS MAY SEE ELEVATED TO LOCALLY CRITICAL FIRE WEATHER
CONDITIONS THURSDAY AFTERNOON AND EVENING, PARTICULARLY ACROSS THE
CENTRAL MOUNTAINS AND ADJACENT VALLEYS.

INCREASING WINDS AHEAD OF A MAINLY DRY COLD FRONT THROUGH LATE
EVENING FRIDAY NIGHT. WIND GUSTS IN EXCESS OF 35 TO 45 MPH WILL
OCCUR ACROSS WESTERN UTAH AS EARLY FRIDAY AFTERNOON. THESE WILL
COMBINE WITH HUMIDITIES NEAR 5 TO 10 PERCENT TO BRING CRITICAL
FIRE WEATHER CONDITIONS TO WESTERN UTAH FRIDAY AFTERNOON INTO LATE
FRIDAY EVENING. ADDITIONAL AREAS ACROSS SOUTHERN UTAH MAY ALSO
SEE CRITICAL FIRE WEATHER CONDITIONS...THOUGH CONFIDENCE IS LOWER
AT THIS TIME.
