...FIRE WEATHER WATCH IN EFFECT FROM FRIDAY AFTERNOON THROUGH
LATE SATURDAY NIGHT...
DISCUSSION
MOISTURE AND INSTABILITY WILL INCREASE OVER UTAH
FROM THE SOUTH TODAY, WITH THE BULK OF THIS MOISTURE REACHING THE
FIRE DURING THE LATE MORNING AND EARLY AFTERNOON. FOR THE FIRE
SPECIFICALLY, THINK THE BEST COVERAGE OF SHOWERS AND THUNDERSTORMS
WILL BE DURING THE EARLY AFTERNOON. THE MAIN THREAT FROM ANY
STORMS THAT DEVELOP WILL BE GUSTY AND ERRATIC WINDS, WITH A
RELATIVELY SMALL CHANCE OF WETTING RAINS GIVEN HOW DRY THE AIRMASS
HAS BEEN RECENTLY, PARTICULARLY AT THE LOWER LEVELS. DRIER AIR
WILL MOVE INTO THE STATE FROM THE WEST ON THURSDAY, BUT THERE IS A
LOW CHANCE OF A FEW SHOWERS AND THUNDERSTORMS DEVELOPING IN THE
VICINITY OF THE FIRE DURING THE AFTERNOON. BY FRIDAY, THE AIRMASS
WILL HAVE DRIED OUT, RESULTING IN MINIMUM RELATIVE HUMIDITY
VALUES BACK IN THE UPPER SINGLE DIGITS. ADDITIONALLY, SOUTHWEST
WINDS WILL BECOME STRONG AHEAD OF AN APPROACHING COLD FRONT, WITH
A HIGH CHANCE OF GUSTS IN EXCESS OF 40 MPH. WITH THESE STRONG,
GUSTY WINDS CONTINUING INTO SATURDAY, FIRE DANGER WILL BE
EXTREMELY HIGH FOR BOTH DAYS AND A FIRE WEATHER WATCH HAS BEEN
ISSUED. THE PASSAGE OF THE FRONT ON SUNDAY WILL BRING MUCH COOLER
TEMPERATURES, A DECREASE IN WINDS, AND A MODEST INCREASE IN
RELATIVE HUMIDITY VALUES.
