VALID 111700Z - 121200Z
..WESTERN UTAH
STRONG SOUTHWEST MID-LEVEL FLOW ATOP A WELL-MIXED BOUNDARY LAYER
WILL SUPPORT GUSTY SURFACE WINDS THIS AFTERNOON ACROSS WESTERN UTAH
AS DAYTIME HEATING PROGRESSES UNDER MOSTLY CLEAR SKIES. SUSTAINED
SOUTHWEST WINDS OF UP TO 20 MPH COMBINED WITH RELATIVE HUMIDITY
CLOSE TO 15% WILL RESULT IN ELEVATED FIRE WEATHER CONDITIONS FOR
PORTIONS OF WESTERN UTAH THIS AFTERNOON. THE OVERALL FIRE WEATHER
THREAT HAS SHIFTED SLIGHTLY NORTHEASTWARD BASED ON LATEST MODEL
GUIDANCE BUT REMAINS LARGELY ON TRACK.

..SYNOPSIS
THE UPPER-LEVEL TROUGH IN THE GREAT BASIN WILL MOVE MARGINALLY
EASTWARD TODAY. THE MID-LEVEL DRY SLOT WILL MOVE OVER WESTERN UTAH
DURING THE AFTERNOON. THOUGH THE MID-LEVEL JET WILL BE WEAKENING
THROUGH THE PERIOD, THERE SHOULD BE ENOUGH FLOW ACROSS PARTS OF THE
EASTERN GREAT BASIN TO PROMOTE AT LEAST POCKETS OF LOCALLY ELEVATED
FIRE WEATHER. WITH LOCALLY STRONGER WINDS AND DRIER SURFACE
CONDITIONS IN WESTERN UTAH, SUSTAINED ELEVATED CONDITIONS ARE MOST
LIKELY HERE. SURFACE WINDS OF 15-20 MPH AND RH OF 15-20% BY THE
AFTERNOON ARE EXPECTED.
