VALID 281200Z - 291200Z
..SOUTHWEST WYOMING
A SURFACE LOW IN SOUTH DAKOTA, ELEVATED MID-LEVEL FLOW AND A
WELL-MIXED BOUNDARY LAYER WILL PROMOTE SUSTAINED WEST WINDS OF
AROUND 15 MPH ACROSS SOUTHWEST WYOMING SATURDAY. THESE WINDS
COMBINED WITH RELATIVE HUMIDITY OF 15-20 PERCENT AMID DRY FUELS WILL
BRING AN ELEVATED FIRE WEATHER THREAT TO MUCH OF THE WYOMING BASIN.
..SNAKE RIVER PLAIN
A PASSING MID-LEVEL TROUGH AND ATTENDANT WIND MAXIMA ATOP A DRY AND
WELL-MIXED BOUNDARY LAYER WILL SUPPORT ELEVATED SURFACE WINDS ACROSS
THE CENTRAL/EASTERN PORTIONS OF THE SNAKE RIVER PLAIN. WESTERLY
WINDS OF 15-20 MPH AND RELATIVE HUMIDITY IN THE 15-20 PERCENT RANGE
WILL SUPPORT ELEVATED FIRE WEATHER CONDITIONS SATURDAY AFTERNOON
WHERE DRY FUELS EXIST.

..SYNOPSIS
LOW-AMPLITUDE MID-LEVEL TROUGHING OVER THE NORTHERN ROCKIES WILL
BEGIN TO SHIFT EASTWARD SATURDAY AS HIGH PRESSURE OVER THE SOUTHERN
US CONTINUES TO BUILD. A BELT OF STRONGER MID-LEVEL FLOW WILL REMAIN
IN PLACE OVER PARTS OF THE INTERMOUNTAIN WEST, SUPPORTING DRY
DOWNSLOPE FLOW AHEAD OF A WEAK COLD FRONT OVER THE NORTHWEST.
..ID INTO SOUTHWEST WY
GUSTY SURFACE WINDS THROUGH CENTRAL ID AND SOUTHWEST WY COULD
SUPPORT A FEW HOURS OF ELEVATED FIRE-WEATHER POTENTIAL SATURDAY. IN
THE WAKE OF THE DEPARTING UPPER TROUGH, CONTINUED MID-LEVEL ZONAL
FLOW WILL LINGER OVER CENTRAL ID. CONFIDENCE IS HIGHEST THAT 15-20
MPH SURFACE WINDS WILL OCCUR ACROSS PORTIONS OF THE CENTRAL AND
EASTERN SNAKE RIVER PLAIN SATURDAY AFTERNOON. COINCIDENT WITH RH
BELOW 20%, ELEVATED FIRE-WEATHER CONDITIONS ARE PROBABLE AMID FUELS
THAT CONTINUE TO DRY.
FARTHER EAST INTO WY, LESS CONFIDENCE EXISTS IN SUSTAINED SURFACE
WINDS GREATER THAN 15 MPH OCCURRING ON A WIDESPREAD BASIS THROUGH
THE DAY. HOWEVER, A VERY WARM AND DRY AIR MASS WILL REMAIN IN PLACE.
THIS COULD SUPPORT SOME LOCALIZED FIRE-WEATHER CONCERNS, ESPECIALLY
WHERE TERRAIN-AUGMENTED WINDS MAY OCCASIONALLY GUST TO 15-20 MPH.
