..SNAKE RIVER PLAIN
A BROAD AREA OF ELEVATED MID-LEVEL WINDS ON THE SOUTHERN PERIPHERY
OF A MID-LEVEL TROUGH ALONG WITH DAYTIME BOUNDARY LAYER MIXING WILL
SUPPORT BREEZY WINDS ACROSS THE SNAKE RIVER PLAIN THIS AFTERNOON.
ELEVATED HIGHLIGHTS WERE TRIMMED ACROSS PORTIONS OF THE MAGIC VALLEY
REGION OWING TO A NOW MARGINAL OVERLAP OF WINDS AND LOW RELATIVE
HUMIDITY BASED ON THE LATEST MODEL GUIDANCE CONSENSUS.

SOUTHWESTERN WYOMING. INCREASED MID-LEVEL FLOW COUPLED WITH LEE
TROUGHING FARTHER EAST WILL ENHANCE WESTERLY WINDS ACROSS THE AREA.
THE BREEZY WINDS COMBINED WITH DRY FUELS AND RELATIVE HUMIDITY
DROPPING INTO THE 15-20 PERCENT RANGE WILL PROMOTE ELEVATED FIRE
WEATHER CONDITIONS THIS AFTERNOON.

SUBTLE MID-LEVEL TROUGHING ON THE NORTHERN PERIPHERY OF THE SUB
TROPICAL RIDGE WILL CONTINUE OVER THE NORTHERN ROCKIES AND NORTHWEST

PARTS OF THE INTERMOUNTAIN WEST, SUPPORTING DRY DOWNSLOPE FLOW AHEAD

CONDITIONS, CONDUCIVE FOR ELEVATED FIRE-WEATHER CONDITIONS.
..SNAKE RIVER PLAIN INTO WESTERN WY
INCREASING MID-LEVEL FLOW ATTENDANT TO A PASSING MID-LEVEL SHORTWAVE
TROUGH WILL OVERSPREAD A DRY AND WELL-MIXED BOUNDARY LAYER ACROSS

CENTRAL/EASTERN PORTIONS OF THE SNAKE RIVER PLAIN AND THROUGH THE
RED DESERT IN SOUTHWEST WY. WESTERLY WINDS OF 15-20 MPH, COMBINED
WITH WARM AFTERNOON TEMPERATURES AND RELATIVE HUMIDITY IN THE 15-20
