DAY 1 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0159 AM CDT FRI SEP 25 2026
VALID 251200Z - 261200Z
..SYNOPSIS
WITHIN THE BASE OF A ROBUST MIDLEVEL TROUGH MOVING EASTWARD ACROSS
THE NORTHWEST, 40-50-KT MIDLEVEL WEST-SOUTHWESTERLY FLOW WILL
OVERSPREAD THE NORTHERN GREAT BASIN TODAY. DOWNSLOPE-AIDED WARMING
AND DRYING WILL PROMOTE DEEP BOUNDARY-LAYER MIXING, ALLOWING
STRONGER FLOW ALOFT TO EFFICIENTLY MIX TO THE SURFACE AHEAD OF AN
EASTWARD-MOVING COLD FRONT. AS A RESULT, A CORRIDOR OF 15-20 MPH
SUSTAINED WEST-SOUTHWESTERLY SURFACE WINDS WILL COMBINE WITH 15-20
PERCENT RH ACROSS PARTS OF NORTHERN NV, SOUTHEASTERN OR, AND
SOUTHWESTERN ID THIS AFTERNOON. GIVEN AT LEAST MODESTLY RECEPTIVE
FUELS, ELEVATED FIRE-WEATHER CONDITIONS ARE EXPECTED.
A NORTHERLY WIND SHIFT IS EXPECTED BEHIND THE COLD FRONT THIS
EVENING, THOUGH WEAKER POST-FRONTAL WIND SPEEDS SHOULD LIMIT
ADDITIONAL FIRE-WEATHER CONCERNS.
