DAY 1 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1245 AM CDT WED SEP 10 2025
VALID 101200Z - 111200Z
..SYNOPSIS
THE UPPER-LEVEL TROUGH IN THE WEST WILL CONTINUE ITS SLOW EASTWARD
PROGRESS INTO THE GREAT BASIN. THE MID-LEVEL JET WILL INTENSIFY
WITHIN THE SOUTHERN AND EASTERN GREAT BASIN. COOLER AIR ALOFT AND
MARGINAL MID-LEVEL ASCENT WILL ALSO PROMOTE SOME CONVECTION IN
WASHINGTON.
..WASHINGTON
A POCKET OF DRIER FUELS EXISTS IN THE COLUMBIA BASIN AND NEARBY
VICINITY. RECENT LIGHTNING ACTIVITY HAS LED TO FIRE STARTS. GIVEN
THE CURRENT CONVECTION IN OREGON MOVING NORTH AND WEST AROUND THE
UPPER-LOW, SOME LIGHTNING ACTIVITY CAN BE EXPECTED EARLY THIS
MORNING. ADDITIONAL THUNDERSTORMS APPEAR POSSIBLE DURING THE
AFTERNOON AND PERHAPS AGAIN OVERNIGHT TONIGHT. HOWEVER, THOSE STORMS
MAY POSE A LESSER LIGHTNING IGNITION THREAT GIVEN INCREASING PWAT
VALUES THROUGH THE PERIOD.
..EASTERN NEVADA/WESTERN UTAH
STRONG SURFACE WINDS OF 15-25 MPH WILL OVERSPREAD PARTS OF THE GREAT
BASIN BENEATH THE MID-LEVEL JET. RH COULD FALL NEAR 10% LOCALLY, BUT
15-20% WILL BE MORE COMMON. GIVEN THE POTENTIAL FOR CRITICAL
METEOROLOGICAL CONDITIONS, ELEVATED FIRE WEATHER CONCERNS ARE
EXPECTED DESPITE THE UNFAVORABLE TO MARGINAL FUEL RECEPTIVENESS IN
THESE AREAS.
