DAY 1 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1236 AM CDT MON SEP 08 2025
VALID 081200Z - 091200Z
..NO CRITICAL AREAS
..SYNOPSIS
A BROAD UPPER-LEVEL TROUGH WILL MOVE INTO THE WEST COAST AND WESTERN
GREAT BASIN TODAY. THIS FEATURE WILL DRIVE AN INCREASE IN SURFACE
WINDS ACROSS PARTS OF THE GREAT BASIN INTO SOUTHEAST OREGON.
THUNDERSTORMS WILL ALSO BE POSSIBLE IN PARTS OF THE NORTHWEST AND
NORTHERN ROCKIES.
..GREAT BASIN
LOCALLY DRY AND BREEZY CONDITIONS ARE EXPECTED IN SOUTHERN INTO
EAST-CENTRAL NEVADA. WITH ERCS HAVING DECREASED IN THE LAST COUPLE
OF WEEKS AND ONLY A MODEST SURFACE PRESSURE GRADIENT, FIRE WEATHER
CONCERNS WILL BE RATHER LIMITED.
..NORTHWEST INTO NORTHERN ROCKIES
AREAS OF SCATTERED THUNDERSTORMS CAN BE EXPECTED AS THE TROUGH MOVES
EASTWARD DURING THE DAY. ADDITIONAL THUNDERSTORM ACTIVITY MAY ALSO
OCCUR DURING THE OVERNIGHT IN CENTRAL IDAHO. WITH THE RECENT
RAINFALL, INCREASING RH, AND A MIXED OF WET/DRY STORM MODES,
POTENTIAL FOR ADDITIONAL LIGHTNING IGNITIONS SHOULD REMAIN
LOCALIZED. PARTS OF THE NORTHERN ROCKIES HAVE OBSERVED LESS RAINFALL
OVER THE PAST WEEK. HOWEVER, FUELS ARE SOMEWHAT MARGINAL (60-70TH
PERCENTILE ERCS). ADDITIONALLY, DRY AND BREEZY CONDITIONS ARE
POSSIBLE IN SOUTHEAST OREGON. AGAIN, FUEL RECEPTIVENESS HAS
DECREASED DUE IN PART TO RECENT RAINFALL.
