DAY 1 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1230 AM CDT SAT MAY 31 2025
VALID 311200Z - 011200Z
..SYNOPSIS
AN UPPER-LEVEL TROUGH WILL MOVE INTO THE NORTHWEST WHILE THE
STAGNANT UPPER-LEVEL LOW WILL REMAIN NEAR BAJA TODAY. WHILE THE
OVERALL PATTERN WILL KEEP STRONGER WINDS AWAY FROM THE DRIEST FUELS
IN THE SOUTHWEST, SOME ELEVATED CONCERNS ARE POSSIBLE IN THE GREAT
BASIN/NORTHWEST.
..NORTHERN GREAT BASIN/NORTHWEST
WITH THE STRONGER FLOW ALOFT MOVING IN DURING THE AFTERNOON, SOME
INCREASE IN SURFACE WINDS IS EXPECTED IN THE LEE OF THE NORTHERN
SIERRA AS WELL AS IN THE COLUMBIA BASIN. RH IN NORTHWEST
NEVADA/SOUTHEAST OREGON WILL LIKELY REACH 10-15%. WIND OF 15-20 MPH.
A PERIOD OF LOCALLY CRITICAL CONDITIONS APPEARS POSSIBLE IN NEVADA
AS DOWNSLOPE WINDS MAY REACH 20-25 MPH AT LEAST BRIEFLY. FUELS ARE
ONLY APPROACHING CRITICAL SO SOME FIRE WEATHER RISK SHOULD BE
MITIGATED.
IN THE COLUMBIA BASIN, RH MAY ONLY FALL TO 20-25%. WINDS WILL
INCREASE, BUT THIS WILL PRIMARILY OCCUR TOWARDS EVENING. POTENTIAL
FOR MID/UPPER-LEVEL CLOUDS AS WELL AS SOME INCREASE IN MARINE
AIRMASS INFLUENCE EAST OF THE CASCADES SHOULD LIMIT A MORE ROBUST
FIRE WEATHER CONCERN. HOWEVER, AT LEAST SOME OVERLAP OF STRONGER
WINDS AND MARGINALLY LOWERED RH APPEARS POSSIBLE DURING THE
AFTERNOON.
..SOUTHWEST
ADDITIONAL THUNDERSTORMS ARE EXPECTED IN ARIZONA/NEW MEXICO. PW
VALUES ARE EXPECTED TO GRADUALLY INCREASE DURING THE DAY. THIS,
ALONG WITH SLOW STORM MOTIONS, SHOULD LIMIT POTENTIAL FOR LIGHTNING
IGNITIONS.
