DAY 1 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1143 AM CDT WED OCT 01 2025
VALID 011700Z - 021200Z
..NO CRITICAL AREAS
A LACK OF SUBSTANTIAL OVERLAP OF BREEZY WINDS AND DRY CONDITIONS
WILL LIMIT THE OVERALL FIRE WEATHER THREAT ACROSS THE CONTIGUOUS
U.S. TODAY. BRIEF INSTANCES OF ELEVATED FIRE WEATHER CONDITIONS ARE
POSSIBLE ACROSS PORTIONS OF SOUTHERN NV AND UT WHERE SOUTHWEST WINDS
OF UP TO 15 MPH AND RELATIVE HUMIDITY DOWN TO 20% ALIGN, BUT
PRESENCE OF RECEPTIVE FUELS FOR WILDFIRE SPREAD ARE LARGELY ABSENT.
FUELS ARE DRIER ACROSS PORTIONS OF THE NORTHERN PLAINS AND THE HIGH
PLAINS OF MT ALTHOUGH DAYTIME RELATIVE HUMIDITY BELOW 25% WILL
REMAIN SPARSE IN COVERAGE ACROSS THE NORTHERN PLAINS, LIMITING
OVERALL FIRE WEATHER THREAT. SEE PREVIOUS FORECAST BELOW FOR FURTHER
DETAILS.

..SYNOPSIS
FIRE WEATHER CONCERNS ARE EXPECTED TO BE LIMITED FOR TODAY ACROSS
THE COUNTRY. 06Z SURFACE OBSERVATIONS SHOW A SURFACE TROUGH DRAPED
FROM EASTERN MT INTO THE CENTRAL HIGH PLAINS. THIS FEATURE IS
EXPECTED TO MIGRATE EAST THROUGH THE DAY, REACHING THE CENTRAL
DAKOTAS BY PEAK HEATING. MODEST DIURNAL HEATING/MIXING WILL SUPPORT
AN UPTICK IN WINDS THROUGH LATE AFTERNOON, BUT AN OVERALL WEAKENING
OF THE SURFACE PRESSURE GRADIENT WILL LIKELY YIELD WEAKER WINDS
COMPARED TO YESTERDAY. ADDITIONALLY, CONTINUED NORTHWARD MOISTURE
RETURN AND SCATTERED CLOUD COVER SHOULD LIMIT DIURNAL RH REDUCTIONS.
HOWEVER, ISOLATED ELEVATED CONDITIONS MAY DEVELOP ACROSS THE
NORTHERN PLAINS WHERE SUFFICIENT HEATING CAN OCCUR. FURTHER WEST,
TRANSIENT ELEVATED WIND/RH CONDITIONS MAY DEVELOP ACROSS SOUTHERN NV
AND SOUTHWEST UT WITHIN A STRENGTHENING SOUTHERLY FLOW REGIME;
HOWEVER, RECENT RAINFALL AND UNSUPPORTIVE FUEL STATUS SHOULD
MITIGATE FIRE CONCERNS.
