DAY 1 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1146 AM CDT MON JUL 27 2026
VALID 271700Z - 281200Z
THE FORECAST REMAINS ON TRACK FOR ELEVATED FIRE WEATHER CONDITIONS
ACROSS PORTIONS OF THE NORTHWESTERN CONUS. POOR TO MARGINAL
OVERNIGHT HUMIDITY RECOVERIES AND DAYTIME HEATING WILL CONTRIBUTE TO
CRITICAL RH VALUES OF 10-15% THIS AFTERNOON AMID SOUTHWESTERLY WINDS
OF 10-15 MPH (GUSTS UP TO 25 MPH). METEOROLOGICAL CONDITIONS WILL
OVERLAP A VERY DRY, DROUGHT-STRESSED FUELSCAPE (80-95TH PERCENTILE
ERCS) WITH MULTIPLE ONGOING LARGE WILDFIRES. ANY LIGHTNING HOLDOVERS
FROM THUNDERSTORMS LAST WEEK/WEEKEND MAY ALSO EMERGE AS A RESULT OF
HOT, DRY, AND BREEZY CONDITIONS.

..SYNOPSIS
AN UPPER RIDGE WILL REMAIN IN PLACE OVER THE WESTERN CONUS TODAY,
WITH MODEST MID-LEVEL FLOW POISED TO PIVOT AROUND THE RIDGE DURING
THE AFTERNOON HOURS, WHEN A DEEP AND DRY BOUNDARY LAYER WILL
ENCOURAGE DOWNWARD MOMENTUM TRANSPORT OF THE STRONGER FLOW ALOFT.
THE MOST LIKELY LOCATION FOR BOUNDARY-LAYER MIXING AND ASSOCIATED
STRONGER SURFACE WINDS WILL BE ACROSS THE NORTHERN SIERRA INTO THE
NORTHERN ROCKIES, WHERE SOUTHWESTERLY SURFACE WINDS MAY OCCASIONALLY
EXCEED 15 MPH AMID 20 PERCENT RH AND DRY FUELS. AS SUCH, ELEVATED
HIGHLIGHTS HAVE BEEN MAINTAINED.
