DAY 2 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0143 AM CDT SUN AUG 09 2026
VALID 101200Z - 111200Z
..SYNOPSIS
ANOTHER DAY OF ELEVATED FIRE WEATHER CONDITIONS IS EXPECTED ACROSS
THE NORTHERN GREAT BASIN INTO THE CENTRAL/NORTHERN ROCKIES AS WELL
AS PORTIONS OF THE SOUTHERN HIGH PLAINS. ISOLATED DRY THUNDERSTORMS
WILL ALSO POSE A FIRE WEATHER CONCERN FOR PARTS OF THE GREAT BASIN.
..NORTHERN GREAT BASIN
AS WITH TODAY, A PERSISTENT UPPER-LEVEL RIDGE WILL MODULATE ANY
LOW-LEVEL MASS RESPONSE ACROSS THE WESTERN CONUS, RESULTING IN WEAK
GRADIENT WINDS FOR MOST LOCATIONS MONDAY AFTERNOON. HOWEVER, DEEP
MIXING AND LOCALIZED OROGRAPHIC ENHANCEMENTS WILL PROMOTE AREAS OF
15-20 MPH WINDS (GUSTING TO 20-25 MPH AT TIMES). LITTLE MOISTURE
RECOVERY IS EXPECTED ACROSS THE CENTRAL TO NORTHERN GREAT BASIN,
WHICH WILL PROMOTE ANOTHER DAY OF SINGLE DIGIT TO LOW TEEN RH
MINIMUMS BY MID-AFTERNOON. WIDESPREAD AREAS OF ELEVATED FIRE WEATHER
CONDITIONS ARE EXPECTED, BUT HOT, DRY, AND WINDY CONDITIONS MAY BE
MORE PROLONGED/WIDESPREAD IN THE LEE OF THE NORTHERN SIERRA NEVADA
IN NORTHWEST/WESTERN NV, THROUGH THE SNAKE RIVER VALLEY, AND ACROSS
EAST-CENTRAL WY IN PROXIMITY TO A WEAK SURFACE LOW.
..CA CENTRAL VALLEY
AN ONSHORE FLOW REGIME IS EXPECTED TO PERSIST INTO MONDAY. DOWNSLOPE
WESTERLY FLOW OFF THE COASTAL TERRAIN SHOULD PROMOTE 15-20 MPH WINDS
INTO WESTERN PORTIONS OF THE CENTRAL VALLEY. DRY CONDITIONS (RH
VALUES IN THE TEENS TO LOW 20S) COUPLED WITH PRECEDING DAYS OF
DRY/WINDY CONDITIONS SHOULD SUPPORT SOME FIRE WEATHER CONCERN.
..SOUTHERN HIGH PLAINS
A MODEST DEEPENING OF THE LEE TROUGH ALONG THE CENTRAL TO NORTHERN
HIGH PLAINS WILL MAINTAIN MODEST PRESSURE GRADIENT WINDS ACROSS THE
SOUTHERN AND CENTRAL PLAINS ON MONDAY. ANOTHER DAY OF AFTERNOON HIGH
TEMPERATURES IN THE 100S WILL PROMOTE VERY DRY CONDITIONS ACROSS
WESTERN OK INTO THE PANHANDLES AND SOUTHWEST KS. A COMBINATION OF
15-20 MPH GRADIENT WINDS (GUSTING TO 20-25 MPH) AND RH MINIMUMS IN
THE TEENS SHOULD SUPPORT A SWATH OF ELEVATED FIRE WEATHER
CONDITIONS.
..DRY THUNDERSTORMS
A PLUME OF MONSOONAL MOISTURE WILL CONTINUE TO SHIFT NORTHWARD OVER
THE NEXT 24-48 HOURS. WEAK ASCENT - LARGELY DRIVEN BY OROGRAPHIC
LIFT - WILL PROMOTE ISOLATED THUNDERSTORMS ACROSS MUCH OF THE GREAT
BASIN AND SOUTHWEST/FOUR CORNERS. HOWEVER, DRIER CONDITIONS ON THE
NORTHERN FRINGE OF THE RETURNING MOISTURE (CHARACTERIZED BY PWAT
VALUES OF 0.45 TO 0.75 INCHES), COUPLED WITH ANTECEDENT DRY
LOW-LEVEL CONDITIONS, SHOULD SUPPORT FAVORABLE THERMODYNAMIC
PROFILES FOR DRY THUNDERSTORMS. WITH DRY FUELS ALREADY IN PLACE
ACROSS MUCH OF THE REGION, LIGHTNING IGNITIONS WILL BE POSSIBLE.
