DAY 1 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0211 AM CDT THU JUL 03 2025
VALID 031200Z - 041200Z
..SYNOPSIS
A COMPACT SHORTWAVE TROUGH MOVING ACROSS NORTHERN CA WILL ACCOMPANY
40-50 KT WESTERLY FLOW ACROSS THE NORTHERN GREAT BASIN. THIS WILL
ENCOURAGE DRY DOWNSLOPE FLOW ACROSS PARTS OF WESTERN NV AND THE
NORTHERN GREAT BASIN. AT THE SAME TIME, CONTINUED MONSOON MOISTURE
WILL ALLOW SCATTERED SHOWERS AND THUNDERSTORMS OVER THE
INTERMOUNTAIN WEST WITH ISOLATED LIGHTNING.
..NORTHERN GREAT BASIN
DRY AND BREEZY CONDITIONS ARE EXPECTED TODAY AND TONIGHT IN THE LEE
OF THE SIERRA AND NORTHERN GREAT BASIN AHEAD OF THE SHORTWAVE
TROUGH. SUSTAINED 15-20 MPH SURFACE WINDS ARE EXPECTED FROM THE
WEST/SOUTHWEST THROUGH THE DAY. A DRY AND DEEP BOUNDARY LAYER WILL
ALSO SUPPORT RH BELOW 15-20%. DESPITE SOME RECENT RAINFALL, AREA
FUELS REMAIN RECEPTIVE ACROSS MUCH OF NV AND THE NORTHERN GREAT
BASIN. WIDESPREAD ELEVATED AND LOCALLY CRITICAL FIRE-WEATHER
CONDITIONS ARE LIKELY.
..DRY THUNDER
AS THE UPPER TROUGH MOVES INTO THE WEST, MONSOON MOISTURE WILL BE
SHUNTED EASTWARD COMPARED TO THE LAST SEVERAL DAYS. STILL, PWATS
AROUND 0.6-0.8 INCHES ACROSS WESTERN CO AND INTO THE NORTHERN
ROCKIES WILL BE SUFFICIENT TO SUPPORT SCATTERED SHOWERS AND
THUNDERSTORMS THIS AFTERNOON AND EVENING. FUEL RECEPTIVENESS HAS
DECREASED WITH MULTIPLE ROUNDS OF SHOWERS AND STORMS THIS WEEK.
STILL, DRIER POCKETS REMAIN AND LIGHTNING OUTSIDE OF THE HEAVIER
PRECIPITATION CORES WILL BE CAPABLE OF IGNITIONS. THIS APPEARS MOST
LIKELY OVER PARTS OF NORTHERN CO TO EASTERN ID, WHERE LESS RAINFALL
HAS BEEN OBSERVED. WILL MAINTAIN ISODRYT HIGHLIGHTS FOR OCCASIONAL
LIGHTING STRIKES WITHIN RECEPTIVE FUELS.
