FIRE WEATHER PLANNING FORECAST FOR SOUTHERN NEVADA
NORTHWEST ARIZONA AND SOUTHEAST CALIFORNIA
NATIONAL WEATHER SERVICE LAS VEGAS NV
203 AM PDT WED AUG 12 2026
DISCUSSION
TEMPERATURES CONTINUE TO COOL AND HUMIDITIES
CONTINUE TO IMPROVE AS MORE MONSOONAL MOISTURE BUILDS INTO THE
AREA. THIS INCREASE IN MOISTURE WILL ALSO CALL FOR BETTER CHANCES
FOR DAILY STORM CHANCES. AFTER SOME EARLY LIGHT SHOWERS, SOUTHERN
PORTIONS OF THE DISTRICT WILL SEE STORMS CHANCES BUILD AROUND
NOON, WITH STORM CHANCES BECOMING WIDESPREAD IN THE MID-
AFTERNOON. ISOLATED THUNDERSTORMS WILL FAVOR THE HIGHER TERRAIN
BEFORE SPREADING INTO ADJACENT VALLEYS. STORM CHANCES DECREASE
INTO THE EARLY NIGHT, BUT DON'T FULLY DISSIPATE UNTIL THE LATE
NIGHT. NO SIGNIFICANT WIND IS EXPECTED ASIDE FROM STORM-PRODUCED
WINDS. THURSDAY WILL SEE ADDITIONAL CHANCES FOR AFTERNOON STORMS
BUT WITH LESS OF A SPREAD AND CHANCES END INTO THE LATE EVENING. A
PATTERN CHANGE ON FRIDAY LOOKS TO GREATLY REDUCE THE CHANCES AND
SPREAD OF STORMS, BUT STILL OFFERS SOME CHANCES. THE PATTERN IS
EXPECTED TO CALM FOR THE WEEKEND ITSELF WITH SLIGHTLY REDUCED
HUMIDITIES AND SOME BREEZY WINDS.
NOTE: THUNDERSTORMS IMPLY GUSTY AND ERRATIC WINDS.
