FIRE WEATHER PLANNING FORECAST
NATIONAL WEATHER SERVICE RENO NV
102 AM PDT TUE JUL 28 2026
DISCUSSION
DRY AND BREEZY CONDITIONS WILL PRODUCE BRIEF ELEVATED FIRE CONCERNS
EACH AFTERNOON THIS WEEK. A WARMING AND DRYING TREND WILL RESULT IN
90 DEGREE AND TRIPLE DIGIT HEAT FROM THURSDAY ONWARD. VERY LOW DAYTIME
RH AND POOR NIGHTTIME RECOVERIES BECOME MORE WIDESPREAD BY THE WEEKEND.
MULTIPLE DAYS UNDER THIS HOT AND VERY DRY AIRMASS WILL ALLOW FURTHER
DRYING OF VEGETATION, AND INCREASE THE POTENTIAL FOR HEAT IMPACTS TO
FIRE SUPPRESSION PERSONNEL AND DEEPER VERTICAL PLUME GROWTH.
NOTE: THUNDERSTORMS IMPLY GUSTY AND ERRATIC WINDS.
NOTE: MIXING HEIGHTS ARE IN FEET ABOVE GROUND LEVEL OF THE VALLEY FLOORS.
NOTE: PLEASE SEE OPERATING PLAN FOR DETAILED ZONE DESCRIPTIONS
