FIRE WEATHER PLANNING FORECAST
NATIONAL WEATHER SERVICE RENO NV
1244 PM PDT TUE JUL 28 2026
DISCUSSION
DRY AND BREEZY CONDITIONS WILL PRODUCE AREAS OF ELEVATED FIRE
WEATHER CONCERNS EACH AFTERNOON THIS WEEK. A WARMING AND DRYING TREND
WILL RESULT IN ABOVE AVERAGE TEMPERATURES THURSDAY ONWARD. VERY LOW
DAYTIME RH AND POOR NIGHTTIME RECOVERIES ON THE MID-SLOPES AND RIDGES
WILL BECOME MORE WIDESPREAD BY THE WEEKEND. MULTIPLE DAYS UNDER THIS
HOT, VERY DRY, AND UNSTABLE 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
