AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RENO NV
1259 AM PDT MON JUN 22 2026
KEY MESSAGES
* ABOVE AVERAGE TEMPERATURES, AND WIDESPREAD MODERATE HEATRISK ARE
EXPECTED MONDAY THROUGH THURSDAY FOR WESTERN NV, WITH TYPICAL
AFTERNOON BREEZES.
* UPPER TROUGH POTENTIALLY ARRIVES BY THE END OF THE WEEK, WITH AN
INCREASE IN WINDS, LOWER TEMPERATURES AND LOW CHANCES FOR
ISOLATED SHOWERS AND THUNDERSTORMS NEAR THE OR BORDER.
DISCUSSION
* HIGH PRESSURE CENTERED OVER THE DESERT SOUTHWEST WILL GRADUALLY
EXPAND INTO THE FORECAST AREA THROUGH TUESDAY. THIS WILL ALLOW
FOR A WARMING TREND, WITH TEMPERATURES RETURNING TO THE MID TO
UPPER 90S FOR MUCH OF WESTERN NV AND EASTERN LASSEN COUNTY. WE
COULD EVEN SEE NEAR THE CENTURY MARK FOR THE CHALFANT VALLEY AND
ISOLATED VALLEYS IN THE NV BASIN AND RANGE. HIGH TEMPERATURES
FOR THE EASTERN SIERRA COMMUNITIES WILL WARM MOSTLY INTO THE
UPPER 70S TO 80S. WITH THE HOT TEMPERATURES, WIDESPREAD MODERATE
HEATRISK IS LIKELY FOR A MAJORITY OF WESTERN NV, WITH A FEW
ISOLATED MAJOR HEATRISK AREAS IN THE INNER BASIN.
* AT THIS MOMENT, BLENDED GUIDANCE SHOWS TUESDAY AS THE HOTTEST
DAY THIS WEEK. THE REASON IS THAT ON WEDNESDAY, A WEAK TROUGH
MOVES INTO THE PACIFIC NORTHWEST. THIS FEATURE WILL START TO
PUSH THE AFOREMENTIONED HIGH PRESSURE BACK TO THE SOUTHEAST. BY
FRIDAY, ANOTHER POTENTIALLY STRONGER TROUGH IS POISED TO MOVED
INTO THE PACIFIC NORTHWEST. THE ENSEMBLES ARE STARTING TO SHOW
BETTER AGREEMENT ON THE EVOLUTION OF THIS FEATURE COMPARED TO
PRIOR RUNS. AT THIS TIME, GUSTY WINDS START TO INCREASE AS EARLY
AS THURSDAY. WINDS ARE THE STRONGEST ON FRIDAY, WITH LIKELY
(60-90%) CHANCES FOR WINDS GREATER THAN 35 MPH. THESE WINDS
COMBINED WITH THE HOT TEMPERATURES AND DRY CONDITIONS WILL LEAD
TO FIRE WEATHER CONCERNS THURSDAY INTO SATURDAY. THERE ARE OTHER
ADDITIONAL IMPACTS TO AVIATION AND RECREATION, AS WELL AS LOW
10-20% CHANCES FOR SHOWERS AND STORMS NEAR THE OR BORDER ON
FRIDAY. WINDS REMAIN STRONG ON SATURDAY, THEN FINALLY START TO
DECREASE ON SUNDAY. TEMPERATURES DURING THIS TIME FRAME WITH
TREND COOLER, WITH AFTERNOON READINGS BETWEEN 5-10 DEGREES BELOW
AVERAGE FOR LATE JUNE. WE WILL BE RIDING THE WEATHER ROLLER
COASTER THIS WEEK! -MCKELLAR
