AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RENO NV
1222 AM PDT FRI JUN 12 2026
KEY MESSAGES
* VERY WARM AND DRY WEATHER CONDITIONS THROUGH THE WEEKEND WITH
LOW CHANCES OF SHOWERS AND ISOLATED STORMS IN THE AFTERNOONS FOR
MONO COUNTY.
* HOTTER CONDITIONS ARE EXPECTED NEXT WEEK, RESULTING IN MODERATE
TO MAJOR HEATRISK BY MID NEXT WEEK.
DISCUSSION
A SINGLE THUNDERSTORM DEVELOPED SOUTH OF MONO LAKE TODAY BEFORE
DISSIPATING AS IT TRAVERSED TO THE SOUTHEAST. EXPECT DAILY
THUNDERSTORM CHANCES (15%) FOR MONO COUNTY THIS WEEKEND AS CAPE
VALUES RANGE FROM 300-400 J/KG. DCAPE VALUES ARE ALSO OVER 1400
J/KG, MEANING OUTFLOW GUSTS COULD RANGE FROM 45-55 MPH. THIS
ADDITIONAL SYNOPTIC FORCING IS OWED TO A LOW PRESSURE SYSTEM
CYCLING OVER THE SAN FRANCISCO BAY AREA.
THE OTHER MAIN STORY IS THE INCOMING HEAT. AFTERNOON WEEKEND HIGHS
WILL BE IN THE MID 90S FOR VALLEYS AND MID 80S FOR SIERRA
COMMUNITIES. AS HIGH PRESSURE BUILDS OVER BRITISH COLUMBIA THROUGH
NEXT WEEK, WE HEAT UP FURTHER. THERE IS A 40% CHANCE FOR RENO TO
HIT 100F NEXT TUESDAY, WITH A 15% CHANCE SOUTH LAKE TAHOE WILL
REACH 90F OR ABOVE. AS SUCH, MODERATE HEATRISK EXTENDS INTO THE
TAHOE BASIN, WITH AREAS OF MAJOR HEATRISK IN THE LOWER VALLEYS
EAST OF US-385. WITH SUMMER HEAT SETTLING IN NICELY, GET BACK
INTO THE ROUTINE OF DRINKING PLENTY OF WATER AND REAPPLYING
SUNSCREEN.

AVIATION
VFR CONDITIONS EXPECTED FOR ALL TERMINALS THROUGH THE WEEKEND,
WITH THE ONLY EXCEPTION OF KMMH WHERE BRIEF MVFR CONDITIONS MAY
ARISE IN THE WAKE OF ANY SHOWER OR THUNDERSTORM DEVELOPMENT. ODDS
ARE 15% OR LESS, THOUGH SHOWERS THAT DEVELOP WILL BE CAPABLE OF
GUSTY AND ERRATIC WINDS WITH BRIEF HEAVY RAINFALL.
WARMING CONTINUES THROUGH MID NEXT WEEK, WHICH MAY PRODUCE DENSITY
ALTITUDE IMPACTS FOR KRNO/KCXP/KMEV.
