AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RENO NV
1210 PM PDT WED APR 29 2026
KEY MESSAGES
* WARMER AND DRIER WEATHER PREVAILS THROUGH THE EARLY WEEKEND WITH
LOW CHANCES (5-10%) OF AFTERNOON SHOWERS NEAR THE SIERRA CREST
TODAY THROUGH FRIDAY.
* POTENTIAL FOR RAIN AND MOUNTAIN SNOW SHOWERS, THUNDERSTORMS, AND
GUSTY WINDS RETURN LATE THIS WEEKEND INTO EARLY NEXT WEEK.
DISCUSSION
WARMING AND DRYING TREND KICKS OFF TODAY AS LOW PRESSURE EXITS THE
REGION AND BRIEF SHORTWAVE RIDGING PREVAILS. DRY, NORTH TO NORTHWEST
FLOW WILL SCOUR OUT MOST OF THE MID TO UPPER LEVEL MOISTURE WITH
RELATIVELY CLEAR SKIES THE NEXT COUPLE OF DAYS. ONLY EXCEPTIONS WILL
BE (1) AFTERNOON CUMULUS BUILDUPS WITH A ~10% CHANCE OF A SHOWER OR
TWO ALONG THE SIERRA CREST AND (2) THE FOG POTENTIAL IN THE TRUCKEE
VICINITY. FORECAST SOUNDINGS DEPICT PLENTY OF DRY AIR IN THE MID TO
UPPER LEVELS USHERED IN BY THE NORTH-NORTHWEST FLOW, BUT ENOUGH
SURFACE LEVEL MOISTURE TO ALLOW FOR AREAS OF FOG TO FORM LATE EACH
NIGHT INTO THE EARLY MORNING. WE'RE ALL FAMILIAR WITH THE DENSE FOG
CULPRITS IN TRUCKEE AND ALONG INTERSTATE 80 NEAR BOCA AND DONNER
LAKE, SO TAKE IT SLOW DURING THOSE MORNING COMMUTES. ASIDE FROM
THOSE CONCERNS, BUST OUT THE SUNSCREEN AND ICED BEVERAGES TO
PROPERLY ENJOY THE WARMER DAYS WITH HIGHS IN THE UPPER 60S AND UPPER
70S BY SATURDAY. SOME WARMER LOWER VALLEYS MAY REACH TOWARD 80
DEGREES BY SATURDAY AFTERNOON.
THERE IS ALSO AN HONORABLE MENTION FOR A WEAK, DRY FRONTAL FEATURE
THAT IS PROJECTED TO PASS THROUGH EASTERN NV ON THURSDAY WHICH MAY
KICK OFF SOME STRONGER BREEZES FOR AREAS EAST OF HIGHWAY 95 AND
SOUTH OF INTERSTATE 80. SOME RESIDUAL NORTHEAST-EAST ENHANCED
FLOW MAY RESULT IN STRONGER GUSTS FOR MINERAL AND MONO COUNTY
RIDGELINES THROUGH EARLY FRIDAY MORNING.
AFTER THE RELATIVELY QUIET WEATHER, WE ARE LOOKING AT A POTPOURRI OF
WEATHER STARTING ON SATURDAY AND TAKING RESIDENCE THROUGH EARLY NEXT
WEEK. THERE ARE STILL SOME QUESTION MARKS ON THE FINER DETAILS, BUT
AFTER SOME WIND INCREASES AND ISOLATED SHOWERS ON SATURDAY, YOU CAN
PLAN ON THE RETURN OF UNSETTLED WEATHER SUNDAY INTO TUESDAY. WE'RE
TALKING COOLER CONDITIONS, POTENTIAL FOR RAIN AND MOUNTAIN SNOW
SHOWERS, THUNDERSTORMS AND SOME WINDS. WHILE THERE ARE STILL SOME
DISCREPANCIES IN THE TRACK AND TIMING OF THE SYSTEM, FOR NOW, THE
PRECIPITATION POTENTIAL PEAKS MONDAY INTO TUESDAY. BLENDED
GUIDANCE DOES SHOW SNOW LEVELS DROPPING FOR A BRIEF PERIOD OF TIME
MONDAY INTO TUESDAY WITH POTENTIAL FOR SNOW IMPACTS TO THE SIERRA
PASSES. KEEP AN EYE ON THE FUTURE FORECAST UPDATES BECAUSE THERE
COULD BE MORE EXTENDED IMPACTS TO SIERRA TRAVEL IF THE SYSTEM
HANGS ON LATER IN THE WEEK.
BEYOND THIS SYSTEM, HIGH PRESSURE WILL NUDGE THE COLD SYSTEM
EASTWARD WITH ANOTHER WARMER/DRIER PERIOD IN STORE FOR NEXT
WEDNESDAY INTO LATE NEXT WEEK. WE'RE WELL INTO THE UPS/DOWNS OF
TRUE SPRING HERE IN NORTHERN NV AND CA.

AVIATION
VFR CONDITIONS AND LIGHT BREEZES PREVAIL TODAY. PLAN ON LOW TO MID
LEVEL CUMULUS BUILDUPS THIS AFTERNOON, ESPECIALLY ALONG THE SIERRA
CREST. THERE IS A 10% CHANCE OF SHOWERS AT KMMH-KTRK-KTVL THROUGH
THIS EVENING.
THERE IS A 15-25% CHANCE OF ANOTHER ROUND OF FZFG AND IFR/LIFR
CONDITIONS AT KTRK BETWEEN 10Z AND 16Z THURSDAY MORNING. SIMILAR
PROGRESSION TO THE FZFG THAT WE SAW THIS MORNING, IT SHOULD MIX OUT
WITH INCREASING CIGS AND VIS.
