AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RENO NV
129 PM PDT MON APR 14 2025
KEY MESSAGES
* WARMER WEATHER THROUGH WEDNESDAY WITH SNOWMELT CONTINUING TO
RESULT IN STREAMFLOWS RUNNING FAST AND COLD.
* AFTERNOON SHOWERS AND THUNDERSTORMS ARE POSSIBLE THROUGH MIDWEEK
WITH ISOLATED AREAS OF HEAVY RAINFALL POSSIBLE.
* A COLD FRONT MAY BRING LIGHT MOUNTAIN SNOW, MORE THUNDERSTORMS,
GUSTY WINDS, AND COOLER WEATHER THURSDAY AND FRIDAY BEFORE A
WARMING AND DRYING TREND PREVAILS EASTER WEEKEND.
DISCUSSION
* SEASONABLY MILD CONDITIONS WILL PERSIST EARLY THIS WEEK, WITH
TUESDAY AFTERNOON BRINGING THE WARMEST TEMPERATURES. EXPECT
HIGHS ACROSS W.NEVADA TO CLIMB INTO THE UPPER 70S, WHILE SIERRA
VALLEYS SEE MID-60S. AFTERNOON HIGHS AND LOWS BOTH WILL REMAIN
SEASONABLY MILD, RUNNING ABOUT 10 DEGREES ABOVE AVERAGE, WITH
LOWS ONLY DROPPING INTO THE UPPER 40S TO NEAR 50 ACROSS W.NEVADA
BY WEDNESDAY MORNING. THE MILD WEATHER WILL CONTINUE TO INCREASE
SNOWMELT RESULTING IN COLD, FAST-FLOWING CREEKS/STREAMS.
* WE'LL BE SEEING AN INCREASED THUNDERSTORM POTENTIAL OVER THE
NEXT SEVERAL DAYS AS THE DIFFLUENT REGION OF A CLOSED LOW
MEANDERS OVER THE REGION. THE SIERRA AND SIERRA FRONT WILL BE
THE FAVORED AREAS FOR STORM DEVELOPMENT (15-25% CHANCES) TUESDAY
THROUGH THURSDAY, WITH WEDNESDAY SEEING THE HIGHEST CHANCES
(25-40%). STORM MOTIONS WILL BE SLOWER (<10KTS) SO A FEW AREAS
COULD SEE BRIEF HEAVY RAINFALL, BUT THE OVERALL THREAT FOR FLASH
FLOODING IMPACTS SHOULD REMAIN LOW (<5%) CONSIDERING WE DON'T
HAVE THE EFFICIENT SUMMER RAIN PROCESSES IN PLACE YET.
* THE CLOSED LOW WILL BEGIN TO MERGE WITH AN UPPER LEVEL TROUGH
ACROSS THE PACIFIC NORTHWEST ON THURSDAY. THIS WILL AID IN
SENDING A BACKDOOR COLD FRONT THROUGH THE REGION WHICH COULD
LOWER SNOW LEVELS NEAR 6500-7000' WITH LIGHT MOUNTAIN SNOW,
ISOLATED SIERRA THUNDERSTORMS, AND GUSTY NORTHERLY WINDS BEHIND
THE FRONT. WHILE NOT A BIG WIND EVENT, GUSTS COULD REACH 35-40
MPH WITH STRONG SUSTAINED NORTHERLY WINDS OF 20-30 MPH,
PARTICULARLY ACROSS PORTIONS OF THE W.NEVADA BASIN AND RANGE.
THIS COULD CREATE CROSSWINDS HAZARDS AND AREAS OF BLOWING DUST
ALONG SECTIONS OF I-80 AND US-50 ACROSS WESTERN NEVADA.
* AFTER A FEW LINGERING RAIN AND SNOW SHOWERS ACROSS MONO COUNTY
ON FRIDAY MORNING, THE UPPER LOW WILL BEGIN TO DEPART THE AREA
WITH A WARMING AND DRYING TREND EXPECTED INTO THE WEEKEND.

AVIATION
VFR CONDITIONS PREVAIL TODAY WITH SOME CUMULUS BUILD-UPS IN THE
SIERRA SOUTH OF TAHOE. SHOWERS AND PERHAPS A STRAY THUNDERSTORM OR
TWO APPEAR POSSIBLE THIS AFTERNOON BETWEEN KTVL AND KMMH,
ALTHOUGH ODDS OF LIGHTNING WITHIN 10 MILES OF KTVL AND KMMH ARE
ONLY 10% OR LESS FROM 20Z TO 02Z. IMPACTS FROM SHOWERS AND
THUNDERSTORMS ARE MOST LIKELY ON TUESDAY AND WEDNESDAY AFTERNOON,
ESPECIALLY AT SIERRA TERMINALS.
INCREASED WINDS WILL YIELD AN INCREASING CHANCE OF MOUNTAIN WAVE
TURBULENCE AND LLWS LATE WEDNESDAY NIGHT INTO THURSDAY MORNING AS
A COLD FRONT TRACKS ACROSS WESTERN NEVADA. THIS COULD YIELD BANDS
OF LIGHT TO MODERATE RAINFALL FOR W.NV TERMINALS WITH A MIX OF
RAIN AND SNOW FOR SIERRA TERMINALS AS SNOW LEVELS DROP TO NEAR
6500-7000' BY THURSDAY MORNING. SALAS/FUENTES
