DISCUSSION
SHOWERS AND THUNDERSTORMS MARCH NORTH THIS AFTERNOON, BRINGING A
HANDFUL OF LIGHTNING STRIKES, BRIEF HEAVY RAINFALL, AND GUSTY
OUTFLOW WINDS. AS THE DAY PROGRESSES, SHOWERS WILL BECOME MORE
WIDESPREAD IN COVERAGE, WITH THE MAIN CONCERN OF A FEW SEVERE
WIND GUSTS, PRIMARILY FROM MICROBURSTS DUE TO STRONG DCAPE VALUES
(500-700 J/KG), OUT IN THE WESTERN NEVADA BASIN AND RANGE. LIKE
LAST NIGHT, IT'S LIKELY THAT SOME PERSISTENT SHOWERS AND
THUNDERSTORMS WILL LINGER THROUGH THE OVERNIGHT HOURS.
AS THE LOW TO OUR SOUTH MOVES INLAND TONIGHT AND INTO TOMORROW,
UPPER LEVEL FLOW WILL SWITCH TO A N-NE DIRECTION. THIS WILL ALLOW
FOR ANOTHER ROUND OF SHOWERS, WITH LIGHT SNOW SHOWERS IN THE
SIERRA OF MONO COUNTY. SNOW LEVELS BOTTOM OUT AROUND 8 KFT CLOSE
TO MIDNIGHT, WHICH COINCIDES WITH THE BEST CHANCE FOR SHOWERS.
ACCUMULATIONS ALONG THE LOWER ROADS AND PASSES WILL BE LITTLE TO
NONE, BUT SLUSHY CONDITIONS ARE STILL POSSIBLE. PEAKS IN MONO
COUNTY WILL SEE UP TO 5 INCHES WITH 1-3 INCHES POSSIBLE BELOW
8000' IN ISOLATED LOCATIONS.
OVERALL, THE HIGHEST QPF WILL BE FOUND OUT IN THE WESTERN NEVADA
BASIN AND RANGE AND SOUTHERN MONO COUNTY WITH UP 0.5-0.75" LIKELY.
SHOWERS WILL LIGHTEN UP SUNDAY AS THE LOW MOVES FURTHER EAST,
USHERING IN GUSTY AFTERNOON WINDS. ADDITIONALLY, SUNDAY WILL BE
THE COOLEST DAY OF THE WEEK, WITH HIGHS IN THE 50S AND 60S
(MOUNTAINS AND VALLEYS, RESPECTIVELY). A BRIEF SHORTWAVE TROUGH
WILL BRING INCREASED WIND GUSTS MONDAY, BUT WE ALSO START TO WARM
UP.
LOOKING INTO NEXT WEEK, HIGH PRESSURE RETURNS, BRINGING
TEMPERATURES BACK UP TO THE 70S AND 80S (MOUNTAINS AND VALLEYS,
RESPECTIVELY). LIGHT WINDS AND DRY CONDITIONS WILL ALSO BE ON THE
DOCKET FOR EARLY NEXT WEEK. ANOTHER SHORTWAVE THURSDAY MAY BRING
LIGHT SHOWERS ALONG THE SIERRA, HOWEVER, STAY TUNED FOR MORE
DETAILS AS WE GET CLOSER.

THIS AFTERNOON, WITH SOME LINGERING INTO THE EVENING AND OVERNIGHT
HOURS. HOWEVER, THE MOST INTENSE SHOWERS ARE EXPECTED TO

CAPABLE OF BRIEF DOWNPOURS, POTENTIALLY BRINGING BRIEF MVFR

OTHERWISE, BREEZY W-SW WINDS ARE FORECASTED THIS AFTERNOON BEFORE
SHIFTING N-NE TONIGHT AND THROUGH TOMORROW MORNING.
LIGHT SHOWERS WILL RETURN TONIGHT, PROGRESSING IN A NORTH TO
SOUTH FASHION, IMPACTING ALL TERMINALS WITH PERIODS OF BRIEF MVFR
CONDITIONS. -SHSN POSSIBLE FOR KMMH AFTER 04/06Z. SHOWERS LIGHTEN
UP THROUGH SUNDAY AFTERNOON, BUT WILL BE REPLACED WITH GUSTY
WINDS BETWEEN 20-30 KTS.
