DISCUSSION
SCATTERED SHOWERS HAVE REDEVELOPED THIS AFTERNOON AS DAYTIME
HEATING INCREASES INSTABILITY. THE HIGHEST CHANCES (40-60%) WILL
REMAIN ALONG THE EASTERN SIERRA, WITH A 10-15% CHANCE OF ISOLATED
THUNDERSTORMS. FARTHER EAST OF US-95 IN WEST-CENTRAL NEVADA,
INCLUDING SOUTHERN MONO COUNTY, SHOWER CHANCES DROP TO 20-40%,
THOUGH THUNDERSTORM POTENTIAL INCREASES SLIGHTLY TO 15-20%.
ELSEWHERE, ONLY ISOLATED SHOWERS ARE EXPECTED (10-20%).
SHOWERS MAY BRING BRIEF LIGHT TO MODERATE RAIN, WITH OCCASIONAL
PELLET SHOWERS. IN THE SIERRA, SNOW LEVELS WILL REMAIN NEAR 7,000
FEET WITH SCATTERED LIGHT SNOW, THOUGH THE LIKELIHOOD OF MORE THAN
AN INCH OF ACCUMULATION ON PASSES IS GENERALLY LOW (UNDER
15-20%). SHOWER ACTIVITY DECREASES TUESDAY, WITH 35-45% CHANCES
LINGERING ALONG THE EASTERN SIERRA (15-20% THUNDERSTORM RISK),
BEFORE TAPERING TO 10-15% FOR SHOWERS AND LESS THAN 5% FOR STORMS
BY WEDNESDAY. AFTER THAT, DRY CONDITIONS WILL PREVAIL THROUGH THE
BEGINNING OF THE WEEKEND.
WE’LL REMAIN SEASONABLY COOL TODAY WITH HIGHS NEAR 60 DEGREES
ACROSS WESTERN NEVADA AND NEAR 50 DEGREES FOR SIERRA COMMUNITIES.
A WARMING TREND WILL THEN COMMERCE THROUGH THE WEEKEND AS HIGHS
INCREASE INTO THE MID AND UPPER 60S FOR W.NEVADA VALLEYS BEFORE
RETURNING TO THE 70 DEGREE MARK ON WEDNESDAY WITH LOW 60S FOR
SIERRA VALLEYS. WARMING CONTINUES THROUGH THE WEEKEND WITH FRIDAY
AND SATURDAY TARGETING A RETURN TO THE 80 DEGREE MARK FOR W.NEVADA
VALLEYS AND NEAR 70 FOR SIERRA VALLEYS.
GENERALLY LIGHT NORTHERLY BREEZES WILL PERSIST THROUGH THE WEEK,
WITH SOUTHWEST WINDS INCREASING BY SATURDAY AS A CLOSED LOW
APPROACHES THE WEST COAST. SHOWERS MAY BEGIN LATE SATURDAY IN FAR
NORTHEAST CALIFORNIA, THEN EXPAND INTO THE SIERRA AND WESTERN
NEVADA WITH SHOWER AND ISOLATED THUNDER CHANCES POTENTIALLY
EXTENDING INTO EARLY NEXT WEEK. CONFIDENCE REMAINS LOW REGARDING
THE SYSTEM’S TIMING AND TRACK, WHICH IS TYPICAL FOR SLOW-MOVING
SPRING CUT-OFF LOWS. FUENTES
AVIATION
