THE AREA AND BRINGING PRECIPITATION CHANCES TO THE EASTERN SIERRA.

TEMPERATURES REMAIN ABOVE NORMAL.
DISCUSSION
THROUGH MONDAY.
AFTER ANOTHER DAY OF QUIET WEATHER TODAY, A SHORTWAVE TROUGH WILL
MOVE THROUGH THE PACNW AND GREAT BASIN ON WEDNESDAY. NOT OVERLY
STRONG AND MORE OF A GLANCING BLOW, CHANCES FOR WIDESPREAD,
IMPACTFUL WINDS (40+ MPH) ARE LOW (LESS THAN 25%). INSTEAD, ANY
WIND IMPACTS ARE LIKELY TO BE THE RESULT OF LOCALIZED DOWNSLOPING
IN PLACES LIKELY US-95 NEAR DESERT ROCK/MERCURY AND US-395 IN THE
OWENS VALLEY. THE LATTER HAS THE GREATEST POTENTIAL (~50%), AND
THESE PROBABILITIES MAY BE UNDERSTATED A BIT WITH THE SEEMINGLY
FAVORABLE SETUP. BEYOND THE WINDS, IT IS WORTH NOTING THAT THERE
ARE 20-30% POPS ON WEDNESDAY IN THE EASTERN SIERRA. AMOUNTS WILL
LIKELY BE LIGHT AS CHANCES FOR 0.25"+ ARE ONLY ~20%, RESULTING IN
~30% PROBABILITIES FOR 1"+ OF SNOW ABOVE 9,000 FEET. PRECIPITATION
CHANCES AND WINDS QUICKLY DIMINISH BY THURSDAY MORNING.
OTHER THAN WEDNESDAY'S SYSTEM, THE WEATHER ACROSS THE REGION LOOKS
RATHER QUIET. WINDS REMAIN LIGHT, ABOVE-NORMAL TEMPERATURES PERSIST,
AND PRECIPITATION CHANCES STAY BELOW 10%. COOLEST TEMPERATURES
EXPECTED THURSDAY, BUT EVEN THEN HIGHS ARE FORECAST TO BE BETWEEN 70
AND 85 DEGREES IN MOST LOCATIONS.
