MID-80S TO LOW 90S, WITH THE LAKE TAHOE AREA SEEING UPPER 70S. BY

INCREASING TO 20-30% FOR THURSDAY, MAINLY SOUTH OF US-50.
THE SYNOPTIC PATTERN WILL UNDERGO A SIGNIFICANT CHANGE TOWARDS
THE END OF THE WEEK AND INTO THE WEEKEND. WE'LL HAVE A CLOSED LOW
MOVING INTO THE PACIFIC NORTHWEST BY SATURDAY, PROGRESSING
EASTWARD. THIS TROUGH WILL BRING A NOTABLE COOLING TREND AND
INCREASED WINDS TO THE REGION.
TEMPERATURES WILL BEGIN TO DROP ON FRIDAY, WITH HIGHS ACROSS
WESTERN NEVADA VALLEYS FALLING INTO THE LOW 80S TO LOW 90S, AND
FURTHER COOLING INTO THE 70S BY SATURDAY AND SUNDAY. OVERNIGHT
LOWS WILL ALSO BECOME NOTICEABLY COOLER, ESPECIALLY IN THE SIERRA,
WITH SOME AREAS POTENTIALLY SEEING LOWS IN THE 30S BY SUNDAY
NIGHT.
GUSTY WINDS ARE EXPECTED FRIDAY, CONTINUING THROUGH SATURDAY, AS
THAT TROUGH APPROACHES. WEST/SOUTHWEST GUSTS OF 35-40 MPH ON
FRIDAY, AND GUSTS 40-45 MPH FOR WESTERN NEVADA AND THE SIERRA ON
SATURDAY. THESE WINDS WILL BE ACCOMPANIED BY CONTINUED DRY
CONDITIONS, LEADING TO ELEVATED FIRE WEATHER CONDITIONS. WE'LL
MONITOR THOSE TWO DAYS AS THEY GETS CLOSER AND SEE IF ANY
PRODUCTS ARE WARRANTED. THEN WINDS SUNDAY AND MONDAY ARE EXPECTED
TO DIMINISH AS THE TROUGH MOVES EASTWARD, LEAVING CLEAR SKIES AND
COOL, DRY CONDITIONS.
