CLOUD COVER WILL STEADILY INCREASE TODAY DUE TO TWO SMALL
SHORTWAVES OFF THE COAST OF THE PACNW. THIS CAN BE SEEN IN 500 HPA

THE SHORTWAVE PASSES, EXPECT CLEARING SKIES.
SUNNY SKIES WILL BE SHORT-LIVED AS A SECOND SHORTWAVE FEATURE
STARTS TO INFLUENCE THE AREA TUESDAY AND WEDNESDAY. EXPECT GUSTIER
RIDGE WINDS (UP TO 35 MPH GUSTS) TUESDAY AND THEN LIGHT (<20%
CHANCE) SNOW SHOWERS WEDNESDAY MORNING/EARLY AFTERNOON FOR THE
TAHOE BASIN AND NORTHWARD INTO NE CA AND N WASHOE COUNTY. LITTLE
TO NO SNOW ACCUMULATIONS IS FORECAST WITH THIS SMALL SCALE
FEATURE.
DESPITE THOSE COUPLE OF SHORTWAVES, A SLOW BUT STEADY WARMING
TREND IS FORECAST THROUGH AT LEAST THE WEEKEND AS HIGH PRESSURE
BUILDS. THIS WILL ALLOW FOR THE RETURN OF VALLEY INVERSIONS,
THOUGH FOG PRODUCTION MAY BE DELAYED UNTIL MID-WEEK AS LOW-LEVEL
PROFILES ARE QUITE DRY. ANOTHER TROUGH AS EARLY AS SATURDAY MAY
INFLUENCE THE AREA THOUGH DETAILS ON TIMING AND INTENSITY REMAIN
UNCERTAIN.
