DISCUSSION
THIS WEEK LOOKS TO BE COOL, CALM, AND COLLECTED THROUGH
THANKSGIVING. THE ONLY EXCEPTIONS WILL BE IN THE NEXT 48 HOURS
WHERE FREEZING FOG IS LIKELY FOR FOG-PRONE SIERRA VALLEYS, SUCH AS
THE MARTIS VALLEY AND AROUND TRUCKEE, THIS MORNING. ADDITIONALLY,
A BRIEF LOW PRESSURE SYSTEM SKIRTS PAST TO THE NORTH, BRINGING
LIGHT CHANCES FOR SHOWERS ALONG THE OR BORDER MONDAY MORNING.
AHEAD OF THIS LOW, EXPECT SLIGHTLY INCREASED AFTERNOON BREEZES
TODAY WITH RIDGETOP GUSTS UP TO 40 MPH. DUE TO THOSE ENHANCED
BREEZES, THE THREAT FOR FREEZING FOG TO DEVELOP IS LESSER AHEAD OF
MONDAY MORNING. THOUGH, FOG MAY REDEVELOP IN THE MORNINGS BY MID-
WEEK AS RIDGING SETTLES BACK IN PLACE.
AFTERNOON HIGHS WILL LEAN ABOVE NORMAL ACROSS MUCH OF THE AREA
THIS WEEK, WITH HIGHS IN THE MID TO UPPER 50S. OVERNIGHT LOWS WILL
HOVER WITHIN A FEW DEGREES OF NORMAL WITH LOWS NEAR FREEZING. WITH
RIDGING RETURNING BY MID-WEEK OVER THE GREAT BASIN, THIS WILL
ALLOW FOR THE RETURN OF VALLEY INVERSIONS, BRINGING THE
POSSIBILITY FOR ISOLATED AIR QUALITY CONCERNS.
BEYOND THANKSGIVING, THE MODELS HAVE QUICKLY DETERIORATED IN
CONFIDENCE ON THE TIMING AND PLACEMENT OF THE NEXT STORM SYSTEM.
MOUNTAIN SNOW, VALLEY RAIN, AND GUSTY WINDS CAN BE EXPECTED OF
SOME FLAVOR AS EARLY AS FRIDAY THOUGH AMOUNTS, MAGNITUDE, AND
TIMING WILL HAVE TO WAIT TO BE RESOLVED UNTIL MID-WEEK AT THE
EARLIEST.

AVIATION
VFR CONDITIONS FOR ALL TERMINALS WILL PREVAIL TODAY, WITH THE ONLY

CONDITIONS. SURFACE WINDS MAY INCREASE A BIT THIS AFTERNOON AHEAD
OF THE LOW PRESSURE SYSTEM TO THE NORTH, WITH GUSTS UP TO 15 KTS
MAX.
