DISCUSSION
WE TIED A SNOWFALL RECORD AT THE RENO INT'L AIRPORT TODAY WITH
OFFICIALLY A TRACE OF SNOW, THANKS TO THE COLD FRONTAL PASSAGE
TODAY. EXPECT A VERY COLD MORNING TODAY WITH LOWS NEAR TO BELOW
FREEZING FOR MUCH OF THE AREA. OVERNIGHT LOWS REBOUND A BIT
TUESDAY MORNING, BUT WILL REMAIN ON THE CHILLY SIDE. AS FOR TODAY,
EXPECT BREEZY AFTERNOON WINDS WITH HIGHS BACK TO THE MID 60S
(VALLEYS) AND UPPER 50S (SIERRA).
WE REMAIN IN A TROUGHING UPPER-LEVEL PATTERN, WITH A LOW SITTING
OFF THE COAST OF BAJA CALIFORNIA AND HIGH PRESSURE BUILDING OFF
THE COAST OF THE PACNW. THIS WILL ALLOW FOR WEAK PRESSURE
GRADIENTS ALOFT, LETTING US SLOWLY WARM UP THROUGH THE WEEK (AS
THE RIDGE PROGRESSES EASTWARD) WITH LIGHT AND TYPICAL DIURNAL
WINDS. DRY CONDITIONS WILL ALSO ACCOMPANY THE WARMING TREND.
LOOKING TOWARDS THE HOLIDAY WEEKEND, THERE'S A ~40% CHANCE TO SEE
HIGHS ABOVE 90 DEGREES IN RENO AND ~40% CHANCE TO SEE OVER 80
DEGREES IN TAHOE. SHOWER CHANCES LOOK SLIM TO NONE FOR THE WEEKEND
AS WELL.
