DISCUSSION
ONCE AGAIN THIS MORNING WE'VE GOT SOME NOCTURNAL CONVECTION
ACROSS THE SIERRA AND WESTERN NV (30-40% CHANCE). THESE LIGHT
SHOWERS WILL CONTINUE THROUGH THIS MORNING RIGHT UP UNTIL THE
SLIGHTLY STRONGER SHOWERS START POPPING UP ACROSS WESTERN NV
AROUND 10-11AM. SHOWER CHANCES THIS AFTERNOON, 50-60%, WILL BE
MAINLY FOCUSED OVER WESTERN NV AND THE SIERRA CREST FROM TAHOE
SOUTHWARD. WE'LL STILL HAVE AROUND A 30% CHANCE FOR LIGHTNING THIS
AFTERNOON AS WELL. TODAY WILL BE THE COOLEST DAY OVER THE NEXT 7
DAYS WITH HIGHS CLOSE TO 60 IN LOWER VALLEYS AND NEAR 50 IN THE
SIERRA.
MONDAY THROUGH WEDNESDAY, HIGH PRESSURE WILL ONCE AGAIN TAKE OVER
AND WE'LL QUICKLY WARM BACK UP TO AROUND 80 DEGREES BY WEDNESDAY
(70S IN THE SIERRA). MONDAY WILL BE A BIT BREEZY ACROSS THE REGION
WITH GUSTS 20-25 MPH IN WESTERN NV AND NE CA. OTHERWISE, THIS
WEEK THROUGH WEDNESDAY WILL BE SUNNY AND WARM!
JUMPING AHEAD TO LATER THIS WEEK, ENSEMBLES ARE SHOWING SIGNALS
OF SHOWERS ALONG THE SIERRA CREST THURSDAY THROUGH NEXT WEEKEND.
UNCERTAINTY IS FAIRLY HIGH RIGHT NOW, BUT STAY TUNED LATER THIS
WEEK AS FORECAST CERTAINTY INCREASES.

AVIATION
LIGHT SHOWERS WILL CONTINUE THROUGH THIS MORNING RIGHT UP UNTIL
WE SEE MORE WIDESPREAD SHOWERS LATER IN THE MORNING. THESE SHOWERS
AND THUNDERSTORMS WILL BE THE MAIN CONCERN THIS AFTERNOON FOR ALL
REGIONAL TERMINALS (50-60% CHANCE). SHOWERS MAY INITIATE AS EARLY
AS 18Z THIS MORNING AND WILL MOVE SOUTH AND EAST THROUGH THE
AFTERNOON HOURS. THE MOST INTENSE SHOWERS ARE EXPECTED TO
DISSIPATE BY 06Z TONIGHT. THE STRONGEST THUNDERSTORMS WILL BE
CAPABLE OF BRIEF DOWNPOURS, POTENTIALLY BRINGING BRIEF MVFR
CONDITIONS, GUSTY AND ERRATIC WINDS, AND LIGHTNING. OTHERWISE,
BREEZY N-NE WINDS ARE FORECASTED INTO THE EVENING.
MONDAY THROUGH THE FIRST HALF OF THIS WEEK, DRY AND SUNNY
CONDITIONS RESUME WITH TYPICAL AFTERNOON WESTERLY BREEZES.
