Tonight’s sunset.

For this afternoon’s forecast discussion, see prior post. This COULD get very interesting this weekend and early next week.

BTW, tomorrow I have the BSMAAC meeting to attend, AND it is our annual ladies holiday luncheon at the Post Ranch Inn. So, guess who will not be watching the weather until evening?

Okay, here is this afternoon’s forecast discussion:

THE UPSHOT IS THAT SHOWERS WILL DEVELOP OVER THE REGION BY
SATURDAY...AND WILL CONTINUE INTO THE MIDDLE OF NEXT WEEK. 
TIMEHEIGHT CROSS SECTIONS INDC THAT THUNDER IS POSSIBLE...
SO HAVE ADDED IT TO THE FCST. WITH THE WET BULB ZERO AS LOW
AS 1000 FEET AT TIMES SMALL HAIL IS LIKELY WITH THE CONVECTION. 
TEMPS WILL BE COLD WITH HIGHS IN THE 40S ACROSS THE DISTRICT 
AND OVERNIGHT LOWS IN THE 30S. THE SNOW LEVEL WILL VARY ANYWHERE 
FROM 1500 TO 2500 FEET...AND DOWN TO 1000 FEET AT TIMES. WINTER 
WEATHER ADVISORIES MIGHT BE NEEDED BY THE END OF THE WEEKEND AND 
EARLY NEXT WEEK FOR SNOW ON THE BAY AREA HILLS...
POSSIBLY AFFECTING ROADS IN THE SANTA CRUZ MOUNTAINS AND THE 
NORTH BAY HILLS. AS THE WEEKEND APPROACHES THE DETAILS SHOULD 
BECOME CLEARER CONCERNING SNOW LEVELS AND HOW MUCH SNOW IN THE 
HILLS.

I am waiting for the afternoon models to be analyzed, but until then, this was posted for the 9 am discussion:

"TODAY SHOULD BE THE LAST DRY AND WARM DAY FOR QUITE A WHILE."
So, whatever you do, ENJOY!

And here’s the most recent discussion (3 am) from NWS:

LATEST MODELS BRING THE FIRST CHANCES OF RAIN TO THE NORTHERN ZONES 
AS EARLY AS FRIDAY NIGHT...THEN PRECIP CHANCES SPREAD THROUGH 
THE REMAINDER OF THE CWA ON SATURDAY AS THE UPPER LOW CONTINUES 
TO MOVE SOUTHWARD JUST SKIRTING THE WEST COAST. THE ENTIRE 
DISTRICT WILL SEE SIGNIFICANTLY COLDER TEMPERATURES ON 
SATURDAY AS A COLD AIRMASS SPREADS ACROSS THE AREA FROM 
THE NORTH. THE COOL AND SHOWERY REGIME WILL CONTINUE 
THROUGH MIDWEEK AS THE UPPER TROUGH REMAINS ANCHORED 
ALONG THE WEST COAST. AS 700 MB TEMPS ARE PROGGED TO LOWER 
TO MINUS 16 DEGREES AND 1000-500 MB THICKNESS VALUES DROP 
AS LOW AS 526 MB...SNOW LEVELS ARE EXPECTED TO LOWER TO
 2000-3000 FEET OR LOWER BY TUESDAY.

 COOL AND UNSETTLED WEATHER TO PERSIST BEYOND MIDWEEK AS THE
 DISTRICT REMAINS IN AN ACTIVE WEATHER PATTERN.
