3:30 pm – only up another .12″ but look at what’s on tap for tomorrow?

10:45 am – rain has picked up again, with a rate of 1.31″/hour, for a total thus far today of 1.23″ and 2.75″for the storm. It is supposed to be scattered today, with the heavy rain expected tomorrow. That will be interesting, that’s for sure.

6:00 am – woke to 2.42″ for the storm, and it is still raining. Got just under an inch since midnight, and given the 1″ we got before I turned in for the night, it looks like the .42″ came between 10 and 12 while I lay quietly oblivious and sound asleep. Okay, let me catch up with traffic, have my coffee, and then I’ll be back. Please feel free to share your totals.Cal, how did you far out there by Lake Nacimiento?

MAIN FOCUS OF THE SHIFT REMAINS ON THE SECOND HALF OF THE WEEK AS
THE RIDGE OVERHEAD IS REPLACED BY A MOIST WEST-SOUTHWEST FLOW
ALOFT. THIS WILL ALLOW PW VALUES POTENTIALLY EXCEEDING 1.5 INCHES
TO MOVE ACROSS OUR REGION. THIS WILL BRING RAIN BACK INTO THE
PICTURE STARING OVER THE NORTH BAY ON THURSDAY AND EVENTUALLY
ACROSS THE ENTIRE CWA. RAIN CHANCES WILL CONTINUE INTO THE
WEEKEND. SIMILAR TO PREVIOUS MODEL RUNS…ALL INDICATIONS ARE THE
GREATEST ACCUMULATIONS WILL BE OVER THE NORTH BAY WITH AMOUNTS
GENERALLY DECREASING THE FARTHER SOUTH YOU GO. LATEST CNRFC
NUMBERS SHOW LOCALLY 3 TO 5 INCHES BY LATE SATURDAY NIGHT IN SONOMA
COUNTY…2 TO 3 INCHES FOR THE REMAINDER OF THE NORTH BAY PLUS SC
MOUNTAINS AND THE SANTA LUCIAS…1 TO 2 INCHES FOR MOST OF SF
BAY…HALF AN INCH TO AN INCH FOR THE SOUTH BAY AND THE REMAINDER
OF THE CWA. ADDITIONAL RAINFALL IS LIKELY ON SUNDAY SO 6 DAY
NUMBERS ISSUED TOMORROW SHOULD SEE EVEN HIGHER VALUES.

WILL ISSUE AN SPS THIS MORNING AS A HEADS UP AND WILL LIKELY
INCREASE THE POPS PLUS MENTION OF HEAVY RAIN IN THE GRIDS. WILL
CONTINUE TO HIGHLIGHT THAT THE OVERALL CONFIDENCE IS HIGH WHILE THE
CONFIDENCE FOR THE SOUTHERN EXTENT OF THE HEAVIER RAIN REMAINS
QUITE A BIT LOWER.

From my favorite SLO Weathercaster, John Lindsey: 1/20 “At this time, the ridge of high pressure begins to weaken early next week followed by increasing chances of rain near mid-week. Unsettled weather is expected to continue through February.”

1/21 “A major change in the weather pattern is forecast Monday night into Wednesday morning, as a low-pressure system near Baja moves northward along the Central Coast. Since the low is moving out of the south, it will contain subtropical moisture and snow levels will remain above 8,000 feet.

This system will produce increasing southerly winds, cooler temperatures and much-needed rain. At this time, rainfall amounts are expected to range between 0.25 and 0.75 of an inch. Another chance of rain is forecast next Thursday. The unsettled weather pattern will continue through the first week of February.”
