After Thanksgiving Storms
Looks like it could be a serious. Start preparing now. (I know I said I was taking the rest of the week off … I am, I really am, but thought we should all be aware of this ASAP.)
From my SLO meteorologist:
“A low pressure system will approach the Central Coast on Saturday
with increasing southerly winds and clouds. Periods of rain will
start Saturday night and continue through Sunday morning.
A much stronger storm system will move over San Luis Obispo County
Sunday evening into Monday with moderate gale-force to fresh gale
-force (32- to 46-mph) southerly winds late Sunday into Monday.
Periods of heavy rain is expected to start Sunday evening and
continue through Monday. Rain showers are expected to continue
into Tuesday/Wednesday. Total rainfall amounts could range between
4 and 6 inches in the Santa Lucia mountains above San Simeon,
Cambria and Cayucos. Other San Luis Obispo locations are expected
to range between 1 and 3 inches.”

Here is NOAA Monterey’s current report:
“RAIN CHANCES WILL INCREASE ACROSS THE BAY AREA AND CENTRAL COAST THROUGH THE DAY SATURDAY BUT NEED TO STRESS THAT SOUTHERN THIRD OF THE CWA (Ed. Note – that’s us) COULD STAY DRY RIGHT THROUGH SATURDAY AS THE SYSTEM DIGS OFF THE COAST. RAIN ON SATURDAY WILL BE WARM ADVECTION EVENT WITH HIGH BASED CLOUDS AND REALLY ONLY EXPECTING PERIODS OF LIGHT RAIN. EXCEPTION TO THAT WILL BE THE NORTH BAY WHERE OROGRAPHICS AND TONGUE OF 1.25 PWAT MAY LINE UP BETTER.
ANYWAY THERE WILL LIKELY BE A LULL IN THE RAIN AT SOME POINT LATER SATURDAY NIGHT OR INTO SUNDAY BEFORE THE NEXT ROUND OF UPPER DYNAMICS AND JET ENERGY ARRIVES. FOR NOW ITS ALL JUST COVERED WITH CONTINUED CHANCES OF RAIN ON SUNDAY. IT DOES LOOK LIKE PRETTY GOOD CONSENSUS BETWEEN THE GFS/GEM AND ECMWF THAT THE MAIN COLD FRONTAL PASSAGE WILL HOLD OFF UNTIL SUNDAY NIGHT OR MONDAY MORNING. THIS IS WHEN THE SURFACE FRONT…UPPER JET AND CORE OF COLD AIR ALOFT WILL FINALLY PASS OVERHEAD. WHEN THIS OCCURS IS THE WINDOW OF WHEN WIDESPREAD HEAVY RAIN WILL BE MOST LIKELY TO OCCUR. ITS STILL JUST TOO FAR OUT TO FINE TUNE DETAILS BUT IF THE TREND IS OUR FRIEND THEN SLOWER SOLUTIONS SEEM TO BE WINNING OUT IN TERMS OF BRINGING THE MOST ACTIVE WEATHER THROUGH THE BAY AREA.
UPPER TROUGH AXIS MOVING THROUGH LATER MONDAY INTO TUESDAY KEEPS SHOWER CHANCES IN THE FORECAST WITH A RIDGE BUILDING BACK IN BY THE MIDDLE OF NEXT WEEK.”
Could be a fun 4-5 days.
