Weather Watch, 3/30/10

8:05 pm – new cell coming into Big Sur momentarily. Looks like it is carrying heavy rain, but is a small cell, so should pass quickly.

7:30 pm – significant rain has begun to fall up here. I wonder if it will turn to snow later tonight? Will keep all readers posted, until I turn in for the night.

9:00 am – I received 3/4 of an inch, Big Sur Valley reports 1/2 inch.

NOAA reports: “…LIGHT SHOWERS CONTINUE TO FALL ACROSS PORTIONS OF THE CWA. THE CURRENT RAINFALL WILL ADD TO THE WARM ADVECTION RAINS FROM LAST NIGHT….THE NEXT ROUND OF RAIN WILL ACCOMPANY A STRONG JET MAX CURRENTLY NOSING INTO NORCAL. …EXPECT SHOWERS TO INCREASE LATER TODAY FROM NORTH TO SOUTH. [A] STRONGER SYSTEM SLATED FOR WEDNESDAY. PREVIOUS FORECAST STILL LOOKS ON TRACK WITH COLDER AIR ALOFT MOVING IN OVERNIGHT AND TOMORROW. AT THE SAME TIME…A SFC LOW IS PROGGED TO SLIDE S ALONG THE COAST ON WEDNESDAY. THE EXACT TRACK OF THIS LOW IS STILL THE BIG QUESTION MARK. CURRENT MODELS DROP THE LOW RIGHT ALONG THE COAST WEDNESDAY KEEPING THE BULK OF THE RAIN ALONG THE COAST. HOWEVER…IF IT SHIFTS WESTWARD A LITTLE LESS PRECIP WILL FALL OVER THE CWA. ONE THING THAT DOES SEEM MORE CERTAIN IS THE INTRUSION OF MUCH COLDER AIR STARTING TONIGHT AND LASTING INTO THURSDAY. THE COLD TEMPS ALOFT WILL DO TWO THINGS…LOWER SNOW LEVELS AND DESTABILIZE THE ATMOSPHERE. SNOW LEVELS WILL LIKELY LOWER 2500-3000 FEET LATE TONIGHT THROUGH WEDNESDAY. MINOR SNOW ACCUMULATIONS WILL BE POSSIBLE WEDNESDAY AND WEDNESDAY NIGHT.”
