In regards to the *big storm for the southland Friday into Saturday, for you weather geeks, here is a technical discussion from the Weather Prediction Center back in MD.

 

CENTRAL TO SOUTHERN CALIFORNIA WIDESPREAD VERY HEAVY TO EXCESSIVE RAINFALL AMOUNTS ON TAP FOR THE CENTRAL TO SOUTHERN CALIFORNIA COASTAL REGION FRIDAY INTO SATURDAY

“THE AXIS OF ABOVE AVERAGE PW VALUES CURRENTLY SINKING SOUTHWARD THROUGH CENTRAL CALIFORNIA IS EXPECTED TO BECOME STATIONARY AT THE BEGINNING OF THIS FORECAST PERIOD IN RESPONSE TO THE AMPLIFYING UPSTREAM TROF APPROACH 140W AT 0000 UTC FRI. THIS ABOVE AVERAGE PW AXIS IS THEN EXPECTED TO REMAIN FOCUSED INTO THE CENTRAL TO SOUTHERN CALIFORNIA REGION WITH PW ANOMALIES OF 2-3+ STANDARD DEVIATIONS ABOVE THE MEAN IMPACTING THIS REGION THROUGH THE REMAINDER OF THE DAY 1 PERIOD AS THE AMPLIFYING UPSTREAM TROF APPROACHES THE SOUTHERN CALIFORNIA COAST. STRONG SOUTH SOUTHWESTERLY LOW LEVEL FLOW AHEAD OF THE AMPLIFYING TROF AND IN THE ANOMALOUS PW AXIS WILL PRODUCE ANOMALOUS MOISTURE FLUX VALUES OF 4-5+ STANDARD DEVIATION ABOVE THE MEAN—WITH THE SECOND HALF OF THE DAY 1 TIME PERIOD EXPECTED TO SEE THE GREATEST PRECIP IMPACT INTO THE CENTRAL TO SOUTHERN CALIFORNIA COAST RANGE FROM MONTEREY—SOUTHWARD TO THE TRANSVERSE RANGE OF SOUTHERN CALIFORNIA. AREAL AVERAGE PRECIP TOTALS OF 3-5″ POSSIBLE FROM THE CENTRAL TO SOUTHERN CALIFORNIA COAST RANGES—WITH ISOLATED MAXIMA UP TO 8” POSSIBLE. AWAY FROM THE MAX PRECIP AREA FROM MONTEREY TO THE TRANSVERSE RANGE—MODERATE TO LOCALLY HEAVY TOTALS LIKELY ACROSS MOST OF CENTRAL TO NORTHERN CALIFORNIA. WITH SUCH HEAVY RAINS EXPECTED TO IMPACT THESE AREAS—THERE WILL BE AN INCREASING RISK OF RUNOFF ISSUES—ESPECIALLY IN THE NUMEROUS BURN SCAR AREAS THROUGH THE TRANSVERSE RANGE”
