Another Strong Atmospheric River takes aim upon the Central and Northern Sierra….Models are a bit higher again with freezing level Monday morning….thoughs in the lower elevations may need to take precautions once again….

Another major AR event is getting ready to move into the sierra later tonight with copious amounts of moisture….Monday seems to be the main day with the heaviest precipitation. The Snow level may rise to between 7500 to 8100 feet for a time, Monday AM.

Weather letter update tonight!    http://data.mammothweather.com/landing/

More later……

Storms still rolling into California one after another….Those in town concernd about the flood potential from the next AR event can relax a bit now…..But keep the shovels handy!

Mammoth Lakes picked up some 12 to 14 inches of snow today Friday with Mammoth Mt snow plot showing 15 inches at the main lodge at 4:00PM. Another 6 to 10 inches is expected tonight, between the Town and the Mountain by mid morning Saturday.

There will be some kind of a break in the weather Saturday afternoon into Sunday with just some snow showers. Highs will be in the 30s with lows in the 20s.  Another big storm is on the way for Mammoth late Sunday night. My current update shows that it is much less likely to bring rain in town as the models are coming in some 1 to 2 degrees colder with this storm now.  The snow level looks to be just above highway 395 and 203 Monday afternoon. This is certainly good news for those that are concerned about earlier forecasts of flooding in the low-lying areas of town as well as holiday travelers headed home concerned about the weather on highway 395 south.

I will have a brief update via my weather letter Saturday for the Sunday night through Wednesday storm,  Expect a more detailed forecast and outlook Monday AM and even a brief glimpse into the future for the week 2 possibly week 3 via the CFS.

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”
