The rainy seasons big finale

Well, as all of you know living in California entails two distinct weather seasons, a dry season and a rainy season. April officially is the last full month of the rainy season in California with the season ending officially on May 15th and beginning once again on November 15th. Obviously with weather there is always exceptions and the rain doesn't "magically end" on the 15th but rather an approximate estimate would be the 15th of May. This year it seems the rainy season wants to give us a "Big Finale" with a large storm more typical of February taking aim at NorCal and then progressing south to SoCal. Beginning on Sunday(tomorrow) the weather will turn stormy with high winds/ heavy rain and maybe even some strong thunderstorms with large hail and damaging winds. This according to the latest forecasts from the models which show some instability with surface cape near 600 over the central valley and 400-500 over the coastal range of NorCal. Accompanying all this mess would be heavy snow in the Sierra Nevada above 4500ft with up to two feet of snow at or above the 7000ft level and one to two feet from 5000-7000ft. Rainfall totals should be exceptionally high for April with 1" rain totals for urban locations in the North Bay Area and 0.50-1" rain totals in other urban areas in NorCal and in SoCal with 2-3" rain totals in the mountains of NorCal below the snow line. Some selected cities rain total forecasts:

San Francisco(SFO): 0.80-0.90"
San Jose(SJC): 0.50-0.60"
Los Angeles(LAX): 0.40-0.50"
San Diego(SAN): 0.20-0.30"

As far as winds are concerned we should see some strong winds on the order of gusts to 50-55MPH with sustained winds near 30MPH for NorCal coastal and hill/mountain areas. Some selected NorCal cities for wind forecasts:

San Francisco(SFO): 50-55MPH
Oakland(OAK): 50-55MPH
San Jose(SJC): 35-45MPH

Tomorrow I'll update the forecast as well with regards to t-storm potential and if any other updates are needed. As is evident with the forecast though and this rainy season, it ain't over until the fat rain totals come in.
