Record Rain, Snow Brings A May Surprise To Southern Californians

Written by on May 15, 2015 in Spring 2015, United States of America with 0 Comments

While LA and San Diego have both dealt with record rainfall over the last 36 hours, it’s back to winter in the surrounding mountains, all thanks to an unusually late Alaska origin low  which has swept directly over Southern California.

Parts of San Diego were under water last night having recorded a 1.63 inches of rain. That’s the greatest amount for the date and month, breaking the previous May record of 1.49 inches set back in 1977. That 1.63 inches of rain is also more than San Diego would typically see in the entire May through October period.

Los Angeles also set a record with .16 of an inch of rain.

This view of a flooded San Diego last evening would be an impressive sight even in mid-winter but in mid May? Unprecedented!

The culprit to all this… a vigorous and unusually cold mid and upper level low.

An unseasonably cool day.

This system will push into the Plains over the next day or so, increasingly the severe weather potential. Looking for warming and drying out over California.

The CFSv2 weeklies try to bring warmer-than-normal back to California while the chilly Plains holds where rains have been unusually heavy and persistent. Will be interesting to see whether the chill makes it to the East Coast in response to the recurving west pacific typhoons.
