...well this just doesn't happen that often, so I had to post:
CA...
A VIGOROUS COLD UPPER-LOW WILL CONTINUE TO DIG SSEWD TODAY ALONG THE
COAST OF CA. A LARGE AREA OF MODERATE TO HEAVY RAIN IS ONGOING IN
THE LA BASIN ALONG THE FRONT AND AHEAD OF A BAND OF STRONG
LARGE-SCALE ASCENT. IN ADDITION...A WELL-DEFINED MID-LEVEL JET OF 90
KT IS CURRENTLY OFF THE COAST OF SRN CA. THIS FEATURE WILL CONTINUE
MOVING INLAND...PROVIDING STRONG ASCENT FAVORABLE FOR THUNDERSTORM
DEVELOPMENT THIS AFTERNOON. STORMS WILL BE MOST LIKELY IN THE BAND
OF MODERATE TO HEAVY RAIN AS THE BAND DRIFTS SWD ALONG THE COAST
TOWARD THE SAN DIEGO AREA THIS MORNING. OTHER STORMS WILL LIKELY
DEVELOP FARTHER NORTHWEST CLOSER TO THE UPPER-LOW WHERE THE
COMBINATION OF SFC HEATING AND COLD AIR ALOFT SHOULD BE MAXIMIZED.
IN ADDITION...A VORTICITY MAX EVIDENT ON WATER VAPOR IMAGERY WILL
MOVE SSEWD INTO THE LA BASIN THIS AFTERNOON. THIS COMBINED WITH
STRONG DEEP LAYER SHEAR WILL BE FAVORABLE FOR STRONG CONVECTION
WHICH MAY APPROACH SEVERE LIMITS. IF ENHANCED SFC HEATING OCCURS AND
SFC-BASED INSTABILITY CAN DEVELOP...A FEW MINI-SUPERCELLS WILL BE
POSSIBLE WITH A MARGINAL THREAT FOR WIND DAMAGE OR HAIL MAINLY ALONG
THE SRN CA COAST AND ACROSS THE SAN JOAQUIN VALLEY. A MINIMAL
TORNADO THREAT MAY ALSO DEVELOP IF SFC WINDS CAN RETURN TO THE
SOUTHEAST ACROSS THE LA BASIN CREATING A FAVORABLE SHEAR ENVIRONMENT
FOR LOW-LEVEL STORM ROTATION
Good thing I will be on the road for much of today out and about around the LA Basin. I will get pix if anything develops. If I could get a pic of a funnel cloud over LA... WOW!
