CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 091822Z - 092015Z

...THERE IS A POTENTIAL FOR SOME STRONG/SEVERE STORMS ACROSS THE
INTERIOR NRN/CNTRL CA VALLEYS THIS AFTN...

LATEST WATER VAPOR IMAGERY SHOW UPPER LOW NOW OVER EXTREME NRN CA
NEAR THE ORE BORDER...WITH STRONG DIFFLUENCE REGION SPREADING ACROSS
THE GREAT BASIN. AT THE LOWER LEVELS...AIRMASS IS BECOMING
INCREASINGLY UNSTABLE WITH SBCAPE VALUES APPROACHING 1000 J/KG. VAD
WIND DATA FROM SACRAMENTO SUGGESTS AROUND 25-30 KT OF DEEP LAYER
SHEAR WHICH IS SUFFICIENT FOR ORGANIZED MULTICELL TSTMS. THE STEEP
LAPSE RATE ENVIRONMENT ASSOCIATED WITH VERY COLD TEMPS ALOFT COUPLED
WITH MODERATE VERTICAL SHEAR WILL SUPPORT LARGE HAIL IN ADDITION TO
GUSTY TSTM WINDS WITH THE STRONGEST STORMS. ALTHOUGH BRIEF LOW LEVEL
ROTATION OR BRIEF FUNNEL CLOUDS ARE POSSIBLE...THE MAIN THREAT WITH
STORMS WILL BE FROM STRONG WINDS AND HAIL.
