0246 PM CDT THU OCT 30 2008
VALID 302000Z - 311200Z
...NO SVR TSTM AREAS FORECAST...
...MID/LWR MO VLY...
COMPACT SHORTWAVE TROUGH HAS BEGUN TO DIG SSEWD AND WILL REACH THE
NRN OZARK REGION BY 12Z/31. VIGOROUS ASCENT ASSOCD WITH THIS SYSTEM
WAS CONTRIBUTING TO MOISTENING OF THE MID-TROPOSPHERE LEADING TO
WEAK CAPE. SPORADIC TSTMS WILL LIKELY CONTINUE TO DEVELOP ALONG THE
TRACK OF THE VORT MAX FROM ERN NEB SEWD INTO ERN KS/WRN MO INTO
FRIDAY MORNING.
...CSTL CNTRL CA INCLUDING THE BAY AREA...
TSTMS 75-100 NM WSW-SW OF KSFO WERE ASSOCD WITH A WEAKENING
SHORTWAVE TROUGH MOVING THROUGH THE ERN PAC BASIN LONGWAVE TROUGH.
THE IMPULSE WILL TRAVEL TO THE CNTRL CA CST BY 00Z/31 WITH A
SECONDARY DISTURBANCE QUICKLY FOLLOWING ON ITS HEELS. EXPECT CSTL
TSTMS MAY CLIP PARTS OF THE CSTL REGION INCLUDING THE BAY AREA
THROUGH EARLY EVENING AND PERHAPS AGAIN LATER AT NIGHT. HIGHEST
PROBABILITIES SHOULD REMAIN OFFSHORE.
...SE AZ MOUNTAINS...
PWAT HAS INCREASED OVER THE PAST 24-HRS AND VSBL SATL INDICATES
CONSIDERABLE TCU/CU OVER THE MOUNTAINS NEAR/E OF KTUS. WEAK
SUBTROPICAL IMPULSE MOVING NWD INTO SRN AZ MAY BE SUFFICIENT TO
SUPPORT ISOLD DEEPER CONVECTION/TSTMS THROUGH EARLY EVENING.
