DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1026 AM CST FRI NOV 09 2007
VALID 091630Z - 101200Z
..NO TSTM AREAS FORECAST...
..SYNOPSIS/DISCUSSION...
A STRONG UPPER VORTICITY MAX ON CYCLONIC SIDE OF JET WILL DIG SEWD
OUT OF THE UPPER MS VALLEY...MOVING RAPIDLY INTO THE CAROLINAS BY
SAT MORNING. UPPER COOLING AND LIFT ASSOCIATED WITH THIS TROUGH MAY
ALLOW FOR AN ISOLATED LIGHTNING STRIKE FROM WI SEWD INTO THE
CAROLINAS...BUT INSTABILITY WILL REMAIN QUITE LIMITED AND WILL
MAINTAIN LESS THAN 10% PROBABILITY OF THUNDER.
UPPER RIDGING WILL TAKE PLACE ACROSS THE CNTRL STATES...WITH SOME
LOW LEVEL MOISTURE RETURNING NWD INTO TX/LA. SOME DAYTIME HEATING
WILL RESULT IN DIURNAL CONVECTION OVER SE TX AND WRN
LA...HOWEVER...RELATIVELY SHALLOW MOISTURE DEPTH AS WELL AS POOR
LAPSE RATES ALOFT SHOULD RESULT IN LITTLE IF ANY DEEP
CONVECTION/THUNDER.
ELSEWHERE...A COMPACT UPPER LOW WILL DRIFT EWD INTO CNTRL CA TODAY
BUT LACK OF ANY SUBSTANTIAL INSTABILITY SHOULD PRECLUDE ANY
WIDESPREAD THREAT OF THUNDER.
