PLENTY OF MOISTURE ACROSS FA WITH DPS IN THE 70S. TREND SHOULD CONT

CAPES AROUND 2000-3000 J/KG. WOULD EXPECT TO SEE SIMILAR ATMOSPHERE
TODAY AS COMPARED TO THE PAST COUPLE OF DAYS. H85 WINDS ARE ONLY
AROUND 20KTS. DO NOT EXPECT ANY LARGE AREAS OF SVR WX WITH SUCH
MARGINAL SHEAR. WITH THAT IN MIND...A STORM OR TWO COULD APPROACH
SVR LEVELS WITH DAMAGING WINDS THE MAIN THREAT. PLAN ON BUMPING POPS
UP A BIT THIS MORNING WITH AMOUNT OF PRECIP WEST MVG ALONG FNT.

SITUATION AS HEAVY RAIN WL CONT TO BE POSSIBLE.

MOS TEMPS APPEAR A BIT COOL TODAY CONSIDERING SOME SUN IS EXPECTED.
