CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY

VALID 072211Z - 072315Z

ISOLATED STORMS HAVE DEVELOPED S OF WW 62 ALONG THE ADVANCING FRONT.
WITH CAPPING LIKELY TO LIMIT THUNDERSTORM COVERAGE HOWEVER...WW
APPEARS UNLIKELY ATTM.

LATEST SURFACE ANALYSIS SHOW FRONT ADVANCING SEWD ACROSS SERN
PORTIONS OF TX...INTO AIRMASS FEATURING LOW TO MID 60S DEWPOINTS AND
AROUND 1000 J/KG MIXED-LAYER CAPE. MODEL SOUNDINGS DEPICT AN
INCREASINGLY CAPPED BOUNDARY LAYER WITH SWD EXTENT ALONG THE
FRONT...BUT ISOLATED STORMS -- CAPABLE OF PRODUCING GUSTY WINDS AND
HAIL -- HAVE MANAGED TO DEVELOP AS FAR S AS WALKER CO.

ADDITIONAL DEVELOPMENT SWD ALONG THE FRONT IS QUESTIONABLE DUE TO
THE AFOREMENTIONED CAPPING...BUT GIVEN DEGREE OF INSTABILITY AND
SHEAR ANY STORM WHICH CAN BREACH THE CAP WOULD POSE A SEVERE THREAT.
ATTM...CONTINUE TO BELIEVE THAT ANY ADDITIONAL
FRONTAL/SURFACE-BASED DEVELOPMENT WILL REMAIN SUFFICIENTLY ISOLATED
AS TO PRECLUDE ADDITIONAL WW ISSUANCE.

I like that cross section of a severe thunderstorm even better, wxdata. Did you get it from the same place where you told me how to tell how tall that a thunderstorm is? By the way, if I am not mistaken I do believe that I saw a small magenta blob in there which I do believe indicates hailstones.

Wed Apr 07, 2010 6:21 pm

Wind shift to NW at my location now.
