LATEST RADAR TRENDS SUGGEST FORCED LINE OF CONVECTION CONTINUES TO
SLOWLY DEEPEN AND INTENSIFY FROM CNTRL MO INTO NWRN AR.  ISOLATED
THUNDERSTORMS ARE NOTED ALONG THIS LINE DESPITE THE MEAGER
INSTABILITY NOTED ON 00Z SOUNDINGS AND DIAGNOSTIC FIELDS...ON THE
ORDER OF 100-200J/KG.  IT APPEARS UPDRAFTS MAY ACTUALLY BE ROOTED
JUST ABOVE THE SFC THUS ANY TRANSFER OF STRONGER WINDS ALOFT COULD
BE HAMPERED DUE TO MORE STABLE BOUNDARY LAYER. AT ANY RATE...SQUALL
LINE WILL PROGRESS ACROSS THE REMAINDER OF SERN MO AND NRN AR BEFORE
SLOWLY WEAKENING EAST OF THE MS RIVER WHERE INSTABILITY IS HARDLY
SUPPORTIVE OF STRONG UPDRAFTS.

...GULF COAST...

SHALLOW CONVECTION HAS STRUGGLED BENEATH RESTRICTIVE LAYER OF
INHIBITION AT MID LEVELS OVER SERN TX THIS EVENING.  OVER THE LAST
HALF HOUR A FEW UPDRAFTS HAVE INTENSIFIED AND PRODUCED LIGHTNING
NEAR CLL...NW OF HOUSTON.  THIS ACTIVITY SHOULD CONTINUE ALONG THE
FRONT AND MAY AT TIMES GENERATE A FEW LIGHTNING STRIKES BEFORE
DISSIPATING CLOSER TO THE LA BORDER.

FARTHER EAST...SUSTAINED WARM ADVECTION WILL MAINTAIN CONVECTIVE
THREAT MUCH OF THE NIGHT WITHIN MOIST FEED OFF THE NRN GULF OF
MEXICO.  MUCH OF THIS ACTIVITY WILL REMAIN OFFSHORE DUE TO WEAK
INSTABILITY.
