VALID 300725Z - 300830Z

THE THREAT OF SEVERE STORMS APPEARS TO BE DECREASING ACROSS THE
REGION AND WW 870 WILL BE ALLOWED TO EXPIRE AT 08Z.

AT 07Z...MESOANALYSIS INDICATED ARCTIC COLD FRONT FROM NEAR TYR TO
JUST N OF AUS TO NW DRT.  SUPERCELL WHICH HAD FORMED EARLIER THIS
EVENING HAS SINCE WEAKENED WITH REMNANT CONVECTION EXPECTED TO BE
UNDERCUT BY COLD FRONT NEAR AUS BY 08Z.

PRE-FRONTAL AIR MASS REMAINS MOIST AND RELATIVELY WARM EARLY THIS
MORNING HOWEVER RUC SOUNDINGS INDICATE THAT MID-LEVEL LAPSE RATES
ARE QUITE WEAK WHICH IS LIMITING THE DEGREE OF INSTABILITY.  WHILE
SOME THREAT OF ISOLATED SEVERE STORMS WILL EXIST AHEAD AND/OR ALONG
FRONT...THE MARGINAL INSTABILITY SHOULD PRECLUDE A MORE ORGANIZED
SEVERE THREAT.
