.DISCUSSION...
WATER VAPOR IMAGERY DEPICTS A MILDER REGIME OVER THE LOWER 48. A WSW
FLOW IS IN PLACE IN MID-UPPER LEVELS OVER THE SOUTHERN STATES IN
ADVANCE OF A POSITIVELY TILTED TROUGH OVER THE SOUTHERN ROCKIES.
FURTHER NORTH, ANOTHER TROUGH WAS DROPPING SOUTHEAST AND BECOMING
SIGNIFICANTLY SHEARED. AT THE SFC, A COLD FRONT WAS SITUATED FROM
SOUTHERN LM THRU ST. LOUIS AND ALONG THE I-44 AND INTO WEST CENTRAL
TX. THE FRONT ARRIVES TONIGHT AS A PORTION OF THE SHORTWAVE IN NM
RAPIDLY TRACKS EWD INTO THE OZARKS AND MID SOUTH. MID LEVEL
CONFLUENCE AND DEVELOPING SUBSIDENCE BEHIND THE FRONT ACT TO DRY THE
ATMOSPHERE QUITE A BIT AS THE FRONT TRACKS SOUTHEAST. HAVE LOWERED
POPS BACK TO SCHC.

THE SHEAR VORTICITY ZONE DROPS SE LATE SUNDAY BUT INTO A DRY ATMO
WITH CONFLUENCE IN MID-UPPER LEVELS REMAINING THRU MONDAY AS THE
UPPER LOW TRACKS FROM SOUTH TEXAS INTO NWRN GULF OF MEXICO. IT
APPEARS THIS SYSTEM WILL REMAIN TO OUR SOUTH. THE NEXT THREAT OF
RAIN STILL APPEARS TO BE ON TUESDAY NIGHT THRU WEDNESDAY NIGHT AS A
MORE AMPLIFIED NWRLY FLOW SHORTWAVE DROPS SOUTHEAST WITH A COLD
FRONT. NO SIGNIFICANT CHANGES WERE MADE IN THIS PORTION OF THE
FORECAST. THE GOOD NEWS IS THAT THIS AIRMASS WILL HAVE SOME PACIFIC
ORIGIN AS OPPOSED TO THE CP AIRMASSES WE HAVE SEEN AS OF LATE.
