IMPRESSIVE COUPLED 850/250 MB DIVERGENCE WILL CROSS CWA BETWEEN 21Z AND 05Z...COUPLED WITH EQUALLY IMPRESSIVE LOW LEVEL CONVERGENCE WILL YIELD SIGNIFICANT UVV/S. THERMODYNAMIC FORCING ALSO IMPRESSIVE WITH SHARP LOW LEVEL THETA-E RIDGE CROSSING CWA IN CONCERT WITH DYNAMIC FORCING. PLENTY OF INSTABILITY AVAILABLE AS WELL WITH MODIFIED 12Z DTX SOUNDING YIELDING CAPES IN 3 TO 4 KJ/KG RANGE. WITH WET BULB ZERO HEIGHTS RUNNING AROUND 12K FEET...MAIN THREAT LOOKS TO BE WIND AS NEAR UNIDIRECTIONAL WIND SPEED THROUGH THE COLUMN WITH MAX WINDS IN THE 35 TO 40 KNOT RANGE. WILL ALSO MONITOR RAINFALL. PWS EQUAL OR SLIGHTLY EXCEED 2 INCHES COINCIDENT WITH BEST LIFT. INDIVIDUAL STORMS HAVE BEEN MOVING AT NORTH AT 30 MPH. HOWEVER...LINE OF STORMS MOVING ONLY AT ABOUT 15 MPH. SO SOME AREAS COULD RECEIVE A GOOD DOUSING. DEEP MOISTURE AND LIFT WILL EXIT BETWEEN 10 PM AND 2 AM...WEST TO EAST...AND WITH IT THREAT OF SHRA AND TSRA. STRONG DNVA SETS IN DURING THE OVERNIGHT HOURS...LEADING TO CLEARING SKIES. BROAD SURFACE TROUGH SWINGS ACROSS CWA DURING THE DAY ON SATURDAY. BUT...WITH PLENTY OF DRY AIR IN PLACE...AND SURFACE RIDGE BUILDING IN WILL PRECLUDE ANYTHING MORE THAN SOME CIRRUS ACROSS THE NORTH AND CU EVERYWHERE /LOOKS TO BE NO MORE THAN SCT/. A POSSIBLE FLY IN THE OINTMENT FOR SATURDAY NIGHT IN THE SOUTHERN CWA. BOTH ETA AND AVN INDICATE AREA OF MODEST 850 THETA-E ADVECTION ACROSS SOUTHERN PART OF CWA.
