AS THE DRY SLOT KICKS INTO THIS AIRMASS...EXPECT THE MCS TO OUR WEST TO CONTINUE AND PERHAPS EVEN INTENSITY A LITTLE. HAVE INCREASED POPS TO CATEGORICAL AHEAD OF THE MCS...FOLLOWING FAIRLY CLOSE TO THE 0600 ETA/S H7 OMEGA FIELD AS A GUIDE.

UPPER LEVEL FORCING WILL INCREASE THROUGHOUT THE DAY...WITH FAVORABLE UPPER DIVERGENCE EXPECTED AFTER 18Z...AND THEN 850 TO 500 MB DPVA ARRIVES TOWARD 00Z AS THE MIDWEST CLOSED LOW BEGINS TO OPEN AND PHASE IN. SURFACE DEWPOINTS BEGIN THE DAY IN THE 50S...WITH A GRADUAL INCREASE EXPECTED AS SW FLOW IMPROVES. WARM SECTOR CONVECTION SHOULD THUS INCREASE THROUGH THE DAY AS CAPES REACH 1000+ J/KG WITH LI OF MINUS 2 OR BETTER.

MOISTURE AND PRECIPITATION AHEAD OF THIS NEXT DIGGING SYSTEM IS SLATED MAINLY FOR TUESDAY...BUT TIMING CONCERNS WILL REQUIRE STRETCHING CHC POPS INTO WED PER PREVIOUS FORECAST. TEMPERATURES WILL SLOWLY REBOUND THROUGH THE LATE WEEK AS A SOUTHEAST RIDGE RECOVERS. AVIATION... PERIODS OF IFR FOG WILL CONTINUE AT KAVL UNTIL SUNRISE.
