WEAK WAVE DEVELOPING ON FRONT IN RESPONSE TO MID LVL S/W WILL CAUSE SHOWERS TO LINGER ACROSS CENTRAL AND SRN PORTIONS THROUGH MIDNIGHT.

LAPSE RATES EXPECTED TO BE VERY STEEP BY WED EVE UNDER UPR LOW WITH ISOLD/SCT TRW DEVELOPING. AIRMASS WILL BE COOL AND EXPECT HEALTHIER STORMS TO PRODUCE SMALL HAIL AND GUSTY WINDS. SLIGHT RISK OF SHOWERS CONTINUES INTO THU WITH COLD CYCLONIC FLOW ALOFT. .LONG TERM... THE SFC HIGH PRESSURE RIDGE WILL DOMINATE OUR WX FRIDAY AND PRODUCE MOSTLY CLEAR SKIES. THE HIGH WILL ALSO SET UP EXCELLENT RADIATIONAL COOLING CONDITIONS AND THERE IS SOME POTENTIAL FOR FROST DURING THE EARLY MORNING HOURS FRIDAY (ESPECIALLY NORTH AND NORTHEAST). LATEST MEDIUM RANGE GUIDANCE CONTINUES TO SUGGEST THAT A WEAK COLD FRONT WILL DROP IN FROM THE NORTH LATE SATURDAY AND SATURDAY NIGHT BRINGING A SLIGHT CHC OF SHOWERS AND PERHAPS A FEW TSTORMS. HOWEVER MOISTURE WITH THIS SYSTEM WILL BE QUITE LIMITED. DRY WX WILL RETURN SUNDAY INTO EARLY NEXT WEEK AS A SFC HIGH PRESSURE RIDGE TO OUR NORTH SUNDAY DROPS SOUTHEAST BUT REMAINS IN CONTROL OF OUR WX EARLY NEXT WEEK.
