AN UPPER LEVEL LOW PRESSURE SYSTEM WILL MOVE SLOWLY EAST ACROSS THE OHIO VALLEY TODAY INTO SUNDAY. THIS WILL RESULT IN A CONTINUED CHANCE OF SHOWERS AND THUNDERSTORMS THROUGH THE WEEKEND. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... A WIDESPREAD AREA OF SHOWERS IS WORKING SLOWLY NORTH ACROSS WESTERN AND CENTRAL KENTUCKY UP INTO SOUTHERN INDIANA AND SOUTHWEST OHIO. THIS IS IN AN AREA OF GOOD LOW LEVEL CONVERGENCE ALONG THE NOSE OF A 25 TO 30 KNOT 850 JET PUSHING UP ACROSS THE TENNESSEE VALLEY. THE JET MAX IS FORECAST TO LIFT NORTH INTO OUR AREA BUT WEAKEN THROUGH LATE MORNING INTO EARLY AFTERNOON. AS A RESULT...EXPECT TO SEE PCPN CONTINUE TO PUSH UP INTO OUR AREA THROUGH MID MORNING BEFORE BEGINNING TO WEAKEN AS WE HEAD INTO THIS AFTERNOON. SOME MODEL UNCERTAINTY AS TO HOW MUCH WE WILL DESTABILIZE LATER THIS AFTERNOON AND AS A RESULT HOW MUCH REDEVELOPMENT WE MAY SEE.

BOTH THE GFS AND NAM ARE INDICATING ANOTHER LOW LEVEL JET DEVELOPING TONIGHT A LITTLE FARTHER EAST THAN THE ONE THIS MORNING...NOSING UP INTO SOUTH CENTRAL OHIO THROUGH DAYBREAK SUNDAY. THIS SHOULD LEAD TO THE BEST CHANCE FOR PCPN LATER TONIGHT ACROSS OUR EASTERN AREAS. SHOWERS AND THUNDERSTORMS WILL THEN CONTINUE INTO SUNDAY AS THE UPPER LEVEL LOW APPROACHES FROM THE WEST. GOOD SOUTHERLY FLOW OUT AHEAD OF THIS WILL KEEP THE PLUME OF MOISTURE ADVECTING UP INTO OUR AREA THROUGH SUNDAY...BUT THE AXIS OF HIGHEST PWS WILL SHIFT SLOWLY EAST OF OUR AREA THROUGH THE DAY. AS WE GET ON THE BACKSIDE OF THE UPPER LOW...WE SHOULD SEE DECREASING PCPN CHANCES SUNDAY NIGHT INTO MONDAY MORNING.

CONVECTIVE CHANCES APPEAR HIGHEST WITH AN INITIAL WAVE LATE MONDAY INTO TUESDAY...AND THEN AGAIN IN ADVANCE OF A COLD FRONT LATE WEDNESDAY INTO THURSDAY. HOWEVER...CONDITIONS APPEAR RATHER UNSETTLED DURING THIS ENTIRE TIME FRAME...GIVEN THE PRESENCE OF INSTABILITY AND THE EXPECTATIONS OF WEAK DISTURBANCES IN THE OVERALL ZONAL FLOW.
