.SHORT TERM /TONIGHT THROUGH MONDAY NIGHT/...
COLD FRONT SWEEPING ACROSS THE STATE THIS AFTERNOON WILL CONTINUE
PUSHING EAST THIS EVENING...SHOULD BE THROUGH THE FORECAST AREA BY
06Z WITH DEEPER CONVECTION ENDING DURING THE EVENING. PERSISTENT
UPPER LOW OVER THE OHIO VALLEY THROUGH THE SHORT TERM FORECAST PERIOD

THROUGH THIS TIME PERIOD. ONLY INCLUDING THUNDER DURING THE DAY
MONDAY WITH THE INCREASED UPPER FORCING.

.LONG TERM /TUESDAY THROUGH SATURDAY/...
NO CHANGES TO THE EXTENDED FORECAST TRENDS AT THIS TIME. STILL SOME
DISAGREEMENT BETWEEN THE GFS AND ECMWF CONCERNING THE EVOLUTION OF
THE UPPER FLOW...BUT GENERALLY DRY AND MILD TO SEASONALLY WARM
TEMPERATURES LOOK APPROPRIATE WITH THE OMEGA-LIKE STATIC UPPER
PATTERN PERSISTING THROUGH THE MAJORITY OF THE PERIOD.
