.DISCUSSION...

CONVECTION IS INTENSIFING FROM YNG TO NEAR CMH THIS AFTERNOON WITH
CAPES AROUND 1000 J/KG WHICH IS MUCH HIGHER THAN MODEL GUIDANCE OF
EITHER THE RUC/ETA OR GFS RUNS. SPC SUPERCELL PARAMETER HAS INCR TO
ABOUT 1 NEAR KNOX COUNTY WHICH MEANS CONDITIONS ARE BECOMING
FAVORABLE FOR SUPERCELL DEVELOPMENT. SFC WINDS ARE BACKING IN
ADVANCE OF THE SFC LOW PRESSURE WAVE THAT IS MOVING NE TOWARD THE
REGION. THIS WILL INCREASE LOW LEVEL HELICITY AND AID IN STORM
ROTATION AND INCREASE THE LIKELYHOOD OF DAMAGING WINDS AND LARGE
HAIL. BUFKIT SOUNDINGS OVER THE THREAT AREA SHOWS THE SFC DELTA
THEATA-E TO BE AROUND 15C LATE THIS AFTERNOON WHICH SHOULD AID IN
DOWNBURST POTENTIAL OF STORMS. THE MAIN THREAT AREA CONTINUES TO BE
FROM SOUTHEAST CRAWFORD PA SOUTHWEST THROUGH YNG AND TO KNOX COUNTY.
THE THREAT WILL PERSIST UNTIL THE SFC WAVE MOVE NE OF THE REGION
PERHAPS AROUND 02 UTC. THERE IS SOME CONCERN ABOUT FLOODING AS
RAINFALL AMOUNTS OF 1 TO 2 INCHES ARE POSSIBLE IN THE HEAVIER
DOWNPOURS.

THE SURFACE LOW WILL TRACK NE OF THE REGION SUNDAY AS COOLER AND
MORE STABLE AIR OVERSPREADS THE REGION. BOTH THE ETA AND GFS ARE
SLOWER THAN YESTERDAYS RUN IN MOVING THE SHORT WAVE EAST OF THE
REGION. CONSEQUENTLY...THE PCPN WILL LINGER TO PERHAPS MIDDAY NOW
ACROSS MOST OF THE AREA. GRADUAL CLEARING WILL PROGRESS EWD SUNDAY
AFTERNOON.  COOL HIGH PRESSURE WILL BUILD INTO THE REGION MONDAY SO
THERE IS SOME CONCERN ABOUT FROST.
