...FORECAST CHALLENGE IS HOW HIGH TO GO WITH POPS THIS AFTN AND
TONIGHT...

SE EDGE OF WEAKENING MCS IS TRYING TO MOVE INTO NW PORTION OF LMK FA
(FORECAST AREA) AT 0730Z. MCS CONTINUES TO DIE AS IT MOVES OUT OF
SFC DPTS IN LOW TO MID 70S OVER SRN IL AND INTO MID 60S ACRS SW IND
AND NRN KY. MAY HAVE TO BREAK OFF NW COUNTIES TO ACCOUNT FOR ANY
LINGERING SHOWERS THIS MORNING OR COVER WITH NOWCASTS.

AM GOING TO ADD 20 TO 30 POPS OVER THE SOUTH FOR TODAY AS OUTFLOW
BOUNDARIES GENERATED BY CURRENT MCS TO OUR NW SHOULD BE LINGERING
OVER THE AREA THIS AFTN. WITH SFC DPTS PROGGED TO INCREASE IT SHOULD
BE MORE UNSTABLE ACRS THE AREA THAN FRIDAY SO CAN/T RULE OUT STORMS
POPPING IN ANY ONE AREA. PSUNNY SHOULD WORK WITH THINNING HIGH
CLOUDS FROM MCS OVER THE AREA.

CONVECTION WHICH DEVELOPED FURTHER WEST OVER CNTRL PLNS LAST NIGHT
SHOULD CREATE A CONVECTIVE VORT OR NEDDY EDDY THIS MORNING OVER MO
AND THIS FEATURE IS PICKED UP BY THE MODELS. THE ETA DEVELOPS THIS
FEATURE THE MOST AS IT MOVES ACROSS FA TONIGHT WITH NGM AND AVN
WEAKER AND MORE DISJOINTED. IND AND BNA FORECASTERS NOTED THAT THE
NGM MODEL ACTUALLY FORECAST CURRENT PRECIP PATTERN THE BEST SO HAVE
LEANED TOWARDS THIS MODEL.

INGREDIENTS SEEM TO BE SETTING UP FOR MCS DEVELOPING OVER E CNTRL MO
THIS EVENING WITH H85 WINDS INCREASING INTO THIS REGION AS THE DAY
PROGRESSES. MAIN QUESTION IS IF MCS DOES FORM TO OUR WEST...WHAT
WILL ITS MOVEMENT BE? H85-H30 THCKNS PATTERN POINTS TOWARDS AN E/SE
MOVEMENT WHILE H70 MEAN FLOW POINTS MORE TOWARDS A MORE E/NE
DIRECTION. WILL SPLIT THE DIFFERENCE AND GO WITH AN EASTERLY
MOVEMENT AND PLACE HIGHEST POPS OVER NW PORTION OF LMK FA. PW VALUES
INCREASE THIS EVENING AND THETA E RIDGE RUNS FROM E CENTRAL MO UP
THROUGH THE LOWER OHIO VALLEY WITH H85 TO H70 FLOW ALIGNED ALONG THE
THETA E RIDGE. THIS POINTS TOWARDS THE POSSIBILITY OF HEAVY RAINS
BUT AM GOING TO LEAVE OUT MENTION OF IT AT THIS TIME. HIGH WINDS
WILL ALSO BE A POSSIBLITY AHEAD OF LEADING STORMS AND THIS IS
RELECTED IN SLIGHT RISK OVER THE FA IN DAY 1 CONVECTIVE OUTLOOK.

THEN MODELS PUSH PRECIP OFF TO THE N AND E ON SUNDAY. HOWEVER...
WITH UNSTABLE AIR EXPECTED TO STILL BE IN PLACE AND LEFT OVER
BOUNDARIES LIKELY IN VICINITY...AM GOING TO LEAVE LOW POPS IN OVER
ENTIRE FA.

MAX TEMPS A BIT TRICKY WITH AT LEAST HIGH CLOUDS PROBABLY AROUND
BOTH TODAY AND SUNDAY BUT TEMPS AT LEAST IN THE 85 TO 90 RANGE A
GOOD BET.

THANKS FOR COORDINATION IND AND BNA.
