.DISCUSSION...

EARLY MORNING CONVECTION TO OUR NORTH AND WEST HAS KICKED OFF
SEVERAL OUTFLOW BOUNDARIES IN THE AREA...WITH THE MAIN ONE RUNNING
FROM SENECA SOUTHWEST TO MORRIS COUNTY ATTM. THIS HAS TRIGGERED A
FEW STORMS UP NORTH...NEARER TO THE SFC FRONT AND THE NOSE OF THE
LLJ. STORMS ALSO CONTINUE SOUTH OF THE CWA IN SOUTHEAST KANSAS
ASSOCIATED WITH SHORTWAVE THERE MOVING NORTHEAST.

TODAY...THINK AT THIS TIME THAT THE FRONT WILL STAY NORTH OF THE
AREA TODAY...RESULTING IN ANOTHER DAY OF HOT TEMPERATURES.
INCREASED MAX TEMPS A BIT. WILL KEEP AN ISOLD POP IN THE MORNING
HOURS DUE TO OUTFLOWS...THEN HAVE KEPT ISOLD/SCT POPS IN THE
AFTERNOON AS DESTABILIAZTION OCCURS. DAYTIME STORMS THAT FORM IN
STRONG HEATING WILL HAVE POTENTIAL TO BRING STRONG WINDS.

TONIGHT...MAIN FRONT RELIES UPON SEVERAL SHORTWAVES TO MOVE
SOUTHEAST DOWN THE UPPER RIDGE AND PUSH THE BOUNDARY INTO THE
STATE. LOOKING AT WV IMAGERY AND MODEL DATA...IT APPEARS THE
MODELS COULD BE A BIT FAST WITH THE FRONTS PROGRESS CONSIDERING
DISTANCE OF UPPER SYSTEMS AT THIS TIME. WILL HOLD OFF ON BRINGING
FRONT IN UNTIL THE EVENING AND OVERNIGHT HOURS. APPEARS THAT LLJ
WILL THEN HELP KEEP STORMS GOING AND HAVE INCREASED POPS MOST
AREAS IN THE 6-12Z TIMEFRAME. PWS POOL TOWARD THE 2 INCH
RANGE...SO LOCALLY HEAVY RAINFALL IS POSSIBLE IN ADDITION TO
STRONG WINDS.

FRIDAY-WED...FRONT PUSHES SOUTHWARD ON FRIDAY...THEN SHIFTS EAST AND
LEAVES THE AREA IN SOUTHERLY FLOW FOR SUNDAY INTO MONDAY. HAVE
KEPT HIGHS IN THE 90S WHICH IS STILL ABOVE NORMAL. NEXT SYSTEM
PROGGED BY GFS TO MOVE IN ON MONDAY...THEN KEEP TEMPS NEAR NORMAL
THROUGH WEDNESDAY AS UPPER FLOW BECOMES SOUTHWESTERLY. NO CHANGES
BEYOND SUNDAY. 67
