.DISCUSSION...

THIS EVE/TNGT:
ATMOSPHERE IS RECHARGING ITSELF AS SUN BEGINS TO BREAK OUT FROM
OVERNIGHT STORMS. DAY TIME HEATING WILL CREATE VERY UNSTABLE
CONDITIONS ACROSS MUCH OF CENTRAL AND SRN KS THIS AFTERNOON INTO THE
EVENING HRS. WATER VAPOR IMAGERY SHOWS NEXT SHORT WAVE CURRENTLY
MOVING E INTO TX PANHANDLE WHICH IS TRYING TO PHASE WITH WITH
NORTHERN STREAM TROUGH. THERE WILL BE A FAIRLY STRONG CAP IN PLACE
TRYING TO HOLD DOWN THE VERY UNSTABLE CONDITIONS...HOWEVER
APPROACHING SHORTWAVE SHOULD WEAKEN CAP ENOUGH FOR STORMS TO FIRE
LATER THIS EVE. OUTFLOW BOUNDARY FROM LAST NIGHT WAS IN CENTRAL OK
BUT SHOULD MIX NORTHWARD AS SFC LOW DEEPENS OVER TX PANHANDLE.

STORMS LOOK TO DEVELOP ALONG A WEAK BOUNDARY IN CENTRAL KS AND ALONG
OUTFLOW/SEMI WARM FRONT BOUNDARY MIXING NORTH IN S CENTRL KS. SHEAR
WILL INCREASE DURING THE EVENING HRS WHICH WILL CAUSE STORMS TO
BECOME MORE ORGANIZED WITH A FEW SUPERCELLS POSSIBLE. CANNOT TOTALLY
RULE OUT A ISOLATED TORNADO IN S CENTRAL GIVEN HIGH INSTABILITY AND
INCREASING SHEAR...EVEN WITH LCLS A BIT HIGH. SFC WINDS SHOULD BACK
SOME ACROSS S CENTRL KS WITH DEEPENING SFC LOW OVER THE TX
PANHANDLE. THE ACTIVITY LOOKS TO FORM A POSSIBLE MCS WHICH SHOULD
MOVE E/SE. MANY LOCATIONS SAW HEAVY RAIN LAST NIGHT...THEREFORE ANY
ADDITIONAL HEAVY RAIN WILL LIKELY CAUSE SOME FLOODING PROBLEMS SO
WILL ISSUE A FLOOD WATCH FOR MOST OF SRN/SERN KS WITH THIS IN MIND.

MON-MON NIGHT:
EXPECT MCS TO BE ONGOING IN ERN KS DURING THE MORNING HOURS, WITH
REST OF THE AREA CLEARING OUT.  UNSTABLE AIRMASS REMAINS IN PLACE
ACROSS THE AREA AS SUNSHINE RETURNS, SO WITH AFTN HEATING, ANOTHER
ROUND OF SHRA/TSRA ARE POSSIBLE BY MON AFTN INTO MON NIGHT.  NEXT IN
A SERIES OF S/WV MOVES INTO THE AREA BY MON AFTN,  WITH CAP LESS
THAN TDY EXPECT RAPID DVLPMNT OF CONVECTION.  WILL HAVE TO KEEP AN
EYE ON SVR AND FLOODING POTENTIAL TMRW, WITH TNGTS CONVECTION
PLAYING A ROLE IN THESE DECISIONS.

TUE:
FRONTAL BOUNDARY MAKES ITS WAY DOWN ACROSS THE PLAINS ON TUES
HELPING TO MOVE THE LOW LEVEL MOISTURE SOUTH OF THE AREA, AS DRIER
CANADIAN AIR MOVING ACROSS KS.  WILL KEEP LOW POPS ACROSS SRN HALF
OF KS, AS SOME POST FRONTAL SHRA ARE POSSIBLE. WILL ALSO KEEP TEMPS
BELOW CLIMO AS SHALLOW COOL AIR MOVE IN BEHIND THE FRONT. PREFER ETA
GUID NUMBERS FOR HIGHS

WED-THU:
SFC RIDGE AND NW FLOW MOVES ACROSS THE AREA FOR THE MIDWEEK HELPING
TO DRY US OUT FOR A COUPLE OF DAYS.  WILL MODERATE TEMPS WITH A
WARMING TREND EXPECTED BY THE END OF THE WEEK.

FRI-SUN:
RETURN SOUTHERLY FLOW WILL BRING MORE SUMMERLIKE TEMPS TO THE AREA
FOR THE START OF THE WEEKEND. MAIN MOISTURE ADVECTION WILL STAY WEST
OF THE AREA ON FRI, SO WILL KEEP POPS OUT OF THE AREA UNTIL FRI
NIGHT, WITH THE NOCTURNAL CONVECTION CHC RETURNING.  WILL INSERT
POPS FOR THE REST OF THE WEEKEND, AS WEAK S/WVS MOVE THROUGH THE
AREA WITH WEAK SFC BOUNDARY LOCATED ACROSS THE AREA.
