Area forecast discussion, Jul 19, 12:48 AM CDT, 17 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO
1248 AM CDT WED JUL 18 2001

...MAIN CONCERNS ARE THUNDERSTORMS OVER NORTHERN CWA THIS MORNING
AND TONIGHT AND OF COURSE THE HEAT AND HUMIDITY...

AREA OF STRONG CONVECTION CONTINUE TO MOVE ACROSS NORTHERN CWA AT
05Z WITH ADDITIONAL STORMS DEVELOPING OVER NORTH CENTRAL KANSAS.
LLJ CRANKING TO 30 TO 35 KNOTS OVER EASTERN KS HELPING SUPPORT
FURTHER DEVELOPMENT.  MODELS SHOWING WIDELY VARYING SOLUTIONS
TONIGHT WITH MESO ETA INDICATING NO PRECIP DEVELOPING UNTIL AFTER
09Z...AVN HAS ALL PRECIP OVER NORTHEAST CWA AND NGM ONLY MODEL WITH
PRECIP WHERE IT IS CURRENTLY AT.  MESO-ETA THEN PUSHES A FAIRLY
STRONG BOUNDARY BACK TO THE WEST...INTO CENTRAL NE THROUGH 12Z
...KEEPING PRECIP IN CWA ALL MORNING.  WHILE THIS A LITTLE UNUSUAL I
THINK THE GENERAL TREND OF CONTINUED DEVELOPMENT TO OUR WEST IS A
LIKELY SCENARIO. CORFIDI VECTORS SUGGEST THAT MOVEMENT SHOULD BECOME
MORE SOUTHERLY AS TIME GOES ON SO WILL WATCH FOR THIS TREND TO
DEVELOP.  THUS FAR MAINLY AN EASTERLY MOVEMENT. POPS FOR TODAY WILL
BE DECIDED NEAR ISSUANCE TIME.

IF THUNDERSTORMS DO BUILD SOUTH HEAT ADVISORY FOR ALL BUT SOUTHWEST
CWA MAY BE IN DANGER.  NORTHEAST CWA DID NOT MEET THIS CRITERIA
YESTERDAY AND LIKELY WILL NOT TODAY SO WILL LEAVE THEM OUT OF ANY
ADVISORY TODAY.  WILL MAKE DECISION ON HEAT WARNING FOR SOUTHWEST
TWO THIRDS OF CWA AS THUNDERSTORM PICTURE UNFOLDS. AGAIN...WITH SUCH
HIGH DEW POINTS WE ONLY NEED A TEMPERATURE OF AROUND 90 TO PUSH THE
HEAT INDEX ABOVE 105 SO A BIT OF A DIFFICULT CALL IF CLOUDS WILL BE
AROUND ALL MORNING.

CANNOT TAKE POPS OUT OF NORTHERN HALF OF CWA TONIGHT AS BOUNDARY
INTERACTIONS AND LLJ WILL LIKELY LEAD TO ADDITIONAL DEVELOPMENT
TONIGHT. SOUTHWEST CWA STILL REMAINS LEAST LIKELY TO SEE ORGANIZED
CONVECTION AND WILL PROBABLY LEAVE A SILENT 20 IN THERE.

FOR FRIDAY...MORE HEAT AND HUMIDITY BUT CLOUDS AND PRECIP LIKELY TO
MAKE DECISION TOUGH.  WILL PROBABLY GO WITH A HEAT WARNING OVER THE
SOUTHWEST THIRD OF CWA IF ONE IS ISSUED FOR TODAY.

WILL MAKE NO CHANGES TO THE EXTENDED.
