AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TOPEKA KS
335 AM CDT WED JUL 21 2010

.DISCUSSION...

CONVECTION HAS CONTINUED TO DEVELOP OVERNIGHT FOCUSED NEAR A
925-850MB FRONT AIDED BY A 30 KNOT LOW LEVEL JET AND UPPER
DIVERGENCE NEAR THE FRONT. HEAVY RAIN AND LOCALIZED FLOODING
REMAINS THE PRIMARY CONCERN THIS MORNING. STRONG THUNDERSTORM
UPDRAFTS AND PRECIPITABLE WATER VALUES NEAR 2 INCHES HAS PRODUCED
HIGH RAINFALL RATES LEADING TO LOCALIZED AREAS OF FLOODING.

SURFACE LOW PRESSURE WILL DEEPEN IN WESTERN NEBRASKA TODAY IN
RESPONSE TO HEIGHT FALLS FROM AN UPPER TROUGH MOVING THROUGH THE
HIGH PLAINS. THE SURFACE FRONT WILL LIFT NORTH THROUGH NORTH
CENTRAL AND NORTHEAST KANSAS. ADDITIONAL THUNDERSTORM DEVELOPMENT
WILL BE POSSIBLE NEAR THE FRONT AS IT LIFTS NORTH.

NORTHEAST KANSAS WILL BE FIRMLY IN THE WARM SECTOR ON THURSDAY
AND FRIDAY. WITH THE FRONT TO THE NORTH...STRONG WARM AIR
ADVECTION WILL BRING HIGHS IN THE MID TO UPPER 90S AND DEWPOINTS
RANGING FROM THE LOWER 70S IN NORTH CENTRAL KANSAS TO THE MID AND
UPPER 70S IN EAST CENTRAL KANSAS. CONFIDENCE IS HIGH THAT HEAT
INDEX VALUES WILL REACH ADVISORY AND WARNING CRITERIA AND AFTER
COORDINATING WITH SURROUNDING OFFICES...HAVE POSTED HEADLINES.

A SHORTWAVE TROUGH ACROSS THE NORTHERN PLAINS WILL DRIVE A COLD
FRONT SOUTH INTO THE CENTRAL PLAINS FRIDAY. HEAT INDEX VALUES ARE
AGAIN EXPECTED TO REACH HEADLINE CRITERIA AND HAVE CARRIED
HEADLINES THROUGH FRIDAY. FORECAST MODEL CONSENSUS GRADUALLY
CARRIES THE FRONT THROUGH NORTHEAST KANSAS LATE FRIDAY AFTERNOON
INTO FRIDAY NIGHT BRINGING CHANCES FOR SHOWERS AND THUNDERSTORMS.
OVER THE WEEKEND THE FRONT IS PROGGED TO LIFT NORTH WITH
ADDITIONAL THUNDERSTORMS POSSIBLE.
