AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TOPEKA KS
319 PM CDT MON JUL 6 2015

.SHORT TERM...(THIS EVENING THROUGH TUESDAY)
ISSUED AT 307 PM CDT MON JUL 6 2015

ONGOING THUNDERSTORMS ARE LIKELY TO CONTINUE TO PUSH QUICKLY EAST
AND NORTHEAST AND ARE ALSO LIKELY TO GAIN INTENSITY THROUGH LATE
AFTERNOON INTO EARLY EVENING AS THEY MOVE INTO AN INCREASINGLY
UNSTABLE ENVIRONMENT. WIND SHEAR REMAINS MARGINAL FOR STORM
ORGANIZATION BUT COLD POOLS ARE ORGANIZING WELL AND SURGING EAST
WITH REPORTS TO 70 MPH ALREADY AND POCKETS OF 70 MPH OR STRONGER
LIKELY TO PERSIST WITHIN THE STRONGEST STORMS. VERY HEAVY RAINFALL
IS ALSO OCCURRING WITH THESE STORMS WITH REPORTS OF AT LEAST
TEMPORARY RATES OF 1.25 INCHES IN 30 MINUTES. THIS RAIN INTENSITY
IS ALSO LIKELY TO CONTINUE OR EVEN INTENSIFY WITH RAINFALL RATES
POTENTIALLY EXCEEDING 2 INCHES PER HOUR AT TIMES. THE NEAR TERM
FORECAST IS THE FOCUS OF THIS FORECAST PACKAGE AND WITH WARNINGS
ONGOING, WILL FOCUS THE DISCUSSION ON THIS PERIOD.

STORMS ARE LIKELY TO QUICKLY PUSH SOUTHEAST GIVEN THE COLD POOL
ORGANIZATION AND PUSH OUT OF EAST CENTRAL KANSAS BY MID EVENING.
WHILE SOME REDEVELOPMENT IS POSSIBLE IN AN ELEVATED NATURE BEHIND
THE FRONT OVERNIGHT DO NOT EXPECT THE SEVERE THREAT TO CONTINUE
MUCH BEYOND THE INITIAL SEVERE LINE. HOWEVER...THE HEAVY RAIN
POTENTIAL WILL CONTINUE INTO THE OVERNIGHT HOURS MAINLY IN EAST
CENTRAL KANSAS...MAINLY FOCUSED IN THE FLASH FLOOD WATCH AREA.

.LONG TERM...(TUESDAY NIGHT THROUGH MONDAY)
ISSUED AT 307 PM CDT MON JUL 6 2015

THE MID AND LONG TERM PERIOD HAS CHANGED LITTLE IN TERMS OF THE
FORECAST. HAVE MAINTAINED THE LONG-LIVED FLASH FLOOD WATCH
ALTHOUGH WITH LOWER END CONFIDENCE BEYOND TONIGHT. HOWEVER... IT
APPEARS LIKELY THAT ONE OR MORE ROUNDS OF HEAVY RAIN WILL MOVE
THROUGH THE AREA WITH THE BEST CHANCE FOR THESE IN EAST CENTRAL
KANSAS COUNTIES. THE GFS IS THE DRY OUTLIER OF THE MODEL SUITE
WITH THE TREND BEING SOUTH OF THE AREA WITH THE HEAVIEST
PRECIPITATION BUT OTHER GUIDANCE IS PERSISTENT ENOUGH WITH
BRINGING HEAVY RAIN INTO THE AREA THAT IT WARRANTS WATCH
CONTINUATION.

THE LONG TERM FORECAST LOOKS TO DRY OUT AND HEAT UP AS AN UPPER
RIDGE GRADUALLY BUILDS INTO THE AREA.
