AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TOPEKA KS
322 PM CDT THU AUG 18 2005

.DISCUSSION...

TONIGHT AND FRIDAY...WATER VAPOR AND PROFILERS SHOWING A WEAK
SHORTWAVE LIFTING EAST NORTHEAST ACROSS SOUTHEAST CO/SOUTHWEST KS
WHICH WILL MOVE EAST ACROSS THE AREA THROUGH THIS EVENING. VISIBLE
SHOWING CU FIELD BENEATH STRONG CAP CONTINUES ACROSS THE FAR
NORTHERN CWA WHERE 850 CONVERGENCE PERSISTS. WITH 850 WAA INCREASING
THIS EVENING WITH THE APPROACH OF THE SHORTWAVE AND MOISTURE
CONVERGENCE ACTUALLY FCST TO INCREASE NORTHEAST TO SOUTHWEST...WILL
KEEP A SLIGHT CHANCE FOR THUNDERSTORMS DURING THE EVENING. ANY
CONVECTION THAT FORMS WOULD LIKELY BE ELEVATED OVER THE SOUTH BUT
ANY SFC BASED CONVECTION NEAR CONVERGENCE ZONE OVER THE NORTH THAT
COULD MANAGE TO BREAK THE CAP WOULD LIKELY BECOME SEVERE WITH CAPES
COMMONLY 3000-3500. WITH UNCERTAINLY ON THE ABILITY OF THE
CONVECTION TO FORM WILL ONLY GO WITH A SLIGHT CHANCE POPS THROUGH
THE EVENING...THEN DRY ON THROUGH SUNRISE. WITH DEWPOINTS STAYING UP
TONIGHT...ESPECIALLY SOUTHEAST HALF...WILL KEEP LOWS TONIGHT THERE
IN THE MID 70S WITH LOW 70S FURTHER BACK IN NORTHCENTRAL. COLD FRONT
STILL FCST TO ENTER THE NORTHERN CWA LATE FRIDAY AFTERNOON....CLOSER
TO THE ETA FCST. ALTHOUGH THE MORNING ACROSS THE CWA SHOULD BE
DRY...A FEW ISOLD THUNDERSTORMS COULD DEVELOP OUT AHEAD OF THE FRONT
IN THE EASTCENTRAL...ALTHOUGH A MUCH BETTER CHANCE FOR THUNDERSTORMS
TO FORM BY LATE AFTERNOON APPEARS ALONG THE FRONT OVER THE NORTHERN
PORTIONS OF THE CWA. WITH HIGH CAPES AND BETTER SHEAR PARAMETERS IN
PLACE...COULD SEE ADDITIONAL SEVERE THREAT BY LATE IN THE DAY NORTH
WITH A HAIL AND WIND THREAT. ALTHOUGH THERE SHOULD BE MORE CLOUDS
AROUND THE CWA...ESPECIALLY IN THE AFTERNOON...MODELS INDICATING THE
850 THERMAL AXIS WILL BE IN PLACE AHEAD OF THE FRONT FROM THE
SOUTHWEST TO NORTHEAST DURING MUCH OF THE AFTERNOON. THIS WILL ALLOW
FOR HIGHS TO REACH THE 95 TO 100 DEGREE RANGE BEFORE CONVECTION
DEVELOPS.

FRIDAY NIGHT AND SATURDAY...EVEN THOUGH THE NAM IS A BIT FASTER THAN
THE GFS IN MOVING THE FRONT SOUTH INTO THE CWA LATE FRIDAY
AFTERNOON...BOTH THE NAM AND GFS MOVE THE FRONT THROUGH THE ENTIRE
CWA LATE FRIDAY NIGHT AND EARLY SATURDAY MORNING. SCATTERED TO
NUMEROUS SHOWERS AND THUNDERSTORMS SHOULD DEVELOP ALONG THE FRONT
FRIDAY EVENING ACROSS THE NORTHERN AND CENTRAL COUNTIES AND MOVE
SOUTH THROUGH THE NIGHT. GIVEN AN ENVIRONMENT...WITH IN THE WARM
SECTOR...FRIDAY EVENING WITH MODERATE VERTICAL WIND SHEAR AND CAPES
OF 2000-4000 J/KG...SOME OF THE THUNDERSTORMS THAT DEVELOP ALONG AND
AHEAD OF THE FRONT MAY BECOME SEVERE WITH LARGE HAIL AND DAMAGING
WINDS BEING THE PRIMARY HAZARD. THE INTENSITY OF THE THUNDERSTORMS
SHOULD DECREASE AFTER SUNSET AS WE LOOSE THE DAYTIME HEATING. EVEN
THOUGH THE FRONT WILL MOVE SOUTH THROUGH THE CWA LATE FRIDAY NIGHT
AND EARLY SATURDAY MORNING...THE SHOWERS AND THUNDERSTORMS SHOULD
CONTINUE THROUGH MOST OF NIGHT AND EARLY MORNING HOURS OF SATURDAY
NORTH OF THE FRONTAL BOUNDARY DUE TO ISENTROPIC LIFT/WAA. THERE IS
ALSO THE POTENTIAL FOR HEAVY RAINFALL ACROSS THE EASTERN CWA FRIDAY
NIGHT. EVENTUALLY THE DEEPER COOLER AND DRIER AIR MASS WILL ADVECT
SOUTH ACROSS THE CWA DURING THE DAY ON SATURDAY AND BRING AN END TO
THE RAIN CHANCES FROM NORTH TO SOUTH DURING THE LATE MORNING AND
EARLY AFTERNOON HOURS OF SATURDAY. LOWS FRIDAY NIGHT WILL BE IN THE
LOWER 70S. HIGHS ON SATURDAY WILL BE IN THE MID 80S...THOUGH IF THE
CLOUDS AND RAIN CONTINUE THROUGH SATURDAY AFTERNOON HIGH
TEMPERATURES WILL BE COOLER.

SUNDAY THROUGH THURSDAY...A SURFACE RIDGE OF HIGH PRESSURE WILL
EXTEND FROM THE UPPER MS RIVER VALLEY SOUTHWEST INTO NORTH TX. AN
UPPER LEVEL RIDGE OVER THE WESTERN CONUS WILL SLOWLY EXPAND EAST
ACROSS THE PLAINS STATES NEXT WEEK. EXPECT DRY CONDITIONS WITH HIGH
TEMPERATURES IN THE LOWER TO MID 80S SUNDAY...WARMING INTO THE LOWER
90S BY THURSDAY AS THE 5H RIDGE ALOFT EXPANDS EAST. THE DEEPER GULF
MOISTURE WILL BEGIN TO RETURN NORTH TOWARDS KS BY MID WEEK..HOWEVER
WITH THE 5H RIDGE OVER THE PLAINS THE ONLY THUNDERSTORM DEVELOPMENT
WILL BE DUE TO UPSLOPE FLOW ACROSS THE HIGHER TERRAIN OF THE WESTERN
HIGH PLAINS. THE UPPER LEVEL WINDS ARE FORECASTED TO BE WEAK...THUS
THE UPSLOPE STORMS SHOULD ONLY MAKE IT AS FAR EAST AS WESTERN KS
DURING THE NIGHTTIME HOURS NEXT WEEK.
