AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO
316 PM CDT FRI APR 27 2007

.UPDATED AVIATION DISCUSSION...

.DISCUSSION...

UPPER LOW IN NORTHEASTERN KANSAS HAS TRIGGERED THE DEVELOPMENT OF
SCATTERED SHOWERS AND WIDELY SCATTERED THUNDERSTORMS. ALTHOUGH THERE
IS NO SIGNIFICANT SHEAR PRESENT...SBCAPE AROUND 400 J/KG HAS LED TO
THE DEVELOPMENT OF ISOLATED THUNDERSTORMS PRODUCING...A COUPLE PRODUCING SMALL
HAIL. FREEZING LEVELS WITHIN THIS REGION ARE AROUND 7500 FEET.

THE UPPER LEVEL STORM SYSTEM WILL CONTINUE TO MOVE EAST SOUTHEAST
THIS EVENING AND POSE A THREAT FOR CONTINUED DEVELOPMENT OF SCATTERED
SHOWERS AND THUNDERSTORMS THIS EVENING...MAINLY ACROSS WEST CENTRAL
MISSOURI. A COUPLE OF THUNDERSTORMS MAY PRODUCE SMALL HAIL UNTIL SUNSET.

OTHERWISE...MUCH WARMER AND DRIER CONDITIONS ARE EXPECTED FOR THE
WEEKEND AS AN UPPER RIDGE BUILDS INTO THE REGION. DOWNSLOPE WARMING
ALONG WITH STRONG INSOLATION WILL PUSH TEMPERATURES WELL INTO THE 80S
ON SUNDAY.

DB

.EXTENDED FORECAST...

THE PRIMARY CONCERN IN THE MEDIUM RANGE PORTION OF THE FORECAST IS
WITH THE EVOLUTION OF AN UPPER SHORTWAVE TROUGH HEADING OUT OF
NORTHERN MEXICO...WITHIN THE CENTRAL CONUS MEAN RIDGE. THE
MEDIUM RANGE MODELS CONTINUE TO DIVERGE WITH THIS RATHER SMALL
FEATURE AS IT CROSSES THE SOUTHERN PLAINS EARLY NEXT WEEK. THE 06Z
GFS CLOSED OFF A CIRCULATION OF LOW PRESSURE OVER THE SOUTHERN
PLAINS AND BROUGHT IT INTO MISSOURI WEDNESDAY...WHEREAS THE 12Z GFS
ADVERTISED A CENTER OF HIGH PRESSURE IN THE SAME AREA. BECAUSE OF
THE CONTINUED UNCERTAINTIES WITH THE VARYING MEDIUM RANGE
SOLUTIONS...KEPT GOING LOW END PRECIPITATION CHANCES DURING THE
MIDDLE OF NEXT WEEK AT THIS TIME. THIS WILL BE FINE TUNED AS THE
MODELS ARE ABLE TO BETTER RESOLVE THIS FEATURE.

TEMPERATURES WILL CONTINUE WELL ABOVE NORMAL FOR MONDAY WITH A
THERMAL RIDGE BECOMING ORIENTED FROM NORTHERN KANSAS INTO NORTHERN
MISSOURI. TEMPERATURES WILL THEN COOL...RELATIVELY SPEAKING...BUT
SHOULD REMAIN IN THE ABOVE NORMAL RANGE FROM MID TO LATE NEXT WEEK.

.AVIATION...

WIDELY SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS WILL CONTINUE TO
AROUND 01Z...IN RESPONSE TO AN UPPER LEVEL STORM SYSTEM. A BROKEN
VFR CLOUD DECK WILL PERSIST THROUGH THIS EVENING...ALTHOUGH THERE IS
A SMALL CHANCE THAT THE CLOUD DECK MAY BRIEFLY FALL TO BETWEEN 2 AND
3 KFT THIS EVENING. OTHERWISE...CLEARING SKIES LATE THIS EVENING.
