.PREV DISCUSSION... /ISSUED 310 PM CDT SAT JUN 28 2008/

DISCUSSION...
MAIN FORECAST CONCERNS WILL DEAL WITH A UNSETTLED WEATHER PATTERN
POSSIBLY RETURNING TO KANSAS FOR NEXT WEEK.

TONIGHT
SYNOPTIC COLD FRONT CONTINUES TO SINK SOUTHWARD ACROSS KANSAS THIS
AFTERNOON AND LATEST VISIBLE SATELLITE IMAGERY SHOWS GOOD CLEARING
TAKING PLACE NEAR THE FRONTAL BOUNDARY. THIS WILL INCREASE THE
INSTABILITY OVER EASTERN KANSAS...AND COULD SEE A FEW STRONG
THUNDERSTORMS RE-DEVELOP ALONG THE FRONT LATER THIS AFTERNOON/EVENING
IN SOUTHEAST KANSAS. OTHERWISE...ANY LINGERING ACTIVITY SHOULD
QUICKLY SHIFT SOUTH OF THE BORDER BY SUNSET AS DRIER AIR QUICKLY
SPREADS SOUTHWARD INTO KANSAS BEHIND THE SURFACE COLD FRONT. THE
DRY AIR WILL PROVIDE RATHER PLEASANT OVERNIGHT LOWS FOR A CHANGE.

SUN-TUE
QUIET WEATHER CONDITIONS EXPECTED FOR SUNDAY AND MONDAY AS DRIER
LESS HUMID AIR WILL BE IN PLACE...THUS GIVING WAY TO A COUPLE 5-STAR
WEATHER DAYS. GFS/ECMWF MODELS SHOW SOME MOISTURE RETURNING LATE
MONDAY NIGHT INTO EARLY TUESDAY MORNING FROM WEST TEXAS INTO
SOUTHWEST KANSAS. ISENTROPIC LIFT OF THIS MOISTURE IN THE 310-315K
LAYER COULD SPARK OFF SOME ELEVATED ACTIVITY NEAR OR JUST WEST OF
HIGHWAY 14...HOWEVER WE WILL KEEP THINGS DRY FOR THAT PERIOD AND SEE
IF NEXT MODEL RUN SHOWS THE SAME SIGNAL. OTHERWISE...MOISTURE INFLUX
WILL INCREASE ON TUESDAY ACROSS KANSAS WITH UPSLOPE FLOW FAVORING
CONVECTIVE DEVELOPMENT LATE TUESDAY AFTERNOON/EVENING NORTH OF
CENTRAL KANSAS. THIS ACTIVITY COULD VENTURE SOUTHWARD INTO CENTRAL
KANSAS BY LATE TUESDAY NIGHT...AS LOW LEVEL JET BOOSTS THE MOISTURE
TRANSPORT AND MID-LEVEL WINDS STEER THE ACTIVITY SOUTHEASTWARD.

EXTENDED: WED-SAT
A UNSETTLED WEATHER PATTERN COULD BE SHAPING UP FOR KANSAS THIS
PERIOD AS NORTHWEST FLOW REGIME BECOMES ESTABLISHED IN THE MID-UPPER
LEVELS OF THE ATMOSPHERE.

CURRENT SATELLITE WATER VAPOR IMAGERY SHOWS A HEALTHY SYSTEM SOUTH
OF ALASKA...AND MEDIUM RANGE MODELS ARE IN GOOD AGREEMENT WITH THIS
SYSTEM MIGRATING EASTWARD ACROSS CANADA TOWARDS THE HUDSON BAY
REGION BY MID WEEK. GFS ENSEMBLE TRENDS SHOW THE UPPER TROUGH
DEEPENING ACROSS THE GREAT LAKES REGION WITH THE HUDSON BAY SYSTEM
FROM WEDNESDAY THROUGH LATE NEXT WEEK. THIS WILL PLACE KANSAS IN A
NORTHWEST FLOW REGIME ALOFT WITH SEVERAL IMPULSES ROUNDING THE UPPER
RIDGE AND DROPPING SOUTHEASTWARD ACROSS THE AREA...THUS KEEPING THE
WEATHER PATTERN UNSETTLED.
