.PREV DISCUSSION... /ISSUED 316 PM CDT FRI JUL 3 2009/

DISCUSSION...

ELEVATED SHOWERS AND ISOLATED THUNDERSTORMS OVER BROWN COUNTY SHOULD
MOVE EAST OF THE CWA BY 20Z. THIS AFTERNOON...A SURFACE TROUGH WAS
DEEPENING ACROSS WEST CENTRAL KS...SOUTHWEST ACROSS SOUTHEAST
CO...THEN SOUTHWARD ACROSS EASTERN NM. A SFC WARM FRONT EXTENDED
FROM THE SFC TROUGH...NORTHEAST OF HLC SOUTHEAST ACROSS THE
SOUTHWEST COUNTIES OF THE CWA INTO SOUTHEAST KS. AN EML HAS OVER
SPREAD THE CWA...THUS SFC BASED STORMS SHOULD NOT DEVELOP THROUGH
THE REMAINDER OF THE AFTERNOON HOURS ACROSS THE CWA. ACROSS
SOUTHWEST AND WEST CENTRAL KS...SFC TEMPS HAVE WARMED INTO THE MID
90S...WITHIN A DEGREE OR TWO OF CONVECTIVE TEMPS. THERE SHOULD BE
ENOUGH SFC CONVERGENCE FOR THUNDERSTORMS TO DEVELOP ACROSS SOUTHWEST
AND WEST CENTRAL KS THROUGH THE LATE AFTERNOON AND EARLY EVENING
HOURS. THESE STORMS WILL INITIALLY BE HIGH BASED WITH TEMPERATURE
AND DEW POINT TEMPERATURE DEPRESSIONS OF 30 TO 40 DEGREES. SOME OF
THESE STORMS WILL MOVE EAST INTO THE WESTERN COUNTIES OF THE CWA
LATER THIS EVENING. AS THE STORMS ACROSS WEST CENTRAL KS MOVE EAST
AND ENCOUNTER DEEPER MOISTURE THEY MAY INTENSIFY GIVEN SFC BASED
CAPES OF 2,000 TO 2500 J/KG ACROSS CENTRAL AND NORTH CENTRAL KS. THE
SPC MODIFIED RUC MODEL SHOWED GOOD VERTICAL WINDSHEAR ACROSS NORTH
CENTRAL KS WITH 0-3KM SRH OF 300 TO 400 J/KG AND 0-1KM SRH OF AROUND
200 J/KG. ANY STORM MOVING INTO NORTH CENTRAL KS LATER THIS EVENING
MAY INTENSIFY INTO A SUPERCELL THUNDERSTORM. HOWEVER...IF THE STORMS
DEVELOP INTO A LINE OR COMPLEX ACROSS WEST CENTRAL KS EARLY THIS
EVENING...THEN WIND AND LARGE HAIL WILL BE THE PRIMARY HAZARD.
EVENTUALLY A LINE OR COMPLEX OF THUNDERSTORMS WILL DEVELOP AND MOVE
EAST AND SOUTHEAST ACROSS THE REMAINDER OF THE CWA AFTER MIDNIGHT.
THE STORMS WILL PROBABLY WEAKEN AFTER MIDNIGHT AS THEY MOVE THROUGH
EAST CENTRAL KANSAS.

A 5H TROUGH WILL DIG SOUTHEAST ACROSS THE CENTRAL PLAINS TONIGHT
CAUSING A SFC COLD FRONT TO PUSH SOUTHEAST ACROSS THE CWA DURING THE
MORNING HOURS OF SATURDAY. THE SHOWERS AND THUNDERSTORMS AHEAD OF
THE COLD FRONT WILL SHIFT SOUTHEAST OF THE CWA DURING THE LATE
MORNING AND EARLY AFTERNOON HOURS. A FEW ISOLATED SHOWERS MAY
DEVELOP NORTH OF THE FRONT ACROSS THE EASTERN CWA DURING THE
AFTERNOON BUT SHOULD DISSIPATE BY EVENING AS LOW-LEVEL CAA DEEPENS
THE COOLER AND DRIER AIRMASS ACROSS THE CWA. HIGHS WILL RANGE FROM
THE UPPER 70S TO AROUND 80 ACROSS THE NORTHERN COUNTIES WITH LOWER
TO MID 80S ACROSS THE REMAINDER OF THE CWA. NORTH WINDS WILL
INCREASE TO 15 TO 20 MPH WITH GUSTS OF 25 MPH DURING THE AFTERNOON
HOURS BUT SHOULD DIMINISH DURING THE AFTERNOON HOURS.

GARGAN

SATURDAY NIGHT AND SUNDAY HIGH PRESSURE WILL BUILD INTO THE CENTRAL
PLAINS WITH NORTHWEST FLOW IN THE MID LEVELS CONTINUING AS A RIDGE
REMAINS OVER THE ROCKIES. SOME DRIER AIR WILL WORK IS WAY INTO THE
REGION AND GRADUALLY CLEAR SKIES. INDEPENDENCE EVENING LOOKING DRY
ACROSS THE CWA WITH SUBSIDENCE THROUGH THE EVENING AND OVERNIGHT.
LOWS SUNDAY MORNING WILL BE IN THE LOW TO MID 60S.

SUNDAY NIGHT AND MONDAY THE NAM AND THE GFS HINT OF A WAVE MOVING
SOUTHEAST OUT OF MONTANA SUNDAY NIGHT. MOISTURE TRANSPORT WILL BE
ORIENTATED INTO THE HIGH PLAINS IN SOUTHEASTERLY UPSLOPE. FURTHER
EAST LOW TO MID LEVEL FLOW IS WEAK AND MOISTURE IS LOWER. CORFIDI
VECTORS SUGGEST A SOUTH SOUTHEAST STORM MOVEMENT SUNDAY NIGHT INTO
THE MOISTURE...THEN BECOME MORE SOUTHEAST TOWARD 12Z MONDAY. IF
STORMS ARE ABLE TO HOLD TOGETHER COULD SEE SOME SHOWERS LATE SUNDAY
NIGHT OR MONDAY MORNING IN NORTH CENTRAL KANSAS. WILL LEAVE OUT FOR
NOW AND SEE IF FUTURE MODEL RUNS PICK UP ON THE WAVE. THE GFS LOOKS
TO SUFFER FROM SOME CONVECTIVE FEEDBACK ACROSS NEBRASKA WHILE THE
NAM IS MUCH WEAKER. THE 12Z ECMWF KEEPS THE CWA DRY DURING THIS
PERIOD.

FOR TUESDAY THROUGH FRIDAY MODELS CONTINUE IN AGREEMENT WITH THE
BUILDING OF THE RIDGE INTO THE CENTRAL PLAINS. TEMPERATURES WILL
CONTINUE TO WARM EACH DAY WITH AREAS IN CENTRAL KANSAS AROUND THE
CENTURY MARK BY THURSDAY AND FRIDAY. ALSO LATER IN THE WEEK THE
SURFACE DEW POINTS INCREASE INTO THE UPPER 60S TO LOW 70S WHICH
COMBINED WITH THE HIGHS IN THE 90S TO NEAR 100 WILL YIELD HEAT
INDICES AROUND 105 BY WEEKS END. WAVES MOVING AROUND THE UPPER HIGH
WILL STAY WELL TO THE WEST AND NORTH OF THE CWA DURING THIS PERIOD.
LOOKS LIKE THE HOT SUMMER WEATHER IS COMING BACK.
