AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DODGE CITY KS
335 PM CDT WED AUG 13 2008

.DISCUSSION...

DAYS 1-2...

THE MAIN FORECAST DECISION COMES TONIGHT ON WHEN AND WHERE SEVERE
STORMS MIGHT FORM.  THE SECOND PHASE OF DECISION MAKING IS THURSDAY
EVENING/NIGHT WHEN ANOTHER ROUND OF SEVERE WEATHER IS POSSIBLE.

FOR MUCH OF THIS FORECAST PACKAGE, LITTLE CHANGE WAS MADE.  THE 30
TO 40 PERCENT POPS SEEM APPROPRIATE FOR TONIGHT.  THINK WITH A LOT
OF CLEARING EARLY TODAY AND A LONG PERIOD OF SURFACE HEATING, THE
LOWER LAYERS OF THE ATMOSPHERE HAVE DE-STABILIZED MORE AND MORE AS
THE AFTERNOON PROGRESSED.  WILL MENTION LARGE HAIL AND DAMAGING
WINDS IN MY WESTERN THIRD CWA THIS EVENING, AND SPREAD THAT SEVERE
POSSIBLE WORDING EAST TO NEARLY ALL THE CWA OVERNIGHT.

AN UPPER LOW IS BOTH DISCERNIBLE ON WATER VAPOR IMAGERY AND
FORECAST BY NEARLY EVERY MODEL TO MOVE AND DEEPEN AND BE OVER
WESTERN NEBRASKA BY THURSDAY NIGHT.  THIS UPPER LOW WILL SLOWLY DIG
AND MOVE ACROSS KANSAS AS A CUT OFF LOW THROUGH FRIDAY AND BEYOND.
SINCE THE STEERING UPPER LEVEL FLOW IS WELL TO THE NORTH, THIS SLOW
MOVING SYSTEM SHOULD BRING SOME DECENT PRECIP (QPF) TO WESTERN
KANSAS. ADDITIONALLY, A COLD FRONT WILL WORK SOUTH FROM THE NORTHERN
PLAINS, AND THE BEST TIMING FOR CROSSING OUR CWA WILL BE THURSDAY
AFTERNOON INTO THURSDAY EVENING.  THIS FRONT WILL ADD GOOD LIFT TO
THE MOISTURE IN PLACE, AND BE UNDER THE SYNOPTIC SCALE LIFT FROM THE
UPPER LOW TO OUR WEST.  WILL GO WITH LIKELY POPS FOR TRW/TRW-
THURSDAY NIGHT AND KEEP 40-50 CHANCE POPS GOING ON FRIDAY. JUST WHERE
THE HEAVIER RAINFALL WILL END UP IS HARD TO PINPOINT, BUT FOR NOW
THINK THE NORTH AND EASTERN ZONES WILL END UP WITH MORE RAINFALL DUE
TO HIGHER DEWPOINTS AND AVAILABLE LOW LEVEL MOISTURE. THE MODELS ARE
KEYING ON THE LOW LEVEL WARM TEMP AND MORE MOIST RH FIELDS.  THIS
POINTS TOWARD THE SOUTHEAST COUNTIES RECEIVING THE MOST RAIN. WILL
BUMP UP QPF IN THE SOUTHEAST FOR THURSDAY NIGHT AND FRIDAY.

TEMPERATURES STAYED PRETTY MUCH AS BEFORE.  WARM THURSDAY IN THE
MID TO UPPER 80S, THEN A SIGNIFICANT COOL OFF FRIDAY WITH CLOUDY,
RAINY CONDITIONS.  FRIDAY HIGHS SHOULD VARY FROM 75 AT GCK AND HYS
TO 81 AT P28.

DAYS 3-7...

THE MODELS ARE COMING INTO AGREEMENT WITH THE LARGE SCALE FEATURES
TODAY. ALL MODELS DROP AN UPPER LOW SOUTHWARD INTO COLORADO AND THEN
SLOWLY MOVE THE FEATURE INTO KS/OK BY EARLY NEXT WEEK. THE UKMET AND
ECMWF ARE IN EXCELLENT AGREEMENT THROUGH 144 HRS AND WERE GENERALLY
FOLLOWED. AMPLE LOW LEVEL MOISTURE SHOULD BE AVAILABLE FOR THIS
SYSTEM. PERIODS OF WIDESPREAD LIFT ALONG WITH THE ABUNDANT MOISTURE
MAY BRING LOCALLY HEAVY RAIN. POPS WERE RAISED FOR SEVERAL PERIODS
INTO SUNDAY NIGHT. SHOWERS/STORMS MAY PERSIST EVEN INTO TUESDAY IN
OUR EASTERN COUNTIES.

HIGHS AND LOWS WILL BE DRAMATICALLY IMPACTED BY THE TIMING OF THICK
CLOUDS AND PRECIP. BUT A CONSERVATIVE FORECAST IS FOR HIGHS IN THE
70S TO MID 80S EACH DAY FROM FRIDAY INTO TUESDAY. MAXES COULD BE
LOWER GIVEN EXPECTED PERSISTENT UPSLOPE FLOW AND POSSIBLE LOW
CLOUDINESS. GIVEN EXPECTED DEWPOINTS IN THE UPPER 50S TO MID 60S,
LOWS ARE EASIER TO PREDICT THAN THE HIGHS.  AFTER THE SURFACE FRONT
PASSES, SEVERE WEATHER SHOULD NOT BE A BIG CONCERN. BUT LOCALIZED
FLOODING IS A POSSIBILITY.

&&

.AVIATION...

VFR CONDITIONS CAN BE EXPECTED THIS EVENING. THUNDERSTORMS MAY
DEVELOP LATE THIS EVENING AND TONIGHT. OF COURSE VSBYS AND CIGS
WOULD BE MUCH LOWER UNDER THE STORMS.
