AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DODGE CITY KS
337 PM CDT TUE JUL 14 2009

.DISCUSSION...

DAYS 1-2...

CONVERGENCE ALONG AND AHEAD OF COLD FRONT SHOULD HELP INITIATE A FEW
VERY HIGH BASED THUNDERSTORMS THIS EVENING. ELEVATED CONVECTION COULD
DEVELOP TONIGHT AS RICH 850MB MOISTURE POOLS NORTH OF THE FRONT IN WESTERN
AND CENTRAL KS. WESTERN KS SHOULD BE IN THE RIGHT REAR QUAD OF THE
UPPER JET AS WELL. HOWEVER, DRY AIR AT LOW LEVELS COULD DISCOURAGE
PRECIP. DEWPOINTS WERE IN THE 40S BEHIND THE FRONT EARLY THIS AFTERNOON.

SOME ELEVATED CONVECTION COULD PERSIST DURING THE DAY WEDNESDAY BUT
SFC BASED STORMS SHOULD BE TO OUR SOUTH. RICH MOISTURE WILL GET
BANKED AGAINST THE ROCKPILE IN UPSLOPE FLOW. AN MCS COULD DEVELOP
WED NIGHT AFTER INITIALLY DEVELOPING ON THE PALMER DIVIDE. THE
STEERING FLOW WILL BE VEERING TO THE WNW OVERNIGHT SO THE STORMS SHOULD
TURN TO THE SOUTHEAST INTO THE LOW LEVEL INFLOW. LOCALLY HEAVY RAINS
ARE POSSIBLE IN OUR SOUTHWEST. BU THE EXACT PLACEMENT OF THE STORM
CLUSTER PRECLUDES EVEN HIGHER POPS.

THE UPPER FLOW WILL TURN MORE NORTHWESTERLY BY THURSDAY, WITH A 700MB
BAROCLINIC ZONE ACROSS THE CENTRAL PLAINS AND PLENTY OF ELEVATED LOW
LEVEL MOISTURE ABOVE THE FRONTAL SURFACE. MCS DEVELOPMENT COULD
TAKE PLACE IN CENTRAL KS.

TEMPS SHOULD BE A LOT COOLER WEDNESDAY BEHIND THE FRONT. SOME RECOVERY
IN TEMPS MAY OCCUR THURSDAY BUT THE EXTENT OF THE REBOUND WILL DEPEND ON
COVERAGE OF CONVECTION DURING THE DAY.

DAYS 3-7...

THERE ARE NO SUBSTANTIAL CHANGES IN THE THINKING FROM YESTERDAY
REGARDING THE FORECAST FOR THE PERIOD THURSDAY NIGHT THROUGH NEXT
TUESDAY. A FAIRLY ACTIVE NORTHWEST UPPER FLOW PATTERN IS STILL
EXPECTED TO INFLUENCE WESTERN KANSAS WEATHER WITH A DAILY CHANCE OF
THUNDERSTORM ACTIVITY AS MOIST LOW LEVEL UPSLOPE WILL COMBINE WITH A
MID LEVEL BAROCLINIC ZONE.  THE TIMING OF THE DAILY CONVECTIVE
ACTIVITY IS IN QUESTION...BUT TYPICALLY IN THESE PATTERNS...SURFACE
BASED STORMS WILL FORM ACROSS THE HIGHER TERRAIN OF COLORADO AND
ROLL SOUTHEAST TOWARD SOUTHWEST KANSAS AFTER SUNSET...EVOLVING INTO
A FORWARD-PROPAGATING MCS DURING THE LATE NIGHT HOURS.  OTHER STORMS
MAY ALSO FORM DURING THE OVERNIGHT HOUR AS WELL...IN ADDITION
TO...OR IN PLACE OF THE COLORADO DEVELOPMENT.  ANTICIPATING WHICH OF
THE DAYS WILL BE THE MOST LIKELY FOR AGGRESSIVE THUNDERSTORM
ACTIVITY IS ALWAYS DIFFICULT...BUT THE GFS AND ECMWF BOTH SHOW A
DECENT UPPER LEVEL JET STREAK ROUNDING THE UPPER HIGH INTO THE HIGH
PLAINS FRIDAY.  THIS MAY BRING THE BEST THREAT FOR ORGANIZED
STRONG/SEVERE ACROSS SOUTHWEST KANSAS.  THE GOING POP/WX FORECAST
ACTUALLY LOOKED TO BE IN PRETTY GOOD SHAPE WITH RESPECT TO THIS
THINKING...SO NOT MUCH CHANGE WAS MADE IN THIS FORECAST.  OVERLY HOT
WEATHER IS NOT ANTICIPATED WITH DAILY HIGHS IN THE UPPER 80S TO
LOWER 90S MUCH OF THE LATE WEEK INTO THE WEEKEND.

&&

AVIATION...

ISOLATED TO SCATTERED CBS ARE EXPECTED AFTER 22Z ALONG A SLOW
MOVING FRONT MAINLY IN THE KGCK AND KDDC AREAS.  ONE OR TWO OF THESE
STORMS MAY IMPACT TERMINALS WITH STRONG WIND GUSTS GIVEN SUCH HOT
TEMPERATURES THIS AFTERNOON.  ADDITIONAL STORMS ARE POSSIBLE LATE
TONIGHT WHERE MOISTURE WILL POOL ALONG AND JUST NORTH OF THE SURFACE
FRONT.  A BAND OF LOW STRATUS IS ALSO POSSIBLE AROUND THE KGCK
TERMINAL LATE TONIGHT.
