AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DODGE CITY KS
346 PM CDT TUE AUG 3 2010

.DISCUSSION...

DAYS 1-2...

A WEAK JET STREAM WAS MOVING OUT OF COLORADO INTO WESTERN KANSAS
THIS AFTERNOON. AN OUTFLOW BOUNDARY FROM LAST NIGHT'S CONVECTION WAS
SITUATED OVER SOUTHERN KANSAS LATE THIS AFTERNOON. TOWERING CUMULUS WERE
DEVELOPING ALONG THIS BOUNDARY AS OF 3 PM OVER FAR SOUTHWEST KS. THIS
BOUNDARY SHOULD FINALLY LOSE DEFINITION THIS EVENING AND REDEVELOP FURTHER
NORTH. HIGH BASED THUNDERSTORMS WERE TRYING TO INITIATE OVER SOUTHEAST
COLORADO THIS AFTERNOON. THE MODELS MOVE A CLUSTER OF STORMS ACROSS
WESTERN AND NORTHERN KANSAS TONIGHT WITH THE NAM BEING FURTHER SOUTH
INTO OUR FCST AREA. SINCE THE GFS DIDN'T RESOLVE THE OUTFLOW
BOUNDARY, OPTED TO NOT GO WITH THIS MODEL FOR STORM CLUSTER
LOCATION. THE NAM INITIALIZED BETTER, ALBEIT NOT PERFECT, SO THIS
FCST IS BASED MORE OFF THE NAM SOLUTION.

AS UPPER TROUGHING PROGRESSES INTO THE UPPER MIDWEST ON WEDNESDAY,
THE SFC FRONT SHOULD PROGRESS BACK INTO SOUTHWEST KS ALONG WITH ADDITIONAL
CHANCES FOR STORMS. THE BEST CHANCE OF AFTERNOON STORMS MAY BE
ALONG THE BOUNDARY FROM DDC SOUTHWARD. OUR FCST AREA WILL BE IN
THE RIGHT EXIT REGION OF ANOTHER WEAK JET STREAK BY WEDNESDAY NIGHT
AND STORM CHANCES LOOK A LITTLE BETTER FOR THIS PERIOD, ESPECIALLY
CLOSE TO THE FRONTAL BOUNDARY IN OUR SOUTHERN COUNTIES.
TEMPERATURES WILL BE COOLER BEHIND THE FRONT ON WEDNESDAY IN OUR
NORTHERN COUNTIES BUT STILL VERY HOT ALONG THE OKLAHOMA STATE
LINE. THE EFFECTIVE SFC BOUNDARY SHOULD BE JUST TO OUR SOUTH ON
THURSDAY WITH MOISTURE POOLING NORTH OF THE BOUNDARY. THIS COULD
SET THE STAGE FOR MCS ACTIVITY THURSDAY NIGHT. ANY STORMS THAT
DEVELOP ON THE HIGH PLAINS TO OUR WEST COULD VERY WELL PROGRESS
INTO WESTERN KS GIVEN THE INCREASING ZONAL MID LEVEL FLOW.

DAYS 3-7...

THE BEST CHANCE AT ANY DECENT PRECIPITATION WILL COME EARLY IN THE
MEDIUM RANGE...THURSDAY NIGHT INTO EARLY FRIDAY...AS WARM ADVECTION
WILL INCREASE WITH THE FRONT LIFTING BACK TO THE NORTH IN RESPONSE
TO INCREASING SOUTHWESTERLY MOMENTUM ACROSS THE CENTRAL/NORTHERN
ROCKIES.  H8-7 WARM ADVECTION AND FRONTOGENESIS IS SUGGESTED BY THE
DETERMINISTIC GFS AND ECMWF MODELS TO BE BEST DURING THE OVERNIGHT
HOURS THURSDAY NIGHT INTO EARLY FRIDAY WITH BOTH MODELS SHOWING A
FAIR AMOUNT OF CONVECTIVE QPF AS A RESULT WITH CHANCE POPS (30
PERCENT) ACROSS MUCH OF THE CWA IN THE FORECAST.  BEGINNING
FRIDAY...PRECIPITATION CHANCES WILL DIMINISH GREATLY AS LOW LEVEL
FRONTOGENESIS BECOMES REFOCUSED ACROSS THE NORTHERN PLAINS IN
RESPONSE TO THE NEXT PACIFIC JET CORE COMING OUT OF THE ROCKIES.  H5
ANTICYCLONE CENTER WILL BECOME BETTER DEFINED BY THE WEEKEND OVER
OKLAHOMA.  INCREASING LOW LEVEL THICKNESS/THERMAL FIELDS WILL ONCE
AGAIN SUPPORT DAILY HIGH TEMPERATURES IN EXCESS OF 100 DEGREES
ACROSS MUCH OF THE DDC FA STARTING SATURDAY.  THIS WAS ALREADY IN
THE FORECAST FOR THE MOST PART ACROSS MUCH OF THE DDC FA...AND HAVE
EXTENDED THIS INTO THE NEW "DAY 7" NEXT TUESDAY.  THE MEDIUM RANGE
KINEMATIC AND MASS FIELDS OFF THE GFS AND ECMWF DO NOT INSPIRE MUCH
HOPE AT ALL (AT LEAST THROUGH ABOUT 12 AUGUST) AS FAR AS A COOL DOWN
WITH A FRONT TO RELIEVE THE REGION OF THIS PERSISTENT HEAT.

&&

.AVIATION...

THERE IS A SMALL PROBABILITY OF ISOLATED THUNDERSTORMS AFFECTING
KDDC, KGCK, KHYS THIS EVENING AND WILL KEEP THE FORECAST OF CB IN
THE TAF.  THE BEST CHANCE FOR ORGANIZED THUNDERSTORM ACTIVITY WILL
BE ACROSS NORTHWEST KANSAS...PERHAPS AFFECTING KHYS LATE IN THE
EVENING.  OTHERWISE, VFR CONDITIONS WILL CONTINUE TO PREVAIL THROUGH
18Z WEDNESDAY.
