AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DODGE CITY KS
352 PM CDT TUE SEP 14 2010

.DISCUSSION...

DAYS 1-2...

A STRONG SHORTWAVE TROUGH WILL PASS ACROSS THE CENTRAL PLAINS LATE
TONIGHT AND WEDNESDAY. THE SFC REFLECTION OF THIS WAVE WILL
DEVELOP ALONG THE FRONT RANGE LATER THIS AFTERNOON AND THEN MOVE
EASTWARD ACROSS NEBRASKA AND INTO IOWA AND SOUTHERN MN BY
WEDNESDAY EVENING. FURTHER SOUTH, THERMAL CONTRIBUTIONS DUE TO
DOWNSLOPE FLOW WILL LEAD TO THE DEVELOPMENT OF A TRAILING SFC LOW
ALONG THE COLD FRONT ACROSS KS. BUT THE TRUE SYNOPTIC LOW WITH LOW
LEVEL WIND CIRCULATION WILL BE FURTHER NORTHEAST. THE BEST DEEP
LAYER MOISTURE AND CONVERGENCE WILL BE WELL TO OUR NORTHEAST AHEAD
OF THE SFC LOW. THERE IS A SLIGHT CHANCE OF THUNDERSTORMS IN OUR
NORTHERN COUNTIES TONIGHT ON THE SOUTHERN END OF THE UPPER DYNAMIC
LIFT, AND THEN ALONG THE TRAILING COLD FRONT IN OUR FAR SOUTHEAST
WEDNESDAY AFTERNOON. GIVEN THE DOWNSLOPE FLOW, TEMPS OUGHT TO SOAR TO
NEAR 100 IN AREAS SOUTHEAST OF DDC, ESPECIALLY ON THE LOWER TERRAIN
IN SOUTHERN CLARK COUNTY WHERE IT COULD REACH 102F.

AFTER THE UPPER JET STREAK PASSES, OUR FCST AREA WILL BE IN THE
ENTRANCE REGION OF THE JET BY THURSDAY. THE MODELS SHOW FAIRLY HIGH
RH AT MID LEVELS (600-500MB) AND THE NAM/ECMWF ACTUALLY HAVE SMALL
AMOUNTS OF QPF. DECIDED TO INTRODUCE SMALL POPS FOR SHOWERS BUT
THIS PRECIP MAY NOT EVEN REACH THE GROUND GIVEN THE DRY LOW LEVELS.
TEMPS SHOULD BE COOLER BEHIND THE FRONT ON THURSDAY, ESPECIALLY IN
AREAS THAT HAVE EXTENSIVE MID LEVEL CLOUD.

DAYS 3-7...

THE MEDIUM RANGE MODELS ALL CONTINUE TO BE IN VERY GOOD AGREEMENT
WITH THE DEVELOPMENT OF A BROAD UPPER LEVEL RIDGE DEVELOPING OVER
MUCH OF THE CONUS THROUGH THE LATTER PART OF THIS WEEK INTO THE
WEEKEND. A DEEP UPPER LEVEL LOW PRESSURE CENTER OVER THE OVER FAR
NORTHERN CANADA WILL ROTATE SOUTH THROUGH THE SOUTHERN PROVINCES AND
INTO THE HUDSONS BAY REGION BY SATURDAY. AN ASSOCIATED COLD FRONT IS
FORECAST TO PUSH SOUTH INTO THE CENTRAL PLAINS ON SATURDAY AND MAY
BE AS FAR SOUTH AS MY NORTHERN CWA. MODEL SOUNDINGS DON'T SHOW VERY
SIGNIFICANT INSTABILITY ALONG THE FRONT WHICH MAKES SENSE GIVEN THE
WARMER MID LEVELS. THE MODELS BREAK OUT SOME QPF ALONG AND MAINLY
NORTH OF THE CWA ON SATURDAY BUT AM OPTING TO LEAVE THE FORECAST DRY
FOR NOW. THE FRONT LIFTS OFF TO THE NORTH ON SUNDAY AS ANOTHER
STRONG WAVE MOVES ONSHORE IN THE PACIFIC NORTHWEST. WE SHOULD SEE A
FEW DAYS OF TEMPERATURES CLIMBING BACK UP TO AROUND OR OVER 90
DEGREES BEFORE ANOTHER COLD FRONT...ASSOCIATED WITH THE NEXT
SHORTWAVE...PUSHES SOUTH THROUGH THE CENTRAL HIGH PLAINS. THE GFS
AND TO A LESSER EXTENT THE ECMWF SHOW A STRONGER WAVE MOVING ACROSS
THE CONUS LATER NEXT WEEK WHICH COULD BRING SIGNIFICANTLY COOLER
TEMPERATURES TO THE REGION ALONG WITH A BETTER CHANCE FOR
PRECIPITATION.  WILL ADJUST THE WEEK TWO FORECAST TO NEAR NORMAL FOR
TEMPERATURES AND PRECIPITATION.

.AVIATION...

WIDELY SCATTERED THUNDERSTORMS DEVELOPING OVER THE TEXAS PANHANDLE
SHOULD CONTINUE TO DEVELOP AND COULD MOVE NORTH OF THE KANSAS BORDER
DURING THE LATE AFTERNOON HOURS. THINK THAT THESE STORMS WILL MAINLY
STAY SOUTHEAST OF DODGE CITY SO WILL JUST HAVE A MENTION OF CB'S IN
THE TAF. OTHER STORMS ARE EXPECTED TO DEVELOP OVER EASTERN COLORADO
THROUGH THE LATE AFTERNOON HOURS AND MOVE OUT INTO NORTHWEST KANSAS
AND NEBRASKA THIS EVENING.  STORMS FROM THIS AREA COULD IMPACT THE
HAYS AREA AFTER SUNSET BUT SHOULD BE MOVING OUT OF THE AREA BY 06Z.
THERE COULD ALSO BE SOME AREAS OF STRATUS DEVELOPING AROUND HAYS
LATER THIS EVENING NORTH OF A RETREATING FRONTAL BOUNDARY. THE
STRATUS SHOULD BE DIMINISHING LATER TONIGHT AS THE BOUNDARY MOVES
NORTH OUT OF THE AREA.
