Hail and Damaging Winds in Kansas, July 29, 2003

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DODGE CITY KS
211 PM CDT TUE JUL 29 2003

DAYS 1-2...

AM STILL CONSIDERING ADDING POPS ACROSS OUR NORTHERN ZONES FOR
TONIGHT BASED ON SATELLITE AND RADAR INDICATIONS OF STORM
DEVELOPMENT ALONG A SURFACE TROUGH/COLD FRONT TO OUR NORTH. IF THESE
STORMS HOLD TOGETHER IN THE NW FLOW, THEY COULD ENTER OUR NORTHERN
AND WESTERN ZONES BY THIS EVENING.

MAIN CONCERNS FOR THE SHORT TERM WILL AGAIN BE PRECIP CHANCES AND
TEMPERATURES. POTENT WAVE OVER MANITOBA CURRENTLY WILL DROP
SOUTHEAST INTO THE WESTERN GREAT LAKES BY THURSDAY MORNING AND WILL
FORCE ANOTHER WEAK COLD FRONT SOUTH THROUGH THE PLAINS ON WEDNESDAY.
THE BOUNDARY WILL PROBABLY REACH MY NORTHERN ZONES BY AROUND MIDDAY
OR SO. CONVERGENCE ALONG THE FRONT DOESNT LOOK THAT IMPRESSIVE TO
ME SO I WILL BASE MY PRECIP FORECAST ON THE THERMODYNAMICS. WITH
700MB TEMPS BELOW 10C ON WEDNESDAY AND FORECAST SURFACE TEMPS IN
THE LOW TO MID 90S, CONVECTIVE TEMPS MAY BE REACHED ANYWHERE ACROSS
THE CWA DURING THE AFTERNOON. WILL LEAVE CURRENT FORECAST OF 20
POPS OVER THE ENTIRE AREA FOR MUCH OF THE DAY AS A RESULT. FOR
THURSDAY, THE UPPER RIDGE NUDGES SLIGHTLY EASTWARD, ALLOWING FOR
WARM MID LEVEL AIR TO MOVE INTO THE HIGH PLAINS. MODEL SOUNDINGS
INDICATE MIXING TO AROUND 700MB WHERE TEMPS ARE EXPECTED TO CLIMB
INTO THE LOWER TEENS CELSIUS. TAKE INTO ACCOUNT A SUPER NEAR THE
SURFACE AND TEMPS MAY BE CLOSE TO 100 FROM DDC EASTWARD. AS
FOR PRECIP CHANCES, SOUNDINGS ALSO INDICATE THAT CONVECTIVE TEMPS MAY
BE REACHED ACROSS THE EASTERN CWA DURING THE AFTERNOON, SO I EXPANDED
THE CURRENT 20 POP TO INCLUDE THE EASTERN HALF OF THE AREA. THE ETA
INDICATES THAT A DRYLINE MAY SET UP OVER THE EASTERN ZONES DURING
THE AFTERNOON AS WELL, WHICH COULD AID IN TSTORM DEVELOPMENT THERE.

DAYS 3-7...

LATEST MODEL RUNS SHOW PRETTY GOOD WAVE ENTERING WESTERN KANSAS ON
FRIDAY AFTERNOON AS BETTER NORTHWEST FLOW DEVELOPS OVER REGION.
ADDED 30 POPS FOR LATE FRIDAY AFTERNOON AND EVENING. THEN THE UPPER
RIDGE RE-ESTABLISHES OVER EASTERN ROCKIES AND WE SHOULD SEE A RETURN
TO U90S/A100 BY THE END OF THE WEEKEND.
