AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DODGE CITY KS
202 PM CDT SUN JUN 20 2004

.DISCUSSION...

DAYS 1-2...
ONCE AGAIN CONVECTION DEVELOPING OVER THE HIGHER TERRAIN, MAINLY IN
BOU AREA AS MCS FROM THIS MORNING MOVES SOUTH INTO OK. SFC BOUNDARY
APPEARS TO HAS STALLED OUT IN THE TX PANHANDLE BY LATE MORNING WITH
DHT OBS SUGGESTING IT WAS ALREADY BEGINNING TO MOVE BACK NORTHWARD.
BASED ON 7H TEMPS OF 9-10C...CAP SHOULD SEE CU BECOME MORE DEVELOPED
THAN WHAT IS OUTSIDE AT 18Z WITH MID-UPPER 80S. MOST FAVORABLE AREA
FOR THIS WILL BE IN THE CNTL/SW CWA SO WITH THIS IN MIND WILL KEEP
SMALL POPS GOING LATE THIS AFTERNOON INTO EVENING HERE WHICH IS ALSO
NEAR THE RETURNING SFC BOUNDARY AND LARGEST CAPE VALUES.

THE MORE INTERESTING WEATHER WILL BE LATER TONIGHT AS THE DEVELOPING
STORMS IN COLORADO MOVE EASTWARD INTO WESTERN KS.  MID LVL
BAROCLINIC ZONE STILL IN PLACE FROM NE CO INTO CNTL KS AND WITH A
BETTER LLJ PROGGED TO DEVELOP, WAA AND TONGUE OF MOISTURE EXTENDING
FROM NE CO INTO SC KS AHEAD OF THESE STORMS SHOULD SEE ANOTHER MCS
MOVE ACROSS THE CWA LATER TONIGHT. PCPN H20 VALUES VERY SIMILAR TO
LAST NIGHTS WHERE 1-2 INCHES FELL BASED ON COOP REPORTS. WITH BETTER
LIFT PRESENT CURRENTLY THINK UP TO 3 INCHES IS NOT OUT OF THE
QUESTION SO WITH FFG IN SOME AREAS SHOWING ONLY 6HR VALUES OF LESS
THAN THREE ESPECIALLY IN THE NORTH AND REVIEWING WHERE THE HEAVIEST
RAINS HAD FALLEN OVER THE LAST 72 HOURS VIA HYDROVIEW MPE WILL GO
AHEAD AND ISSUE A FLOOD WATCH FOR A OUR NORTHERN COUNTIES NEAR THE
GLD AREA AND OUR ERN CWA BOARDING ICT.

FOLLOWING THIS A COLD FRONT WILL PUSH SOUTH INTO NORTHERN OKLAHOMA
ON MONDAY BRINGING WITH IT A REINFORCEMENT OF COOLER AIR. PCPN
CHANCES MONDAY NIGHT WILL BE NEAR THIS FRONT WHICH WILL EXTEND FROM
NORTHERN OKLAHOMA INTO SE COLORADO. WILL THEREFORE GRADIENT POPS
FROM THE HIGHER GRIDS OF OUN,AMA,PUB DOWNWARD IN OUR SW/SRN CWA.
AFTER THIS SFC HIGH BUILDS IN MONDAY NIGHT AND TUESDAY. SO FOR MOST
OF THE CWA WILL LEAVE FORECAST DRY.
DAYS 3-7...
MEDIUM RANGE MODELS HAVE NORTHWEST FLOW ALOFT DOMINATING THE PLAINS
AS A STRONG UPPER LOW HOVERS NORTH OF THE GREAT LAKES.  VARIOUS
SHORTWAVE TROUGHS WILL BE ROTATING AROUND THE UPPER LOW AND BRINGING
REINFORCING SHOTS OF COOLER AIR, WITH THE GFS AND ECMWF SHOWING A
FAIRLY VIGOROUS ONE COMING DOWN WEDNESDAY NIGHT INTO THURSDAY.  AT
THE SFC, A GENERAL EASTERLY COMPONENT WILL CONTINUE TO BRING MOIST
AIR UPSLOPE ACROSS SOUTHWEST KS.  MUCH WILL DEPEND ON WHERE FRONTAL
AND OUTFLOW BOUNDARIES END UP, BUT SEE NO REASON WHY THE TREND OF
CONVECTION FIRING IN THE HIGHER TERRAIN OF EASTERN CO AND MOVING
EASTWARD AS AN MCS WONT CONTINUE.  KEPT THE POPS THAT WE HAD GOING
FOR WED, THURS, AND FRI NIGHTS.  WITH PLENTY OF MOISTURE AND CLOUDS
HANGING AROUND THE AREA AND POSSIBLE FRONTAL BOUNDARIES COMING
THROUGH TEMPS SHOULD REMAIN BELOW CLIMO, SO TWEAKED HIGHS DOWN FOR
THURS AND FRI A BIT.  THE NEXT PROBLEM WILL BE HOW FAST THE UPPER
LOW MOVES EAST AND ALLOWS RIDGING TO BUILD IN.  THE OPERATIONAL GFS
KEEPS US IN NORTHWEST FLOW THROUGH MOST OF THE WEEKEND, NOT REALLY
BRINGING IN THE HIGHER HEIGHTS UNTIL NEXT TUES.  THE MAIN GFS
ENSEMBLES ARE PRETTY CONSISTENT WITH THE OPERATIONAL RUN, BUT THE
CANADIAN AND CDCS RE-FORECAST ENSEMBLES ARE A LITTLE FASTER AND
BUILD THE RIDGE INTO THE PLAINS OVER THE WEEKEND.  STILL, EVEN THE
CDC HAS COOLER THAN AVG 850MB TEMP ANOMALIES OVER THE AREA THROUGH
SATURDAY.  WILL KEEP THE OVERALL WARMING TREND, BUT WILL TWEAK TEMPS
DOWN A BIT ON SAT TO JUST BELOW CLIMO.  MINOR CHANGES ELSEWHERE IN
THE FORECAST.
