259 PM CDT FRI JUN 27 2003

DAYS 1-2...
CHALLENGE CONTINUES TO BE POP/QPF FOR SATURDAY NIGHT BUT DID NOT
NEED TO ADJUST GOING GRIDS ALL THAT MUCH.  SAT LOOP SHOWS A S/W
TROF IN THE NORTHWEST FLOW OVER MONTANA AND ANOTHER FURTHER
NORTHWEST. THE MODELS DO NOT SEEM TO BE HANDLING THEM VERY WELL AND
AS A RESULT HAVE DISCREPANCIES AS TO WHERE THE FRONT WILL BE SATURDAY
AFTERNOON/EVENING.  THINK AT THIS TIME THAT FRONT WILL END UP
SOMEWHERE ACROSS CWA BY SATURDAY EVENING.  THE SECOND S/W SHOULD HELP
INITIATE AN MCS OVER NORTHEAST COLORADO/SOUTHEAST WYOMING THEN
PROPAGATE SOUTHEAST ALONG THE 500MB BAROCLINIC ZONE.  SHOULD BE A
FAIR AMOUNT OF MOISTURE OVER EASTERN COLORADO SO SOME MID/LATE
AFTERNOON STORMS ARE MOST CERTAINLY POSSIBLE NEAR THE FRONT. WILL
CONTINUE WITH INCREASING POPS TO 70 OR SO BUY SATURDAY EVENING WITH A
MENTION OF HEAVY RAIN.  THEN FOR SUNDAY AFTERNOON, MOISTURE SHOULD
STILL BE AROUND AND UNDER THE CONTINUED NW FLOW, EXPECT ADDITIONAL
STORMS TO DEVELOP OVER THE WEST LATE SUNDAY AFTERNOON AND MOVE EAST
INTO THE EVENING BUT DONT THINK IT WILL HAVE THE COVERAGE AS
SATURDAY NIGHT. THE ONLY OTHER THING TO MENTION IS THE POSSIBILITY OF
STRATUS TONIGHT/SATURDAY MORNING.  STRATUS REACHED THE WEST OK
PANHANDLE THIS MORNING.  SHOULD CONTINUE TO SEE AN INCREASE IN LOW
LEVEL MOISTURE OVERNIGHT WITH 30-35KT LLJ DEVELOPING.  LINGERING
STRATUS MAY KNOCK A FEW OFF HIGHS AND DID MAKE SOME MINOR ADJUSTMENTS
TO ACCOUNT FOR THIS.

DAYS 3-7...
NOT MANY CHANGES TO THE EXTENDED TODAY. RAISED POPS TO 40% SUNDAY
NIGHT BECAUSE WE COULD SEE ANOTHER ROUND OF MCS ACTIVITY MUCH LIKE
SAT NIGHT. COULD HAVE GONE HIGHER, BUT THIS BEST AGREES WITH OUR
NEIGHBORS AT THIS TIME. WILL KEEP POPS IN THE EAST ON MONDAY BECAUSE
I CANT RULE OUT SOME ISOLATED STORMS WITH A BREAKABLE CAP AND
65-70F DEWPOINTS OVER THE AREA. AFTER THAT, THE 500MB RIDGE NOSES
ITS WAY NORTHEAST INTO THE CENTRAL US AS HEIGHTS FALL ACROSS THE
PACIFIC NW. WITH THAT, MID LEVEL TEMPS ARE EXPECTED TO WARM INTO THE
MID TEENS WHICH SHOULD PROVIDE SOME CAPPING AND KEEP THINGS HOT AND
DRY FOR MUCH OF THE UPCOMING WEEK. IN THE WEEK 2 TIMEFRAME, THE
TROPICAL CONVECTION OVER THE INDIAN OCEAN AT THE MOMENT IS EXPECTED
TO SLOWLY SHIFT EASTWARD WHICH SHOULD ALLOW THE PATTERN TO PROGRESS
SOME WITH THE MEAN TROUGH OVER THE PAC NW SHIFTING EAST TO SOMEWHERE
AROUND THE NORTHERN ROCKIES. WITH THAT COULD SEE A FRONTAL BOUNDARY
COME DOWN AND STALL OUT, MOST LIKELY TO OUR NORTH AND BE A FOCUS FOR
CONTINUED STORM ACTIVITY. SO WILL GO ABOVE NORMAL ON RAINFALL AND
NEAR NORMAL TEMPS.

HAZARDOUS WEATHER OUTLOOK
NATIONAL WEATHER SERVICE DODGE CITY KS
500 AM CDT FRI JUN 27 2003

THIS HAZARDOUS WEATHER OUTLOOK IS FOR SOUTHWEST KANSAS.

.DAY ONE...TODAY AND TONIGHT

NO HAZARDOUS WEATHER IS EXPECTED AT THIS TIME.

.DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY

WIDESPREAD THUNDERSTORMS ARE EXPECTED TO DEVELOP OVER MUCH OF
SOUTHWEST KANSAS SATURDAY NIGHT. A SURFACE COLD FRONT WILL STALL
OUT OVER WESTERN KANSAS LATE SATURDAY. THIS WILL HELP FOCUS THE
DEVELOPMENT OF THUNDERSTORMS DURING THE LATE AFTERNOON HOURS. AT
THIS TIME, IT IS STILL UNCLEAR WHERE EXACTLY THE THUNDERSTORMS WILL
FIRST DEVELOP, HOWEVER ONCE THEY DO, THEY WILL LIKELY ORGANIZE INTO
A LARGE CLUSTER OF STORMS AND MOVE SOUTH THROUGH MOST OF SOUTHWEST
KANSAS DURING THE LATE EVENING AND OVERNIGHT HOURS. WITH LIGHT UPPER
LEVEL WINDS, THE PROBABILITY OF WIDESPREAD SEVERE WEATHER IS LOW, BUT
HEAVY RAINFALL FROM SLOW MOVING STORMS MAY PROMOTE A FLOODING RISK
OVER PORTIONS OF THE AREA. STAY TUNED TO UPDATED FORECASTS AND
OUTLOOKS CONCERNING THIS UPCOMING RAINFALL EVENT.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION WILL NOT BE REQUIRED TODAY AND TONIGHT.
