Hail and Damaging Winds in Kansas, August 6, 2007

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GOODLAND KS
200 PM MDT MON AUG 6 2007

.DISCUSSION...FORECAST CONCERNS ARE ON PRECIPITATION CHANCES OVER
THE NEXT FEW DAYS.

.SHORT TERM (TONIGHT-THURSDAY NIGHT)...

TONIGHT-TUESDAY...ANOTHER UPPER LEVEL DISTURBANCE EMBEDDED WITHIN
MID TO UPPER LEVEL MOISTURE WILL MOVE ACROSS THE AREA TONIGHT FROM
CENTRAL COLORADO. THIS WILL PROVIDE ANOTHER CHANCE AT SHOWERS AND
THUNDERSTORMS WITH THE BEST CHANCE INCREASING TOWARD THE
KANSAS/NEBRASKA BORDER. THIS FEATURE WILL BE EXITING THE AREA
TUESDAY MORNING. BY TUESDAY AFTERNOON ANOTHER SURGE OF MOISTURE
WILL MOVE INTO THE SOUTHWEST PART OF THE FORECAST AREA WHERE LOW
CHANCE POPS WILL BE INSERTED...DECREASING TO SLIGHT CHANCE POPS
ACROSS THE EAST AND NORTHEAST. AFTERNOON TEMPERATURES WILL BE
NOTICEABLY COOLER...PARTLY DUE TO THE INCREASED CLOUDINESS BUT ALSO
COOLER 850 TEMPERATURES. WILL STAY CLOSE TO CURRENT FORECAST HIGHS
OF AROUND 90 EXCEPT MID 90S ACROSS THE EAST AND SOUTH.

TUESDAY NIGHT-WEDNESDAY NIGHT...TUESDAYS FEATURE WILL MOVE ACROSS
THE AREA WITH NGM/NAM FAVORING THE SOUTHEAST HALF WHILE THE GFS
FAVORS THE NORTHWEST HALF. KEPT THE PREVIOUS FORECAST OUTLINE OF
HIGHEST POPS ACROSS THE NORTHWEST WHICH FOR THE PAST SEVERAL DAYS
HAS WORKED OUT BETTER. GIVEN LITTLE CHANGE IN THE UPPER FLOW THIS
SEEMS REASONABLE. ON WEDNESDAY THE AREA IS IN A LULL WITH REGARD
TO AVAILABLE MOISTURE AND LIFT. WILL KEEP A SLIGHT CHANCE OF
STORMS GOING FOR THE AFTERNOON ALTHOUGH RIGHT NOW ITS NOT REAL
PROMISING. HAVE REMOVED THE SLIGHT CHANCE POPS FOR WEDNESDAY NIGHT
AS WELL GIVEN THE REASONING FOR LACK OF STORMS EXPECTED WEDNESDAY.
AFTERNOON TEMPERATURES WILL WARM ANOTHER SEVERAL DEGREES FROM
MONDAYS READINGS PER MOS AND 850 TEMPS. WILL GO FOR MID 90S WEST
TO AROUND 100 OVER IN THE HILL CITY AREA.

THURSDAY-THURSDAY NIGHT...WILL KEEP IT DRY GIVEN A LACK OF DETAILS
AND RESOLUTION TO WEATHER FEATURES AND MOISTURE THAT MAY OR MAY
NOT PRODUCE CONVECTION. AFTERNOON TEMPERATURES WILL BE SIMILAR TO
THOSE ON WEDNESDAY AS 850 TEMPS FROM THE GFS/NAM SHOW LITTLE
CHANGE.

.LONG TERM (FRIDAY-MONDAY)...

UPPER LEVEL PATTERN FEATURES A BUILDING UPPER LEVEL HIGH PRESSURE
CENTER OVER THE CENTRAL AND SOUTHERN PLAINS WITH THE MAIN STORM
TRACK UP ALONG THE NORTHERN PLAINS/CANADIAN BORDER.

850 TEMPERATURES FROM THE GFS FAVOR HIGHS EACH DAY IN THE UPPER
90S/LOW 100S...NOT FAR OFF FROM THE MEX/ENSEMBLE MOS GUIDANCE.

AS FAR AS PRECIPITATION CHANCES...WILL KEEP THIS PORTION OF THE
FORECAST DRY. WITH 700MB TEMPERATURES PUSHING THE MID TO UPPER
TEENS CONVECTION WOULD BE HARD BUT NO IMPOSSIBLE TO COME BY.
700-500 MOISTURE IS AVAILABLE FROM TIME TO TIME AROUND THE
PERIPHERY OF THE UPPER RIDGE WITH BEST CHANCE OF ANY PRECIP ACROSS
FAR EASTERN COLORADO AND ADJACENT LOCATIONS IN WESTERN
KANSAS/SOUTHWEST NEBRASKA. HOWEVER...WHERE THE MID LEVEL MOISTURE
IS MORE PLENTIFUL RESIDES THE WARMER/HOTTER MID LEVEL
TEMPERATURES.

&&

.AVIATION...

THUNDERSTORMS ARE EXPECTED TO DEVELOP THIS AFTERNOON ALONG A
SURFACE BOUNDARY IN ASSOCIATION WITH A MOIST UNSTABLE AIRMASS. IN
ADDITION AN UPPER LEVEL DISTURBANCE WILL MOVE ACROSS THE REGION
TONIGHT RESULTING IN SCATTERED THUNDERSTORMS. VFR CONDITIONS WILL
EXIST EXCEPT IN THOSE AREAS WHERE THUNDERSTORMS OCCUR. MVFR
CONDITIONS CAN BE EXPECTED WITH MOST OF THE THUNDERSTORMS. HOWEVER
A FEW STORMS ESPECIALLY NEAR THE KMCK TERMINAL MAY RESULT IN IFR
CONDITIONS ALONG WITH WIND GUSTS TO 40 KT AT LEAST THROUGH 06Z.
