.DISCUSSION...
320 AM MDT SAT JUN 19 2010

UPPER FLOW WILL BE SOUTHWEST OVER KANSAS WITH A RIDGE MOVING INTO
THE PLAINS AND THEN SHIFTING EAST BY MONDAY. SURFACE LOW PRESSURE
WILL BE OVER SOUTHEAST COLORADO THROUGH THE PERIOD WITH THE FRONT
MOVING BACK AND FORTH ACROSS THE FA EACH AFTERNOON AND EVENING.

SHORTWAVES COME THROUGH THE FLOW EACH AFTERNOON AND EVENING THROUGH
MONDAY. THERE IS PLENTY OF CAPE (AROUND 4000 J/KG) AND GOOD SHEAR
(40-45KTS) EACH DAY. HOWEVER H7 TEMPERATURES RANGE FROM 14-16 C. THE
NAM SHOWS ONLY A BRIEF PERIOD AROUND 00Z WHEN CONVECTIVE INHIBITION
DROPS OFF TO AROUND 60 J/KG MAINLY OVER THE NORTHWEST FA. OTHERWISE
CIN VALUES ARE HIGH. SHORTWAVES COMING THROUGH ARE NOT IMPRESSIVE.
FORECAST SOUNDINGS ACROSS THE FA SHOW VERY DRY MID LEVELS.
BOUNDARIES FOR THUNDERSTORMS WILL MAINLY BE THE TROUGH OVER THE
NORTHWEST FA AND THE WARM FRONT WHICH WILL VARY BUT WILL BE
POSITIONED ACROSS THE KANSAS ZONES FROM EAST TO WEST. DUE TO THE
WARM MID LEVEL TEMPERATURES AND CIN HAVE OPTED TO GO WITH LOW POPS
FOR MOST PERIODS.

SPC HAS ISSUED SEVERE WATCH 348 FOR YUMA AND DUNDY COUNTIES
EFFECTIVE UNTIL 14Z SAT. PLAN TO MONITOR STORMS AND POSSIBLY CANCEL
EARLY.

SATELLITE/METARS SHOWING STRATUS OVER THE NORTHWEST FA SO WILL
INCLUDE A MORNING PERIOD OF STRATUS. THIS LOOKS POSSIBLE AGAIN EARLY
SUNDAY MORNING.

GENERALLY FOLLOWED MET GUIDANCE FOR MAX TEMPERATURES WHICH WILL RUN
IN THE MID/UPPER 90S. MAV GUIDANCE WAS USED FOR MIN TEMPERATURES
WITH READINGS IN THE 60S.

.AVIATION...
1057 PM MDT FRI JUN 18 2010

FOR THE 06Z TAFS...VERY COMPLICATED SET OF TAFS. ALL IS DEPENDENT
ON WHERE THE WARM FRONT ENDS UP THROUGH TOMORROW WHICH THE MODELS
DO NOT AGREE ON. MODELS LOOK A LITTLE FURTHER NORTH WITH THE
ACTIVITY AND MAY NOT IMPACT THE KMCK TAF AS EARLIER THOUGHT. SO
PULLED BACK TO JUST A CB MENTION. ALSO DIFFERENCE IN WHERE THE
STRATUS AND FOG END UP. PULLED BACK ON THE CEILING HEIGHT BUT KEPT
IT IN THE MVFR RANGE.

CLOUDS LOOK TO NOT BREAK AT KMCK BUT DID RAISE THEM TO JUST ABOVE
MVFR. AGAIN NOT SURE WHERE THE WARM FRONT WILL END UP PLUS WE MAY
END UP CAPPED FOR MOST OF THE DAY. SO CHOSE TO HANDLE WITH A CB
MENTION BUT AT THIS TIME KMCK LOOKS LIKE THE BEST CHANCE FOR
THUNDERSTORMS TO AFFECT THAT SITE.
