.DISCUSSION...

TONIGHT
CURRENT THINKING STILL APPEARS TO BE ON TRACK WITH STORMS EXPECTED
TO FIRE IN NORTHERN KS AND BACKBUILD ALONG THE FRONT THIS AFTERNOON.
STEERING WINDS ALOFT WOULD HAVE THE ACTIVITY PROPAGATING TO THE SE
AT 20-25 MPH. EXPECT ACTIVITY TO FILL IN FARILY GOOD ALONG THE FRONT
FOR THE AFTERNOON AND EVENING HRS...BUT WITH LOSS OF DAYTIME HEATING
WOULD EXPECT ACTIVITY TO DECREASE IN COVERAGE SOME AS IT MOVES SE.
SHEAR IS STILL ON THE LOW END...THEREFORE WOULD EXPECT ANY SEVERE
ACTIVITY TO BE MORE ISOLATED AND CONFINED TO CENTRAL KS WHERE BEST
INSTABILITY WILL BE IN PLACE.

MON-TUES
FRONT WAS PREVIOUSLY ADVERTISED TO MOVE THRU THE REGION BUT IT COULD
STALL OUT SOMEWHERE IN SOUTHERN KS...UNLESS CONVECTIVE ACTIVITY CAN
GENERATE A STRONG ENOUGH COLD POOL TO PUSH THE BOUNDARY FURTHER
SOUTH. NEVER THE LESS IT WILL BE A TOUGH CALL DECIDING WHERE ANY
CONVECTIVE ACTIVITY MIGHT TRY AND REDEVELOP ON MONDAY IF AT ALL...OR
IT COULD BE SOME LINGERING ACTIVITY FROM OVERNIGHT DIMINISHING
ACROSS SOUTHERN KS MONDAY MORNING. WILL ONLY CARRY SMALL POPS FOR
SOUTHERN KS AS THIS COULD BE THE MOST LIKELY PLACE FOR A POSSIBLE
SFC BOUNDARY TO SET UP CAMP...HOWEVER UPPER SUPPORT DOES NOT LOOK
TOO FAVORABLE SO PERHAPS ISOLATED TO WIDELY SCATTERED ACTIVITY.

NEXT SYSTEM LOOKS PRETTY DYNAMIC AS ITS ALREADY SHOWING ITSELF ON
WATER VAPOR IMAGERY OVER NORTHERN ALBERTA. THIS SYSTEM WILL QUICKLY
RACE SOUTHWARD ON THE HEALS OF THE SYSTEM NOW MOVING ACROSS NORTH
DAKOTA. IT WILL BE QUITE THE CHALLENGE FOR TEMP FCSTING ON TUES AS A
STRONG THERMAL GRADIENT WILL PROBABLY EXIST WITH TEMPS IN THE COOLER
60S NORTH OF THE BOUNDARY AND 80S TO THE SOUTH...HOWEVER THERE
SHOULD BE SOME DECENT CLOUDINESS THAT WILL ALSO NEED TO BE FACTORED
INTO THE EQUATION. IT APPEARS THAT WE WILL SEE ANOTHER DECENT CHANCE
OF PRECIP SPREADING ACROSS CENTRAL AND SOUTHERN KS. GOING POPS SEEM
TO MATCH UP WITH NEIGHBORS NICELY SO WILL ONLY MAKE A FEW MINOR
TWEAKS.

WED
COOL CANADIAN AIRMASS WILL POUR SOUTHWARD INTO KS WITH PRECIP COMING
TO AN END ACROSS SOUTHERN KS. AFTERNOON HIGHS WILL BE SOME 15-20
DEGREES BELOW AVERAGE EVEN WITH FULL SUN. A FEW RECORDS TEMPS OF
SOME KIND COULD POSSIBLY BE BROKEN...STAY TUNED.

EXTENDED: THUR-SUN
NO BIG CHANGES MADE AS MODIFICATION OF COOL CANADIAN AIRMASS
UNDERGOES A SLOW WARMING PROCESS. TEMPS ARE STILL EXPECTED TO REMAIN
BELOW NORMAL FOR AUGUST STANDARDS.

ANOTHER IMPULSE WILL SLIDE S ACROSS THE AREA ON THURSDAY BUT
MOISTURE APPEARS TO BE SCOURED OUT FROM TUESDAYS SYSTEM. SO IT LOOKS
LIKE IT WILL ONLY BE AN INCREASE OF CLOUDS ON THURSDAY...WHICH COULD
HAMPER TEMPS FURTHER. MED RANGE MODEL SOLUTIONS HAVE A WEAK SIGNAL
OF UPPER RIDGE FLATTENING OUT BY NEXT WEEKEND WITH A IMPULSE SLIDING
W ACROSS THE ROCKIES. THE GFS MAJORITY IN ITS ENSEMBLE MEMBERS ARE
STILL IN FAVOR OF UPPER RIDGE HANGING TOUGH WHILE CANADIAN ENSEMBLE
MEMBERS INDICATE THAT UPPER RIDGE WILL BREAK DOWN. IF THE SIGNAL
FROM CANADIAN/ECM SOLUTIONS REMAIN CONSISTENT THEN I COULD SEE SOME
CHANCES OF PRECIP INSERTED BY LATER SHIFTS. JUST TOO MUCH
UNCERTAINTY TO TOSS SOMETHING IN FOR NEXT SAT OR SUN AT THIS
JUNCTURE.
