.DISCUSSION...

ISOLATED THUNDERSTORMS HAVE FORMED OVER THE LAST HOUR BETWEEN PRATT
AND GREAT BEND, ALONG SOUTHWARD SAGGING COLD FRONT. EXPECT ACTIVITY
WILL BE CONFINED TO AN AREA SOUTH OF HIGHWAY 56 AND WEST OF THE
TURNPIKE. WILL LIKELY DISSIPATE BY 9-10 PM WITH DIURNAL COOLING AND
INCREASING CIN. MLCAPES ARE AROUND 500-800 J/KG, AND DEEP LAYER
SHEAR IS ONLY 15-20KT, SO DO NOT EXPECT ANYTHING SEVERE. HOWEVER,
INSTABILITY IS AT LEAST SOMEWHAT MODEST, SO CANNOT RULE OUT SMALL
HAIL, ALONG WITH WINDS OF 40-50 MPH WITH THE STRONGEST CORES. UPDATE
TO ZONES OUT SHORTLY.

MAIN FCST CONCERN IS PRECIP CHANCES TUE NGT-THU

TNGT-MON: ANOTHER COLD FRONT WL SWEEP ACROSS THE CWA TNGT ALBEIT NOT
AS COLD AS THE PREVIOUS FRONT. NEVERTHELESS HIGHS MON WL BE
QUITE A BIT COOLER THAN TDAY. THE MAIN AREA FOR PRECIP WL STAY SW OF
CWA WHERE THETA-E ADVECTION COUPLED WITH UPSLOPE FLOW SHOULD RESULT
IN SOME SHOWERS AND THUNDERSTORMS OVER THE HIGH PLAINS OF OKLAHOMA
AND TEXAS.

MON NGT-WED: WEAK UPPER WAVE WL BEGIN TO MOVE OUT OF THE FOUR
CORNERS REGION AND INTO THE SOUTHERN PLAINS TUE INTO WED. THIS WEAK
SYSTEM APPEAR TO LACK A GOOD JET, AND ISENTROPIC LIFT LOOKS TO BE
LIMITED WITH MOST OF THE LIFT COMING AS A COLD POCKET IN THE 305K
LAYER MOVES ACROSS THE CWA. AM PRETTY CONFIDENT THAT PRECIP WL BE
AFFECTING CWA ON WED, JUST NOT TOO SURE ON THE AREAL EXTENT OF THE
ACTIVITY DUE TO LACK OF GOOD DYNAMICS. SO FOR NOW WL JUST KEEP
CHANCE POPS IN FOR WED. WITH SHOWERS AROUND AND PLENTY OF CLOUD
COVER, LOOK FOR TEMPS TO BE HELD DOWN WED TO JUST BELOW CLIMO.

THU-SUN:
ONCE AGAIN FOUND IT HARD TO IMPROVE TOO MUCH ON THE PREV FCST. MED
RANGE MODELS ARE STILL IN AGREEMENT FOR THU AND FRI IN REGARDS TO
BRINGING A SHORTWAVE THROUGH. THEREFORE WL LEAVE POPS IN FOR THU AND
THU NGHT. STARTING SAT THE UPPER PATTERN BEGINS TO DIFFER BETWEEN
THE GFS AND ECM. THE ECM HAS HAS MORE ENERGY OFF OF THE WEST COAST
SAT THAN THE GFS, THUS RESULTING IN A MORE PUMPED UP RIDGE OVER THE
CENTRAL PLAINS. FOR NOW WL JUST LEAVE SAT AND SUN DRY AND WAIT FOR
BETTER AGREEMENT.
