AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
500 AM CDT THU APR 17 2014

.DISCUSSION...
CURRENTLY...WEAK SFC COLD FRONT IS MOVING VERY SLOWLY TO THE
SOUTH AND IS LOCATED FROM NEAR STILLWATER WSW TO NEAR
CHEYENNE. 800-700 MB DEFORMATION ZONE IS APPARENT ACROSS SOUTH
CENTRAL KS RIGHT NOW AND WILL CONTINUE TO SLIDE SOUTH AS UPPER
TROUGH APPROACHES. THIS WILL BE ONE AREA OF LIFT/FOCUS FOR SHOWER
DEVELOPMENT. THE OTHER WILL ACCOMPANY THE VORT MAX AND MID LEVEL
ISENTROPIC ASCENT ACROSS W/SW OK THROUGH THE AFTERNOON HOURS AS
THE SFC FRONT DRAGS SOUTHWARD. THE STRONGEST LIFT WILL LIKELY TAKE
PLACE FROM AROUND 18-21Z NEAR SW OK. COULD SEE CLOSE TO 0.5 INCH
SOMEWHERE OUT WEST...BUT AMOUNTS WILL LIKELY REMAIN WELL BELOW
THIS FOR THE REST OF THE FA TODAY. DRIZZLE MAY CONTINUE NEAR
WESTERN N TX DURING THE OVERNIGHT HOURS AS SUBTLE ISENTROPIC
ASCENT CONTINUES THERE. RAIN CHCS WILL COME TO AN END FOR THE
ENTIRE AREA FRIDAY AS SHORTWAVE RIDGING REPLACES THE PASSING
TROUGH. HIGHS WILL REBOUND BACK INTO THE 70S FRI AFTERNOON...WHICH
IS AVG.

SATURDAY LOOKS LIKE A FAIRLY NICE DAY AS WELL WITH HIGHS SLIGHTLY
ABOVE AVG...BUT SOUTH WINDS WILL INCREASE AGAIN AS A LEE LOW
DEVELOPS AHEAD OF THE NEXT SIGNIFICANT UPPER LOW TRAVERSING THE
SOUTHWEST. MOST OF THE DETERMINISTIC GUIDANCE INDICATE AN INITIAL
SHORTWAVE TROUGH WILL MOVE OVER THE TX PANHANDLE AND INTO NORTH
CENTRAL OK AROUND 00Z SUN. DO NOT EXPECT POPS WITH THIS FEATURE
CONSIDERING MOISTURE PROFILES AND CAPPED ENVIRONMENT.
HOWEVER...THE SECOND WAVE ON ITS HEELS WILL RESULT IN POPS
STARTING OUT WEST AND SPREADING EAST DURING EASTER SUNDAY MORNING.
FINALLY...THE MAIN WAVE WILL PASS OVER CENTRAL OK DURING THE LATE
AFTERNOON AND OVERNIGHT HOURS ON SUNDAY FROM WEST TO EAST. WILL
KEEP HIGH CHC TO LIKELY POPS GOING DURING THIS TIME PERIOD. STILL
EXPECT SOME STRONG TO PERHAPS A FEW SEVERE STORMS TO DEVELOP...BUT
THESE SHOULD REMAIN MARGINAL WITH ONLY MODEST INSTABILITY AND
DEEP LAYER SHEAR ANTICIPATED. HAIL WILL LIKELY BE THE MAIN THREAT.
THUNDER/RAIN CHANCES SHIFT EASTWARD WITH THE TROUGH MONDAY...BUT
THERE COULD BE SOME LINGERING MOIST CONVECTION ACROSS THE SE WHERE
A STATIONARY BOUNDARY WILL BE.

THE PATTERN THEN SHIFTS TO RIDGING OVER THE PLAINS NEXT WEEK AHEAD
OF A DEEP TROUGH DIGGING OVER THE NPAC. TEMPS WILL CLIMB WELL
ABOVE NORMAL TUES-THURS. LOW LEVEL MOISTURE WILL QUICKLY RETURN
AHEAD OF THE PREVIOUSLY MENTIONED FEATURE AS IT NEARS THE CENTRAL
AND SOUTHERN ROCKIES WED. HAVE INTRODUCED ISOLATED THUNDER FOR WED
AFT/EVE OUT WEST NEAR A POSSIBLE DRYLINE...BUT WILL KEEP THURS DRY
FOR NOW.
