DISCUSSION...
STORMS HAVE BEEN SLOW TO DEVELOP TODAY HOWEVER, THERE WILL REMAIN
ISOLATED CHANCES THROUGH THIS EVENING.

TOMORROW WILL BE THE START OF A DRYING TREND WHICH WILL EXTEND
THROUGH THE UPCOMING WEEKEND. HIGH TEMPERATURES WILL BE PLEASANTLY IN
THE UPPER 70S AND LOW 80S.

THE START OF NEXT WEEK COULD SEE THE RETURN OF PRECIPITATION TO THE
PANHANDLES AS A CLOSED LOW APPROACHES. MODELS ARE IN SOME
DISAGREEMENT AS TO THE EXACT TIMING ON THE START OF PRECIP. HAVE KEPT
THE POPS GOING THROUGH TUESDAY BUT HAVE STARTED THEM ABOUT 12 HOURS
PRIOR TO THE PREVIOUS FORECAST. MEDIUM RANGE MODELS HAVE SHOWN A WEAK
SHORTWAVE EJECT AROUND THE CLOSED LOW DURING THE DAY MONDAY SO FELT
CONFIDENT ENOUGH TO INSERT MENTION AT THIS TIME. WILL CONTINUE TO
MONITOR THIS PORTION OF THE FORECAST AS CHANGES WILL BE LIKELY. LATE
MONDAY NIGHT/EARLY TUESDAY MORNING WILL SEE A PACIFIC COLD FRONT
MOVE ACROSS THE PANHANDLES. THIS WONT HAVE TOO MUCH EFFECT ON THE
HIGH TEMPERATURES BUT SHOULD KNOCK THEM DOWN A COUPLE OF DEGREES.
MEDIUM RANGE MODELS DISAGREE GOING INTO THE MIDDLE OF NEXT WEEK ON
THE POSITION OF THE COLD FRONT ONCE IT STALLS. THE IF THE FRONT
STALLS OVER THE AREA THEN POPS MAY NEED TO BE INSERTED BUT IF THE
FRONT IS ABLE TO PUSH SOUTHEAST OF THE AREA THEN WE SHOULD SEE DRY
CONDITIONS.
