DISCUSSION...
REFER TO THE 12Z AVIATION FORECAST BELOW...

AVIATION...
VFR CONDITIONS WILL PREVAIL ONCE AGAIN THROUGH THE TAF PERIOD. A
WEAK FRONT WILL LINGER INTO CENTRAL OKLAHOMA...MAKING WINDS
SOMEWHAT ERRATIC. HOWEVER...WIND SPEEDS WILL GENERALLY REMAIN
LIGHT. WINDS WILL SHIFT TO THE SOUTHEAST BY MID TO LATE AFTERNOON
AS THE BOUNDARY LIFTS TO THE NORTH.

PREV DISCUSSION... /ISSUED 327 AM CDT THU JUN 13 2013/

DISCUSSION...
HOT WEATHER WILL CONTINUE TODAY AS UPPER RIDGING REMAINS CENTERED
ON THE TX/OK PANHANDLES AND WESTERN OKLAHOMA. THIS IS WHERE THE
HOTTEST TEMPERATURES ARE EXPECTED TODAY...GENERALLY IN THE LOW
100S. ELSEWHERE...LOW TO MID 90S WILL BE COMMON. THE SAME
GENERALLY PATTERN WILL CONTINUE INTO TOMORROW...THOUGH LOW LEVEL
WESTERLY WINDS MAY YIELD MORE WIDESPREAD TRIPLE DIGIT TEMPS WEST
OF I-35.

A GENERAL PATTERN CHANGE IS STILL EXPECTED BY SATURDAY...AS THE
RIDGE BREAKS DOWN AND SLIDES SOUTHEAST. AS THIS TAKES PLACE...A
LARGE UPPER LOW...NOW LOCATED OVER FAR SOUTH TEXAS AND NORTHERN
MEXICO...WILL GRADUALLY SHIFT NORTHWARD AROUND THE DEPARTING HIGH.
THIS WILL LEAD TO WEAK HEIGHT FALLS AND INCREASING MID LEVEL
MOISTURE. THE RESULT WILL BE MORE WIDESPREAD CLOUDS AND INCREASING
RAIN CHANCES. WE WILL ALSO NOTICE A BREAK IN THE TRIPLE DIGIT
TEMPERATURES. THE UPPER LOW WILL EXIT OKLAHOMA TO THE NORTHEAST BY
LATE SUNDAY...BUT A QUASI ZONAL NORTHWEST FLOW PATTERN WILL
DEVELOP BY EARLY NEXT WEEK. WITH SMALL SCALE RIPPLES IN THE UPPER
FLOW...EXPECT RAIN CHANCES TO PERSIST INTO TUESDAY OF OF NEXT
WEEK. MUCH OF THIS ACTIVITY MAY COME IN THE FORM OF NOCTURNAL
THUNDERSTORM CLUSTERS MONDAY AND TUESDAY NIGHTS.

BY THE MIDDLE TO LATTER PART OF NEXT WEEK...MODELS STRENGTHEN THE
MID LEVER RIDGE OVER THE SOUTHERN PLAINS ONCE AGAIN...LEADING TO A
PERIOD OF HOT AND DRY WEATHER.
