WARM FRONTAL BOUNDARY ACROSS NORTHEAST TX IS EXPECTED TO PROVIDE
LIFT FOR CONVECTION LATER THIS AFTERNOON WITH MOVEMENT/DEVELOPMENT
TO THE EAST AND NORTHEAST.  PLENTY OF INSTABILITY AND MOISTURE FOR
THAT...BUT H5 RIDGE PROGGED TO STAY OVER THE AREA THROUGH MOST OF

SLIGHTLY ABOVE GUIDANCE...IN COORDINATION WITH ADJACENT OFFICES.

ON SUNDAY...THE RIDGE MOVES EAST...AND A SIGNICANT SHORTWAVE SWINGS
INTO OK DURING THE DAY. EXPECT CONVECTION TO DEVELOP WITH THE
ASSOCIATED SURFACE FRONT/DRY LINE.  FAR EASTERN OK AND WESTERN AR
SHOULD REMAIN IN THE DEEP MOISTURE ALL DAY AND WILL HAVE BEST
CHANCES OF CONVECTION.  STILL SOME UNCERTAINTY HOW FAR WEST STORMS
WILL DEVLEOP...SO KEPT CHANCE POPS OVER WESTERN PORTIONS OF THE
FORECAST AREA.  SHORTWAVE MOVES THROUGH RAPIDLY...EVEN THOUGH AVN
PROG BRINGS THE FRONT THROUGH MORE SLOWLY.  EXPECT DRY AIR AND MORE
STABLE CONDITIONS TO PREVAIL MONDAY...SO WILL TAKE MENTION OF RAIN
OUT.

THE TAIL END OF THE FRONT NEVER GETS VERY FAR SOUTH...AND BY
TUESDAY...ANOTHER WARMFRONT IS OVER NORTHEAST TEXAS. A SHORTWAVE IS
EXPECTED TO MOVE ALONG THE BOUNDARY AND SPREAD PRECIP NORTHWARD INTO
EASTERN OK AND WESTERN AR. SOME PRECIP COULD BE HEAVY TUESDAY NIGHT.
WILL WATCH THAT SITUATION CLOSELY.
