.DISCUSSION...

SATELLITE IMAGERY PUTS THE CENTER OF T.S. IKE RIGHT OVER

A SEVERE MENTION IN THE GRIDS TO COVER THIS THROUGH TONIGHT.  LATEST

HURRICANE IKE WILL CONTINUE TO WEAKEN AND MOVE NORTH ACROSS EAST

ONGOING ACROSS SOUTHWEST ARKANSAS...NORTHEAST TEXAS...AND NORTH

CONDITIONS EXPECTED THROUGHOUT MUCH OF THIS NEXT WEEK.
