AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OK
1122 AM CDT THU APR 10 2008
.DISCUSSION...
THE WEATHER HAS PRETTY MUCH QUIETED DOWN. THERE IS ONLY
A SMALL CHANCE OF ADDITIONAL THUNDERSTORMS ACROSS THE
EASTERN AND NORTHERN PARTS OF THE AREA IN ASSOCATION WITH
THE BOUNDARIES THAT ARE MOVING ACROSS THE AREA. THE ONE
OVER EASTERN OKLAHOMA IS NOT A TRUE DRY LINE ANY MORE BUT
STILL MAY BRING SOME LIFT TO WESTERN ARKANSAS THIS AFTERNOON.
THE NEXT ONE WILL BE A COLD FRONT COMING FROM THE NORTHWEST
WHICH WILL SHIFT THE WINDS AGAIN AND THAT WILL AFFECT NORTHEAST
OKLAHOMA LATE THIS AFTERNOON. THE REMAINING INSTABILITY PRETTY
MUCH GOES AWAY THIS EVENING SO TONIGHT SHOULD BE DRY.
