Hurricane Issac is pushing a lot of moisture out of the Gulf of Mexico. Friday, there's going to be a really good chance of thunderstorms from just west of Hot Springs and back to the east, with the squall line extending out of the gulf northward into Missouri. This is expected to be clearing to the northeast from the south sometime Friday night.
If you're traveling into Hot Springs on Friday, be prepared for wet weather travel.
PLEASE BE CAREFUL!
By the way, the forecast for Saturday and Sunday is sunny and little chance of rain. I think the temperature should be unseasonably cool from the rainfall; a very welcome thing . . .
