This morning's map is fairly quiet:
Driving east or west away from Houston should be pleasant. Expect mostly sunny skies and dry roads headed toward Dallas, San Antonio or Austin. If you're going to Louisiana, expect much the same.
The only challenge flying from Houston will be the Pacific northwest. A vigorous storm system there is bringing rain and gusty wind to Washington, Oregon and northern California. A front sweeping across the Midwest may spark showers, but flight delays should be minimal. Check http://www.fly.faa.gov/flyfaa/usmap.jsp to find out which major airports around the country have delays.
If you're driving from Houston Wednesday morning, there could be another round of dense fog, so if you can delay leaving until after 9 am. Wherever you're headed, I wish for a pleasant trip and lots of joy when you get where you're going.
