Early Thought On Dean
Dean continues to grow in strength late Wednesday night in the Atlantic Ocean. All signs point to Dean getting quite a bit stronger and possibly turning into a major hurricane. It looks like a high pressure ridge will remain strong over the southern states. As long as this remains true Dean will not be able to turn to the north and will continue to chug off to the west. Obviously this scenario could change by early next week but to be honest the hot high pressure over the region is very well entrenched over the South.
Remember, hurricanes move about in "rivers of air". The storms are pushed around the tropics by other larger weather features. The same high I talked about above is also pushing Erin to the west away from us. So it may be unbearably hot and dry but right now with Dean lurking in the Atlantic...that is a good thing!
Keep an eye on Dean over the next few days as the Caribbean Sea has produced some of the strongest hurricanes on record in mid to late August over the years.

Comparing the forecast track of Dean, a small but soon to be a powerful storm, to Hurricane Gilbert of 1988, both are guided westward across the warm waters of the Caribbean by a strong high pressure system to the North. Eventually Gilbert got around the high pressure, and turned North, as seen in this rainfall map. Lots of rain for west Texas, and into Oklahoma and northward from Gilbert.
Gilbert's main impact was in Mexico, with hundreds of deaths, before turning North.
Could be that Dean will follow in the same track, more or less, since it too is held in it's westward path by high pressure to the North.
Gilbert was a large hurricane in area covered by it's winds.
Dean is starting out small, and probably will stay that way, even though it is forecast to make it to Category 4 before hitting the Yucatán Peninsula, on or about the 20th to 21st of August.
Could mean more rain for Texas from Dean, although the area covered should be less, as long as Dean remains a small hurricane.
