Perfect weather, then weekend showers possible

With luck, we may get a little rain this weekend as another cold front moves through to reinforce the dry Canadian air that cooled things down overnight and put the 90s behind us for a while.

The forecast calls for a 30 percent chance of showers early Sunday morning, with a 40 percent chance of thunderstorms on Sunday afternoon. It's not entirely clear yet how strong that front will be by the time it reaches us, or how much rain we can look for. That should begin to clarify as the weekend nears.

Down in the tropics, Tropical Storm Igor (left of center in photo at right) seems to be staggering a bit, with weakened central winds and a drift to the north toward the Cape Verde Islands.

Forecasters blame wind shear and say the storm could weaken further today. But overall conditions seem favorable for re-development, they say, and Igor is still expected to become a hurricane in the next few days. Even if it does, Igor would not become a threat to the U.S. for quite some time.

Here is the latest advisory. Here is the forecast storm track. And here is the view from orbit.

Also being watched this morning is another area of developing storms in the Windward Islands off the Venezuelan coast. Forecasters give this one a 40 percent chance of becoming a named tropical storm in the next 48 hours.

Remnants of Tropical Storm Hermine continue to plague the Mississippi Valley with heavy rain and flooding. Dallas was struck by a tornado.
