BUFFALO, N.Y. — Over the next few hours, a cold front will come sweeping through the region. That will provide a trigger for isolated thunderstorms before 10 p.m. Any thunderstorm that forms has the potential to produce torrential downpours, lightning, and strong wind gusts. 

The interior Southern Tier is most likely to experience a storm, but the Buffalo metro isn't totally in the clear just yet.

A cooler breeze arrives for Friday which will help provide for a gorgeous weekend. Both Saturday and Sunday will feature temperatures near 80° with just a slight chance of a shower Saturday evening.

After that, our focus will turn to the Gulf of Mexico where tropical storm Barry has formed. The storm will likely make landfall in Louisana as a hurricane with exceptional rainfall up to 20 inches and destructive storm surge. The storm will weaken significantly early next week, but some leftover moisture from Barry will continue to lift north which will increase humidity levels and rain chances around WNY. 

We are still watching for the possibility of several very warm, humid days next week, however the now increasing chance for clouds and rain may help cut the worst of the heat off.
