BUTTE – SW flow continues to transport limited moisture into Montana and a few short-lived thunderstorms are possible daily through the weekend. East of the divide will have a slightly better chance for a stronger thunderstorm Thursday and Friday afternoon.
The big weather story again today is the storm system in the Gulf of Mexico. A slow moving now tropical storm called “Barry” is barely moving just off the Louisiana coast. This storm system could strengthen into a category 1 hurricane by Friday morning and will lift up into the Gulf states this weekend producing incredible rainfall between 5″ to 20″.
The above on demand STORMTracker video forecast will update you on Tropical Storm Barry and the timing of possible thunderstorms Thursday and Friday afternoon.
