Any rain for the weekend?
A boundary moving to the south should be enough to spark a few scattered downpours Sunday afternoon / early evening. Some of those thunderstorms coming in from the northeast could turn severe with gusty winds and large hail. We are currently calling for a 30% chance of shower and thunderstorms.

How about next week?
As high pressure to our west drifts a bit more north and west we'll bring back in enough moisture to the area for a few showers and storms through early next week.

Is it true that a tropical system could develop in the Gulf of Mexico next week?
Yes, it is possible low pressure will spin up in the western half of the Gulf next week, but it is way too early to know if we'll get any impacts here should one form. You can stay aware and informed on what's happening in the tropics by visiting abc13.com/tropicalupdate.
