MONTGOMERY, Ala. (WSFA) - Shower and thunderstorm chances are on their way up as we begin the first full week of September. That’s courtesy of higher humidity, some tropical moisture and a pair of frontal boundaries... the chance for rain and rumbles will be right around 40-50% tomorrow and we anticipate most activity will occur during the peak heating hours of each day. Expect the sky to be partly cloudy when it’s not actively raining.

Scattered showers and storms are expected Tuesday.

High temperatures each day will be near 90 degrees with that summertime mugginess back in the forecast.

Then our eyes turn to what could be a weak tropical system in the Gulf of Mexico. There is a lot of model disagreement on what happens with a disturbance down in the southern Gulf, but the National Hurricane Center has given it a 30% chance of developing into at least a tropical depression as it moves toward the northern Gulf Coast and into the Southeast.

There's a low 30% chance of tropical development over the next 5 days, but even without any...

Regardless of whether or not it develops into an official tropical system, our rain chances and coverage will go up on Wednesday. That’s due to a surge of tropical moisture.

That disturbance will push away by Thursday, but a secondary frontal boundary could fuel at least isolated showers and thunderstorms on Thursday.

Coverage of rain remains elevated through midweek, then lower humidity returns with sunshine!

Beyond that, though, things are looking phenomenal! We’re in for much lower humidity, plentiful sunshine, highs in the 80s to around 90, and lows in the 60s!

That pattern should carry us into early next week!

The humidity will fall off big-time to end the week.
