Tuesday’s rains arrived a little sooner in the afternoon and came with some locally heavy downpours. None of the storms were deemed as severe, but some of the brief downpours likely caused some temporary pooling along area roads.

And as is typical in the summer, not everyone across the WAFB area received rain, but Doppler radar estimates show a few neighborhoods received well over 1" of rain. This is very typical for our summer weather pattern, with some getting none, some getting a little, and others getting a little too much. The good news, however, is the earlier arrival of Tuesday’s rains took some of the punch out of the atmosphere and that should lead to a relatively quiet evening commute (although not necessarily entirely rain-free).

Area rains will subside through the evening and into the overnight, but clouds linger. Temperatures will be down in the 70s for much of the evening and stay in the 70s overnight.

Wednesday morning daybreak temperatures will be in the low to mid 70s for metro Baton Rouge, with low clouds, a muggy haze, and maybe a patch or two of light fog for the early morning drive. We can’t guarantee an entirely dry morning commute, but any showers that do develop in the early morning hours will be light and spotty.

Our forecast this week has been promoting a downward trend in rain chances as we head towards the weekend. That general pattern is still expected, but the drop-off now looks to be a little slower than we were previously thinking.

Our First Alert Forecast carries a 50/50 chance of rain on Wednesday, composed of mainly afternoon showers and thunderstorms. We will then go with a 40 percent chance of rain on Thursday. Expect highs for both days in the upper 80s to near 90° before the rains and clouds arrive to knock the temperatures back during the afternoons.

We still favor a drier outlook for Friday and the weekend. Our latest forecast calls for 30 percent chance of afternoon showers on Friday, 20 to 30 percent on Saturday, and just 20 percent on Sunday. Highs for all three days will be around 90° to the low 90s. Gulf humidity will still be a part of the daily weather ingredients even if the rains are not, so expect heat index readings in the middle of the afternoon to approach or even top the century mark for all three days. Remember, the heat index is the "feels like" temperature in the shade. Exposure to the midday sun can add another 5° to 10° or more to that apparent temperature.

Into next week, we will continue with rain chances at 20 to 30 percent for Monday and Tuesday.

The National Hurricane Center (NHC) has stopped formal tracking of the disturbance that was in the western Gulf as the core of the system has moved into coastal Texas. That system has been slow to move over the last 24 to 48 hours and the NWS Weather Prediction Center is still suggesting localized storm totals could exceed 10” in places along and near the Texas Gulf Coast.

Elsewhere in the tropics, the NHC is posting the all clear for the time being.
