FIRST ALERT FORECAST: Mainly dry Friday; expect fall-like temps Saturday, Sunday mornings

FIRST ALERT FORECAST: Thursday, Sept. 17 - 10 p.m.

BATON ROUGE, La. (WAFB) - Thursday was marked by considerable cloudiness, but conditions stayed dry across the WAFB region area. Afternoon temperatures reached the upper 80°s for many WAFB neighborhoods, but it was a fairly pleasant afternoon given the northerly breezes and the reasonably low humidity.

Friday shapes up to be a mostly cloudy day, but one that’s mainly dry and a bit cooler too. After a morning start near 70° to the low 70°s for the capital area, highs Friday will only reach the mid 80°s. Northerly winds will keep the humidity relatively low again. While the First Alert Storm Team can’t guarantee a totally rain-free Friday for the viewing area, rain chances for most of the area are set at 10% or less, with a slightly higher chance of rain along and near the coast.

We get to enjoy a fall feel to the air this weekend as more of the cooler and less humid air filters into the state from the north. Morning lows Saturday and Sunday are expected to be in the 60°s for many WAFB neighborhoods, with afternoon highs in the low 80°s both days. Like Friday, we could see a spotty shower or two Saturday, with rain chances ever so slightly higher along the coast. Most of us will stay dry Sunday as well, although rain chances get nudged up to 20% for most WAFB communities and 30% along the coast.

At 6 p.m. Thursday, the National Hurricane Center (NHC) upgraded Invest 90L to Tropical Depression #22. The depression is located in the southwestern Gulf of Mexico and becomes the Gulf’s sixth tropical cyclone of the 2020 season. The NHC forecast calls for TD #22 to become Tropical Storm Wilfred within the next 12 to 24 hours as the storm slowly moves northeast.

While the forecast has Wilfred heading towards Louisiana over the next two days, model consensus has the storm making a turn to the west Saturday and remaining in the western Gulf through the weekend. While confidence in the westward turn is relatively high, the fate of soon-to-be Wilfred is far less certain into next week.

For the time being, however, Louisiana residents can relax and enjoy the local fall feel to the weekend weather. Morning lows will be in the 60°s and highs in the low to mid 80°s Saturday and Sunday across most of the WAFB viewing area. While the weekend won’t be entirely rain-free, the Storm Team is calling for just spotty showers Saturday and only isolated rains, mainly nearer to the coast, on Sunday.

The outlook for this Gulf system into next week remains very muddled, however. We will simply have to wait until Sunday and Monday, Sept. 21 before we get a better handle on what the system might become and where it might be headed.
