After that gorgeous Thursday afternoon under blue skies and sunshine, we can expect clear skies to continue through the evening and overnight with temperatures dropping through the 60°s and 50°s. The thermometer bottoms-out in the mid 40°s for an almost chilly Friday sunrise for the Red Stick. It’s sunshine through the day for Friday: a mostly sunny day and less humid with a daytime high around 70° to the lower 70°s for the Capital region. Everything looks fine for Friday evening’s "Live After Five" in downtown Baton Rouge with temperatures easing their way down into the 60°s while "Werewolf" delivers its 1980s cover music.

Expect partly to mostly cloudy skies for Saturday morning and plan for a sun/cloud mix to mostly cloudy skies through the day. Afternoon highs will climb into the mid to upper 70°s and you will likely notice a slight uptick in humidity but Saturday stays mainly-dry through the afternoon and into the early evening. The First Alert Forecast introduces a 30% chance of rain before midnight on Saturday with rain chances rising steadily during Sunday’s pre-dawn hours. A storm system will be rolling across the Bayou State on Sunday delivering widespread rain - just about everyone gets wet. The NWS Storm Prediction Center has now placed almost all of the WAFB region under a "Marginal Risk" for severe storms through at least 7 a.m. Sunday. The primary threat will be damaging t-storms winds.

The latest model guidance remains a bit mixed as to the timing of Sunday’s rains but there is agreement that the greatest potential for heavy rain and strong storms will be during the morning. The chief difference among the models is about the timing for when the rains will end. For now, we will post a First Alert heads-up for Sunday morning into the early afternoon, with rains expected to taper off through the afternoon and into the evening. Most neighborhoods can expect to receive 0.5” to 1.0” of rain with totals possibly running as much as 1.0” to 1.5” along the north of the LA/MS state line. Lows on Sunday morning will be in the low to mid 60°s with highs climbing into the mid 70°s.

While the core of Sunday’s rainmaker should be well east of the WAFB viewing area by early Monday, we could still be dealing with some lingering clouds into Monday. Expect a mainly-dry Monday under mostly cloudy skies to a sun/cloud mix with sunrise temperatures in the low to mid 50°s and afternoon highs in the low 70°s. The First Alert extended outlook for Tuesday, Wednesday, and Thursday calls for fair skies for all three days with a warming trend that takes afternoon highs from the mid 70°s on Tuesday up to around 80° or so for Wednesday and Thursday.
