Windy Saturday becoming stormy early Sunday

Posted: Updated:

The weather pattern will become dynamic across Acadiana this weekend with a windy and warm Saturday followed by a wet, and potentially stormy Sunday.

In the near term, rain chances will stay near 20% or less overnight Friday into the day Saturday with temperatures continuing 15-20 degrees above normal.

After a mostly cloudy morning start near 70, highs Saturday will be in the lower 80s with a few intervals of afternoon sun possible.

The story Saturday will be windy conditions with southerly winds increasing to 18-25 mph with gusts in the 35 mph range from the late morning through the afternoon, and quite possibly evening hours.

A slow-moving cool front will approach the area during the very late night hours Saturday, and likely closer to daybreak Sunday, with thunderstorms likely along this boundary through the morning hours.

Per the Storm Prediction Center, there will be a marginal risk of a few isolated severe storms that could produce damaging winds and/or an isolated tornado.

The window for any severe weather locally will roughly from well after midnight Saturday through the early morning hours Sunday, perhaps lasting into the  through early afternoon into Iberia, St Mary and Lower St Martin Parishes.

The main severe storm dynamics however, will be earlier and well to the north of the area, especially across Arkansas and surrounding states, where an "enhanced risk" is outlined. Wind damaging storms and a few strong/damaging tornadoes will be possible there, primarily Saturday afternoon and evening.

Although the front should make it into the Gulf of Mexico Sunday afternoon, there will continue to be ample upper atmospheric conditions that will allow for periods of rain and a few embedded storms to continue for much of the day Sunday.

Rainfall totals per the RPM and European Models including the Weather Prediction Centers estimates, will be in the 1.5-2.5" range for most of Acadiana.

Isolated rain totals of up to 3-4" could be possible, especially farther to the north. Flooding is not expected area-wide, however there could be one or two trouble spots that may see some localized run-off issues and perhaps some street flooding.

Temperatures Sunday should slowly cool (from the northwest to the southeast) into the 60s perhaps dropping into the upper 50s Sunday night into Monday morning.

Showers should end by Sunday evening with a fairly nice Monday shaping up as temperatures rebound back into the low to mid-70s.

The same weekend frontal boundary will likely "back-up" from the Gulf Tuesday, and along with an upper level disturbance, will likely result in a good chance of showers and perhaps some strong thunderstorms by late in the day.

Acadiana should get a little bit of a break again Wednesday, before a more "definitive" front arrives Thursday.

This promises to bring cooler temperatures (back to almost near normal) and mostly sunny skies next Friday into the following weekend.
