After another nice and rather pleasant Tuesday for Acadiana, persistent southeasterly winds from the Gulf of Mexico will bring warmer and more humid conditions to the region this week.

And with disturbances aloft enhancing rain chances, there will be some days with good rain chances (starting Thursday) while others will see at least the chance of daytime showers and storms.

In the near term, expect our last relatively cool night for a while...perhaps a long while, with Tuesday morning lows ranging from the mid-50s across northern portions of Acadiana, to upper 50s to lower 60s farther south.

Tuesday will bring more sunshine with a few afternoon fair weather cumulus clouds and accompanied by breezy southeasterly winds arriving from the Gulf of Mexico midday.

Highs Tuesday will rise into the low-mid 80s.

More significant Gulf moisture and humidity will begin streaming in from the Gulf Wednesday, allowing for a few passing showers, roughly at 20-30%.

A disturbance riding west to east in a weak sub-tropical jet stream will encounter deeper Gulf moisture Thursday likely resulting in a good chance of showers and storms.

Our pattern looks to stay locked in Friday through the weekend and beyond, insuring the daily chance of scattered showers and thunderstorms along with warm days in the mid-upper 80s, while night time/morning lows moderate toward the lower 70s.

So a little bit of a pre-summer preview is in store for Acadiana for the bulk of the 10 Day Forecast.
