A really warm weather pattern has set up across Acadiana. Highs will climb into the upper 80s around the area under partly cloudy skies. A few spots will try to make a run to 90 degrees today. Rain chances are very low through the afternoon hours, though a stray shower or storm can’t be ruled out. There is a Level 1 (Marginal) risk of severe weather for far northern Evangeline and St. Landry Parishes for a few storms that could produce large hail and damaging winds. Severe weather is not very likely today. Clouds will fill the sky overnight with a few spotty showers possible closer to sunrise. Temperatures will hold in the 70s with a very humid air mass in place.
Today: Sun and clouds mixed. Hot. High: 86°
Tonight: A few showers are possible. Muggy. Low: 71°
Thursday: A few spotty showers and storms, especially in the afternoon. High: 83°
A weak cold front arrives Thursday morning, bringing drier air for the afternoon. Ahead of the front, we could see a few showers and thunderstorms develop. There will be some sunshine in the afternoon, but the front will stall along the coast. The front will be energized by a quick-moving system in the upper levels of the atmosphere overnight Thursday. This will lead to showers and thunderstorms forming along the front. Some of the these storms may be on the strong or severe side. For this reason, a level 1 (Marginal) risk of severe weather has been outlined for most of Acadiana for a few storms that may produce damaging winds and large hail. Overall, the severe threat is very limited. The main focus of our forecast through the next 7 days will be the weekend. The Storm Prediction Center has already outlined all of Acadiana in a severe outlook. A deep dip in the jetstream will combine with a very warm and humid air mass. There appears that wind shear, necessary for severe storms, will be in place. All of these ingredients are leading to a more confident forecast that severe weather will roll through the area Saturday afternoon and continue through Sunday. There appears that there will be two rounds of severe weather possible. The first along a warm front Saturday afternoon/evening and the second along a cold front Sunday morning. Damaging winds, large hail, and tornadoes all look to be possible, so we will be monitoring this situation closely in the coming days.
