A change from the balmy pattern is in store for Acadiana Tuesday evening/night as a strong cold front rolls across the region.
A vigorous storm system will advance through the Great Plains Tuesday engendering strong southerly winds across Acadiana. Winds will increase from the south at 20-30mph Tuesday with gusts possibly reaching 35-40mph Tuesday afternoon.
Thunderstorms will erupt across Eastern Texas Tuesday afternoon and will advance eastward into Louisiana and Mississippi Tuesday night.
The Storm Prediction Center (SPC) is indicating a potentially dangerous set-up for the risk of severe storms producing damaging winds and isolated tornadoes for the northern part of the state into Mississippi.
Low and mid-level wind dynamics will increase across Acadiana Tuesday afternoon evening producing a favorable environment for rotating storms to develop Tuesday night.
The greatest risk for severe weather Tuesday night will be from Central Louisiana northeastward through Mississippi with the SPC highlighting these areas for a "moderate" risk. This area could see several "significant" tornadoes of EF2 strength or greater.
Meanwhile farther south into Acadiana, the greatest risk of severe weather would be in the form of damaging winds and possibly a few isolated tornadoes. Wind gusts in strong storms could produce gusts of 60mph or greater.
There is a good chance that portions if not all of Acadiana may be under a severe thunderstorm or tornado watch Tuesday evening/night.
Storms will come to an abrupt end by daybreak Wednesday with dry, breezy and seasonably cooler conditions likely for the rest of the week and into the weekend.
Highs will be closer to the more "normal" 60s with lows ranging in the more seasonable and chilly upper 30s to low-mid 40s into the weekend which will be a stark contrast to temperatures Tuesday that will flirt with the upper 70s to near 80 well inland.
