Windy/Strong Storms Likely

An active storm system with an attendant cool front will likely bring showers and storms to Acadiana for Halloween afternoon/evening.

Latest computer model guidance brings storm "prime-time" roughly from 3pm through 10pm Thursday...give or take a few hours.

Gusty southerly winds will increase ahead of this storm system overnight into the daytime hours Thursday with strong enough wind dynamics aloft to support the slight risk of severe storms across Acadiana.

Per the Storm Prediction Center, the main mode of any possible severe weather locally will be in the form of damaging straight line winds associated with a squall line (and "bowing" storms) that will likely form ahead of the cool front. 

A severe thunderstorm "watch" or possibly a tornado "watch" may be issued for portions of Acadiana Thursday so stay tuned for weather updates throughout the day.

Fortunately, the storms will be moving relatively quickly, so flooding is not currently expected, but atmospheric moisture levels will be very high leading to rainfall rates of 1-3" per hour.  

The heaviest storms should last just a few hours, so for now expect rainfalls of 1-2" to be likely with isolated totals 3" or better especially in northwestern portions of Acadiana.

As of Wednesday evening, Flood Watches were posted for much of Eastern Texas, northward through Arkansas, Mississippi and Missouri where 3-5" of rain or more can be expected.

Look for skies to clear with very pleasant weather Friday into the weekend.  Cooler conditions will be likely for Friday and Saturday nights with lows dropping into the lower 50s and mid-upper 40s respectively.  Highs this weekend will be in the 70s.

Quick changes are expected next week with another storm system threatening the area mid-week.
