Severe risk Wednesday ahead of a big cool-down

A line of strong storms rolls in Wednesday late afternoon to evening. The cooler air moves in Thursday and sticks around through Halloween weekend.

NEW ORLEANS — We're expecting a risk of severe weather Wednesday afternoon and evening ahead of a potent fall cold front. 

Expect a mostly cloudy, breezy and quiet start to Wednesday. 

A stray storm could form early in the day through lunchtime, but the main line of thunderstorms is set to cross our area later in the day from roughly 4-8 p.m. 

Timing for the worst weather in the New Orleans metro area looks like about 5-7 p.m. 

The line will bring a quick 1-2 inches of rain along with a threat of damaging wind gusts and/or an isolated tornado. 

The line of storms exits quickly by 9 or 10 p.m., and we'll dry out overnight. 

Winds will pick up to make Thursday a clearing, cooler and gusty day. Then mostly sunny skies and a pleasant fall chill will be here through Halloween!

Saturday and Sunday look sunny and gorgeous with chilly mornings and highs barely reaching 70 degrees. 

Halloween should be very pleasant in the lower 70s during the afternoon. Trick-or-treat weather looks pleasant and cool in the 60s after sunset.

Eye on the Tropics

The only spot to watch is one non-tropical area off the northeast coast of the US. It has a 40% chance of of taking on some tropical characteristics this week as it meanders north then east over the Atlantic.
