Special Weather Statement issued January 25 at 2:22PM CST by NWS New Orleans LA

Effective: Sun January 25, 2026, 2:22 PM
Expires: Mon January 26, 2026, 6:00 AM

Extremely cold temperatures that are well below freezing will be in place for several hours tonight into tomorrow morning. Lows will fall into the upper teens and lower 20s north of the I-10 corridor and the mid 20s south of the I-10 corridor for several hours tonight. Wind chills will fall into the single digits north of the I-10 corridor and the teens south of the I-10 corridor late tonight into tomorrow morning. These extremely cold temperatures are the primary threat for tonight into tomorrow morning. A secondary and much less likely concern will be any black ice forming on elevated roadways. Rainfall will be coming to an end on the Mississippi and Louisiana coasts by 4 PM. Strong northwest winds of 15 to 20 mph with gusts to 25 mph will help to dry off the roads before the below freezing temperatures set in. However, areas north and west of a Baton Rouge to Greensburg to McComb line saw freezing rain occur earlier today. This is the only area where ice will continue to be a concern on elevated roadways and bridges through tomorrow morning. A review of soil temperature observations indicate that ground temperatures reported in the area remain in the upper 50s and lower 60s this afternoon, so even in areas that experienced freezing rain today there was no ice accumulation on the ground or non-elevated roadways. The bottom line is that for areas including metro New Orleans, southern and eastern parts of metro Baton Rouge, the Northshore, coastal Mississippi, and coastal Louisiana, black ice is not a major concern given the expected dry road conditions and warm ground temperatures. For northern metro Baton Rouge and areas of southwest Mississippi to the west of I-55, lingering ice will be a concern on elevated roadways and bridges through tomorrow morning.
