BATON ROUGE, La. (WAFB) - Old Man Winter will be making a house call Tuesday night, and hopefully, you’re ready to go.
A Hard Freeze Warning goes into effect Tuesday evening for most of the WAFB viewing area and extends into Wednesday morning. That warning covers all of WAFB‘s Mississippi counties, all of the Florida parishes, and extends southward to include Iberville and Ascension parishes. A Hard Freeze Warning means temperatures could dip to 25° or below for a few to several hours.

A Freeze Warning goes into effect for St. Mary, Assumption, St. James, and St. John the Baptist parishes, as well as northern and central sections of Lafourche Parish and northern Terrebonne Parish. Only southern portions of Terrebonne and Lafourche are excluded from the warning. A Freeze Warning means temperatures of 32° are expected for at least a couple of hours.
Temperatures are expected to drop to the mid 20s or lower along the I-10/12 corridor; that includes areas from Lafayette to Baton Rouge to Hammond to Slidell. Freezing temperatures along this stretch could last from 10 to 14 hours. For communities closer to and north of the LA/MS State line, temperatures could drop into the low 20s with freeze durations of 12 to 15 hours or more.
The Storm Team is forecasting a low of 25° for Baton Rouge. That would not only be a record low for Nov. 12 but would also be the lowest reading ever this early in the month.
Fortunately, sunshine through the morning into the early afternoon should warm up most WAFB neighborhoods to around 50° or so Wednesday afternoon. However, clouds will be increasing through the afternoon, effectively ending the warm-up. Skies will be mostly cloudy to cloudy by Wednesday evening.
Those clouds will help keep the low Thursday morning in the upper 30s to low 40s, but they will also bring rain. Rain is likely Thursday, beginning soon after midnight and potentially extending into the pre-dawn hours of Friday as our next cold front rolls into the area. While the day looks to be damp from start to end, Thursday’s front it’s not expected to produce any thunderstorms and rain totals will run at 0.25″ or less for most of the WAFB area. Skies clear through Friday afternoon and evening.
However, a reinforcing shot of cold air behind the front could produce a light freeze Saturday morning for areas along and north of the I-10/12 corridor, and keep temperatures well below normal for the following weekend.
