A cold front is passing through the region on Thursday which is bringing much cooler and drier air for a few days. Overnight lows will be falling into the 30s and 40s, with even some areas breaking into the upper 20s. This is quite the change from the past few days. Wednesday and Thursday morning lows in Baton Rouge broke the records for warmest low at 67°F and 69°F, respectively.

Breezy winds from the northwest around 10-15 mph are advecting colder air that originated from the the Northern Pacific Ocean earlier this week. Cloud cover into tonight will help trap some colder air near the surface with overnight lows into the upper 30s and lower 40s south.

With increased winds, the wind chills will be around 5-8 degrees colder than the actual temperatures. Wearing a few layers will be a good idea during the first half of the day.

During the afternoon on Friday, skies will clear during the day to bring some sunshine, but high temperatures will remain in the low-to-mid 50s.

The coldest night will arrive Friday night into Saturday morning. Winds will weaken by then and skies will be clear. These conditions will help radiational cooling take effect where lows might overachieve some guidance. Low temperatures will be near or below freezing in some places. Areas north into Mississippi could see lows into the upper 20s with low 30s near and south of the 10 and 12 corridor.

With a light freeze expected Friday night, it would be a good idea to bring in your pets and any sensitive plants.

Looking ahead, temperatures will begin to warm up next week with highs reaching into the 70s and increased rain chances ahead of the next frontal system late in the week.
