A Dense Fog Advisory goes into effect for the entire WAFB region at 6 p.m. Monday evening, but area traffic cameras and visibility reports from numerous regional weather stations show that visibility is already less than a mile for some areas as early as mid-afternoon Monday.
The week’s big weather story is centered around Friday and Saturday. The Storm Team has been talking about a severe weather threat during the Friday/Saturday time frame since last week and that concern continues.
Showers (along with a few thunderstorms) could begin early Sunday, becoming widespread by the afternoon. The cold front is not expected to cross the Baton Rouge metro area until the latter half of the day.
A cold front will move from northwest to southeast across Louisiana Sunday, delivering widespread rain accompanied by a few thunderstorms. Severe weather is not a significant concern and most WAFB neighborhoods will get less than 1″ of rain with this system.
Monday’s guidance indicated a cold front was expected to arrive in the WAFB region during the late Sunday/early Monday time frame (Dec. 29 through 30). New guidance now bumps the arrival time up by more than 12 hours, bringing the system into the WAFB area early Sunday.
After a Saturday morning start near 50° for the Red Stick, the Storm Team does expect the clouds to thin as the day progresses. Sunday starts off with mainly clear skies and daybreak temperatures in the upper 40s to near 50°.
Scattered, mainly light showers will continue into Tuesday evening with the rains ending after midnight. Temperatures will slowly fall from Tuesday evening’s mid to upper 40s down to near 40° for Wednesday’s sunrise, with clearing skies through Wednesday morning.
The Storm Team is still expecting a cold front to bring scattered rains to the WAFB area Friday. Some of the more recent computer model runs suggest the system may arrive a bit later than we anticipated Tuesday.
Get ready for a light, brief frost or freeze to start off the morning. Freeze duration for the capital region will probably be just a couple of hours at most, while temperatures could be at or below 32° for upwards of four hours or more along and north of the LA/MS state line.
The First Alert Forecast maintains scattered passing showers through the evening and beyond midnight, with rain chances then ramping up considerably between 3 and 9 a.m. Wednesday as a cold front sweeps through the area from the northwest.
Isolated showers will begin to pop up across portions of the WAFB area Friday afternoon ahead of an advancing cold front. That front is expected to get into the Baton Rouge area sometime near midnight or very early Saturday morning, bringing widespread rains, accompanied by a few t-storms.
