KEY MESSAGES

Updated at 754 PM CST Sat Jan 10 2026

* A significant cool down is forecast following today's cold front. Low temperatures near or just below freezing are forecast for most places that are generally along/north of the I-10/12 corridor Monday and Tuesday mornings. Any freezing temperatures should only last a few hours. Residents should take action to protect sensitive vegetation and ensure outdoor pets have access to warm shelter.

* According to the National Fire Protection Association, nearly half of all home fires occur between the months of December, January and February, with the increased risk attributed to the use of home heating devices such as portable space heaters and fire places. Those planning to use such devices during this cold snap should be sure to follow all manufacturer safety recommendations such as using a screen and keeping a fire extinguisher near all fire places and ensuring all space heaters are plugged directly into wall outlets and placed on level surfaces at least 3 ft from any flammable materials. * In the wake of the cold front, strong winds and rough seas will develop across the coastal waters. Small craft advisories are in effect from 6p this evening through 6a Monday. Inexperienced mariners, especially those operating smaller vessels should avoid navigating in hazardous conditions.

SHORT TERM

(Tonight through Monday night) Issued at 754 PM CST Sat Jan 10 2026

Well that was a lot of rain within a several hour period mainly during the early morning hours today. The winner was Clinton, MS 0.4NW with 7.08 inches. This data comes from the cooperative obvserver network. The people that do this service are invaluable and they all take a lot time and effort to take and xmit these readings daily and/or when measureable weather is taking place.

After that, we all deserve some tranquil wx for a bit especially with Mardi Gras season already kicked off with Twelfth Night Jan 6th. The season ends with Mardi Gras Day, Feb 17th. We will get some tranquil but cool wx for the next few days but there are some quick changes coming during this week.

LONG TERM

(Tuesday night through Saturday night) Issued at 754 PM CST Sat Jan 10 2026

This week will advertise two systems. The first will be very weak and only produce cloud cover for most with some light rain moving through late Tue night into Wed then the same cool dry conditions come back for late Wed through Fri. Basically, a reinforcing cold front. After this, a quick warming and moistening will occur Fri with the advance of the next frontal system that does look to cause area wide storms with heavy rainfall and another round of severe wx possibilities. This unfortunately occurs by the weekend. Exactly which day and time of day it will bring the worst wx is still up for debate. Unfortunately, a system like this makes it very hard to enjoy the festivities over the weekend. We will continue to look into this to pin down the what, when, where as we get closer to next weekend.

AVIATION

(06Z TAFS) Issued at 754 PM CST Sat Jan 10 2026
