KEY MESSAGES

Updated at 1154 AM CST Tue Jan 27 2026

- The extreme cold threat has ended. However, temperatures will remain well below climatological normals, with the warmest day still around 5 degrees below average.

- A freeze warning is in effect for parts of the southshore excluding Orleans and Jefferson Parish. Places north of the I-10/I-12 corridor still will also get below freezing as well.

- Another significant Arctic outbreak is increasingly likely late Friday into Saturday. A strong cold front will usher in another very cold airmass, with the primary threats being dangerous cold and renewed hazardous conditions across the coastal waters. copy.

SHORT TERM

(This afternoon through Wednesday) Issued at 1154 AM CST Tue Jan 27 2026

Temperatures has moderated slightly today with highs in the upper 40s to low 50s and will continue to moderate slightly through Wednesday. However, this is still well below average for the area for this time of year. There is a freeze warning for parts of the southshore west of Jefferson Parish. Areas along and north of the I-10/I-12 corridor will also be below freezing, this is just due to the local criteria where freeze warnings are issued every instance on the south shore vs the first two instances north of the Lake.

LONG TERM

(Wednesday night through Monday) Issued at 1154 AM CST Tue Jan 27 2026

The slightly warmer temperatures will be short lived as another arctic blast is forecast to move through the area Friday. While the confidence remains generally high that there will be significantly cold temperatures well below normal, there is still about a 10 degree spread in temperatures (from NBM75 to NBM25), so will continue to monitor the trends to see just how cold it gets. In terms of the potential for precipitation, there may be some prefrontal type showers, and maybe a stray storm late Thursday through Friday. However the timing is just not favorable for any type of wintry precipitation. The cold temperatures are not expected until late Friday night/Saturday morning and all the rain will be already well out of the area by the time it arrives. Temperatures will once again slightly moderate going into Monday but it will still remain below average so winter will be hanging around the area for a while.

AVIATION

(18Z TAFS) Issued at 1154 AM CST Tue Jan 27 2026

VFR conditions are forecast for the entire forecast cycle. Winds have decreased and will be much more light and variable at times. No major concerns for any of the local terminals.

MARINE

Issued at 1154 AM CST Tue Jan 27 2026

Hazardous conditions from strong winds will subside today with winds generally remaining at 10 knots or less. The rest of the week will remain benign through Thursday. There is a low chance of some showers and maybe a storm Friday, but as another strong arctic airmass sweeps through the area, winds will strengthen again with small craft advisory conditions likely starting late Friday through most of the weekend.
