FIRST ALERT FORECAST: BIG changes coming; Winter Weather Advisory for some

BATON ROUGE, LA (WAFB) - On this last Monday in January, enjoy “an average” winter day throughout southeast Louisiana/southwest Mississippi, but that will be changing BIG time within the next 24 to 48 hours.

FIRST ALERT FORECAST: Monday, January 28, 2019, 9News at Noon

This morning, temperatures were chilly but seasonally in the lower 40s and today, expect partly cloudy skies, southwest winds, and high in the mid-60s.

Overnight is when our weather will get very interesting. We’re looking at light rain possibly mixed with snow in the predawn hours, but little or no accumulation expected.

However, the southwest counties of Mississippi (Wilkinson, Amite, Pike, and Walthall) will be under a “Winter Weather Advisory” from 3 a.m. until 9 a.m. Tuesday for the potential of ½” to 1” of snow, plus significant winds chills.

Locally, Tuesday will be much colder and windy (low wind chills), with a daytime high only in the low/mid-40s.

Then, prepare for the onset of the coldest air of the season Tuesday night/Wednesday morning when the temperature drops into the mid-20s.
