Tuesday will bring a mix of sun and clouds, with highs in the mid to upper 70s and a few spots near 80 degrees.
Spotty showers are possible, with the best chance for rain overnight Tuesday into Wednesday morning. Rain totals will generally be less than a quarter of an inch.
Wednesday’s highs will reach the upper 70s to near 80 ahead of a strong cold front arriving Thursday.
A dip in the jet stream will send colder air toward the Gulf Coast, bringing temperatures 5 to 15 degrees or more below average in some areas. Across south Louisiana and south Mississippi, highs will stay in the 60s Friday through Sunday, with Saturday expected to be the coldest morning.
Projected morning lows:
- Friday: Lower 40s Northshore; lower 50s South Shore
- Saturday: Mid to upper 30s Northshore; upper 40s South Shore
- Sunday: Upper 30s to lower 40s Northshore; lower 50s South Shore
Patchy frost is possible Saturday morning in rural areas north of Lake Pontchartrain, depending in part on how much winds relax. Frost isn’t guaranteed, but gardeners may want to protect tropical plants. Farther north, a first frost or freeze is possible, especially north of the I-20 corridor from Birmingham to Atlanta.
A warm-up returns by the middle of next week, with highs back in the mid-70s.
