Cold Air Holds Over the Mid-South Through Tuesday, With Rain Chances Returning Midweek

Cold stretch persists into early week

A prolonged push of polar air is expected to keep the Mid-South well below seasonal norms through early next week, with the coldest conditions concentrated in the overnight and pre-dawn hours. Forecast guidance indicates wind chill values dipping into the teens—and, in some locations, single digits—late Sunday through Tuesday, especially across areas north of Interstate 40.

Daytime temperatures are projected to remain subdued through at least Tuesday, with many communities struggling to climb out of the 30s to near 40 during the afternoon. Skies are expected to be mostly dry during this period, but the cold air mass and periodic breezes will reinforce the wintry feel even when sunshine is present.

Why it stays cold: repeated fronts reinforcing polar air

The pattern behind the chill is tied to multiple cold fronts moving through the region in quick succession, limiting the opportunity for a sustained warmup. With each reinforcing shot of colder air, nighttime temperatures remain vulnerable to sharp drops, particularly where winds relax and skies clear enough to allow heat to radiate away from the surface.

Midweek transition: temperatures moderate, moisture returns

By the middle of the work week, forecast trends point to a gradual moderation as winds turn more southerly and Gulf moisture begins to return. That shift increases the likelihood of precipitation by Wednesday and into Thursday, with rain becoming more plausible across a broader part of the Mid-South.

While most of the expected precipitation profile favors plain rain, the timing of returning moisture relative to lingering cold air will be important. If precipitation persists into the colder overnight window or arrives before temperatures fully rebound, a brief mix of rain with light wintry precipitation cannot be ruled out in parts of the region, particularly in colder pockets and areas farther north and east.

What to watch in the forecast

• Overnight and early-morning wind chills from Sunday through Tuesday, with the most hazardous cold concentrated north of I-40.
• The exact timing of the warmup on Wednesday, which will influence whether precipitation is exclusively rain.
• The duration of any precipitation into Wednesday night and Thursday morning, when temperatures are typically lowest.

Bottom line: Cold conditions remain entrenched through Tuesday, with a midweek shift bringing a better chance for rain and a low-end possibility of brief mixed precipitation if cold air overlaps with returning moisture.
