Texas, Louisiana, Mississippi, Alabama and Georgia to Feel Arctic Blast as Temperatures Crash 30–40 Degrees Across Central and Eastern U.S.
UNITED STATES — A powerful Arctic blast is poised to sweep across the central and eastern United States this weekend into early next week, sending temperatures plunging by as much as 30 to 40 degrees within 24 hours for tens of millions of Americans.
Forecast temperature anomaly maps show a massive surge of below-average air diving south from Canada into the Plains, Midwest, Deep South and eventually the Gulf Coast.
Where the Coldest Air Will Hit
The core of the cold anomaly — shown in deep purples and blues — stretches from:
- North Dakota
- Minnesota
- Wisconsin
- Illinois
- Missouri
- Indiana
- Michigan
But the cold will not stop there.
By early next week, significantly below-normal temperatures will extend as far south as:
- Texas
- Louisiana
- Mississippi
- Alabama
- Georgia
Freezing temperatures are possible along portions of the Gulf Coast, marking a sharp reversal from recent springlike warmth.
A 40-Degree Drop in 24 Hours
Ahead of the front, many areas will see mild to warm conditions. Once the Arctic air arrives, temperatures could tumble rapidly.
Some locations may experience:
- Afternoon highs in the 60s or 70s
- Followed by overnight lows in the 20s or 30s
- A 30–40 degree swing in less than a day
Such rapid drops can create stress on infrastructure, agriculture and vulnerable populations.
One Last Shot of Winter
850 mb temperature anomaly projections show widespread values 10 to 20 degrees Celsius below normal across the Midwest and South. That translates to surface temperatures well below seasonal averages.
While calendar spring is approaching, this pattern signals one more meaningful surge of winter-like air for much of the eastern half of the country.
Impacts to Watch
Residents across the central and eastern U.S. should prepare for:
- Frost and freeze concerns across the Deep South
- Increased heating demand
- Potential agricultural impacts where early budding has begun
- Wind chills making it feel even colder
The most intense cold anomalies appear centered from the Upper Midwest down through the Mississippi Valley and into parts of the Southeast.
Contrast Across the Country
While the eastern half of the United States turns sharply colder, the western U.S. is expected to remain above normal, with warmer-than-average conditions across:
- California
- Nevada
- Arizona
- Utah
This sharp temperature contrast highlights the strength of the jet stream pattern driving the Arctic air southward.
Bottom Line
Texas, Louisiana, Mississippi, Alabama, Georgia and much of the Midwest and Great Lakes region are preparing for a significant Arctic blast that could drop temperatures by 30 to 40 degrees in a single day.
Freezing temperatures may reach the Gulf Coast, delivering one final blast of winter before spring attempts to settle in.
