Texas, Oklahoma, Kansas, New Mexico, and Arkansas to See Dangerous Arctic Blast With 40-Degree Temperature Crash Sunday

TEXAS — A powerful Arctic Blast is forecast to sweep across the Southern Plains late Sunday, triggering a dramatic and dangerous temperature drop of 40 degrees or more as warm 70s and 80s rapidly fall into the 30s and 20s in just hours. Meteorologists warn that the incoming cold surge will be one of the most aggressive temperature swings so far this season, bringing sudden winter conditions to areas that have been unusually warm.

Up to 40–50° Temperature Crash Expected

Weather models show a sharp cold front diving south from the Central U.S., pushing Arctic air deep into:

• Texas
• Oklahoma
• Kansas
• New Mexico
• Arkansas

Before the front arrives, many locations will still be basking in upper 70s and low 80s, but readings will plunge to the 30s and 20s Sunday evening, with some northern regions dropping into the teens. This will create a 40° or greater temperature swing, clearly visible on temperature maps highlighting the rapid southward push of Arctic air.

Why This Arctic Blast Is Significant

Forecasters emphasize several key impacts:

• Speed of the temperature drop — dangerous for travelers and outdoor events
• Potential for icy spots if any rain precedes the cold surge
• Risk to livestock, pets, and vulnerable individuals
• Heating demand spike, which could stress local utilities

Sudden temperature swings like this can also trigger strong winds along the front, adding to wind chill concerns Sunday night into Monday morning.

Areas Facing the Coldest Air

Based on the latest model data, expected temperatures by late Sunday evening include:

• Texas Panhandle: Teens to low 20s
• Oklahoma: Mid-teens to 20s
• Kansas: Single digits to low teens
• Northern New Mexico: Teens and 20s
• Arkansas: Upper 20s to low 30s

The cold air will continue expanding southeast through early Monday.

Residents Urged to Prepare Ahead of Sunday

Meteorologists advise residents to:

• Bring pets and animals indoors
• Protect pipes and outdoor water lines
• Prepare extra blankets, heaters, and emergency supplies
• Check on elderly neighbors
• Avoid unnecessary travel during the front’s arrival

The sudden shift from warm to frigid conditions can catch people off guard, especially those planning outdoor activities Sunday afternoon. NapervilleLocal.com will continue monitoring this Arctic outbreak with updated forecasts as the front approaches.
