Polar Blast in October: Normal or Not?

Heat and humidity continue to rule the month, with most of October coming in above normal. In fact, only four days have been below or near normal in Austin and San Antonio, and only eight days in Dallas.

What You Need To Know

  • Polar air is heading into Texas next week
  • It’s the coldest air of the season so far
  • Near freezing temperatures for some

The good news is that we are only days away from a chilly blast to take over the Lone Star State. Temperatures will plummet about 25-30 degrees from Sunday to Tuesday, and this is all thanks to a strong cold front moving south all the way from Canada.

This storm system will be responsible for producing widespread snow in the Northern Rockies and Northern Plains as well as some light snow in parts of the Texas Panhandle.

It will also usher in the coldest temperatures we’ve had so far this season with some locations dipping into the 30s. Now, you might be thinking that this is a little early for Texas to see winter-like temperatures, but this is not the earliest we’ve recorded freezing temperatures.

Earliest freezes: 

Dallas – October 22, 1898
Waco – October 24, 1917
Austin-Airport – October 25, 2005
Austin-Mabry – October 26, 1924
Laredo – October 28, 1908
San Antonio – October 30, 1917
Corpus Christi – October 31, 1908

On average, we typically see our first freeze in mid-to-late November (around Thanksgiving) in Dallas, Waco, Austin and San Antonio. But across the rest of South Texas, we usually don’t reach freezing until mid-to-late December.
