East Texas — While a few rural areas had some frost and a light freeze around Halloween, most of East Texas has not had an official freeze so far this season.

That will change overnight and early Tuesday morning thanks to a cold Canadian high pressure system that has settled in over the area. 

Temperatures will reach lows by daybreak ranging from 24-27 in some rural areas to 30-33 in the downtown areas of Tyler and Longview. That means a widespread frost all across East Texas and a light freeze for many areas. 

The duration of the freezing temperatures will likely be about 8 hours out in the country (from around Midnight until 8 AM) to about 4 hours in the bigger ctiies (from around 4 AM until 8 AM).  So protect all sensitive vegetation. After sunny skies with highs near 60 on Tuesday, look for more frost early Wednesday morning as well.
