With cold temperatures in place and Pacific moisture streaming in from the southwest, we have the chance to see freezing rain develop across East Texas on Tuesday.
As a result of this threat, a Winter Weather Advisory will go into effect from 3am Tuesday through Noon Tuesday for the counties of Angelina, Cherokee, Nacogdoches, Rusk, Sabine, San Augustine, and Shelby counties. This advisory does not include our southern and western counties, as surface temperatures are expected to remain well above freezing.
The cold air we are experiencing here at the surface is very shallow in nature. That means that temperatures aloft are warm and above freezing. This means there will be no sleet or snow threat, but rather, freezing rain on Tuesday.
Freezing rain is the type of wintry weather that causes ice problems. Due to the warmer temperatures aloft, rain will fall and hit the ground like a cold rain. If our surface temperatures are around freezing (32-35°), then this rain could freeze on contact, causing some icing issues.
At this point, we do feel that temperatures should stay above that 32° mark, limiting the impacts across the area. Main threats will be for our elevated surfaces, such as bridges and overpasses. Tree limbs and power lines should be in decent shape as accumulations should be rather light.
The areas most at risk for ice accumulations of 0.05" or more will be from areas along a Palestine to Rusk to Center line and points north of there. That's because temperatures further north will be a tad colder at the ground.
Snow on Thursday Morning?
We will see another chance of rain on Wednesday, but at this time, we feel it will just be a cold rain and nothing more. However, as the main low pressure system moves overhead Wednesday night and Thursday morning, we could see a change over to snow in a few spots. Right now, accumulations look to be less than an inch, but for you snow lovers out there, there is at least the chance of some white flakes during that time frame.
