Monday morning will start off with a cold rain, with freezing rain taking place around Palestine and Tyler.
As we progess through the day, the freezing line will continue advancing southward, leading to freezing rain and sleet taking place across Lufkin and Nacogdoches.
The main impact areas will be for the shading in blue, where significant ice accumulations are expected.
A winter storm is brewing and has its sights set on East Texas on Monday. This has prompted a combination of Winter Storm Warnings, Winter Weather Advisories, and a Freezing Rain Advisory to be posted for most of our counties and communities in Deep East Texas.
Our precipitation in the early morning hours on Monday will initially start off as just a cold rain, with temperatures coming in just above the freezing mark.
However, as we progress through the morning hours, the freezing line will continue to sag further south as temperatures fall down to the 32° mark. Once that happens, we will see a transition from liquid rain to freezing rain mixing in with sleet. This will lead to our weather conditions going downhill very quickly.
Keep in mind that areas along and south of a Trinity to Leggett to Woodville line may not see any wintry precipitation until late in the day. That will be due to the surface temperatures across our southern counties and communities remaining just above the freezing mark for a good majority of the day.
Our first two image attachments show how that freezing line will evolve and push southward throughout the day. The position of that freezing line will be a key factor as to not only our precipitation type, but the amounts of ice and sleet we receive as well. Any deviations in that freezing line will greatly alter which areas get affected by wintry precipitation during the day on Monday.
Based on our latest guidance, we expect the highest impacts from this winter storm to be felt across our northern counties and communities, where a Winter Storm Warning is currently in effect. That means areas generally along and north of an Alto to Mount Enterprise line are most likely to see between a quarter to a half an inch of ice and sleet accumulate throughout the course of the day on Monday. These amounts are sufficient enough to lead to thick patches of ice on roadways, and may lead to some scattered power outages as power lines come down.
The central parts of Deep East Texas, which include the cities of Crockett, Lufkin, Nacogdoches, San Augustine, and Hemphill, can expect about a tenth to a quarter of an inch of ice accumulations by late Monday afternoon. This will lead to some patches of ice and create problems on bridges and overpasses.
And finally, our far southern counties and communities will see a cold rain for most of the day, before seeing a transition to freezing rain by Monday afternoon. Impacts for areas around Trinity, Livingston, Woodville, and Jasper will not be nearly as high as areas to the north. However, you will still want to take precautions traveling on area roadways, especially as you head home from work late in the day.
Sometimes all the advisory terminology can get rather confusing. Just remember that the further north you go, the more likely you will run into more ice and hazardous travel.
