The last time the 'Polar Vortex' moved through East Texas we got the extreme cold, but thankfully no precipitation.  Looks like we're not going to get quite so lucky this time, especially for areas south of Lufkin and Nacogdoches. 

A Winter Storm Warning has been issued for those areas to the south and southwest of the Neches River.  Basically this means Houston, Trinity and Polk counties as well as all counties directly in a line to Houston and Victoria will be included.  Counties such as Tyler, Jasper, and Newton are not included.

The warning goes into effect at 9 tonight and continues through 9 Friday morning.  Precipitation should start turning to either freezing rain, sleet and/or snow overnight. Anywhere from a tenth of an inch to a half inch of ice and snow is possible in the warned area and that would create driving nightmares.

Even though Lufkin and Nacogdoches are not included in the warned area, temperatures overnight are expected to be in the mid-20's and we do have a 20% chance of precipitation, so we need to be wary as well.
