8:15 PM Update:

Cass county has received between one-half to 1.5" of snow this evening. If you have to travel toward the Texarkana area, travel conditions are becoming treacherous very quickly.

Precipitation is coming to an end this evening. Watch for some bridges and overpasses could become slick especially in the northern portions of East Texas where there was a snow/sleet mixture.


A very cold rain currently in Tyler with a temperature of 32°. We could also be seeing areas of freezing rain as well.

Radar showing snow mainly confined to parts north of I-20. We will continue to see areas of sleet, snow, and rain. Looks like clearing is taking place to our West.

The Winter Weather Advisory has expired for some of our western counties. The rest of East Texas under a Winter Weather Advisory until Midnight tonight.

Here is a look at the temperatures as of 6 PM and the visibilities. Be careful on those roadways tonight.


***A Winter Weather Advisory Is In Effect This Evening***

Wet Snow in central and northern areas and a mixture of snow, sleet and rain in southern areas. After around 5 PM the snow can begin to accumulate on some grassy surfaces and elevated surfaces as temperatures drop to near 32. No major accumulations are expected. However, in some of the northern portions of East Texas where the snow will last well into the evening there could be an accumulation of up to 1 inch on grassy surfaces. This would mainly be near and to the north of Interstate 20 (mainly in Wood, Upshur, Harrison, Marion, Cass, Camp, Morris, Titus, Franklin, Hopkins, Rains and northern Van Zandt counties. Farther to the south, including the Tyler-Longview area, accumulations should be around or less than one half inch, however some bridges and overpasses could become slick after dark.

--Chief Meteorologist Scott Chesner

1:15PM Update:

Areas of sleet across East Texas. Expect a wintry mix to continue to fall through the afternoon and part of this evening. Temperatures are above freezing at the moment and will fall below freezing during the afternoon and evening and making the roads slick. Keep you updated.


Good Friday!

Here's the latest thought of the forecast from the KETK weather team.

This Morning

We remain dry across our area. Cloudy skies stay with us. Temperatures should reach just above freezing in most areas. When the precipitation arrives, temperatures will begin to drop.

This Afternoon
Already this morning on radar we have been seeing some returns in the Brazos Valley area. As of 9:30AM, these returns have been evaporating before reaching the ground.

As the afternoon progresses, we will see the upper level forcing increase across East Texas. This upward forcing will help saturate the air across our area and will produce precipitation in our area. The forcing is caused by an upper level area of low pressure. This low will track to the south of East Texas, but it will send wrap-around moisture into our area, providing the wintry precipitation by this afternoon and evening.

In previous posts, I've been saying that the GFS and NAM were having difficulty with the moisture for this event. These models are mainly large-scale models. This means it can be very difficult to pick up on local and regional aspects of an event—like the one we are dealing with now.

The model below is called the High Resolution Rapid Refresh model (HRRR). This is provided by NOAA and is a mesoscale model--meaning it takes into account the local and regional features that the GFS and the NAM sometimes cannot handle. Because of the forcing, this model shows precipitation increasing over our area this afternoon and evening.

As this precipitation arrives, temperatures will fall below freezing and could create some slick roads tonight. All activity looks to be out of the area between 9-11PM tonight.

I will update this blog as necessary throughout the day.
