(KETK) - Tyler, Tx — The latest model data still suggests wintry weather possible across our East Texas.
Let’s talk about the latest potential.
As of 9:15 PM, a Winter Weather Advisory has been issued for a good portion of East Texas for the threat of freezing rain with ice accumulations near one-tenth of an inch. This is in effect from 9PM Monday night to 6AM Wednesday morning.
There is also a Freezing Rain Advisory for our western counties for the chance of freezing drizzle with accumulations from a trace to a few hundredths of an inch. This is in effect from 12AM Tuesday morning to 6PM Tuesday evening. For Houston and Trinity counties, this is in effect from 3AM Tuesday morning to 12AM Wednesday morning.
All East Texas counties are under an advisory. Click here to see the latest advisory map.
We will continue to have light showers move through the area this evening into tonight. Temperatures will slowly begin to make their way down toward freezing after between 12AM and 3AM.
TONIGHT — TUESDAY MORNING
When I posted yesterday’s blog, the models were hinting a bit more available moisture. The Monday morning model runs have the majority of the moisture to our east. However, the best timeframe for freezing rain in East Texas will be beginning at about 3-4AM. Below are the GFS & NAM precipitation output for 12AM, 3AM, and 6AM.
The model below is a higher resolution and mesoscale model called the RPM. This model shows some freezing rain possible in our eastern counties.
This wintry precipitation turns to rain and sleet during the day on Tuesday with temperatures just above freezing at the surface and below freezing temperatures at 5,000 feet.
Tuesday evening, the trough will swing through East Texas. Temperatures will quickly fall Tuesday evening as this short wave moves through. With moisture in place already on Tuesday and this lifting mechanism taking place, there could be a brief period of another wintry mix.
The biggest concern at the moment is how cold surface temperatures are with this event. A few degrees either way will make a big difference in the forecast.
The next 24-36 hours will be watched very closely. We will keep you updated with the latest weather information online, on-air, and on your mobile device.
