Treacherous travel north and west of Houston, but precipitation is winding down

First off, travel is becoming very treacherous in parts of western Harris, northern Fort Bend, Austin, and Waller Counties. According to the Drive Texas map at 8:30 PM, there are icy patches in many spots west of Houston. A 10-vehicle crash was just reported on the Westpark Tollway in Clodine.

If you can avoid travel tonight, it’s best to do so, especially west of Houston. If you cannot, please use extreme caution, especially on bridges and overpasses. Based on reports to our west, once temperatures hit 29 to 30 degrees, that’s generally when ice issues seem to begin. Most of the close-in Houston area is 30 to 32 right now, but it drops to 29 and 30 north and west of there. I would expect to see some major freeway flyovers on the west side of the city close soon, if they have not already. South and east of Houston, temperatures are still 33 to 34 degrees, so icing isn’t a concern for now.

As far as the good news goes, it would appear that a lot of the precipitation is exiting the area or weakening. Radar as of 8:35 PM shows the heaviest, steadiest precipitation either along the coast or exiting to our east. This should continue to wane over the next few hours.

That said, we will likely see pockets of light freezing rain or freezing drizzle continue a little longer this evening before shutting down overnight. And with temperatures not warming up until late morning or early afternoon tomorrow, what’s frozen out there will likely stay in place until at least that time. Coastal areas may see a little light freezing rain or drizzle overnight, but it would likely only amount to a few isolated slick spots. Still, exercise caution there as well tomorrow morning and be aware of isolated patches of black ice over the entire area.

Nighttime temperatures won’t stray a ton from where they are right now, so look for lows in the mid to upper 20s north and west and near freezing south and east.

By no means will this be a memorable freeze for the Houston area, but you should still make sure any sensitive plants are protected the next few nights and have any exterior pipes wrapped and irrigation systems off.

The most important news of all? ERCOT’s situation is healthy right now, and there are no conservation notices posted. All available evidence and data implies that we should be able to manage fine through tomorrow morning.

We may see some sunshine tomorrow afternoon, but temperatures will likely struggle into the upper 30s. A slow warmup is expected this weekend. I’ll have more on that for you in the morning. For now, stay safe and stay warm!
