Warmer and wetter as Houston looks to close out 2022

Good morning. After about 10 days of much colder weather, Houston will soon return to warmer conditions to end the year 2022. Today, in fact, will be the last chilly day of the year, after which highs in the 70s will persist into early 2023. We also will have two periods of rainfall during the coming week, but I think we’ll manage to squeeze out some fair conditions for the New Year’s holiday in between.

Tuesday

Lows have fallen to freezing, or near freezing, along and north of Interstate 10 this morning, but areas closer to the coast are generally in the upper 30s to around 40 degrees. Skies will be sunny today, with highs in the mid-50s. The most important change will come later today, as high pressure slides eastward, and our winds take a more southerly turn. This will mark a definitive end to the Great Christmas Cooldown of 2022. Lows tonight will drop into the low 40s in Houston.

Wednesday

Skies will be mostly sunny on Wednesday, with highs in the low 70s. Winds will be notable, out of the south at 10 to 15 mph, with gusts up to 25 mph. By Wednesday night we’ll see low temperatures falling just into the 60s, with a slight possibility of some fog.

Thursday and Friday

The end of this week looks wet, as increasing moisture levels from the southerly flow combine with an atmospheric disturbance to produce a healthy chance of rain. These should be mostly cloudy days, with highs in the low 70s. Rain chances look best on Thursday and Thursday night, but a chance will persist through the day on Friday. Overall accumulations look greater for the eastern half of Houston, but I expect much of the region to see at least 1 inch of rain, with some areas seeing 2 or more inches.

Saturday and Sunday

Fortunately, it looks like a weak front will clear things out for the holiday weekend. Right now I’m penciling in highs in the low to-mid-70s on New Year’s Eve, with partly to mostly sunny skies, and lows dropping into the upper 50s to 60 degrees by around midnight. Rain chances are pretty low, which is good news for revelers. Skies on New Year’s Day will likely be partly sunny, with highs in the mid-70s. All in all, the turn into 2023 looks fairly mild.

Next week

The weak front won’t last long, and at some point I expect clouds to return on New Year’s Day. This return of moisture will set the stage for another wet period—most likely on Monday January 2, but some uncertainty remains. This could easily bring another 1 to 3 inches of rain to the region before a front brings some moderately cooler and drier air into the region.

A slow—emphasis on slow—warming trend begins today, lasting through the holiday period

Good morning. Much of Houston has once again sunk into the upper teens this morning, as a hard freeze grips the region. However, this will be the worst of it, with Houston seeing one more night in the 20s heading into Christmas morning. Next week looks considerably warmer.

Christmas Eve

Skies will be mostly sunny today, and if you live south of Interstate 10, highs may eventually climb to 40 degrees or higher. Further inland you’ll probably remain in the upper 30s. A noticeable, and welcome, change today will be much reduced winds out of the north at 5 to 10 mph. Clear skies tonight will allow temperatures to drop into the mid-20s in the city of Houston, with colder conditions further inland. In terms of electricity, the state power grid seems to be holding steady. We expect that to continue.

Christmas Day

Don’t tell my niece, but she’s getting a trampoline for Christmas. While it will still be cold on Sunday, with highs in the mid-40s it will certainly feel warmer than recent days. So if you dress warmly, with the sunshine and just a light wind, conditions should be fine for outdoor activities such as trampoline jumping after the early morning chill burns away. Overnight lows on Sunday night will get down to about freezing in Houston, with colder conditions inland, and more moderate ones along the coast.

Monday and Tuesday

A bit of uncertainty remains about whether a reinforcing front pushes into Houston on Monday night, or washes out, but I don’t think it matters in terms of precipitation. Both of these should be mostly sunny days, probably with highs slotting into the 50s. Monday nights lows may drop into the 30s, but Tuesday night will be warmer.

Wednesday

This has the look of a pleasant, partly sunny day with highs in the 70s.

Thursday and Friday

The pattern turns more unsettled by the end of the week as high pressure shifts eastward, and we’re opened up to a warmer, more humid flow from the Gulf of Mexico. This will bring a notable increase in rain chances. Accordingly I expect both of these days to be mostly cloudy, with at least a 50 percent chance of rain, and highs in the 70s.

New Year’s Eve and New Year’s Day

The forecast is fairly muddled by this point, but my general expectation is that some kind of weak front is going to push into the region on New Year’s Eve, or thereabouts. This probably will bring an end to the rain showers before festivities start later on New Year’s Eve, but at this point out it’s too far away to say that with any confidence whatsoever. The front may sap some of the humidity, as well. My bet for highs on New Year’s Day would be about 70 degrees, but again, it’s a long ways off.

Best wishes for a Merry Christmas and Happy Holiday season

This will be our last post until Tuesday, December 27. It has been a long week due to the cold weather, and with relatively calm conditions ahead we’re going to take a couple of days off to celebrate the holiday weekend. So for Matt, Maria, Lee, Dwight, Hussain and everyone else who contributes here at Space City Weather, let me wish you joy on Christmas Day and during the rest of this holiday season. Your trust is the greatest gift we can receive.

As the region faces another cold night, energy companies ask Texans to conserve power right now

Hi everyone. Just a quick update this evening to set the table for a very cold night, and to provide what limited information we can on the state’s power situation. The bottom line is that lows tonight will drop to around 20 degrees in the city of Houston, with colder weather in outlying areas, and as temperatures plummet we are likely to see a strain on the state’s power grid. Please conserve energy during the next few hours.

Friday night

With lighter winds tonight, lows probably will be 2 to 5 degrees above the extremely cold conditions observed on Friday morning. However, with winds gusting up to 15 mph the apparent temperatures will be in the single digits again. This is weather unfit for people or pets, so please take precautions, as well as keeping in effect your cold-weather plans for pipes. We’ll warm up a little bit more on Saturday morning, with area highs reaching about 40 degrees. There will be less wind, as well, which certainly will be a welcome change.

Energy conservation

Matt and I have been watching the ERCOT supply and demand tracker all day, and it seems that the agency’s estimates for power demand have been consistently low. Understanding the ins and outs of this predictive tool are beyond the scope of a meteorology site, but the Texas Tribune has a helpful story on the issue. The bottom line is that, as of 7 pm CT, ERCOT predicts that it will have enough energy capacity to meet demands tonight. But things are going to be cut really close from now until 10 pm or so.

To that end, some energy companies have been asking residents and businesses to conserve energy usage tonight. In an email to its electricity customers, Reliant asked for conservation through at least 10 pm CT by taking the following steps: 1) If you have an electric heater, set your thermostat 1 to 2 degrees lower and run ceiling fans clockwise; 2) Roll up towels or blankets and put them under drafty doors and window sills in your home; 3) Hold off on running your dishwasher, washer and dryer.

CenterPoint, which provides natural gas in the Houston region, is also calling for conservation. In particular, the company asked for people to turn off pool heaters: “We encourage customers to be especially mindful of their pool heater usage. One pool heater uses as much natural gas as 4 residential homes. Customers can keep their pumps on without the heater to prevent their pool water from freezing.”

To be clear: We do not anticipate widespread, extended blackouts tonight or tomorrow like the state experienced in 2021. Warming on Saturday should really help things out. However there may be issues this evening, and any steps you can take would help.

I’ll be back with a final forecast post on Saturday morning ahead of the Christmas holiday. Be well tonight, friends.

Arctic air now moving into the Houston area, expect very low temperatures tonight

The long-advertised front has arrived, bringing a sharp dose if frigid air diving down from the Arctic Circle. Wind gusts this afternoon have exceeded 40 mph at multiple locations this afternoon, including a top speed of 48 mph at Hobby Airport. As of 5:30 pm CT, air temperatures remain just above freezing in the Houston metro area, but that will not last long as the mercury starts to drop tonight.

Cooldown

Houston is headed into the icebox for a solid 36 hours. Lows tonight will likely fall into the mid- to upper-teens for all the metro area, aside from the immediate coast, which may hold at 20 degrees or slightly above. Even will full sunshine on Friday, high temperatures may only briefly reach 32 degrees during the afternoon, whereas areas further inland may only top out at about 30 degrees. Conditions will be very cold again on Friday night, with lows perhaps only 2 to 5 degrees warmer than Thursday night. By Saturday, finally, the area should see highs of around 40 degrees.

The good news is that there is no snow or ice on roadways, so aside from blustery conditions it is safe to drive throughout the greater Houston area and beyond. Roads will remain dry through Christmas Day and beyond.

Power

One of the major problems during the February 2021 freeze was the lack of power, when “rolling” blackouts became permanent due to poor management of the Texas electricity grid and a lack of oversight for proper winterization of power plants. It does appear this problem has been solved. ERCOT is reporting excess power generating capacity, and expects to have electricity to meet demands overnight as temperatures plummet across the state. You can track supply and demand in real time here.

Next post

Matt will have a comprehensive update for you by around 6:30 am CT on Friday. Until such time, please stay warm, make sure your pets and neighbors have the shelter they need, and take care of one another. It is the holiday season, after all!
