Year: 2024

We start this morning with a quick celestial note: Earth reached perihelion at 6:38 pm CT on Tuesday night, meaning it reached the closest point to the Sun in its (slightly) elliptical orbit about our star. Ironically for northern hemisphere residents, though we are closer to the Sun during the winter by a few million miles, it is coldest time of the year. This is due, of course, to the tilt of the planet’s axis rather than proximity to the Sun. We’ll reach our furthest point from the Sun, aphelion, just after midnight on July 5 of this year.

Speaking of weather, rain showers on Tuesday evening and this morning overperformed a little, dropping 1 to 2 inches across most areas south of Interstate 10, with lesser amounts inland. We’ll now see a couple of drier days before rain showers return on Thursday night and Friday. All of this is working toward a gorgeous, winter-like weekend.

Wednesday

Skies will be mostly cloudy today, with highs pushing perhaps into the mid-50s. After some gusty conditions overnight as a coastal low pressure system passed by, winds will be lighter today, generally from the north, at 5 to 10 mph. Lows tonight will be fairly chilly, dropping into the low 40s in Houston, with cooler conditions further inland.

Thursday

This will be a mostly sunny day, probably, with highs in the upper 50s. Winds will be light, generally from the northeast. Another coastal low will be building offshore, but I think its associated rain showers will remain away from the Houston area during the daytime and evening hours. Lows on Thursday night will drop to around 50 degrees, with some light rain possible after midnight.

Friday

This looks to be a wet day, with most of the area picking up between 0.5 and 2.0 inches of rain between early Friday morning and the evening hours. Rain accumulations should be greatest closer to the coast, and the low pressure system. I think the worst of the weather, including stronger thunderstorms, will remain offshore. So I expect this to be a mostly mellow rain event, but it will definitely put a damper on any outdoor plans you have. Look for highs in the upper 50s, and lows Friday night dropping into the low to mid-40s.

Saturday and Sunday

The weekend looks fine and mostly sunny. Highs on Saturday will be around 60 degrees, with overnight lows in the mid-40s, and then a bit warmer on Sunday, in the low 60s. It should be a great winter weekend for outdoor activities. Enjoy!

Next week

A chance of rain showers returns on Monday before a stronger front moves through. This will set the stage for colder mid-week weather, with the temperature likely bottoming out on Wednesday morning. A light freeze looks possible for inland areas, but we’ll have to see as we get closer. Temperatures then warm up again before another front likely cools us down for next weekend. If you’re weather watching for the Houston marathon on January 14, the forecast still looks chilly and dry, but the details remain fuzzy. Nevertheless I’m cautiously optimistic about running conditions!

Before we get too far into the new year, let’s take a quick look back at 2023. December finished with an average temperature of 57.3 degrees, which was 1.9 degrees above normal for the month. The coldest temperature of the month came on Dec. 11, when the low reached 33 degrees. As I noted last week, Houston did not record a single freeze during the calendar year. It has now been 372 days without a freezing temperature, and counting. We do have a chance at a freeze during the middle of next week, but that remains far from certain.

Last year was the warmest one on record in Houston, where meteorological records go back nearly a century and a half. If we look at the continental United States, we can see that large swathes of Texas, and a few other southern states, had their warmest year on record, or at least one of the five warmest on record. With El Niño persisting at least into the spring of this year, I would expect 2024 to rank very highly in terms of temperatures as well for Texas. But with the weather one can never be sure, and so we’ll be here every step of the way.

Tuesday

Rain is coming, but it should hold off for much of today. Skies should be mostly cloudy, with highs only topping out in the mid-50s for most. Winds will come from the east, at about 10 mph. Starting this afternoon we should see a mass of showers congeal to the west of Houston in conjunction with a low pressure system, and this will move through late this afternoon, evening, and during the overnight hours. Accumulations through Tuesday night should be on the order of 0.25 to 1.0 inch for most. With temperatures dropping into the low- to mid-40s it will be a cold and rainy night, but I don’t anticipate any particularly severe weather.

Wednesday

These rains will most likely end during the pre-dawn hours. After a cloudy start we could see some partial clearing of our skies by Wednesday afternoon, with high temperatures likely peaking only in the mid- to upper-50s. Lows on Wednesday night will probably be the coldest of the week, dropping into the upper 30s for inland areas, and low 40s in the urban core of Houston and closer to the coast.

Thursday

This looks to be a fine, sunny winter day with highs in the upper 50s.

Friday

Round two of rainfall arrives on Friday, with another low pressure system driving increased rain chances. The most likely time for rain will be during the daytime, and we likely will also see some thunderstorms. Will they be severe? Right now the overall dynamics do not favor this so much, so perhaps not. But I’ll be keeping an eye on it. In any case, I’d expect accumulations of 0.5 to 2 inches for most areas, so it could be a bit of messay day on the roadways.

Saturday and Sunday

After Friday’s mess clears out, the weekend looks sunny and cool. We’re talking highs of around 60 degrees on Saturday, lows around 40 degrees on Saturday night, and temperatures a bit warmer on Sunday, perhaps in the low 60s. Enjoy.

Next week

The forecast turns a bit fuzzy next week, but the broad outlines are clear. We’re going to see a brief warm-up on Monday, with temperatures in the low-70s, before some rainfall and a front arrives. This should pretty sharply cool things down for Tuesday, and by Wednesday morning we should be quite cold, perhaps even flirting with a freeze.

If you’re running the Houston marathon, our first peek at weather for Sunday, January 14, is necessarily blurry. But the most likely scenario is that some sort of reinforcing front pushes through ahead of the weekend, leading to a cold Sunday, perhaps starting in the 40s, and rising to the 50s. Certainly I can’t rule out rain showers, but at this point there’s no strong signal for it. I like it cold and dry, so this is an ideal forecast for a slow-goer like me. Such a far-out prediction is, of course, very speculative.
