Good morning. Over the next seven days Houston will see mostly winter-like weather, with only one or two days with a high temperature of around 70 degrees. If you’re participating in the Houston full or half marathon this Sunday, I’m now highly confident that conditions will be cold, perhaps with start line temperatures in the upper 30s or low 40s.

Monday

Skies have cleared out this morning for inland areas, and will soon for the coast. This will lead to a mostly sunny day, with highs in the upper 50s for most areas. Winds will blow out of the north at about 15 mph, with higher gusts, keeping a chill in the air all day. As winds die down this evening we’ll see ideal conditions for radiational cooling, with lows dropping to about 40 degrees in the city of Houston, with cooler temperatures further inland, and slightly warmer temperatures along the coast.

Tuesday

This will be another cool and sunny day, with highs of around 60 degrees. Winds will be lighter, but shift to come from the northeast and then the east. As a result, temperatures on Tuesday night will still be chilly, but 5 to 10 degrees warmer.

Wednesday

A bit warmer, with highs in the mid-60s, and a few more clouds as high pressure shifts away. Lows will be around 50 degrees in Houston, with colder conditions in outlying areas.

Thursday and Friday

These should be the warmest days of the week, with a southerly and southwesterly flow pushing highs into the upper 60s on Thursday, and low- to mid-70s on Friday. Expect mostly sunny skies. Dewpoints will remain in the 50s, so it’s never really going to be “sticky” outside, however.

Saturday and Sunday

A strong cold front should arrive sometime between Friday evening and mid-day Saturday. Questions yet to be answered are whether any rain will accompany the front (probably not) and how cold the air mass will be (fairly cold, probably). Depending on the front’s timing, high temperatures on Saturday are likely to be around 60 degrees, with gusty northerly winds. Saturday night should be quite chilly, with a colder day on Sunday likely in the 50s. Winds should be lighter on Sunday, helping with the run. Details to come. A warming trend should begin on Monday.

Good morning. The Houston region saw some pretty gnarly weather on Saturday night, with storms producing pockets of 4 to 8 inches of rainfall, prodigious amounts of lightning, and potential tornadoes. (One near Humble is likely to be confirmed later today). Some area bayous, such as Greens and Luce, saw waters rise to the top of their banks, but these floodwaters should now be receding. The good news is that conditions will settle down somewhat today, and then turn cold, calm, and winter-like for the first half of this week.

The focus for rain showers today will turn toward coastal areas, generally south and east of Highway 59/Interstate 69. These areas may see up to 0.5 or 1 inch later this morning and into the afternoon hours before a cold front arrives. The front should reach northwest areas this morning, central Houston during the early afternoon hours, and push off the coast by late afternoon or around sunset. As the front moves through its dry air will scour showers from the region. We should expect no rain tonight.

The first half of the week will see mostly sunny skies, with highs in the 60s and lows generally in the 30s (for inland areas) and 40s. Our next real rain chances will not come until the end of the coming work week.

One year ago, after a warm spell in early January, several readers asked if the 2020-2021 winter was effectively over for the Houston region. Our response at the time was, “It is decidedly not, but we are having quite mild conditions during what is normally the ‘dead’ of winter.” Of course, a little more than one month later, temperatures plunged as part of the Valentine’s deep freeze that prompted widespread, prolonged power outages, deaths, and significant home damage due to burst pipes.

A similar question might be asked this year, especially after record warmth in December, and a high temperature of 77 degrees on Wednesday. However, our answer remains the same. Houston can have pretty strong cold outbreaks through the middle of March, so “winter” will likely last for about two more months. With that said, the window for a terribly cold freeze, on par with what occurred last year, is closing. We probably have about six or seven weeks during which we really need to worry about seeing a really hard freeze. At present there are no indications of such happening.

Thursday

It will certainly feel like winter later today and tonight as a front moves through the region this morning. Drier air will move into the region from the northwest today, and winds will gust up to about 20 mph from the north-northwest. Although high temperatures will get into the 60s this afternoon beneath sunny skies, they’ll drop off pretty quickly this evening, and bottom out at about 40 degrees overnight in Houston. A few outlying areas may see a light freeze.

Friday

Friday will be mostly sunny, and after a chilly start temperatures will warm to about 60 degrees. As winds shift to come from the east and then southeast, our air mass will modify pretty quickly. As a result we should see clouds returning by Friday evening, and temperatures won’t drop much, if at all, during the overnight hours.

Saturday and Sunday

The weekend still looks wet, gray, and warm. The combination of moist air and a low pressure system will yield our first real rain chances since mid-December. The ingredients are there for showers and thunderstorms, and even some heavy rainfall. Right now, models are pegging area-wide accumulations at about 1 inch, but I could certainly see some areas picking up 2 to 3 inches from Saturday morning through Sunday. Rains will likely end by late Sunday morning, so there’s a chance of some sunshine later in the day. Both days look warm, with highs in the mid- to upper-70s. A front will arrive on Sunday afternoon, or evening, to drive the moist air away.

Next week

Accordingly, most of next week should see highs somewhere in the 60s, with overnight lows in the 40s and 50s. Some rain chances return mid-week, and some kind of front should arrive by Friday or Saturday to cool us down for the weekend. Start line temperatures for the Houston marathon still look pretty cold, probably about 40 degrees, give or take.

Up and down, up and down—so will go our temperatures over the next 10 days as Mother Nature vacillates on whether it should feel like winter or spring outside. This is good thing for those who believe variety is the spice of life. We’re also continuing to track the likelihood of rain this weekend, which would be the region’s first meaningful precipitation in about three weeks.

Wednesday

Temperatures are generally starting out in the 50s this morning, and with light winds a few areas of patchy fog have developed. This should not last, and skies will be mostly sunny later today, allowing for temperatures to warm nicely into the mid-70s. Winds will be modest, out of the south and southwest, at 5 to 10 mph. Temperatures tonight will start out moderate, but a cold front will arrive to cool things down. It looks like the front will reach the Interstate 69/Highway 59 corridor around midnight, and push down to the coast between 3 and 6 am. As a result, Houston will be generally in the 40s (inland) to low 50s (near the coast) when you wake up on Thursday. No rain is likely to accompany the front.

Thursday

Conditions will be breezy on Thursday, as northerly air follows the frontal passage. Look for winds gusting up to about 20 mph to go along with sunny skies, and highs likely topping out in the upper 60s. As winds die down overnight, this will set the stage for cold temperatures. I think the urban core of Houston will remain at about 40 degrees, but outlying areas should fall into the 30s. A light freeze is possible for far inland areas, such as College Station.

Friday

This will be a sunny and cool day, with highs around 60 degrees. However as high pressure moves off and winds shift easterly, this will set the stage for warmer weather ahead. Lows Friday night will probably be about 15 degrees warmer than Thursday night.

Saturday and Sunday

Conditions will be quite warm and muggy this weekend, especially for early January. Look for highs in the mid-70s with partly to mostly cloudy skies and plenty of humidity. The onshore flow will also ramp up moisture levels, and this will lead to increased rain chances beginning as early as Saturday morning. This pattern will hold sway until about Sunday afternoon or evening, when the next front arrives. This front may bring additional rainfall with it, and all told I think most areas will average 1 inch or so this weekend, with less for some areas, and more for locations that see some briefly heavy rainfall. Rains will end with the front’s passage, and lows on Sunday night should drop into the upper 40s.

Next week

We’ll see fairly cold conditions next week, with highs in the 50s and 60s, and lows in the 40s and 50s. Another front arrives by the weekend, perhaps Saturday the 14th, to keep things on the cooler side. If you’re running the Houston marathon, my best guess remains chilly start line temperatures of about 40 degrees.
