Houston’s early 2023 humidity will break today with the passage of a front

Good morning. A cold front is moving into Houston this morning, which will knock down the very sticky humidity the region has experienced for the last several days. Some storms will persist south of Interstate 10 this morning, but by mid- to late-morning drier air will be replacing this moisture, and bringing an end to rain chances. We’ll then be rain-free until the weekend, when the forecast turns more complex as another front slogs into the area.

Tuesday

Skies will clear out later this morning, and we’ll see a pleasant, sunny day with temperatures around 70 degrees. Winds will be out of the north or northwest at 10 mph, with slightly higher gusts, so this won’t be a howling front in that sense. Lows tonight will drop down to around 50 degrees in Houston, with colder conditions in outlying areas.

Wednesday and Thursday

These will be fine January days, with highs in the upper 60s to 70 degrees, and lows in the upper 40s. Days will be sunny, and nights clear. Winds, generally, will be light.

Friday

As high pressure moves away from the area, the onshore flow will resume. Nevertheless, for most of Friday we should see sunny skies, with highs in the low 70s. Clouds will start to build Friday night, with lows dropping only to around 60 degrees, or slightly below that, in Houston.

Saturday and Sunday

The forecast for the weekend is starting to come into better focus. What we’re likely to see is a slow-moving front push into the Houston and generate widespread rain showers. At this point I think skies will be mostly cloudy on Saturday, with perhaps a 30 percent chance of rain. The better chances will come into the forecast on Saturday night and Sunday. High temperatures on both days will likely be in the 60s, with lows in the 50s. I don’t think these will be flooding rains, but more likely showers and a few thunderstorms of the light- to moderate variety. Most areas should see on the order of 0.75 to 1.5 inch of rain, give or take, spread out over one to two days.

Next week

As the aforementioned front continues to linger over or near Houston, rain chances will likely persist into Monday morning before we finally clear out some behind the front. Most of next week looks pleasant for January, with highs in the 60s or low 70s, with lows in the 40s and 50s.

Storms are possible late tonight ahead of a decently strong front

Happy New Year! The year 2023 has started out warm, but a front will arrive on Tuesday morning to bring more seasonal conditions back into the forecast. Ahead of the front, we have some concerns about the potential for thunderstorms and severe weather later today and tonight, but overall the dynamics are not too supportive for this.

Monday

With very warm conditions this morning, and lows only in the low 70s, we are seeing some sea fog developing again. This should burn off by mid-morning, leaving us with a cloudy day and highs in the upper 70s. Two things we’ll be watching for today: strong southerly winds and the potential for thunderstorms. The winds are pretty much a certainty, as the onshore flow responds to high pressure over the central United States. We’re going to see gusts up to 30 or 35 mph this afternoon. As for the storms, I’m guessing a capping inversion in the atmosphere will limit activity, but you should be aware that there is the potential for some storms to break through the cap later this morning and early afternoon. The potential for rain lingers tonight as lows drop into the upper 60s.

Tuesday

Our second chance for storms will come late tonight and Tuesday morning ahead of the actual cold front. A (broken?) line of showers and thunderstorms should push into areas northwest of Houston around 3 to 5 am, the metro area around 5 to 7 am, and off the coast by around 10 am. For some people, this will be the first day commuting back to the office for awhile, so be aware you may need some extra time due to the potential for storms if this timing is accurate. The skies will clear pretty quickly after the storms, so we can expect clear skies and highs in the low 70s on Tuesday afternoon with notably drier air. Lows drop to around 50 degrees on Tuesday night, with colder conditions further inland.

Wednesday, Thursday, and Friday

Our weather settles down for the rest of the week, with mostly sunny skies and highs in the mid-60s to 70 degrees. Lows will generally be in the mid-40s through Thursday night before a warm-up heading into the weekend.

Saturday and Sunday

The high pressure system that will bring sunny weather during the second half of the work week will slide eastward by Friday, setting up a warmer and potentially wetter weekend. At this point I think Saturday will be mostly rain-free, with partly sunny skies and highs in the mid-70s. Sunday has a better chance of rain, perhaps 30 percent, and at this point I’d guess we’ll see mostly cloudy skies and highs of around 70 degrees.

Conditions will cool down to more seasonable temperatures by mid-week. (Weather Bell)

Next week

I’m afraid there is not a whole lot of certainty in the forecast by around Sunday and beyond. I think the most likely scenario is that a cold front moves into Houston and essentially stalls, setting up a pattern of a few colder, and rainy days. But do I feel highly confident about such a scenario? I do not.

Looking ahead to the weekend of January 14 to 15, a few people have asked me about conditions for the Houston Marathon. At this point there is a decent signal in the global models for a slightly stronger front toward the end of next week, so I’m thinking we’ll see start line temperatures in the 40s. The good news is that right now it does not look too warm or too muggy. The bad news is that a forecast for 13 days from now is about as helpful as cramps at mile 20.

Houston will kick off 2023 on a very, very warm note

It was 15 degrees in Houston a week ago this morning. We managed 77 degrees yesterday afternoon. The winter roller coaster is here. In addition to the warmth, we saw some pretty gnarly storms over parts of the area, even a Tornado Warning down near Galveston.

Rain totals were highest southeast of Houston, especially in Galveston and Chambers County, which saw 3 to 6 inches of rain. (NOAA NSSL)

As Eric accurately noted yesterday, the rainfall was quite erratic. Rain totals ranged from over 5 inches near in Galveston County to next to nothing in western Harris, northern Fort Bend, and southern Waller Counties. In between, it was hit and miss. Some areas saw tremendous displays of lightning, while others may have only heard some distant rumblings. So it goes. We’ll settle in to some very mild but fair weather over the next few days before our next speed bump on Monday.

Today

We have a little patchy fog in spots this morning. Other than that, just a lot of clouds. On the whole, we’ll call it “decreasing clouds” with hopefully a bit of sunshine later today. Depending on sunshine, we’ll either hit the upper-60s or low-70s today. Accompanying last evening’s system was a very weak front that will make its presence felt tonight, sort of. Light north winds should allow temperatures to dip into the 50s.

Morning lows on Saturday look seasonable across the area, with most spots in the 50s for the last morning of 2022. (Pivotal Weather)

New Year’s Eve & air quality concerns

We should have partly to mostly sunny skies across the area tomorrow, along with highs into the 70s. All your festivities, from “Noon Years” for those of us with little ones to watch parties for TCU hopefully beating up on the Fighting Harbaughs of Michigan to evening celebrations look great. The only thing to watch will be areas of fog near the coast, so use some caution if you’ll be out and about late Saturday night and after midnight Sunday morning.

One word of caution: Fireworks and air quality.

This forecast sounding (vertical wind, temperature, and humidity profile) for midnight on New Year’s is exactly what we do not want to see with fireworks likely being shot off in droves. Unhealthy or even hazardous air quality is possible early Sunday morning. (Pivotal Weather)

Unfortunately, the setup this New Years is going to be one that features mostly light winds and likely a very strong inversion in the atmosphere. In simple language? All the pollution from those fireworks everyone sets off on New Year’s Eve probably isn’t going to go far, and we are likely in for some very unhealthy, if not outright hazardous air quality across the region at times late Saturday night and early Sunday morning. The good news is that winds don’t look totally calm, but they will be light. So if you have respiratory difficulties, it would be a good idea to keep an eye on area air quality readings. Winds and “mixing” will pick up after 9 or 10 AM Sunday. So if we end up with a lot of trapped smoke in the early morning, the afternoon should at least be nicer.

New Year’s Day

As noted, air quality may be an issue Sunday morning, but at least it should become sunny. Some morning fog is possible, if not likely in spots, and clouds will likely increase through the day. Highs could get to 80 degrees in spots. Coastal areas may again see fog persist deep into the day.

Monday

The forecast for Monday continues to look a bit tricky. It may play out very similar to yesterday, with numerous storms, locally heavy rain, and isolated severe weather. Or it could be more widespread. We still don’t have a great handle on this and likely will not until Sunday. Look for an average of a half-inch or so of rain, but it’s likely many places see less and others, especially east of I-45 see 3 inches or more. Highs will top off near 80 in spots, 70s elsewhere.

Rest of next week (and chances of a freeze-peat this winter?)

After Monday’s rain, a cold front and slow clearing should arrive on Tuesday, bringing much cooler weather for Wednesday. We’ll probably drop back to 60s by day and 40s by night for much of the rest of next week. Another warm up is likely late next week or weekend.

We’ve seen a lot of questions about the chances of another freeze this winter. Put simply: We have no idea. There’s no rule that says if you freeze in December like we did this year that it can’t happen again later in January or February. The odds are no different the rest of winter today than they were a month ago. So, yes, it’s possible it could happen again. Likely? Not necessarily. There’s no sign of emergent cold in Canada or the Plains over the next 2 weeks, meaning any strong cold is unlikely here through mid-January. If anything, the jet stream in the Pacific Ocean is trying to ramp up again in mid-January, which could signal another period of warm weather to come. The takeaway? While we see no sign of a freeze-peat right now, that doesn’t mean things can’t change later in January or February. But it’s neither more or less likely than normal because we had one this month.

Happy New Year to you, readers. On behalf of Eric, Maria, Lee, and Dwight, thank you all for a great 2022, and we look forward to another great year in 2023.

Much warmer this morning, with storms possible tonight ahead of a mild New Year’s holiday

Good morning! It is remarkably warmer this morning across Texas and Louisiana, in some cases more than 30 degrees above lows from just 24 hours earlier. Aside from this dramatic warm-up, the big story for the next couple of days is our rain chances later today and tonight, and then mild conditions for the New Year’s holiday.

Thursday

Starting with lows around 60 degrees, we’ll warm up into the upper 70s today with mostly cloudy skies. With ample moisture in the atmosphere and an inbound disturbance, there will be a chance of showers and thunderstorms today, perhaps around 50 percent. But the greater chance of storms will come late this afternoon, evening, and during the overnight hours. These storms will be hit or miss, I think, with some areas picking up just 0.25 and inch of rain, but nearby areas seeing 2 or even 3 inches. Areas that see the heaviest rainfall may experience minor street flooding.

Friday

Rain chances likely end during the pre-dawn hours. A weak front will the slide into the region on Friday, so we likely will see partially clearing skies during the afternoon with highs in the low-70s. Winds will be light, shifting to come from the north. Lows on Friday night will drop into the low 50s.

New Year’s Eve

The final day of 2022 will be a fine one, with mostly sunny skies, moderately dry air, and highs in the mid-70s. Temperatures at midnight will be mild, about 60 degrees, with perhaps a few clouds in the air. Celebrate the new year outside, and safely!

New Year’s Day

The first day of 2023 will be a bit warmer, with highs in the upper 70s to 80 degrees, and partly sunny skies. Lows on Sunday night will only drop into the upper 60s, and perhaps only briefly.

Monday

This will be a wet, and potentially stormy day ahead of another cold front. Details are to be determined, but we’re likely to see 1 to 2 inches of widespread rainfall. The question is whether all of the dynamics in the atmosphere line up to favor severe storms, and for now I think the answer is that such conditions are more likely to the northeast of Houston, rather than over the city itself. We shall see. Otherwise expect highs in the upper 70s.

Rest of next week

Most of next week will probably see highs in the 60s, with lows in the 40s and 50s. There looks to be a fair amount of sunshine as well. So overall, the first week of 2023 looks to be fairly nice. Hopefully one might be able to say that about the whole year.

Holiday lights

We’re in the final days of being able to enjoy the holiday light shows at Space Center Houston and the Houston Botanic Garden. Here’s a review we wrote of these attractions earlier this year. You can find more information about each there, along with a discount code to save you $5 on each ticket.
