Good morning. There are some changes in the forecast for our upcoming cold spell, which looks to arrive earlier than anticipated. There is also a slight chance of some wintry precipitation on Sunday night into Monday morning, but the overall odds remain against this for now. The key point is this: There remains a lot of uncertainty about the details of this Arctic outbreak, but they should come into better focus over the next 24 to 36 hours. So please be patient. Matt and I will be here all along the way to tell you what we know, and what we don’t. For now, any preparations you make for the cold should be completed by the end of Saturday.

Thursday

As expected there is fog, some of it dense, across much of the metro region this morning. As it clears we’ll see partly sunny skies and warm temperatures today, with highs pushing into the mid-70s. Southerly winds, gusting at times to 20 or even 25 mph, will be possible. Conditions change tonight as a fast-moving front drops through the area. Expect it to arrive near Katy and The Woodlands a couple of hours after midnight, push into Houston during the wee hours, and move offshore before sunrise. A broken line of showers, and possibly a few thunderstorms, may accompany the front. Overall rain chances are fairly low, however, as I expect a capping inversion to hold sway.

Friday

This will be a cold, blustery day. Skies will be sunny, but winds will be strong out of the north, gusting to 35 mph or so at times. If you’re like me and just finished picking up limbs from winds earlier this week, prepare for round two. Highs will reach the upper 50s, but may stop there. Winds will drop off pretty significantly during the afternoon and evening hours, and this will allow for ideal cooling conditions overnight. I expect lows in most of the Houston metro areas to remain above freezing, but a light freeze is possible for inland areas.

Saturday

After the cold start this will be the last warm-ish day before the Arctic front arrives. We’re looking at partly sunny skies, with high temperatures in the low 60s. Winds will be light. Lows on Saturday night will drop into the low- to mid-40s.

Sunday

Alright, here’s where the uncertainty kicks in. We’re just coming into range of some of the higher-resolution models, which tend to do a better job handling the timing of colder air masses like this. As we see additional model runs today, we should continue to get a better focus on the timing of the front. So I want you to understand that my confidence is low here, and we’re going to need to write the forecast in pencil for a little while.

With that said, the high resolution modeling is indicating that the front could reach Houston by around sunrise on Sunday. Yes, you read that right. If this is the case, temperatures on Sunday morning could be in the 30s for Houston marathon, with northerly winds. (I don’t expect precipitation at this time). This obviously is a significant change from previous forecasts, and something we’ll need to fine-tune. Again, it depends on the timing of the front.

A widespread freeze looks likely for Sunday night, with areas inland of Interstate 10 possibly seeing lows in the mid-20s.

As to the question of freezing precipitation, there are hints of it in the models but nothing concrete. We really need to see more data from the high-resolution outputs before I have any confidence. For now I’d rate the chance of seeing any wintry precipitation, either in the form of sleet or freezing rain, at about 25 percent. I still don’t think it will be significant issue for roadways, but obviously it’s something we’re going to be watching closely.

Monday

This will be a cold day, with highs likely in the mid-30s for most of the metro area. As part of this Arctic front, lows will bottom out on Monday and Tuesday nights. Again, with these temperatures, there is some considerable uncertainty. For areas south of Interstate 10 we are probably looking at lows in the low to mid-20s, whereas areas further inland will be upper teens to low 20s. We will see.

We’ll have another update this afternoon to see where we are with the frontal timing, and lows early next week.

Good morning. As you have probably heard by now, Houston faces the prospect of a hard freeze next week as an Arctic front moves through much of the continental United States. This will be serious cold for the Houston region, and will warrant some preparation. However, this is unlikely to be a disaster on the level of the February 2021 event that sapped the power grid and caused widespread pipe failures. It should be more akin to the February 2022 freeze, which the power grid (and most residences) tolerated much better.

In terms of air temperatures, we are going to see some seriously cold (for Houston) weather next Monday night and Tuesday night. While there is still considerable uncertainty in how far the mercury will drop, lows are likely to drop into the upper teens to mid-20s for much of the Houston metro area. Here are some suggestions for preparing for this event:

Plants: Bring potted plants inside your garage or home. Apply a thick layer of mulch around ground-based plants, and water them. Cover sensitive plants with a sheet.

Pipes: Cover or insulate exposed pipes, including those under raised homes. Turn off and drain water sprinkling systems. Indoors, open sink cabinets to expose pipes to inner warmth.

Pets: Bring pets indoors and ensure adequate warmth for livestock.

People: Check on your family and neighbors to ensure their homes are winterized, or see if they need a warm place to stay.

Wednesday

Winds have already shifted to come from the south this morning, so after a chilly start in the upper 30s we are going to see highs push into the mid- to upper-60s beneath sunny skies. Winds will at times turn a bit gusty. Lows tonight will only drop into the mid-50s. The combination of light winds, warm air, and cool ground will lead to the likely development of fog tonight.

Thursday

That fog will be thickest on Thursday morning, and you’ll probably want to leave some extra time for the morning commute or getting to school. It could linger into the mid-morning hours. Skies will then turn partly sunny, with high temperatures likely reaching the mid-70s. A robust cold front will approach and move through the Houston region on Thursday night. This could result in a broken line of showers and thunderstorms, but at this point accumulations look slight. We can’t entirely rule out some damaging winds or hail with the front, but overall severe storm chances seem fairly low.

Friday

This will be a sunny and chilly day, with high temperatures of about 60 degrees. Winds will be very gusty, perhaps up to 35 or 40 mph during the afternoon hours. Winds should slacken somewhat on Friday night, with clear skies allowing temperatures to drop to near, or just above freezing in the Houston metro area.

Saturday

This should be a pleasant, sunny and winterlike day in Houston. Look for highs of around 60 degrees. Lows on Saturday night will drop into the mid-40s.

Sunday

Skies will be partly to mostly sunny. If you’re running the marathon, after the chilly start in the 40s, we can expect temperatures to reach about 60 degrees by noon, and then a bit warmer during the afternoon. The air will feel reasonably dry. Winds during the run will be out of the south at 10 to 15 mph.

The Arctic front will be arriving later on Sunday in the Houston metro area, likely during the evening hours. There may be a bit of precipitation with the front, but it looks like this will end before temperatures drop below freezing—so at this point I would bet against snow, sleet, or freezing rain. Lows on Sunday night should drop to around freezing in Houston.

Next week

As we start the week, M.L.K. Day is going to be cold. High temperatures may not climb out of the 30s, with a mix of sunshine and clouds. So, brrrr. Temperatures bottom out on Monday and Tuesday nights, with lows likely dropping into the upper teens to lower 20s for much of the Houston metro area. We’re far enough out that some uncertainty remains in how far temperatures will drop (on the lower end, mid-teens are possible, and on the upper end most of the region could stay above 25 degrees). Expect highs to rebound into the 50s on Wednesday, with nights likely staying above freezing after that—but still cold.

Good morning. After the rains, the thunder and lighting, the pea-sized hail and yes, even a tornado north of Houston, we finally come to some calmer weather. Skies will be sunny today, with no rain or storms in sight. But there will be plenty of wind and cold air. If you don’t like that, well, fine. Houston’s weather will be changing significantly on almost a daily basis for the next week at least. Cold today. Balmy by Thursday. Near freezing by Saturday morning. Warming up again on Sunday. Then very likely freezing by early next week with our coldest weather in more than a year.

Buckle up, y’all, because its rollercoaster time in the Bayou City.

Tuesday

It’s a blustery, cold morning outside. Temperatures are generally in the low 40s across the metro area, and when you layer wind gusts of 25 to 30 mph on top of that, it feels like the 30s outside. Strong northerly winds will persist for much of today. Skies will be sunny, but with the colder flow highs will only reach the mid-50s. Skies will be clear tonight, with lows generally in the 30s, though above freezing for the majority of the metro area. Winds will slacken some overnight, finally.

Wednesday

Pretty quickly, the flow will reverse itself, coming from offshore. This will allow temperatures to warm into the mid-60s, with plenty of sunshine. Clouds will start to build on Wednesday night, as lows drop only into the mid-50s.

Thursday

This will be a fairly warm day, with an ongoing southerly flow. Skies will be mostly cloudy, with highs pushing into the mid-70s. The region’s next front will move into the Houston region some time on Thursday night, and there could be a broken line of showers and thunderstorms accompanying it. Right now things don’t look too serious for Houston, but there is a risk of severe weather to the northwest of the metro area, including northern parts of Montgomery County.

Friday

This should be a sunny day, and will have colder temperatures. Look for highs of around 60 degrees. Friday night will be cold, with lows dropping into the 30s. A light freeze is possible for inland areas on Friday night with clear skies and light winds.

Saturday and Sunday

This will be a sunny and cool day, with highs of around 60 degrees. As the onshore flow returns on Saturday we’ll see overnight temperatures moderate on Saturday night. For my fellow marathon runners, there’s still a bit of uncertainty about Sunday morning. But my best guess for start-line conditions is temperatures in the low- to mid-40s, with mostly clear skies. Throughout the morning temperatures should warm into the 50s and then reach 60 degrees around noon. I’m not worried about any rain, but there should be some wind, perhaps 10 to 15 mph from the south with some higher gusts. This will nudge dewpoints up, but it won’t be anything too uncomfortable. The next front arrives Sunday night.

Next week

Much colder weather is on the way, starting next Monday. There are some key questions such as how cold is it going to get? And is there a chance of snow or sleet on Monday? In terms of temperatures, there’s a solid chance that Houston drops into the mid-20s and sees a hard freeze. I don’t feel overly confident in that, but it’s a distinct possibility. I’ll dig more into that tomorrow, when hopefully there’s some more forecast clarity, and precautions you’ll need to take. We also can’t rule out some freezing precipitation, but overall chances look fairly low for that. In any case, our region’s coldest weather in more than a year is on the way.

Hi everyone. I hope everyone is enjoying this gray and windy day. We’ve seen scattered showers and a few thunderstorms through the morning and early afternoon hours, but nothing too serious.

Our main focus of concern is the development of storms this afternoon along a warm front draped just to the west of Houston. Additional daytime heating, and the approach of a cold front from the northwest, should create a line of storms that will move rapidly from west to east across the area. The National Weather Service has issued a tornado watch for the entire metro area due to the potential for some supercells to develop.

This line of storms should reach areas such as Katy and The Woodlands around 3 to 4 pm CT, pushing into central Houston including downtown and Sugar Land between 4 and 6 pm, and reach the coast shortly after sunset. As the front passes we’re going to see strong, and potentially damaging winds. There is the possibility for a tornado or two to develop, and also perhaps some hail.

I want to be clear: The overall conditions in the atmosphere are not super-supportive for severe weather. But the potential ingredients are there for some severe thunderstorms to come together, albeit briefly, this afternoon. Please be weather-aware if you are out and about. Some additional light to moderate rain will be possible tonight after the front passes. It will be a windy and chilly night, with temperatures quickly dropping into the 40s after midnight.
