Houston region (mostly) receives much-needed rainfall, with more on the way

In brief: In this morning’s post we recap what was a rather wet weekend for large parts of the Houston region. A mid-week front will bring us another chance of showers followed by a bit of drier and cooler weather. The weekend looks sunny and warm.

A soggy weekend

As expected, the Houston area received widely varying amounts of rainfall this weekend, particularly from Saturday afternoon through Sunday morning. While some areas such as Katy only saw a smattering of precipitation, one only need drive along I-10 to the other side of Houston to find totals of 4 to 6 inches. These east-side showers definitely over-performed our predictions.

There was a time, on Thursday evening and Friday morning, when Matt and I debated whether to issue a Stage 1 flood alert for the area this weekend. In retrospect, we probably should have, because these storms produced some decent street flooding in central Houston and areas to the north and east of downtown.

Although these showers were most certainly a nuisance for people out and about Saturday night, large chunks of Houston received 1 or more inches of much-needed rainfall as we are getting deeper into spring. We used “mostly” in the headline because some areas got a little too much rain, and other areas west of Houston not enough.

I just wanted to include a zoomed-in view (below) of areas hardest hit by rains this weekend, including Highway 90 and the area near George Bush Intercontinental Airport. These were the heaviest rains so far in our region in 2026.

Monday

The weak cold front that moved into the region this weekend is now lifting back to the north, and so we will be left a warm and humid day today. (Also, the fog is back, and will be possible again tonight and Tuesday night). High temperatures today will generally be in the low- to mid-80s, with winds picking up from the south this afternoon and perhaps gusting up to 20 mph. Scattered, mostly light showers will be possible this afternoon, with perhaps 20 percent coverage. Skies will be mostly cloudy.

Rodeo forecast

Any showers that do develop today should be fading by the late afternoon or early evening hours, about the time most people start showing up for the Houston Livestock Show and Rodeo. Accordingly, I’m not too concerned about any showers before, during or after the show. Temperatures will be in the low 70s this evening and not fall much, with overnight lows in Houston likely to settle out at 70 degrees for most locations.

Tuesday

In terms of fog and temperatures, Tuesday will be similar to Monday. And while our skies will continue to be predominantly cloudy, I don’t expect much, if any rain on Tuesday. Our southerly winds will be more pronounced, however, with gusts up to 25 mph during the afternoon. Expect another warm and muggy night, with lows only falling to around 70 degrees again.

Wednesday

This will be another warm day, but a cold front is likely to push into the area during the afternoon and evening. This will bring a healthy chance of showers and possibly some thunderstorms during this timeframe. However storms are no sure thing, as I could see a scenario in which a line of storms forms north of Houston, but is broken (or even non-existent) in the Houston area. We’ll see. In any case some additional showers are likely on Wednesday afternoon and evening (rain accumulations of 0.25 to 0.75 inch maybe). Please note there is some uncertainty in this forecast as storms could develop further to the south, over Houston. Drier air will follow later on Wednesday night.

Thursday

This will be a breezy, spring-like day with a high of around 70 degrees, low humidity, and sunny skies. Lows on Thursday night will drop to around 50 degrees in Houston, with cooler conditions for inland areas.

Friday

This will be a pleasant day as well, with dry-ish air and highs likely in the upper 70s to 80 degrees. Skies will be sunny. Lows on Friday night will only drop to about 60 degrees as the onshore flow resumes.

Saturday and Sunday

The weekend looks sunny and warm, with highs in the low- to mid-80s. Dewpoints will be in the lower 60s so while it will feel somewhat humid, I don’t expect it to be really muggy like our weather of late.

Next week

Another front will probably arrive early next week, pushing our overnight lows back down into the mid-50s, closer to where they should be this time of year. At this distance the overall likelihood of storms with this front looks low, but we’ll see.

Here’s what to expect later today and Sunday from a stalled front that may generate storms

In brief: We interrupt your weekend to bring you an update on impacts from a cool front that will approach the Houston region and stall out. The primary threat is severe thunderstorms later today and on Sunday, although not everyone will see inclement weather.

There is a lot going on in the metro region this weekend, from big events at the Houston Livestock Show and Rodeo to the World Baseball Classic to much, much more. We’re going to need to be weather aware.

In the big picture a cool front move into the region, where it will clash with very warm and moist air. Where this front ultimately stalls will serve as a focus for showers along with potentially strong thunderstorms and heavy rain. However this will be rather location based, so whereas some areas may see 2 or more inches of rain, others will see considerably less. Some uncertainty remains with regard to the details, but generally here is what I expect to happen.

For now the radar is quiet, and we expect it to remain so in Houston throughout the morning hours. During the afternoon we may see some scattered showers across Houston, but nothing serious. However off to our northwest, in the vicinity of College Station, a more organized line of storms is likely to develop around mid-afternoon. This mass of storms is likely to threaten areas within the greater Houston region along and north of Interstate 10 during the evening hours. There is the potential for strong winds and hail with some of these thunderstorms should they turn severe. This threat should persist until around midnight or so.

If you’re headed to the Rodeo on Saturday here’s what I can say. First, the best chance of severe weather should be elsewhere this evening. However, we cannot rule out some showers and thunderstorms during the evening in the vicinity of NRG Stadium. So take care, but at this point I would not cancel plans.

After midnight the focus of storms is likely to turn closer to the coast, particularly areas including Brazoria, Galveston, and Chambers counties—I’m thinking areas nearer to Galveston Bay. For these coastal areas rainfall will be more likely during the pre-dawn hours on Sunday and during the daytime. (Rain chances for areas north of I-10 will not be zero on Sunday, but for now they look to be considerably lower). On Sunday the dynamics for severe weather are less favorable, but I still expect to see some pockets of heavy rainfall within stronger storm cells.

In terms of temperatures expect warm and muggy conditions on Saturday, with slightly cooler temperatures in the 70s on Sunday for most of the region. Rain chances diminish some on Monday.

If there are significant changes to the forecast we will update accordingly.

As temperatures warm, here are some energy efficiency tips from our partner, Reliant

In brief: In this sponsored post, we share some energy tips from Reliant, a long-time partner of Space City Weather who helps keep the lights on here so we can keep on doing what we’re doing.

It has been a warm start to the year. February, in particularly, was sultry for the end of winter. The month finished with an average temperature of 63.8 degrees, which ranks as the fourth warmest February on record in Houston (February 2017 ranks highest, at 66.4 degrees). March has started out very warm as well, with an average temperature of 72.9 degrees, which is nearly 12 degrees above normal.

Given the warm start to the year, and that today is World Energy Efficiency Day, we thought it might be a good time for a reminder that smart energy choices now can help keep homes comfortable and bills in check as summer approaches. To mark the day, Reliant is sharing simple, cost‑conscious tips to help manage energy use more efficiently this spring heading into summer.

Home improvements

With warmer days already settling in, now is a smart time to tackle quick home fixes that can improve efficiency and help limit cooling costs as temperatures continue to rise.

  • Adding more insulation to your home can be among the most cost-effective improvements you can make. Make sure every part of your house is insulated and add more if needed; spray foam insulation is great for getting into all the nooks and crannies.
  • Inspect ductwork for loose connections or damaged insulation as leaks can waste up to 30 percent of cooled air.
  • Schedule a spring tune‑up to ensure the AC system is ready for high demand.
  • Replace or clean air filters every 30-60 days, as a clean filter can reduce AC energy consumption by up to 15 percent. 

Streamline your energy use

As AC use ramps up earlier in the season, small, smart energy choices can help keep homes comfortable while managing monthly bills.

  • Follow the 4×4 rule by raising your air conditioning temperature 4 degrees if you’ll be away from home 4 hours or more.
  • Do laundry more efficiently by using cold water and air drying bedding and clothing. 
  • Run ceiling fans counterclockwise to push cool air downward. Use fans first before turning on the AC. 
  • Grill outdoors when it’s nice out. Cooking indoors raises the heat, requiring the AC to use more electricity.
  • Open windows at night to let cool air in, then close them in the morning to trap the cool air.

In terms of storms and timing, here’s how we think this weekend’s weather will unfold

In brief: In today’s post we discuss the recent and ongoing sea fog as well as our warmer than usual temperatures. Then our attention turns to the likelihood of storms this weekend as a front sags into Houston and brings much needed rain.

But first, some chat about fog on the blog

Are you tired of the fog yet? I know some readers like the eerie quality or semblance of “stillness” that fog brings. But if you need to be out and about late at night or early in the morning, it can be a real hazard. We’ve been seeing frequent fog near the coast this week, and this “sea fog” is due to the warmer air moving over cooler surface waters near the shore. Unfortunately, with the warmer temperatures we are likely to see through the weekend, sea fog will remain a persistent threat during the late evenings through mid-mornings for some coastal locations.

Thursday

Cloudy skies this morning will give way to partly sunny skies this afternoon, with high temperatures likely topping out in the low- to mid-80s. This will depend on the extent of sunshine at your location. We did see a few very light sprinkles on Wednesday in parts of Houston, but I feel like, overall, our chances for rain today will be pretty close to zero. Humidity levels will remain rather high for this time of year.

Rodeo forecast

It’s going to be fairly warm this evening, with temperatures in the upper 70s. The other defining feature that rodeo goers will experience is gusty southerly winds, perhaps up to 25 mph, although these will die down as the evening progresses. Temperatures after the show will be the in the 70s, only falling to around 70 degrees by early Friday morning.

Friday

This day will be rather similar to Thursday, with two possible changes. First of all, those southerly winds might be even a little bit stronger, gusting up to possibly 30 mph from the south during the afternoon. The other difference is that there is perhaps a 30 percent chance of light showers during the daytime or evening. Lows, again, will be very warm for early March.

Saturday and Sunday

So will the weekend bring a rain-o-rama? It’s still a little difficult to pin down precise details, but roughly speaking here’s what I think will happen. Saturday will be another warm and humid day like those preceding it. There will be a better chance of light daytime showers, perhaps on the order of 30 percent. But I don’t expect these to be significant or disruptive.

On Saturday afternoon or early evening a (dying) front is going to approach and potentially move into the Houston metro area. I expect there to be a goodly number showers and thunderstorms with this front. Whether these storms make it all the way to the coast will depend on where the front stalls, but at this point I think there is a decent chance of everyone seeing some rain. I’m hopeful, for the purposes of our spring vegetation, that we pick up 0.5 to 2 inches this weekend, with higher isolated totals, but again some uncertainty remains.

Severe weather outlook for Saturday and Saturday night. (NOAA)

I mentioned thunderstorms and there is slight risk for some severe weather with this front as it moves in and stalls, and again I think the most likely timing for this is probably Saturday evening. So bear that in mind if you’re planning to be out and about.

Sunday, for much of the region, should be a few degrees cooler due to widespread cloud cover, the aforementioned front, and ongoing rain chances during the day. The potential for thunderstorms and severe weather should be diminished however. The bottom line is that from Saturday afternoon into Sunday morning we’re going to need to be mindful of the possibility of thunderstorms and heavy rainfall, but I’m not saying everyone will see these conditions.

Next week

Monday, Tuesday, and Wednesday of next week will see ongoing warm temperatures, with highs in the low 80s and mostly cloudy skies. There will be a modest chance of daily rain chances. A front should arrive some time on Wednesday to bring us clearer skies and drier air and probably a few nights in the 50s. Two weeks into March it may finally feel like March.
