Dewpoints starting to rise ahead of Saturday storm chances in Houston

Summary: After a few days of gorgeous weather Houston’s pattern has begun to change with a more southerly flow. By late Friday night this is likely to produce some showers and thunderstorms, which will likely peak in activity on Saturday morning. Then we should see sunny and cooler weather through the middle of next week.

I also want to thank everyone for their kind words about our sponsorship agreement with Reliant, and the slight tweaks in our site design. Essentially we’ve changed the font for headlines, and updated the header image at the top of the page. For those who don’t know, I essentially created Space City Weather on a Friday night in October 2015, in a few hours, ahead of some storms. So the (now dated) header image was rushed. I grabbed a NASA image of the Space Shuttle carrier aircraft flying over the Houston skyline, cropped it, added some text, and called it done. The new design looks more professional and updates the “space” iconography to the International Space Station. I loved the Shuttle, but it did retire 12 years ago. Our friends and neighbors are flying on the station at this very moment, so it embodies Space City.

A southerly flow is now firmly in place for the next couple of days. (Weather Bell)

Thursday

After some patchy fog lifts this morning we’re going to see a partly sunny day. Temperatures will again be mild, reaching about 70 degrees. As mentioned above, the winds will be from the south at 5 to 10 mph, and this will start to raise humidity levels a bit. But with dewpoints in the 50s it will still feel reasonably dry. Lows tonight will drop into the mid-50s.

Friday

Temperatures will again rise to around 70 degrees, or just above. Skies will be partly sunny. It will be a little more humid than Thursday, and a little more breezy. But still nice. While I can’t entirely rule out some light showers on Friday evening, I think the rain will hold off for the most part until after midnight. So any Friday evening activities you have look good to go at this point.

Saturday

An upper level disturbance, along with the next cold front, will begin affecting our weather early on Saturday. While we’re not fully in the realm of high resolution modeling yet, my sense is that we’ll see on-and off showers and thunderstorms overnight, with a line of storms pushing through some time on Saturday morning. After this line of storms we may see a few lingering showers into the afternoon hours.

How strong will the storms be? As there will be a fair amount of shear, I can see the potential for some damaging winds. The other concern is heavy rainfall. It still looks like most of the area will see 1 to 3 inches of rainfall, but the good news is that the storms are likely to be fairly progressive in moving from west to east. So I don’t see a whole lot of training. The potential for heavy rainfall is generally greater to the east of Houston.

Drier air will start to filter into Houston on Saturday afternoon, so we should see at least some partly sunny skies later in the day. Temperatures will likely be in the upper 60s. Lows on Saturday night will drop to around 50 degrees in Houston, with cooler conditions for outlying areas.

Sunday

Sunday looks sunny and pleasant, with highs in the upper 60s—but there’s a catch. We’re going to see an additional push of cooler and drier air, and this will result in a windy day, with gusts up to about 30 mph from the north. These winds will persist overnight, when temperatures drop into the 40s, and Monday morning.

Next week

We’ll see sunny and cooler conditions, with nights in the 40s, through the middle of the week. After that daytime temperatures will warm into the low 70s, probably, into the weekend. Conditions look mild throughout, with a slight chance of rain returning by next Saturday or Sunday.

Reliant extends its sponsorship of Space City Weather for three years—here’s why that matters

Hi everyone. Matt and I are excited to announce a three-year extension of our long-running relationship with Reliant, which will extend their exclusive sponsorship through 2026. As some of you may recall, they came on board a few months before Hurricane Harvey in 2017, and we’ve never looked back. Houston is Reliant’s hometown, their president Elizabeth Killinger and their employees are avid SCW supporters, and they totally get what we’re about. (She and I filmed a video you should check out). This is great news for readers as well, because Reliant could not be a better partner to keep Space City Weather powered up for years to come.

Here’s why: 

Clean interface: Thanks to this sponsorship, we never have to run any intrusive advertising on this website. That means no autoplay video garbage. No pop-ups. No tracking. None of that nonsense. Instead, you’ll see tasteful branding on our pages and in our products, and the (very) occasional sponsor message that provides useful information on energy efficiency or new initiatives. Seriously, Reliant is an awesome, hands-off sponsor that lets us focus on what we do best.

No hype: Because of the nature of our agreement, we don’t feel pressured to chase clicks for the sake of chasing clicks. We are not getting paid for the traffic we generate. (Typically, online advertisers pay per impression on readers). This is why you sometimes see sensationalist content online. It sells. Anyway, we’re empowered to simply write what we think needs to be written, and nothing more. There will be some Mondays when we tell you to ignore the forecast for the rest of the week, and Reliant is fully supportive of that. 

Cool stuff: Thanks to our sponsorship, we’ve been able to do some pretty cool stuff. A recent example that comes to mind is hosting a Fall Day celebration the last two years. Reliant has entirely underwritten these events and organized them for us. We’ve also done some great giveaways, including four full air conditioning systems, Houston Astros tickets and jerseys and more. All of this is in partnership with Reliant and their team is behind it all. It brings an element of fun to the awesome community we’ve built here. 

Certainty: With a three-year agreement, we can continue to invest in Space City Weather, our app, and other initiatives. And we’re already making plans to do just that. We’re not going anywhere, and it’s great to have Reliant at our side.

So yeah, we’re pretty pumped to continue working with Reliant in the coming years.

A couple of more fine days before some rain showers Friday night and Saturday

Summary: The forecast remains largely the same, as we’ll see gradually warming and generally mild weather through Friday. Beginning Friday evening, and lasting into Saturday afternoon, there will be an elevated chance of rain showers and thunderstorms as the next front passes through. This front will bring us cooler and drier air through the middle of next week.

Also, be sure and check back later this morning for an important site announcement!

Wednesday

Today will bring more mostly sunny, pleasant, and fine conditions. Expect highs of around 70 degrees with light westerly winds. The winds of change will begin to blow, if only slightly, tonight as they shift to come from the south. This will herald the beginnings of an onshore flow, but temperatures will still drop to nearly 50 degrees overnight.

Thursday

Expect another nice day, with partly sunny skies and highs of around 70 degrees. The air will be a little bit more humid, but we’ll still be fairly dry. Winds will be a bit more pronounced from the south. Overnight lows will drop into the mid-50s.

Friday

Skies will be partly to mostly sunny, with highs in the mid-70s. I think rain chances will hold off during the daytime, and probably most of the evening as well. But some time on Friday night, perhaps after midnight, we’ll see showers and thunderstorms advance into the Houston metro area from the west.

Saturday

We’ll get a better handle on the details in the next day or two, but we can expect widespread showers through the morning hours and into the early afternoon. In terms of accumulations we’re looking at 1 to 3 inches, which is not a whole lot, but our grounds are still pretty wet from rains last week. Highs on Saturday should be about 70 degrees, with clearing skies likely during the afternoon hours. Lows will likely drop to around 50 degrees on Saturday night as humidity levels drop behind the front.

Pretty much all of East Texas will pick up 1 to 3 inches of rain from the front. (Weather Bell)

Sunday

This will be a colder and drier day with sunny skies. It does look windy, with gusts up to 30 mph from the north. Highs will top out in the 60s, with overnight lows dropping to around 50 degrees overnight.

Next week

Monday, Tuesday, and Wednesday all look cooler with highs in the 60s and sunny skies. We should see the return of more clouds and warmer temperatures with highs in the 70s toward the end of next week. There’s no strong signal for rain after Saturday.

A way-too-early post on whether Houston is done with freezes for this winter yet

Summary: Houston experienced an absolutely gorgeous day on Monday, and we’ve got a couple of more to go this week with dry air, mostly sunny skies, and pleasant temperatures. We’re still looking at a healthy chance of showers this weekend as a front passes, but accumulations look manageable, with 1 to 2 inches in total for most locations. In this post I also want to address the question of whether the region is likely to receive another freeze this winter.

Last freeze

Don’t look now, but January ends in a couple of days. If we look ahead for the next 10 days, I’m highly confident that we’re not going to see freezing conditions. This gets us through the first week or so of February. Then, the pattern looks fairly warm until the middle of the month, when we may see some cooler weather. But how cold? Will conditions turn freezing? At this point I’d lean toward no, but at that point we’re just outside the window of reliable weather forecasting.

Texas should see warmer than normal temperatures during the second week of February. (Pivotal Weather)

The “average” date of the city’s last freeze comes in the middle of February for Houston, with a slightly later date for outlying areas. So my response to those who are asking whether Houston done with freezes yet for this winter is maybe. For areas south of Interstate 10, I might even say probably. But it’s not really a question I’ll be able answer with any confidence for another two weeks or so.

Tuesday

Temperatures are starting out in the 40s for most locations, a few degrees warmer than Monday. (If you were up early, you may have noticed the sunrise was gorgeous. Conditions will favor pretty sunsets for the next few days as well). It’s going to be another fine day, with low humidity, light winds, and a high temperature of around 70 degrees. Seriously, if you can steal some time outside today, I highly recommend it. Lows tonight will be a couple of degrees warmer, dropping into the upper 40s for most.

Wednesday

This will be another fine day with highs of around 70 degrees and some drier air. We may see a few more clouds, but I still expect to see a fair amount of sunshine. Lows on Wednesday night will drop to around 50 degrees.

Thursday

As the onshore flow returns later on Wednesday or Thursday morning, we’ll start to see the air turn a bit more humid. The process will be somewhat gradual, however. Looks for highs Thursday of around 70 degrees, with partly sunny skies. Lows on Thursday night will drop into the mid-50s.

Friday and Saturday

An upper-level disturbance will approach the region on Friday, bringing a healthy chance of rain. At this point there looks to be a chance of showers on Friday evening, but the better rain chances will hold off until Friday night, and Saturday. I’m not expecting anything too crazy, but much of the area should pick up 1 to 2 inches, with higher isolated totals. The best chance for thunderstorms will come Saturday morning, so if you have outdoor activities this weekend please have a back-up plan. Most likely the rains will end Saturday afternoon or evening.

NOAA rain accumulation forecast for now through Sunday morning. (Weather Bell)

Both Friday and Saturday will see highs in the vicinity of 70 degrees, with fairly humid air. It looks like the surface front will arrive sometime on Saturday evening, ushering in drier and cooler air. Look for lows on Saturday night to drop into the 50s.

Sunday and next week

Sunday should be, like its namesake, sunny. Look for highs in the 60s. It also looks breezy, with a northwesterly breeze at 20 mph or so, with higher gusts. Lows on Sunday night will drop into the upper 40s, give or take. We should see highs in the 60s for the first half of the week, before the 70s return by Thursday or so. I think we’ll stay a little warmer for awhile at that point.
