A few stormy, slightly cooler days before some proper summer heat arrives

Good morning. So far we have eased into summertime this year. For the entire month of May, temperatures ended up slightly below normal. And the first several days of June trended cooler as well. That party, I am sorry to say, should end this week.

By Thursday or Friday, as high pressure builds over the region with a warm southerly flow, I expect high temperatures to reach the mid-90s and stay there for awhile. This will be the beginning of what I like to call “Mid summer” in Houston, the second of our four phases of summer.

Monday

But we’re not there yet. In the absence of high pressure, and with a moderately disturbed atmosphere, we’ll see decent rain chances for the next few days. The potential for showers and thunderstorms will be highest today, with 60 to 70 percent coverage during the afternoon and early evening hours in Houston. Rainfall amounts will be highly variable, but on average most locations should pick up 0.25 to 1 inch of rain, with perhaps areas south of Interstate 10 seeing slightly higher accumulations. As these storms may be hitting about during rush hour, take a little extra care in getting home this evening. These showers, along with mostly cloudy skies, should limit highs to the upper 80s. Rain chances are lower overnight, with lows falling to around 70 degrees.

Tuesday

This day should be similar to Monday, in terms of showers popping up during the afternoon hours. However, I expect less coverage of storms. Skies will be also be partly sunny, so highs may nudge up to 90 degrees in some locations.

Wednesday

This is a bit of a transition day. We’ll still see some showers, but as we’re moving to a hotter and less rainy pattern, look for partly to mostly sunny skies and highs in the low 90s.

Thursday and Friday

Rain chances will fall back to about 20 percent each day, with just a slight chance of a sea breeze shower in the afternoon. Otherwise expect mostly sunny skies and highs in the low to mid-90s.

Saturday, Sunday, and beyond

The forecast period from this weekend into the middle of next week simply looks mostly sunny and hot, with high temperatures in the mid-90s. While we can’t entirely rule out rain chances, the pattern does not look to produce much in the way of precipitation. As I said at the outset, summer proper is on the way.

Saturday night surprise sets the stage for occasionally stormy weather through midweek

Good morning. Just jumping in here with a quick Sunday morning update. Yes, a line of fairly strong thunderstorms moved through the Houston area during the overnight hours. No, we did not anticipate them being quite so strong, or arriving quite so early. Sorry for the late-night wake-up call.

The good news is that the overnight storms sapped the atmosphere of much of its energy, and this should lessen thunderstorm activity today. I would expect mostly cloudy skies to prevail, with highs of about 90 degrees or just above, and moderate to high humidity. Your overall chances of seeing a shower or a thunderstorm this afternoon is probably about 30 percent. These rain chances will continue this evening, and during the overnight hours, but at this point I don’t see much sign of a similar flare-up of storms late tonight like the region experienced on Saturday night.

With that being said, the overall pattern this week favors additional showers and thunderstorms through about Wednesday, as disturbances move down from the north into our region. I don’t have much confidence right now in whether these will occur during the daytime, along with atmospheric heating, or at nighttime. Rain chances will go down, and temperatures up, toward the end of the week.

More tomorrow.

Rain chances ease back into Houston’s forecast this weekend

Happy Friday! We continue to see humidity running a little below average for this time of year in Houston, which may be <laughs mockingly> hard to believe, but it’s true! This weekend, we’ll see shower chances slowly re-enter the forecast, especially Sunday, as we heat up temps to 90 or a bit hotter.

In the tropics, yesterday started hurricane season and right on cue Tropical Depression 2 formed. It is not a concern for Texas and will just help to offer enhanced rainfall in Florida and Cuba. Read all about it on our new companion site, The Eyewall. Thanks to all who commented, liked, shared, and subscribed to our posts there. Keep spreading the word. We’ll be using The Eyewall to cover the entirety of the Atlantic basin just like we cover Houston here, a duty to which we remain fully committed!

Today

Look for sun, minimal rain chances, and temperatures around 90 degrees, give or take. We continue to battle air quality issues, and today is (again) an ozone action day, so please use caution if you’re in a sensitive group. We may see some improvement over the weekend. I don’t know that this is abnormal, but it sure has felt excessive since early May, something we know you’ve noticed.

Rain chances are not zero, but they are rather low today. Still, you can never entirely rule out an isolated downpour in June.

Saturday

For the most part, Saturday should be a repeat of today. However, rain chances may be more like 10 to 15 percent versus the 10 percent or less that they are today. This may be especially true north of Houston. Expect morning lows in the upper-60s to low-70s, with a daytime high of 90 or better in most spots.

Sunday

Rain chances bump up for Sunday late morning or afternoon. Look for sun, some clouds, and temperatures near 90, after a morning low near 70 degrees or a touch warmer. Isolated to scattered showers and storms are likely to fire through the day, with some areas seeing an inch or two of rain and others seeing nothing. Coverage should be somewhere at least in the 30 to 40 percent range.

Temperatures over the next week or so will reach their bottom with higher rain chances Monday and Tuesday before slowly creeping back up toward next weekend. (Weather Bell)

Next week

Look for additional isolated to scattered showers and storms on Monday and Tuesday. Things should gradually ease back to slight, hit or miss rain chances by later in the week. So your best odds of rain right now are Sunday through Tuesday. But even then, some of us may not see much, while others may get a few rounds of showers or storms. It will be an irregular pattern of rain. Look for temps to lull a bit early in the week due to clouds and showers, before warming back up later in the week. Rain chances should back off some after Tuesday or Wednesday, but we’ll see if that trend holds.

Hurricane season begins today, and we’re launching a website dedicated to tracking Atlantic storms

Good morning. Today marks the beginning of the Atlantic hurricane season, which will last for the next six months. It’s also a big day for Matt and myself, as we’re launching a new website devoted to tropical weather in the Atlantic Ocean, Gulf of Mexico, and Caribbean Sea. It’s called The Eyewall, and you can head over there now to check it out, and find out more information about what we’re doing. But I’m sure some readers will have questions about what this means for Space City Weather, and that’s what I’m going to address now.

Is Space City Weather going to change?

No.

Like not at all?

Like not at all. Matt and I are 100 percent committed to Space City Weather, and improving it every way we can. To that end, look for an updated version of our app soon, that squashes some bugs and delivers the much-asked for dark mode feature in addition to other goodies.

Why are you doing this?

There are two primary reasons. One, much of the current national hurricane coverage is sensationalized, and we think there is room for a different, no-hype approach. And two, we are frequently asked for local sites during hurricane season. (I.e. my mom is in Destin, where can she get this kind of coverage for Tropical Storm X or Hurricane Y) Well, now we’ve got an answer. We’re counting on you to tell friends and family beyond Texas.

Will there be cross-over between the two sites?

A little bit. The Eyewall will publish a “Daily Tropical Outlook” every weekday, and weekends as needed. There will be other hurricane content as well, and lots of coverage of active storms threatening land. Once a week we will cross-publish one of these “tropical outlooks” on Space City Weather (i.e. like with our weekly tropics report).

What happens if a hurricane threatens Texas?

For Space City Weather we cover the storm as usual. The local material would then be cross-posted onto The Eyewall. But our intent is that for readers of Space City Weather there will be no noticeable changes. We will not be publishing content from the Eyewall about storms affecting other parts of the country, or Mexico and the Caribbean Islands here, although we may link to it from time to time on Space City Weather.

Do you have a sponsor?

Not yet. Really, this is an experiment. Matt is taking on a big extra burden with this, and while we’re going to have some contributors, we want to see if this is sustainable. We also want to see if there are readers for this. Maybe it flops. Maybe it doesn’t. Really, we just want to give people some comfort in a terribly trying and traumatic time in their lives. We’ll see.

Now, onto the forecast…

Thursday

Our weather for the next few days will be guided by a modestly strong ridge of high pressure. This means we’re going to see warm and sunny weather. Highs today should reach about 90 degrees, with light southeast winds. One nice aspect of the weather is that dewpoints have not reached hair-melting levels yet, so the humidity won’t be oppressive. Lows tonight drop into the low 70s. Rain chances today are about 10 percent.

Friday

A little warmer, with highs in the low 90s. Otherwise, pretty much the same as Thursday.

Saturday

Another day with mostly sunny skies and highs in the low 90s. For areas far north of Houston, likely even north of Conroe, there is a slight chance of some rain showers later in the day.

Sunday and Monday

As high pressure eases off, skies will become more cloudy in response to rising atmospheric moisture levels, and our rain chances will go up. Both Sunday and Monday should see about a 50 percent chance of rainfall, with accumulations in the order of 0.25 to 1 inch. Overall chances are probably a bit higher north of Interstate 10, but this far out I don’t have great confidence in that. The clouds should bring highs back down to around 90 degrees on both days.

Later next week

Rain chances continue for a few more days, helping to tamp down high temperatures. But it’s possible that we’re headed toward the low- or even mid-90s by later next week. Hello, June!
