Soggy at times this weekend; watching tropics

Posted by Matt Lanza at 6:02 AM

As Eric has been conveying, this weekend is not going to be the most optimal for the Houston area. We’ve got rain chances in abundance. Thankfully, we don’t anticipate any serious problems from the rain, but if you have outdoor plans this weekend, you may need some alternative options. Let’s walk through it.


Yesterday saw a good bit of rain mostly south of the metro area, down toward Wharton and Angleton and west toward Brookshire, with a few storms here and there elsewhere.So far, quiet this morning, with just a few showers down in Matagorda County. As the day goes on, I would expect scattered showers and storms to fire up with daytime heating, beginning at the coast and spreading inland. Not everyone will see rain, but those that do could pick up a quick half-inch to inch of rain in a cooling downpour.

Expect highs near 90°, but a little cooler if it happens to rain a bit more at your location.

Weekend & Monday

So, let’s start with this: I don’t think this weekend will be a complete washout. If you have outdoor plans, I might not completely abandon them. But I would absolutely have an alternative in place. I think Saturday may be a better day than Sunday, unless you live northwest of Houston. It won’t rain all the time and everywhere this weekend, but where it does rain, it may be heavy at times with some patchy street flooding possible.

Who are we expecting to see the most rain on which day? There will be a weak cold front draped inland over Texas. No, it won’t usher in cool, dry air, but it will act as a focal point for the rains. On Saturday it may be well north and west of the city, out toward Columbus and north to College Station and over into Walker or Madison Counties. By Sunday, it creeps closer to Houston.

The NWS rainfall forecast through Sunday evening is just shy of 1″ on average in most of the Houston area, but there’s a better chance at over an inch both along the immediate coast and northwest of the city. (Weather Bell)

I still think the focus of showers on Sunday may be to the northwest of Houston, but perhaps out toward Katy and up to The Woodlands and toward Livingston, so a bit closer. So it’s conceivable that both days, the majority of the rainfall stays northwest of the Houston area. We’ll still see some scattered showers and storms regardless though.

On Monday that front may creep through the area while falling apart. So, again, scattered to numerous showers and storms with daytime heating, now across the Houston area. Look for temperatures to top off in the upper-80s most days on average (90+ if you don’t see rain, cooler if you see a good deal of it), with lows in the mid-70s.

After a wild Labor Day that saw Galveston and coastal communities see upwards of five to ten inches of rain or more, we’re starting with more rain down that way today. But we do have good news for those ready for a break.


Radar this morning as of showed a narrow band of heavy rain pointed onshore across Galveston Island and the southwest end of the Bolivar Peninsula, now inland as of 5:50 AM to about League City. Additional moderate to heavy rain had prompted another Flash Flood Warning just outside of Port Arthur.

Radar as of 5:50 AM showed heavy rain southeast of Houston, just inland from Galveston, along with steady rain just west of Port Arthur. (GRLevel3)

Some of the rain near Port Arthur may try and come a bit west, so folks on the east side of I-45 could see a steady moderate to occasionally heavy rain for a time. Locally heavy rain will continue at times near Galveston, which could cause some relapse in street flooding again. A Flash Flood Watch is posted for the coastal counties through today.

Further inland, including most of Houston, we’ll see a smattering of showers and thunderstorms around the region this morning and afternoon. Look for gradual improvement later today. Clouds and showers will hold back temperatures once again. We only hit 78° officially on Labor Day, our coolest day since the Fourth of July, and only the second time we’ve failed to hit 80 degrees since late April. It feels like it’s been hot forever. Who’s ready for a cold front? We’re looking hard for one, but alas, we don’t see much chance of that happening over the next ten days or so at least.

Wednesday & Thursday

Both days look like a return to more typical late summer weather, with a daily shower and storm chance driven by the sea breeze off the Gulf and daytime heating, so mostly of the hit or miss variety. Any storms will be capable of heavy downpours of course, but coverage should be fairly average for this time of year; a bit less intense than we’ve seen the last couple days. Look for mid- or upper-80s where we see some storms on those days and upper-80s to low-90s in drier locations.

A mostly quiet mid-August week ahead

Posted by Matt Lanza at 6:20 AM

Good Monday morning! Matt here this morning, covering for Eric. Thanks again to Eric for covering me in my opening days of fatherhood. Thanks to all for the comments and well wishes over the last couple weeks. I apologize for any typos, though I’ll blame it on the lack of sleep.

The Houston area has seen repetitive rounds of thunderstorms over the last week and change, but as someone who has been shut out most of the time, I’ve taken notice that the total rainfall distribution has been somewhat erratic.

Rain totals this month have been somewhat erratic around the region. (Harris County Flood Control)

Some areas have seen as much as three to five inches of rain this August, while others have seen a tenth of an inch or less. The winners appear to be in eastern Harris County and also up toward The Woodlands southwest toward Cypress. Waller County has done well also. So it’s been feast or famine for much of the region in August. Looking ahead to this week, the faucet will slow to a trickle for a couple days, and mostly typical August weather sets in.

Today & Tuesday

Our weather pattern has begun to change a bit, as high pressure and dry air begin to flex overhead. This should significantly limit storms in our area this afternoon. Expect high temps in the mid-90s. On Tuesday, we’ll see more of the same, though the rain chances may not be quite as limited. So, we’ll call it just a slight chance of showers. More mid-90s are expected.

There was a good bit of Saharan dust in the skies yesterday. Expect more of that today. Dust will slowly thin out on Tuesday and Wednesday. Air quality will be poor. This sort of thing will be worst for those with respiratory ailments. It’s also not optimal for those of us with regular seasonal allergies. The good news is that Saharan dust outbreaks tend to have peaked by now. So these events should become a little less frequent and intense as we move forward.

Wednesday through Friday

Typical August weather in Houston can be expected to round out the week. Temperatures will probably be one or two degrees cooler than usual, but that will hardly be noticeable to most of us. We’ll peak with highs in the mid-90s and lows in the upper-70s.

Scattered storms set for Father’s Day in Houston

Posted by Matt Lanza at 9:00 AM

Good morning, and happy Father’s Day to those celebrating today. For the most part, the forecast is on track as we’ve been describing it for several days now, but there are a couple things to keep tabs on. And if your travels will take you well south of the area, more toward Corpus Christi, you’ll want to keep a closer eye on the weather. Let’s jump in.

Quick Summary

Here are a few bullet points with the main takeaways that we want to convey today.

  • Scattered storms will develop today for much of the area with locally heavy downpours. Probably not a total washout, but you’ll dodge raindrops.
  • Heavier rains likely tonight and Monday, particularly southeast of downtown Houston. Areas of street flooding will be possible in heavier downpours.
  • Heaviest rain chances should move off to our southwest for midweek, but rain chances stay elevated in and around Houston.
  • Total rainfall of two to four or five inches will be the average across the entire area through midweek. There will be smaller, isolated pockets that see higher amounts upwards of seven, eight, or nine inches, most likely closer to the Bay Area or Galveston.


As of about 8-8:30 AM Sunday, the Houston area is all quiet. We have a few isolated showers, mainly south and east of downtown Houston. And for much of this morning, we’ll be fine with just a couple downpours.

A radar loop early Sunday morning shows just some sporadic showers, with some heavier rain offshore of Louisiana. (College of DuPage)

Meanwhile, looking at a bigger picture view of things, satellite this morning shows our disorganized disturbance in the Gulf of Mexico now. Heavier thunderstorms are occurring well offshore. This is what we’re watching for tonight and Monday.

More organized thunderstorms (not an organized tropical disturbance) are offshore in the Gulf of Mexico. Those should arrive in our area later tonight and Monday. (Tropical Tidbits)

In terms of tropical development, the National Hurricane Center continues to carry a token 20% chance over the next 48+ hours. That’s a fair assessment, and we feel that impacts to our area will be similar regardless of if this thing meets technical definitions or not within the next couple days.

Rest of Sunday

So what can we expect for the rest of today? Well, as this disturbance creeps toward Texas, expect numerous showers and thunderstorms to pop up late this morning and afternoon across most of the area. I’m not going to classify Father’s Day afternoon as a complete washout, but you will likely be dodging raindrops at least once, if not a few times this afternoon. So if you are planning anything outdoors, have a backup plan. Most of the area will see a couple tenths to maybe a half inch of rainfall. Some will see less, and some may see in excess of one or two inches where rains are most persistent. Today’s rainfall will be a nuisance more than anything for most folks.
