Heat and minimal rain chances through the weekend

Posted by Matt Lanza at 6:37 AM

Good morning. Yesterday was the 16th day this month that we officially hit 95° or hotter in Houston. The last time we did that was 2013. At least this isn’t a repeat of 2011, when we did 95+ on 26 occasions. We will continue to flirt with 95 degrees for the final three days of June. More on that in a second. Below today’s forecast, we’ve got some analysis on the National Weather Service post-Harvey service assessment that was released last week. I farmed out some interesting tidbits for you that may be of interest. First, the forecast.

Today & Friday

More hot weather is in store for us over the next couple days. We had a handful of showers in the region yesterday, and we’ll probably have a handful more today. However, atmospheric moisture looks a bit more robust today than it did yesterday, so that should yield a slightly larger handful of showers than Wednesday. That said, we’re talking like 20 percent chances at best here. Basically, if you see a cooling shower today or tomorrow, consider yourself fortunate.

Temperatures will peak around the middle 90s once again both Thursday and Friday.


Shower chances continue to look like they’ll dwindle to near zero this weekend. With that, expect more hot weather. Officially, high temperatures should reach the mid-90s both Saturday and Sunday. Take it easy outdoors, as it will continue to be quite humid and uncomfortable.

As noted yesterday, we will also be dealing with Saharan dust. Skies will be hazy or gray looking at times, despite sunshine. And again, if you have any respiratory ailments or bad allergies, you may want to take it a little extra easy this weekend, as air quality could be a little worse than usual.

Just to clarify, as we’ve gotten a handful of interesting questions, this isn’t a dust storm or big, unique event for us. This happens at least a few times a summer usually. The vast majority of us will notice more haze than usual and the color difference to the sky. Maybe, if we’re lucky, the sunsets and sunrises will be more vibrant, though I’m happy to put a Texas sunrise or sunset up against anyone’s on a normal day. Sometimes, too much dust can have the opposite effect and dull the sunsets or sunrises a bit.

The only real “impact,” per se, is the slight increase in particulate matter, which is why if you have bad allergies or other respiratory ailments, we encourage you to take it easy. It’s certainly meteorologically interesting and a nice reminder of how fascinating this marble is that we inhabit to realize that you’re seeing dust in the sky in Texas that’s come all the way from Africa.

Next week

We do still look to be on track for a change next week, though the details are very uncertain. We’ve got high confidence in Monday still looking a lot like the weekend, with some haze and plenty of heat and humidity. By Tuesday, a disturbance aloft will be approaching western Louisiana, perhaps generating slightly better storm chances east of Houston toward Beaumont or Lake Charles. After about Tuesday afternoon, forecast confidence trends downward. Wednesday will probably see our storm chances peak in the Houston area and just east, but depending on the speed and trajectory of next week’s disturbance, that could easily get pushed back to Thursday.

A disturbance in the upper atmosphere will help boost rain chances at some point next week, most likely between Wednesday and Thursday. (Tropical Tidbits)

So before you go cancelling any plans, just know that as of right now we don’t expect a washout on the Fourth of July yet, just a better than average chance of storms. That said, yes, if you have outdoor plans you want to stay tuned to the forecast, as this could shift one way or another pretty easily. More on this tomorrow.

Post-Harvey week in review: December 18, 2017

Posted by Matt Lanza at 1:49 PM

It’s another Monday, so it’s time for another week in review of articles about Harvey-related issues in Texas. If you missed previous recaps, they are here:

Post-Harvey week in review: December 11, 2017
Post-Harvey week in review: December 4, 2017
Post-Harvey week in review: November 27, 2017
Post-Harvey week in review: November 20, 2017

Just as a note: With Christmas and New Years upcoming on Mondays, we’ll table this feature until next year. Look for this to resume in early 2018.

Reads of the week

The Houston Chronicle’s “Developing Storm” series. Parts one and two are linked in last week’s post. The next three parts are linked below. There should be two more coming soon. These are very much worth your time to read, as they’re educational, informative, and, at times, maddening.

Part 3: What’s in Houston’s worst flood zones? Development worth $13.5 billion (Houston Chronicle): Since 2008, 1,400 structures worth $4.2 billion have been built on floodway parcels in Harris County. Part 3 of the Chronicle’s seven part series examines the differences between floodways and floodplains and how Houston’s regulations have evolved (or haven’t) despite our experience with frequent floods over the years.

Part 4: Harvey overwhelmed some levee systems. Future storms could do worse (Houston Chronicle): Levee systems protecting subdivisions in Fort Bend County probably performed as they were supposed to, but that didn’t prevent over 100 homes from being flooded during Harvey. And by no means do levees guarantee future protection from flooding.

Part 5: Officials patched and prayed while pressure built on Houston’s dams (Houston Chronicle): Addicks and Barker Dams have done enormous service to Houston. Learn about their history and learn how much trouble Houston would be in if they were to fail.

Flooding fact sheets

Continuing on the idea of educating and informing Houston residents: The Greater Houston Flood Mitigation Consortium has published fact sheets to help people in the Houston area better understand terms, technicalities, and flooding risks. Four of them are linked below.

How to assess flood damage

Welcome back to our weekly Monday wrap-up of Harvey and flooding-related news you may have missed over the last seven days. Let us know if we missed anything in the comments. Previous recaps are here:

Reads of the Week

Sunk Costs – Back-to-back record flooding along the Brazos River has forced people in Richmond to make an excruciating choice: Stay or go? (Texas Observer): The Brazos River at Richmond has seen four of its 10 highest crests on record since May of 2015. Some residents have flooded multiple times, and they now grapple with the question of where to go from here.

Developing Storm Part 1: Nature ruled, man reacted. Hurricane Harvey was Houston’s reckoning (Houston Chronicle): A multi-part series from the Chronicle began last week, and it aims to discuss the storm in the context of it not being exclusively a *natural* disaster. It’s worth reading. The first part discusses the reactions and decisions that had to be made in the heat of battle.

Developing Storm Part 2: Build, flood, rebuild: flood insurance’s expensive cycle (Houston Chronicle): Part two of the Chronicle series talks about the history of the National Flood Insurance Program. It discusses in depth how Congress has failed to act to make NFIP more fiscally viable.

Surveys & Symposiums

Survey: Harvey’s wrath affected 66 percent of Texans in its path (Corpus Christi Caller-Times): Two-thirds of people surveyed in counties affected by Harvey report that they have some sort of damage from the storm. They also report that help hasn’t quite been adequate to this point.

Report: An uneven recovery after Harvey threatens to leave people behind (Rice Kinder Institute): Almost half of people from Harris County that responded to an Episcopal Health Foundation and Kaiser Family Foundation survey lost income from Harvey. Seventeen percent of people from 24 counties surveyed are now suffering a new or worsening health condition. Harvey’s damage has stretched people and resources thin and has led to cascading impacts that will continue to be felt in the region and threatens to leave vulnerable and lower-income populations behind.

Where do we go from here? Houston-area leaders grapple with Harvey aftermath (Houston Chronicle): The Houston Chronicle held a symposium last week to discuss Houston after Harvey. Here are some highlights from that event.

Post-Harvey week in review: December 4, 2017

We’re back with another Monday wrap-up of the last week’s stories about Houston’s recovery from Harvey and flooding issues in our region. Feel free to share any that we missed in the comments. If you missed the last two weeks of recaps, you can find them here:

Reads of the week

Early results of federal rainfall study show dramatic growth in 100-year storm (Houston Chronicle): An initial study from NOAA (currently in the peer review process) suggests that the rainfall of a 100-year storm in Harris County (a storm that has a 1% chance of occurring in any given year) has increased by 3-5″ since 2001. If that holds up, that has enormous implications on development and how we define floodplains in the Houston area.

Furthering the point that all this is very preliminary, Jeff Lindner of Harris County Flood Control points out that there are still some questions about the gage data and methodology that was used.

This will be an important story to follow in the months ahead.

Developers Said Their Homes Were Out of a Flood Zone. Then Harvey Came. (New York Times): At least 6,000 properties in locations that were redesignated after previously being classified as in flood zones ended up with damage from flooding during Harvey. Map changes are legal and come via raised lots, levees, drainage systems, water-detention ponds, etc. But the margin for error is small, and not all property owners realized this. A provocative story with a focus on The Woodlands.
