After Tuesday’s stellar weather, conditions will turn a little bit warmer before a cold front sweeps into the area toward the end of the week. The big question remains when this will happen—anywhere from early to late Friday—and this timing will help determine how wet things get in Houston.
Wednesday
Most of the region is starting out this morning somewhere in the neighborhood of 60 degrees. An east wind will turn southeasterly later today, allowing for the onshore flow to resume. Winds could become a bit gusty this afternoon. All in all, however, this still should be a pretty nice fall day with high temperatures tickling 80 degrees and mostly sunny skies. Lows tonight should fall into the mid-60s for central Houston, a bit warmer to the north, and a bit cooler to the south.

Thursday
This should be a more cloudy affair, as moisture begins to stream inland. This will augur the potential for some heavier rain, but for now this appears unlikely before sunset, and most likely after midnight. Highs Thursday will be in the low 80s, with ample humidity, and lows Thursday night probably won’t drop much below 70 degrees.
Note: We’re big fans of the Capital Weather Gang site in Washington D.C. So to mark the beginning of the World Series between the Astros and Nationals, we have agreed to publish their best attempt to trash talk Houston’s weather. In turn, Matt and I got to set the record straight on their site about catastrophe that is Washington’s bullpen, err, weather. Here, then, is why Houston’s weather allegedly sucks.
Houston: You have a weather problem. From hurricanes, to 500-year floods, and the relentless heat, I am not sure how you stand it. Washington’s weather is clearly superior.
We Washingtonians like to whine about our hellish heat and humidity, which occupies about two months of summer here, from roughly mid-June to mid-August. In your city, it starts to feel gross outside starting in April or May and doesn’t abate until around now.
Let’s examine this year, for example. You’ve already posted 10 days with highs in the 90s and lows in the 70s in October. You’re running your air conditioners full blast when you should be outside in the crisp autumn air picking apples and pumpkins while watching the leaves change.

Seasons are something you know little about. You have six months of summer and six months of “meh.” Fortunately, you’re about to enter “meh” when you’ll finally be able to step outside again without sweating through your clothes.
As your average high temperatures fall through the 70s and 60s, you’ll be able to boast about some nice days between November and April. But, frankly, these days have little to offer. It will neither be warm enough to be out at the pool nor cold enough to enjoy winter activities like skiing and sledding, sadly foreign to you.
For anyone who likes snow, your city is a nightmare. It’s cute in a pathetic sort of way that a local news organization writes “Snow in Houston happens more than you think” when measurable snow has fallen at Houston Hobby airport just 10 times in the last 89 years, the most being 4.4 inches on Feb. 12, 1960.
Washington isn’t exactly a snow town, but it averages about as much of the white stuff in one winter as you’ve seen since 1930. (Yes, we are aware that 20 inches fell in your city in 1895 during a single storm and, props, that was impressive.)
Now let’s talk about rain. I need to be sensitive here because I feel for the folks who have been flooded repeatedly over the past few years. But the deluges you’ve dealt with are perhaps the most challenging and unsettling aspect of Houston’s climate.
You’re probably painfully aware that five exceptional rain events have inundated your region in the last five years, some of them, like Harvey and Imelda, considered 500-year rainstorms.
It is true that Washington can be rather soggy, and 2018 was our wettest year on record. But the rain we see is but a sprinkle compared to the tropical torrents in your city. Unlike Houston, which can get hit by hurricanes head-on, the tropical storms affecting Washington are typically weaker since they first pass over tens of miles of land.
For having four real seasons and for our tamer breed of heat and rain storms, we’ve got you beat in the weather department, Houston. Trust that our winning ways will carry over to this week’s World Series.

Good morning. We hope everyone enjoys today’s absolutely stunning weather, from a cool morning through a pleasant, sunny day, and clear skies this evening. We’ll have more of the same on Wednesday before confidence in the forecast plummets heading into the weekend. Let’s discuss why below.
Tuesday
As mentioned, today will be a grand affair, with sunny skies and high temperatures around 80 degrees. With dry air, lows on Tuesday night will cool down to about the same temperature as on Monday night.

Wednesday
As high pressure moves off to the east on Wednesday, the region will begin to open up to an onshore flow from the Gulf of Mexico. But daytime conditions will still be quite pleasant, with sunny skies and highs around 80 degrees again. Wednesday night lows should get into the 60s for all but the immediate coast.
Thursday and Friday
And here, the divergence begins. The forecast models are struggling with how to handle the evolution of a large area of low pressure over the southwestern United States. One camp of models, led by the GFS model, brings this system eastward pretty quickly, and drives a strong cold front into Houston on Friday. Under this scenario, we may see a smattering of rain as the front blows through, with much colder weather afterward. The second camp of models, led by the European forecast model, holds up the front, allowing a surge of tropical moisture to push into Texas on Friday and Saturday. Under this scenario, Friday is rainy and muggy.
The high temperature on both Saturday and Sunday topped out at 90 degrees at Bush Intercontinental Airport, making for a warm weekend. If you’re tired of Houston’s long, long summer—the region had its first 90-degree day back on April 9 of this year—the good news is that we’re probably done with 90-degree days for 2019. In fact, we should mostly be in the 70s for this coming week and weekend.
Monday
A line of storms will push through Houston at around sunrise, or a little before, on Monday morning. A few of these storms are fairly strong, but the line is moving from northwest to southeast fairly quickly, so we don’t have any flooding concerns. Most areas should see about one inch of rain. Unfortunately the storms will hit during the morning commute for some people. The front should be off the coast by or before noon. In the wake of the front, highs today should hold in the 70s, with most of Houston falling into the upper 50s on Monday night with clearing skies.

Tuesday and Wednesday
These will be a pair of gorgeous days, with cool mornings in the upper 50s (except along the coast), mostly sunny skies, and highs in the upper 70s to possibly 80 degrees. An onshore flow resumes on Wednesday night, which should nudge lows into the mid-60s.
