Good morning. Thanks to Eric for covering me the last few Fridays as I took some time to step away from weather forecasts and explore Utah, which is an absolutely incredible place. And there was snow, for real! Anyway, it’s good to be back in Houston, and it would be better if the Astros were to win tonight. Let’s do some weather, as it is an active, changeable period the next several days.

Today

An area of heavy rainfall formed overnight southeast of Houston dumping nearly 7″ of rain (including 4.5″ in an hour) near Friendswood along Clear Creek.

The heaviest rain has shifted north, but Clear Creek may still rise a bit close to bankfull in spots but not out of banks. Street flooding is likely to continue a bit longer this morning in this area.

 

So what does the rest of today bring? We’ll probably see continued periods of rain and thunderstorms east of Houston south to near Galveston. Rain will come in spurts, but it could be heavy at times. I think the heaviest will be east of where the serious rain was earlier this morning, and the rain should be intermittent enough in places like Friendswood, Dickinson, and League City to not cause any further serious problems. That said, there may be some pockets of street flooding issues in parts of Chambers or Liberty Counties today, but they’ll probably be isolated.  Elsewhere, keep an umbrella at the ready. Expect isolated to scattered showers and storms in the area, especially through early afternoon.

Temperatures will be held back a bit with clouds, but since we’re starting much warmer than yesterday, we should crack the lower 80s this afternoon (a few places west of the city may do middle 80s). We may see a few showers around this evening or overnight, but far less coverage and intensity than this morning. Most of us will stay dry tonight.

Quick note: Many of you have reached out to us looking for book recommendations about weather. Well, we listened. Look for a post later this morning that has a handful of recommendations we hope you enjoy.

On to the weather. After some scattered showers and storms on Thursday, things will begin to calm down today, setting up a warm but pleasant weekend. A couple interesting notes about rainfall, courtesy of the NWS Houston office: First, officially, it’s the third wettest year on record (back to 1889) already for Houston. We only need 0.82″ of rain between now and New Year’s Eve to set a new record for wettest year in Houston. On the flip side, if Galveston manages to not receive 0.03″ of rain before tomorrow night, they’ll set a new record for driest September on record (back to 1872). It’s been a weird year.

Weekend

So we’ll keep mentioning a chance of a shower or thunderstorm today, but I think most of us will stay dry. Precipitable water, which is a good measure of how much moisture is available in the atmosphere, will drop off through the day today as we advect in drier air.

In English, that means chances of showers and thunderstorms should diminish today. It will not quite get to zero south of I-10, and I think the majority of us will stay dry. We’ll gradually usher in even drier air tonight, leading to comfortable dewpoints and low humidity on Saturday and completely shutting off rain chances. The weekend should be dry for the entire region.

Though the humidity will lower, the temperatures will stay relatively warm for the turn of the calendar to October, and we should see continued high temperatures in the upper 80s, with morning lows in the slightly more pleasant upper 60s.

As Eric described yesterday, this weekend’s front is not packing much punch with it. I mean, look, a break from the high humidity is definitely nice, but we would all probably prefer something more definitive by now. “Autumn” is fickle in Texas.

Today & Friday

More of the same is expected. Portions of south-central Texas have received over 10″ of rain this week, and there’s currently flooding on the Rio Grande near Laredo. We’ve been far enough east to really avoid most of it, and we’ll remain there again today. Just a smattering of hit or miss downpours should be expected today. It will probably be a bit more than the last two days with the front approaching. Otherwise it will be partly sunny and continued hot and humid.

The front should work through here either late today or early Friday. You probably won’t notice much of anything though until Friday night. So expect another warm to hot day Friday, with a good bit of humidity. Perhaps it won’t feel as oppressive as Thursday. We’ll continue with a very slight shower chance Friday before the drier air arrives Friday night.

Weekend

All in all, this weekend should be a decent one. We’ll certainly have lower humidity on Saturday. In fact, if you watch the animation below, you can see how the dewpoints start to drop off Friday night into Saturday morning. That will lead to a really nice, albeit still hot Saturday.

Sunday will be similar, with a good deal of sunshine, but humidity staying under control. Both days will see high temperatures generally in the upper 80s (perhaps a couple degrees cooler north). Morning lows will bottom out in the upper 60s in Houston proper, but cooler in some of the suburbs. I don’t know if it will feel “refreshing” per se, but it will be nice for a change.
