After a few days off, unsettled weather returned on Thursday, bringing some folks over three inches of rain. Others saw nothing at all, but everyone is likely in line to see at least some rain over the next couple days.
Radar isn’t too active this morning with a few scattered showers — mostly light or occasionally moderate rain.
As we go into the rest of today, look for scattered downpours and thunderstorms to blossom from later this morning into this afternoon. Like yesterday, we could see locally heavy rainfall in the most persistent storms. Rain amounts will again vary wildly, with some folks seeing little to no rain, while others could see two to four inches in a relatively short time, along with some localized street flooding.
Saturday & Sunday
Unfortunately, the specifics surrounding the forecast this weekend are going to be difficult to lay out. If you’ve lived in Southeast Texas for any length of time, you know that our rain often follows a pattern of feast or famine: Neighborhoods that get soaked may be adjacent to dry neighborhoods. Trying to predict where and when it’s going to rain this weekend is impossible to do more than a few hours in advance, but we know that both Saturday and Sunday carry high chances that it will rain for a period of time during the morning or afternoon hours.
Total rainfall should add up to about an inch to two inches on average across the region by Sunday evening. Some folks will see less than that. Others may see three, four, or five inches of rain or even a little more with some street flooding. If you have outdoor plans this weekend, include an umbrella and an indoor backup if possible. Where the heaviest ultimately falls will depend on how far south a cold front can push, along with other small-scale processes in the atmosphere.
If there’s good news in all this, it’s that our six day string of 90°+ weather should end. We’ll see high temperatures in the mid-80s, with lows in the mid-70s. Yes, it will be unpleasantly humid, but at least it won’t be obscenely hot for later September.
There are two questions I am anticipating we see rev up over the next week from our readers. 1.) Is hurricane season over for us? And 2.) When is autumn weather coming?
Starting with the second question, you’ve seen Eric write or either of us tweet about this potential cold front later next week. Before we get there, we’ve got several more days of warm, muggy, and unsettled weather to get through. The forecast from Monday through Wednesday looks pretty similar each day right now. Expect clouds and some sun, with scattered to numerous showers and thunderstorms each day, beginning near the coast in the morning and spreading inland during the afternoon. We will do mid- to upper-80s for highs and mid-70s for lows.
Unfortunately, the first opportunity at a cold front getting through here late next week is fading. Modeling has backed down on this risk
Models suggest the front is going to get hung up in Oklahoma or North Texas next week, keeping us warm and humid with unsettled weather in South Texas. I do still think we will get a front through here soon, but we may have wait another few days for a chance around October 2nd. Patience is required this time of year.
Eric touched briefly on the tropics yesterday, and not much has changed today. For our purposes, it remains quiet. Across the Atlantic it’s beginning to shows signs of becoming more active again, but none of these systems pose any credible risk to us and the ceiling on how strong these systems become looks pretty low at this time.
The main thing Eric and I will be monitoring is in the Caribbean. If we look at the modeling, it’s generally showing an increasing risk that something tries to develop in the southwest Caribbean in a little less than two weeks. That’s a climatologically favored area for tropical development in October. Usually, systems develop there and lift north toward Florida or the Bahamas. In this case, we don’t see any reason to think that won’t be what ends up happening. But, of course, if you’ll recall Hurricane Nate last October formed in that area and ultimately moved ashore in Mississippi, which is a little further west than usual.
A quick history lesson: Texas has had seven tropical systems make landfall or pass nearby in October since the 1850s. That’s not many. The last was Hurricane Jerry in 1989. Prior to that, we had gone 50 years without one in October. But they’ve all originated in that general southwest Caribbean or Central America area. So while no reliable weather model shows anything of concern for us at this point, we’re keeping a passing glance on it, just to be safe. We’re very close to the finish line for our hurricane season in Texas, so we just want to make sure there are no last second stumbles.
