Our official morning low at IAH Airport was 57° yesterday and 58° today, the coolest pair of back to back days since late April or early May. We are now on the “other side” of things in the wake of the cold front, which means that, while it will still be quite nice the next couple days, it will begin to warm up a bit.
Today & Saturday
Both days look mainly sunny with light winds and comfortable humidity. Look for highs in the mid-80s and nighttime lows inching back into the lower or middle 60s.
As high pressure gradually slips to our east, we will see onshore winds gradually return here, which means humidity will inch back up just a bit also by tomorrow.
The end of the weekend will mark the true transition back to more late-summer weather. Expect continued sunshine and a morning low in the mid-60s (warmer at the coast), followed back daytime highs in the mid to upper-80s with a bit more humidity.
Monday & Tuesday
Weather models had been pretty aggressive with bringing rain back to the area next week. For Monday and Tuesday at least, that doesn’t seem too likely. Yes, there will be shower chances on both days, but the setup initially looks kind of mediocre, with probably just a few showers and generally lighter rainfall totals by the end of Tuesday. We will see clouds and plenty of humidity though. Look for highs near 90 degrees and lows in the 70s.
Wednesday & Thursday
The middle to late part of the week may see just a little more support for showers, so rainfall could be a bit more noticeable then. Highs will be contingent on cloud cover and could exceed 90 with enough sunshine, but we’ll generally call for upper-80s or a little cooler with more rain showers.
Overall, we aren’t especially excited about this setup for rain next week. Given the models maybe backing down some today, it looks like an average of 1 to 2 inches is most likely across the region. The highest amounts may be south and west of Houston. Some of you may see less than an inch too. More on this for you Monday.
Late next week
Weather models have been at least hinting at some kind of cold frontal passage later next week for a few days now. It’s too early to get too specific, but I think the evidence points to a couple things right now. First, the “front” will probably not be like this week’s front in that we aren’t going to turn significantly cooler behind it but rather a little cooler but a good bit less humid. I wouldn’t expect 50s for lows right now, but we’ll see.
Second, the timing of the front would be probably next Saturday or Sunday, so most, if not all of next week looks humid. Could all this change? Certainly. We’ll see how things go over the next few days and report back to you next week on what’s happening. So, soak up the next day or two if you like autumn weather.
I want to just append a quick note on the tropics today because yesterday morning we had Tropical Depression 18. This morning we have Hurricane Sam. Sam has rapidly intensified into a hurricane out in the open Atlantic.
Sam is expected to become at least a strong Category 3 storm over the next few days which will also help it probably track a little more to the north than it appeared a couple days ago. This should hopefully bypass the Caribbean islands entirely and then turn north and out to sea, though Bermuda may need to keep an eye on Sam. Otherwise, as Eric noted yesterday, at least the Gulf should remain trouble-free.
Have a great weekend!
