High pressure dominates Houston’s weather this week, which means heat and humidity

The weather this week is fairly straightforward, so we won’t be wasting too much of your time or ours. High pressure is building over the area and it will hold sway through the work week. Temperatures should peak by Friday or Saturday, perhaps in the triple digits, before some slight relief potentially arrives later this weekend. We are near the point of the longest days of summer, so you should absolutely be protecting your skin from prolonged sun exposure and taking heat relief measures.

Monday

Highs today will be in the low 90s, with mostly sunny skies. Rain chances are near zero, and the biggest difference from Sunday will be that winds out of the south become a little more pronounced, blowing at 10 to 15 mph, with gusts up to around 25 mph. Lows on Monday night will be in the upper 70s.

Tuesday

Wednesday, Thursday, and Friday

The heat starts to peak during the second half of the week as the ridge intensifies. High temperatures will push into the mid- to upper-90s across the region away from the immediate coast. Some areas have a chance of hitting 100 degrees by Friday or Saturday. TL;DR: Hot, hot, hot.

Saturday and Sunday

The first half of the weekend should bring more of the same, in terms of heat and sunshine. But later on Saturday a weak system may move in from the north to bring some cloud cover, a slight reduction in temperatures, and some slight rain chances. I’d pencil this in for now, however, as this dying cool front may well wash out before reaching Houston.

Tropics

After crossing Florida this past weekend, a tropical system got better organized and developed into Tropical Storm Alex on Sunday. It will pass just north of Bermuda as it moves out to sea and eventually dies. Beyond Alex, there is not really anything to see. A tropical disturbance may spin up in the southern Gulf of Mexico in 7 to 10 days, but for now it’s not something I anticipate affecting Texas weather in any way.
