In brief: Houston’s pattern will continue to bring a chance of daily showers. For the next two days, in particular, much of the region should see rain and a bit cooler temperatures. We should get back into the mid-90s later this week, and into the weekend. So basically, it will feel like July in July.
A year since Beryl
Conditions are quite a bit nicer this morning than they were one year ago today, when Hurricane Beryl made landfall down the coast from Houston. At this time we were seeing maximum winds across the region, with gusts above hurricane force strength affecting much of the area. This caused significant tree damage and knocked power out to millions in the region. So it is not a particularly happy memory for most of us.

Tuesday
A couple of factors will support ongoing, healthy rain chances across the Houston region this week. These conditions, the combination of lower pressure and lots of moisture in the atmosphere, should be especially pronounced today and Wednesday. As a result we should see the development of fairly widespread showers and thunderstorms.
As usual, these showers will be hit or miss. They will start out closer to the coast later this morning, and then spread inland throughout the afternoon and early evening before waning after sunset. Some locations may pick up 1 inch of rain under stronger storms, whereas as other locations will only see light rain or dark skies. You’ve seen this story before in Houston. Most locations, on average, should pick up a few tenths of an inch of rain by the end of Wednesday.

Partly to mostly cloudy skies this afternoon, in addition to rain-cooled air, should help to limit high temperatures to the lower 90s. Winds, generally, will be light at 5 to 10 mph except within stronger thunderstorms. Lows tonight will drop into the mid-70s for most locations.
Wednesday
This will be a similar day to Tuesday, with rain chances above 50 percent. Again we can expect a few thunderstorms, but mostly I think these will be light to moderate showers. Highs, again, will be in the lower 90s.
Thursday and Friday
The second half of the week should bring somewhat lower rain chances, but they still should be somewhere in the 30 to 50 percent range. Accumulations will be less for most locations. Accordingly, daytime highs will be a little bit warmer, in the mid-90s for most locations. This is plenty hot, but also pretty much par for the course in mid-July.
Saturday and Sunday
Unfortunately I still do not have a great handle on the outlook for this weekend. It depends on the extent to which high pressure can build up over the area, and there is no agreement in the various models I am looking at. My sense is that we’ll see highs in the mid-90s, with a decent (i.e. maybe 30 percent) chance of light to moderate showers each day. Hopefully in another day, or so, the forecast will come into better focus.

Next week
Overall next week looks a little bit warmer, with high temperatures in the mid-90s, and possibly some areas sneaking into the upper 90s. I think rain chances may step back a little bit, compared to this week at least, but I’m not sure the spigot will be entirely shut off. Basically, July will continue to do July things, probably.
