In the absence of high pressure, widespread showers likely today and Wednesday

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.

Values of precipitable water, the amount of moisture in the atmosphere, of 2 inches and above are a good indication of rain. (Weather Bell)

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.

    I would not exactly call this the “year without a summer” but it’s been very normal up to this point. If you are doing the math it’s been 320 days since our last triple digit reading at IAH. That’s a good thing.

    • So true. While this summer is still averaging above normal, it has still been a walk in the park compared to the brutality of the summers of 2022 and 2023.

  2. My wife and I chose our wedding date, July 8, because we thought there was a lower chance of a hurricane impacting the day. We have lots of teachers in our family, so we wanted a summer wedding. A/C exists, plus we got a nice venue discount for choosing a summer date.

    Thankfully, we were right about hurricanes when we got married in 2023. We were in Seattle on our first anniversary as the eye of Beryl passed over our home. Phew.

  3. I wonder what is the lowest mean temperature for Houston in June and how this past June ranks? We’ve had a nice (in Houston terms) summer so far it seems, aside from skeeters.

    • Artificial Intelligence quotes the Greater Houston Partnership. This is most likely not the information you are looking for. In June, the average high temperature in Houston is 91° Fahrenheit and the average low temperature in Houston is 72° F.

    • The coolest June on record for Houston was in 1919 with a mean temperature of 77.5. This year was actually the 10th warmest June on record for Houston with a mean of 84.7.

      While this past June was realitively temperate compared to some of our recent June’s, it was still well above normal when compared to the historical average.

    It’s July. Temperatures are normally warmer than normal in July.

  5. If we had Beryl in her prime, we would still hear the sound of hammering nails and sawing wood to replace rafters today.

    • Facts. There would still be people without a home sadly enough. We were very lucky that Beryl’s development was being suppressed by that plume of dry air that intercepted its circulation in the Gulf or it would have been much worse.

    • There are still people suffering from Beryl. Roofs all over the city were weakened & damaged. Then the lack of electricity. Breeding ground for mold that’s still going on now. Silent spread of toxicity.

      🙁
