In brief: In today’s post we discuss the onset of truly summer-like humidity and the expectation of three more warm and mostly sunny days. Rain chances return Sunday, and we expect widespread showers on Monday and Tuesday of next week.
Solidly summer-like humidity
Dewpoints across the Houston region have reached the mid-70s of late, and this is pretty much our typical level during summer in Houston. If you wonder why it feels so muggy outside, it is because of this. We basically reach a point during the year when dewpoints never fall below this level, day or night. We’ve not had the full summertime-in-Houston experience yet, with blistering hot temperatures such as highs reaching the upper 90s. And fortunately that does not appear to be in the cards for at least another week or two. But deep summer humidity is here, and likely will not relent until September.
Thursday, Friday, and Saturday
I’ve lumped the next three days together because there really won’t be much sensible change in our weather from day to day as high pressure reigns. We can expect to see high temperatures ranging from the upper 80s near the coast to the lower 90s for inland areas. Skies should be mostly sunny during the daytime with afternoon winds gusting up to 20 mph. Nights will remain warm and sultry, with lows only briefly dipping below 80 degrees. Each day will have a 10 to 20 percent chance of a brief, passing shower but for most of us our days will remain rain-free.
Sunday
This will be a bit of a transition day. I still expect highs in the low 90s for most of Houston, but as high pressure retreats southward we could see some increasing rain chances during the afternoon or evening hours. I don’t expect any kind of a washout, but this could be a nuisance if you have outdoor plans later on Sunday, including after the opening World Cup game in Houston that afternoon.
Next week
The combination of high atmospheric moisture levels and an approaching front (don’t get your hopes up regarding significantly cooler or drier air) will increase rain chances beginning Sunday evening through next Tuesday or so. In terms of accumulation I expect much of the region to see something like 2 to 4 inches of rain during this period, and the rain-cooled air could bring down afternoon temperatures into the mid- to upper-80s. We’re going to be monitoring things for flooding potential, but as of now I think conditions will be mostly manageable. By Wednesday, and the rest of next week, we likely will be back into a pattern of highs around 90 degrees and perhaps a 30 percent chance of afternoon showers.
