We anticipated some rain, some hail, and damaging winds on Wednesday afternoon and evening in the Houston region, but we did not quite expect what we got. The primary damage came from strong wind gusts of 65mph or higher, which knocked down fences, and trees into power lines and structures. At one point more than 275,000 CenterPoint customers were without power. We expect one more shot of rain and storms today, although not quite as significant, before our weather calms down heading into the weekend.
Unfortunately the setup today is similar to Wednesday, in terms of the overall pattern, but should be less intense. We expect generally sedate—and rather pleasant, for late May—weather this morning. However daytime heating will help generate the threat of strong thunderstorms later today, with the threats of wind and hail. Rainfall accumulations should be less for most people, as should areal coverage. Hard to say where the biggest threat lies, but most of the models are suggesting it will be closer to the coast than far inland today. Highs will be in the upper 80s, with sunshine this morning before clouds develop later today.

A weak front should arrive sometime on Friday morning, bringing with it an end to rain chances. This will usher in something of a drier air mass heading into the weekend, and we should see clearing skies throughout the day. Highs will likely reach 90 degrees.

Storms have exploded northwest of Houston today with numerous reports of large hail, up to as big as golf ball size or larger. As I write, this large hail is possible near Bryan in the Brazos Valley.

As a result of this, a Severe Thunderstorm Watch has been hoisted for the entire Houston area through 9 PM this evening. The main threat will be between now and 6 PM I think, however. These storms near Bryan-College Station are hauling south and east around 20 to 30 mph, and new storms are trying to blossom out ahead of them.
The main threat from today’s storms is likely to be large hail. Not everyone will see hail, but those that do (most likely along and north of I-10) could see hail to the size of golf balls or even a little larger. The hail threat today is legitimate. A secondary threat will be strong winds, capable of knocking down trees or power lines in spots. A very small tornado threat is there, but it’s not especially high at this time. We’re focused on hail and wind today I think. Heavy rain is also possible from any of these storms.
While the severe threat should fizzle after sunset, we may see additional rounds of showers or even some thunderstorms into later this evening. We’ll update again if things look more significant. But please stay weather aware through this afternoon and evening.

Good morning. The Houston area is sailing toward fairer weather—this weekend looks hot and sunny—but before that time we’ll face a couple of days with fairly healthy rain and thunderstorm chances. Also, with the school year ending, Matt and I will be convening our final Wednesday Weather discussion on Facebook at 10am CT today. Please join us. I’ll post a link to a YouTube version tomorrow morning if Facebook is not your thing.
Conditions this morning are quite fine for late May, with clear skies and temperatures lower than normal. Conroe got down to a spectacular 60 degrees with the region’s slightly drier air. However the sunshine is unlikely to last for most of Houston. Even though an upper-level level low pressure system is moving away from us, it should help pull an atmospheric disturbance into the area. What we think probably will happen is the development of storms west or northwest of Houston sometime this afternoon.

These storms will then sag and then (maybe?) weaken as the slide into the city during the late afternoon, evening, and overnight hours. NOAA’s severe weather outlook shows the higher risk to the west of Houston, with the threat of strong winds and hail. Rain accumulations will be less than half an inch for most, but areas under heavy thunderstorms will get more. Until storms develop today expect mostly sunny skies with highs near 90 degrees.
A similar pattern could set up Thursday, with partly sunny skies in the morning giving way to the potential for storm development during the afternoon. This may be aided by the passage of a weak front—hard to call it a cold front as there won’t be much cooler air. Rain chances are around 50 percent for the region, with highs again going up to around 90 degrees.

Good morning. Moderate to briefly heavy rainfall moved through the Houston area during the overnight hours, generally dropping between 0.25 and 1 inch of rain. This looks to be the last of our organized storm systems for awhile, although our region will certainly face the possibility of scattered showers and thunderstorms this week. But overall, the last week of May 2020 will be reasonably pleasant weather-wise, with slightly lower humidity than normal. Enjoy this, friends, because June is around the corner.
The remnants of the overnight rainfall system are pushing through Houston this morning, and should move out by 8 a.m. or 9 a.m. Skies should be partly to mostly cloudy today, with the possibility of additional scattered showers this afternoon. Highs will reach the mid-80s. You may notice winds start to come from the north later today, and this will give us shot of slightly drier air that may linger for most of this week. It should be especially noticeable this evening, and on Wednesday morning when lows drop into the 60s for most areas except the coast.

The much discussed upper-level low pressure system should continue to wobble away from the region on Wednesday, and this should lead to partly to mostly sunny skies. This, in turn should allow for temperatures to push into the upper 80s, and this daytime heating may trigger a few afternoon showers. Lows Wednesday night should be a few degrees warmer than Tuesday. It’s possible we may see some additional showers late Wednesday night into Thursday morning, but I don’t have overly high confidence in this.
