Texas sizzles onward

We had a few showers again on Wednesday, but nothing too exciting by Southeast Texas standards. We may do it once again today, but heat will be the main story.

In case you missed it, Braniff Davis was back with another “Weather Whys” post last evening, discussing the sea breeze and the Gulf of Mexico and how they influence our weather. Check it out here.

TODAY AND FRIDAY

No big changes in the weather for the next couple days. I still expect it to be hot and humid both days, and I still anticipate we will see at least a couple showers blossom on radar each day. Exactly where they go and how widespread they’ll be is up for debate. A weak disturbance rotating around the Plains heat dome will probably set off more organized, but scattered storms in western Louisiana today. I doubt these make it to Houston, but if you live east of the city (particularly, if you live closer to Beaumont/Port Arthur), you may get a downpour later this afternoon. We may try and repeat this on Friday with another disturbance, perhaps getting a bit closer to Houston. High temperatures should again aim for the mid to upper 90s both days (hottest inland, cooler at the coast).

Houston’s summer marches on

Houston’s weather has been a bit noisy this week. After another busy day Tuesday (a bit surprising to me admittedly), today should see the volume turn down a bit. Showers and storms moving through the region dumped 1-2″ on some folks, while others, again, saw nothing but some clouds. Again, welcome to Houston in summer.

Speaking of, this evening, Braniff is going to have more on some of the “why” behind our summertime storms!

TODAY

Given the action of the last few days, I feel obligated to at least include a chance of showers and a thunderstorm today. That said, weather radar is much less active this morning than it has been the last couple days. The weather models also insist that activity will be less than yesterday. This does have merit, as the heat dome over the Plains has expanded in the last 24 hours, meaning slightly drier air should be taking hold.

Still, it would be wise to be cautious with the forecast today. We’ll say, “Probably not many showers, but there should still be a few around.”

Temperatures begin their upward march though: Back into the solid mid 90s today.

Rain to exit Houston, plus a tropical checkup

Yesterday was certainly fun, wasn’t it? A substantial chunk of our audience saw some pretty strong storms, but rain totals were very sparse. The axis from Pasadena through the Heights saw 1-3″ of rain, but many areas around city heard thunder and saw no rain. Such is the nature of summertime storms in Houston.

TODAY

We’re already starting off today with a somewhat active radar, as scattered showers reach the coast from about Sabine Pass down through Matagorda Bay. Showers will be around this morning. As we go through the day, I think the best chance of rain will shift south and west of Houston. The further north and east you go from the city, the less storms you’ll see by afternoon (though not quite zero). Temperatures should again try for the mid 90s.

Houston’s rain chances soon to slip away

After a mostly quiet weekend around Houston, we had some excitement Sunday. In the morning, we had a waterspout in Galveston that prompted a Tornado Warning. Then, we saw numerous showers and storms around the area in the afternoon.

Rain totals weren’t terribly impressive, but a couple spots saw up around an inch of rain.

Anyway, as we go into this week, we’ll start with rain chances similar to what we saw yesterday.


MONDAY & TUESDAY

With a good onshore flow and a surge of good moisture, it will be wise to keep rain chances in the forecast for Monday. Like yesterday, this won’t end up being a widespread soaker, but some of us will see some beneficial showers, downpours, and possibly thunderstorms both this morning and this afternoon. Outside of that, continued sticky and hot, with highs in the low to mid 90s.

I think tomorrow will be a similar story, except we begin to see high pressure flex from the north. That means the best rain chances will be south of I-10. But again, a modest amount of shower/storm coverage should be expected. Again, highs should be in the low to mid 90s, with mid to upper 90s north of the Houston metro area.
