Month: September 2016

The much-discussed first front of the fall season has pushed off the coast and into the Gulf of Mexico, but drier (and cooler) air has largely lagged behind. As we suggested on Monday, it will be a slow process, but much more fall-like weather is still on the way.

Very heavy rains have fallen over night along the I-35 corridor of Texas, with a focus on Bexar County. Up to 7 inches have fallen in the metro area there. If you are traveling toward the San Antonio area today please take care due to flash flooding occurring across the city. As the front slowly moves into the Houston region today we should see our rain chances pick up, but I do not expect more than 1 to 2 inches of rain for most of the Houston region.

Today

As the front trudges toward Houston we should see an increase in coverage of storms across Houston, especially to the west and north of the city. Highs will be in the mid-80s and I’d expect coverage similar to Sunday, with intermittent heavy rains that might cause some temporary street flooding, but nothing too extreme. The front itself should move through central Houston tonight.

Tuesday

Although the front will probably slog into Houston and off the coast by Tuesday morning, it will take some time for the area see the effects of cooler and drier air. As a result some showers and thunderstorms will remain possible on Tuesday morning, and highs will be possible in the mid- to upper-80s.

We can now say with increasing confidence that some sort of cool front is coming to Houston, but it does not appear to be a classic, blow-in-from-the-northwest type of system that will knock down humidity and temperatures within the span of a few hours. Rather, drier and eventually cooler air should move into the area rather slowly, over a period from Monday to Wednesday. But something is better than nothing!

Today

Scattered showers over the Gulf of Mexico this morning should migrate in later today, with periods of sunshine and clouds, and scattered showers. Still warm and muggy, with highs near 90 degrees and lows in the mid-70s.

Sunday and Monday

Rain chances will be higher on Sunday and Monday, as moisture pools ahead of the front. Can see most of the area getting between 0.5 and 1.5 inches, with the potential for greater amounts in isolated areas. The “front” might move into central Texas on Sunday night, and will approach the western fringes of the Houston metro area sometime on Monday, probably during the morning. However it is unlikely that much of Houston will see drier air until late Monday at the earliest.

Tuesday

As some drier air moves in rain chances should fall, although probably won’t go away entirely. Highs will likely be in the upper 80s. Lows may be anywhere from the low 60s to the west of Houston to the upper 70s near the coast.

Wednesday through Friday

At this point drier air should finally work its way more fully into the area, bringing us mostly sunny skies. I don’t think the global forecast models have a great handle of temperatures yet, but it seems likely we’ll see highs in the 80s (low or high, not clear), and lows in the 60s (again, could be low or high). Although it won’t be cold, the cooler, drier evenings and mornings should nonetheless feel great. And once the first front comes through, it’s easier to get the second one.

Autumn is often a time for weather forecast headaches. We’re wasting no time this season, with our first legitimate cold front of the season knocking on the door next week, though there’s a good chance the door won’t open. Let’s talk details.

Today & Saturday

First, the “easy” part of the forecast. Summer-lite continues the next couple days. We’ll see some showers and perhaps some thunderstorms off the Gulf each morning and afternoon. These will be of the typical Southeast Texas scattered and hit/miss variety. If you have outdoor plans the next couple evenings, go ahead with them, but just know there may be a downpour or two to contend with.

Heading to the Dynamo match, Rice game, or Astros game? Maybe a downpour, but not terrible.

Temperatures will remain on the warmer side. Expect highs near 90 or in the low 90s. Overnight lows will remain miserably warm, in the mid to upper 70s inland to near 80 at the coast. Read More…

Good morning. The cold front watch continues for Houston, but alas there’s still no certainty about what lies ahead. One thing we can have some confidence in is a return to a more rainy, unsettled pattern this weekend.

Today

With some moisture returning to the area we can expect to see some isolated to scattered showers later today, along with still very warm temperatures in the low 90s. Very summer-like.

Friday and Saturday

More moisture will flow in off the Gulf of Mexico, and at the same time the ridge of high pressure that pushed temperatures up this week is going to move off, opening up the possibility of more widespread showers and thunderstorms. I’m not expecting anything too intense, and most areas will probably see a few tenths of an inch of rain, or less. Highs will be around 90 degrees, under partly sunny skies, with lows in the upper 70s.

Sunday and Monday

A large trough of low pressure, along with a cold front at the surface, is going to move into Texas on Sunday (west Texas) and Monday (most of the rest of the state). With moisture still flowing into the state from the Gulf of Mexico, this front could generate a lot of rain—perhaps as much as 10 inches for some areas along the I-35 corridor (heads up, Dallas), or just to the west of it.
