Just a quick update this evening to call attention to a large complex of thunderstorms slowly moving across northwestern Harris County, Waller County, and southwestern Montgomery County. Here, unstable air is combining with tropical moisture to produce very heavy rainfall.

The National Weather Service has issued a flood advisory through 1:30am CT on Tuesday morning, and some areas could see 3 to 5 inches of total rainfall from late Monday through early Tuesday. These rains could cause street flooding and potentially threaten some structures in low-lying areas. The primary concern is that as this system gets closer to the coast, and more tropical moisture, the storms could continue to strengthen.

In terms of motion, the storms seem to be slowly sagging southeastward, and may move deeper into Harris County tonight, possibly toward the central part of the Houston region.

Houston will remain under the influence of a moist air mass during the next couple of days, which will lead to intermittent moderate to heavy rain showers, and cooler-than-normal temperatures. Frankly, this is very un-August-like weather, with widespread rainfall occuring across much of the eastern half of Texas, and highs of around 90 degrees. And for me, that’s a perfectly fine way to get through the dog days of summer.

Monday

A large complex of storms dropped as much as six inches of rain over central Texas on Sunday night, and this morning the system is moving from the west into the Houston region. It has lost some of its potency, but still could produce 2 to 4 inches of rain over some parts of Houston today as it runs into the moist Gulf of Mexico air mass. Other areas should see less rain, but most of Houston should at least see some showers. Mostly cloudy skies should keep highs in the low 90s. A healthy chance of storms will remain during the overnight hours.

Tuesday

With low pressure (yet another advancing cold front that will stall over the area) and high moisture levels hanging around, I expect another day of widespread showers, with some thunderstorms producing heavy rainfall. For most people accumulations should be under 1 inch on Tuesday, but again there could be some localized street flooding issues under the heaviest storms. Highs around 90 degrees.

Good morning. Houston’s cloudy, on-and-off again rainy weather will continue for several more days. I’ll also discuss the tropics, which seem likely to begin heating up soon as we’re now into August.

Thursday

Most of Houston saw 0.5 to 3.0 inches of rain on Wednesday, and while I don’t think today will be as wet, I do think the region will see fairly widespread showers and thunderstorms later this morning and during the afternoon hours. Accumulations shouldn’t be too concerning—i.e. they’re unlikely to produce some of the street flooding we saw Wednesday. Temperatures will remain pleasant for this time of year, with highs in the upper 80s to 90 degrees.

Friday through Monday

Not a whole lot is likely to change from Friday through the weekend, as a very moist air mass remains settled over the greater Houston region. This will bring partly to mostly cloudy days to the area, and a healthy 40 to 50 percent chance of rain. I don’t think we’re looking at any kind of significant flooding, and accumulations will probably be less than 1 to 2 inches for most areas

Overall, the clouds should be enough to hold temperatures to around 90 degrees for the most part. One warning, if the Sun does come out for a few hours over your location, it will turn hot and steamy fairly quickly.

July was a fairly wet month for the region—most of the area saw about 100 to 200 percent of normal rainfall levels—and August looks to start out the same. This is the time of year when we worry most about drought in southeast Texas, but happily that seems unlikely to be a problem this year. Here’s a look at our wet week ahead.

Wednesday

Atmospheric moisture levels have surged across the area, and we should see the development of widespread showers and thunderstorms later this morning, and they should continue on and off throughout the afternoon and evening hours. While much of the area should see 0.5 to 2 inches of rain, and isolated areas could see a bit more, I don’t think there will be enough precipitation to cause more than street flooding. Highs should remain in the upper 80s due to clouds and rain.

Thursday, Friday, and Saturday

More atmospheric disturbances should move in from the northwest to end the work week, and with atmospheric moisture remaining high we can expect to remain in a gray, wet pattern. I don’t anticipate showers will be quite so widespread as on Wednesday, however. Look for highs of around 90 degrees. If you’re planning outdoor activities on Saturday, it won’t be a total washout, but you’re definitely going to have to keep an eye out for scattered showers.
