A gray Saturday and a soggy Sunday morning for Houston

Before we get into the forecast today, we just want to go over some of the news from the National Weather Service office in League City from the last couple days. First off, the tornado that ravaged parts of Pasadena, South Houston, Deer Park, and Baytown was classified as an EF-3.

The tornado in southeast Harris County on Tuesday was rated an EF-3, based on damage to high voltage power towers that had been flattened, a common indicator of a tornado of that intensity. (NWS Houston)

It was the first EF-3 tornado in Harris County since 2002 (La Porte).

Two additional tornadoes have also been confirmed in the Houston area. Both were rated EF-0. One traveled about 14.5 miles from Needville through Thompsons in Fort Bend County. The other occurred in Pearland, preceding the South Houston tornado and was on the ground for a bit over 2 miles.

In Liberty County, an EF-2 tornado has been confirmed, but details are not expected on that until a little later today.

The last couple days have been mercifully placid, and we look to get one more of those before some more rain.


Friday should be a mostly fine day, with intervals of sun and clouds and temperatures popping up to near 60 degrees.


Clouds will really increase and thicken up tonight into Saturday. By late tonight and early Saturday morning, a few showers should begin to break out, along with periods of drizzle or light rain. We don’t currently expect Saturday to be a washout, but you’ll probably see a few raindrops in much of the area. The clouds and showers will compete with warm air flowing in from the Gulf of Mexico, so after a mild morning in the mid or upper-50s, we will likely warm to near 70 degrees. You will also notice the wind picking up some on Saturday afternoon, with gusts to perhaps 25 mph or so.


The next in a series of systems will impact us late Saturday evening and Sunday. Look for rain to break out as a coastal low develops. This system will lack much of what Tuesday’s had for significant severe weather. We do not expect serious severe weather, but a few stronger thunderstorms are possible. That said, we have plentiful moisture available Sunday, and we will be looking for the potential of locally heavy downpours, especially in the morning. This would be most likely south of I-10.

The southeast half of the Houston area has been placed in a slight (level 2/4) risk for excessive rainfall on Sunday, meaning localized downpours could lead to some street flooding. (Pivotal Weather)

Right now, the Weather Prediction Center has the region in a slight (level 2/4) risk of excessive rainfall. We don’t expect rain quite of the intensity we saw on Tuesday, but given the wet ground, we could see some areas of ponding or street flooding emerge Sunday morning under the heaviest rain. In addition, water levels on creeks are still high in parts of the area, especially north and west of Houston, so any heavy rainfall will likely exacerbate that a bit. Expect an inch or two on average southeast of Houston, with lesser amounts as you go north and west of the city.

Conditions should gradually improve later Sunday afternoon and evening. We will top off in the 70s.

Early next week

Early next week looks dominated by this front that gets hung up over our area on Sunday. That will likely be in place through Wednesday. The problem from a forecaster’s perspective is that it’s going to wobble around. That means that there’s probably going to be a pretty annoying gradient of temperatures over the region next week, with readings ranging from the 50s to the 70s depending on the exact position of the front. In addition, rainfall will be possible through the entire period, although it looks mostly minor in nature until later Wednesday or Thursday. We should have a little more clarity on the exact daily details Sunday or Monday.

Total rainfall through next Friday morning should be 1 to 4 inches across most of the region. Higher amounts are possible in spots, especially south and east of Houston. Some lower amounts may occur north and west. (Pivotal Weather)

Next front

Our next real front of significance after Sunday will come on Thursday it appears. Expect a period of showers and storms, along with some locally heavy rain. This should usher in a slightly less active pattern and a chilly air mass in time for next weekend. We do not expect a significant freeze at this point, however. We’ll update you on that Monday (or Sunday!) as well.

  1. The amazing thing is nobody was killed or seriously hurt. When I was a teen, I saw an F5 that killed 32 people during the Super Outbreak. Of course, the warning systems weren’t rapid or very effective. You had to wait until someone eye-balled the funnel (not really possible at night),called it in (probably from a land-line) and then someone had to activate the sirens (if your community even had them), and you had to be in a place where you could hear them. We’ve come a long way.


  2. @Travis: I am in the Heights area. Walking up Shepherd/Durham is dangerous, it is full of mud slicks, I have gone down a couple of times. Riding a bicycle to work along the White Oak Bayou Trail, I noticed this week large stretches of mud, sometimes a few inches deep. Now, heavy rain always brought debris onto the trail, but never mud like this. I would attribute it to all of the construction, with the mud along Shepherd/Durham, many of the cross streets (15th, 16th, 20th), along Allen Parkway, and more. The mud slicks wash into the drains, then into the bayous, then are deposited on the trail. It is just not good. I can’t believe that there is a chance of rain all week.

  3. You mention an EF-0 tornado from Pearland to South Houston. The big tornado also began in Pearland, at El Franco Park. (A friendlost fence just south of the park, and street signs were down.). Were there two different tornados beginning in Pearland, or could the EF-0 be the beginning of the big tornado
