Some surprise storms will move into Houston this afternoon

Well, some days Mother Nature can still surprise you.

As late as last night it appeared the atmosphere would dry out at all levels in the wake of Friday night’s cool front. However, that has not happened sufficiently. As a result, a fast-moving kink in the atmosphere will cross Houston from west-to east from around 1pm to 4pm today, and have enough moisture to work with to produce storms. The threat is briefly heavy rainfall and hail.

The storms should clear the area quickly, and we expect mostly sunny weather before and after, with a pleasantly cool evening. Low temperatures on Sunday should drop into the upper 50s for areas north of Houston, and we do expect a fully sunny day for the second half of the weekend.

Deadly tornado passes north of Houston, sedate weather ahead

Good morning. Storms passed to the north of Houston on Wednesday evening, and the severe weather produced one particularly strong tornado that touched down just north of Huntsville and Livingston, striking the community of Onalaska hard. Meteorologists from the National Weather Service will investigate the location today to determine the intensity of the tornado and its path.

Local residents described the tornado as “devastating,” and at least three people were killed. As most of us went to bed last night, this small community was looking for lost people, assessing injuries, and finding temporary shelter outside their damaged or destroyed homes. Tornadoes this strong in the greater Houston region are rare, but possible. The following image shows the storm’s path as indicated by rotation on radar.

The entire Houston metro area will now settle into a much more sedate weather pattern, with sunny weather for days and days.

Thursday

A cool front is moving into Houston this morning, and this will help drop moisture levels today. This, in turn should help to clear skies by mid- to late-morning. Light winds will blow out of the north. This afternoon, high temperatures will reach the mid- to upper-80s under sunny skies. As the sun dips toward the horizon tonight, we’ll be in for a real treat as the drier air allows temperatures to drop into the 70s and then 60s overnight.

Storms possible later today, but the bigger threat lies north of Houston

Houston will see the threat of severe weather this afternoon and early evening as a storm system moves through the region, ahead of a cool front. After this we expect several days of dry, sunny weather to dominate the region. It will be warm, but not too warm for late spring, with some reasonably cool nights this weekend.

Wednesday

Temperatures this morning are in the mid-70s, with cloudy skies. Unlike Monday and Tuesday, however, we won’t experience much if any clearing skies later today. Instead, the region will see an increasing chance of storms. The bigger threat lies north of the metro area, over areas such as Lufkin and Waco, but almost the entire Houston region faces a “slight” chance of hail and damaging winds. The rain chances with this storm system are pretty meager for Houston, especially areas south of Interstate 10, as the capping inversion may prove unbreakable. That’s unfortunate, because there are a lot of dry areas such as Brazoria County that could use some precipitation and probably won’t get much, if any with this system.

Thursday

A secondary, thin and broken line of showers may pass through the area early Thursday before sunrise along with the cool front itself. In its wake, we should see clearing skies and highs in the mid-80s on Thursday. Lows will drop into the mid-60s.

Lots of sunshine and some fairly dry air this week in Houston

The good news is that if you enjoyed Monday’s weather we have plenty more days like that this week—warm, but not too warm, with lots of sunshine. Wednesday will be the only real exception to that. Our weekend weather also looks pretty fine if you’re looking for sunshine and drier air.

Tuesday

Any patchy fog this morning should burn off quickly, and like on Monday we should see a transition to partly to mostly sunny skies this afternoon. However, with winds turning to come from the southeast later today we expect clouds to return pretty quickly this evening to make for mostly cloudy skies. Highs today should reach the low 80s for most people, with low temperatures Tuesday night falling to around 70 in the city—lower inland, and warmer along the coast.

Wednesday

This is the one day this week the potential for some dynamic weather. An upper-level storm system will drop down toward Texas on Wednesday, but the effects look to be most pronounced for north and east Texas, with the Houston metro area on the southern periphery of the action. Models suggest that a mass of showers and thunderstorms will move through Houston during the afternoon or early evening hours on Wednesday, with the better organization north of Interstate 10. Areas such as Montgomery County and points north may see 0.5 to 1.5 inches of rain, while much of the rest of the region sees a few tenths of an inch or less. Highs Wednesday will be around 80 degrees with mostly cloudy skies.
