Storm threat increasing for Houston on Tuesday

NOAA’s Storm Prediction Center has upgraded the risk of thunderstorms in Houston on Tuesday from “slight” to “enhanced.”

This means the following for the Houston area:

  • Numerous severe thunderstorms are possible across the Houston region, with the greatest chance most likely along the Highway 59 corridor.
  • A few of these storms may be particularly intense, capable of spawning weak tornadoes, damaging winds or hail.
  • Some moderate street flooding is possible where thunderstorm training occurs, but for the most part these storms should move through at a good clip, from west to east.
  • The most likely time for storms will be from 10am to 2pm CT, with clearing likely during the late afternoon hours.

We’ll stay on top of the latest forecast for you.

Severe storms possible Tuesday before a cooler week in Houston

After a weekend of record-setting high temperatures—85 degrees on Saturday and 86 on Sunday—the region will cool down a little today, and a lot on Tuesday. The big concern, as noted my Matt, is the possibility of storms and severe weather on Tuesday afternoon.

Today

A very weak front will slowly move southward through Houston, and likely get hung up near the coast. This will create mostly cloudy conditions, and bring a chance of sprinkles to the area, but no major rainfall accumulations are likely. An easterly wind should help limit high temperatures to the mid-70s. Lows tonight will be in the mid-60s.

Temperatures this morning are in the upper 60s across the Houston metro area. (Weather Bell)

Tuesday

On Tuesday a stronger front will move through Houston, and with a deep source of moisture streaming in from the Gulf of Mexico we’ll likely see some rain showers and possibly some severe thunderstorms with the front. Given the setup it’s likely that most areas see 1 to 2 inches of rains from storms as the front passes through—probably between about 11am CT and 4pm CT on Tuesday. A few areas might see as much as 3 to 5 inches of rain, which could cause some street flooding problems.

After three record highs, Houston finally cools off

What start to the week it has been—three consecutive 80-degree days, and three record highs. Overnight lows, too, have been anomalously warm. Here’s what that looks like in graphical form, with this month’s temperatures plotted against normal levels.

After a cold front the region will see a bit of a reprieve from the heat, but we’ll warm back up this weekend before more seasonable temperatures return next week.

Today

After a cold front moved through on Wednesday, conditions for Thursday will be splendid. Highs should reach into the upper 60s with mostly sunny skies. Lows tonight will fall into the low 50s for most of Houston.

Friday

After a cool start, Friday will warm into the low- to mid-70s as winds begin to swing out of the southeast. This should allow for some clouds to return as well.

Saturday and Sunday

As the onshore flow resumes the region should see a partly sunny weekend, with highs in the upper 70s—some areas will probably hit 80 degrees if it stays sunny enough during the afternoon hours. Beginning on Friday night there will be enough moisture to squeeze out a few scattered showers throughout the weekend, but accumulations should be very slight.

After breaking all kinds of heat records, Houston eyes some relief

Houston set all kind of heat records on Tuesday:

  • Intercontinental Airport reached 86 degrees, breaking the old record of 80 degrees
  • Hobby Airport reached 85 degrees, breaking the record of 82 degrees
  • Galveston reached 80 degrees, breaking the record of 76 degrees
  • It was the earliest 80 degree day for Galveston on record, breaking the previous record by two weeks—Feb. 21 set back in 1993.

There’s more to come today before we cool down a bit for the west of the week.

Today

Some dense fog along the coast will give way this morning to a mostly sunny—and for February, extremely warm—day. The earliest 90-degree day on record in Houston is Feb. 20 (1986), and while I don’t think we’ll reach 90 degrees, I’m not entirely ruling it given what happened Tuesday. Highs should be in the mid-80s regardless before a cool front arrives sometime this afternoon, pushing lows on Thursday morning into the 50s.

The GFS model predicts a front will push into northwest Houston by around noon today. (Weather Bell)
