HOUSTON, Texas (KTRK) — An ABC13 Weather Watch has been issued for Saturday as a squall line could produce severe weather, and the Storm Prediction Center just upgraded the severe weather risk for Houston. Isolated severe storms capable of producing tornadoes are possible in the late afternoon, then minor street flooding and isolated power outages are possible Saturday evening when the main squall line blows through Houston.
Clouds will build in today ahead of the storm system, but it should stay mostly rain-free with highs reaching into the upper 70s. Dense sea fog is likely to persist in our coastal communities most of the day.
What should we expect with the storm system arriving Saturday?
Rain chances will vary throughout the day with the morning being your most likely time to stay free of rain and thunderstorms. A passing shower is possible at any time during the day, especially in the afternoon, but the squall line of thunderstorms will likely hold off until the late evening hours. New data indicates during the 3PM-6PM window, some of the showers forming ahead of the main squall could blossom into rotating thunderstorms capable of producing tornadoes. After that, we’ll have to monitor the main line of thunderstorms for gusty winds, heavy rain, and lightning as they blow through in the evening hours. We expect the squall line to impact Houston between 8PM and 10PM and reach Galveston sometime in the 10PM-12AM window.
What’s the expected impact for the Knights of Momus Grand Night Parade in Galveston Saturday?
Sea fog and showers are possible during the parade, and while we cannot rule out thunderstorms, the current timing favors any thunderstorm activity to hold off until late in the night for Galveston after the parade ends. Either way, have an umbrella or rain poncho on hand just in case!
Could we get another freeze this season?
Sure, but we likely have to wait until near the end of February or beginning of March for our next chance of freezing weather if it were to occur. On average, Houston’s last freeze occurs around Valentine’s Day.
