In brief: We’re interrupting your Sunday morning to bring an updated forecast for the arrival time of a strong cold front this evening. Not much has changed since our forecast on Friday, but we want people to be aware of what is coming in terms of wind.
What to expect and when to expect it
Today will be a warm one, with high temperatures in the mid-80s, partly to mostly sunny skies, and a decent amount of humidity. Yes, it’s a little warm for March, but otherwise nothing out of the ordinary. However a fast-moving front this evening will bring a rapid change.
In terms of timing, I expect the front to probably reach areas such as Katy and The Woodlands between 5 and 7 pm CT, central Houston, including Sugar Land and Baytown, between 6 and 8 pm, and Galveston by 7 to 9 pm this evening. There will be a brief possibility of showers and thunderstorms (there is a slight chance of some of these becoming severe, but for most of us probably not). Anyway this front will be moving so the showers will not last long. There has been some internet chatter about a derecho, but we don’t have any expectations for that kind of event.

What will be immediately perceptible is an abrupt wind shift, from a southerly flow to strong gusts from the north. Wind gusts behind the front will be up to 45 mph across Houston, and this is strong enough to blow things around. It is advisable to secure loose objects and really take care driving. The strongest wind gusts will persist overnight before settling down a little bit on Monday morning (to maybe around 30 mph).
This won’t be a “Blue Norther” type front with temperatures dropping sharply immediately. I expect them to fall 5 to 10 degrees after the front’s passage, and then steadily drop with temperatures in the low 50s by midnight, to around 40 degrees by Monday morning. So with the wind chill it will be very cold on Monday morning, possibly feeling like it’s about 30 degrees outside. You’ll definitely want to bundle up.
We’ll be back at that time with a full weather update for you.
