Houston just enjoyed a splendid week of weather, and truth be told there’s more great fall-like weather to come for the region—nothing too hot or too cold. However, winter is not too far off. And as this graphic published on Twitter by climate scientist Brian Brettschneider shows, we are entering the historically coolest period of weather for the region:

This indicates that the coolest 90-day period for Houston (and most of the Gulf Coast outside of Florida) runs from the end of November through the end of February. And indeed, there are some signs of more winter-like weather in the extended forecast, as I’ll discuss below.
Monday and Tuesday
After a cool start to the work week, highs will jump up into the mid-70s on Monday, and upper 70s on Tuesday. With relatively dry air (especially on Monday) and sunny skies, both days should feel quite pleasant, and nights will be mild with lows in the upper 50s to 60 degrees. As moisture levels begin to rise Monday night, we could see some fog on Tuesday morning.
