It took awhile last night, but cooler air finally did move into the Houston metro area, and temperatures have fallen to around 50 degrees this morning across most of the city.
As expected, today will be gorgeous, with highs in the low 70s, lots of sunshine and dry air. Too bad it’s Monday!
We’ll begin to see the return of Gulf moisture late on Monday, and that will lead to the possibility of some scattered showers on Tuesday afternoon. This will also bring daytime temperatures back to around 80 degrees. I’ll also be watching the approach of a low pressure system in the upper levels of the atmosphere now located near Washington state (see map below). This will have the potential to cause some problems on Wednesday.

This upper level energy, combined with the Gulf moisture, will bring a chance of severe weather to the region on Wednesday, likely during the afternoon hours. The chance of thunderstorms will be greatest to the northeast of Houston, says NOAA’s Storm Prediction Center, in the graphic below.

I don’t expect a whole lot of rain on Wednesday, perhaps a few tenths of an inch for most areas. We’ll stay on top of the severe weather possibilities.
A cold front will arrive sometime on Thursday, perhaps during the morning hours, and we may see some more light rain lingering through the early afternoon. Lows should fall into the 50s Thursday night.
FRIDAY and SATURDAY
Enough moisture will remain behind such that we can’t completely discount the possibility of light rain following the front, and we should see a couple of partly cloudy days with highs in the 70s.
Right now Sunday looks spectacular, with sunshine and highs in the 70s.
