Good morning. Some isolated showers have moved into the Houston are this morning as a southerly flow returns from the Gulf of Mexico. Hopefully more of the area will see rain later today before high pressure settles in. Either way the heat and humidity is coming back for a good long while.
Today
Some of the high-resolution models show pretty decent shower coverage later this morning and during the afternoon hours, as daytime heating develops. Some areas may receive as much as one half to one inch of rain today (others won’t see any, alas), and partly to mostly cloudy skies should limit high temperatures in the mid- to upper-80s. Lows tonight will be in the lower 70s.
Wednesday through Friday
After today we’re going to see higher pressures dominate Houston’s weather for the rest of the work week, and it’s not going to be fall-like at all. Days should be mostly sunny with highs in the upper 80s to possibly even 90 degrees. Overnight lows will be around 70 degrees north of Houston, and in the low 70s in the city and closer to the coast. We can’t rule out some storms on Friday as a cool front moves into northern Texas, but I don’t think the showers and thunderstorms associated with that front will make it all the way to Houston (the front itself won’t, unfortunately).
