Houston is in for a week of shifting weather, with warm temperatures midweek, dense morning fog, and a cold front set to bring cooler air as the weekend approaches. If you’ve been enjoying the sunshine and warmth, get ready for a change—by Thursday, temperatures will start to dip, and by Sunday, you’ll feel the difference.
The week kicks off with highs reaching the low 80s, making it feel more like spring. However, dense fog in the mornings could cause low visibility during commutes, so drivers are urged to use caution. A cold front moves in late Wednesday, gradually lowering temperatures into the low 70s and upper 40s overnight by the end of the week.
Why Is Houston’s Weather Changing?
The warm spell early in the week is due to southerly winds and high pressure, allowing temperatures to reach a comfortable 81°F (27°C) by Wednesday. But don’t get too used to it—a cold front moving in from the north will shift winds, bringing cooler, drier air that will gradually lower daytime highs and make for chillier mornings and evenings by the weekend.
In addition, the combination of high humidity and clear skies will create dense fog in the mornings, especially through Wednesday and Thursday, before drier air arrives and clears things up.
