Houstonians are experiencing a temporary decrease in humidity as cooler air from Tuesday’s front continues into Wednesday, bringing a brief change to the city’s usual weather conditions. According to the National Weather Service, today will be mostly sunny, with an expected high near 91 degrees and northeast winds shifting southeast in the afternoon.

As the day moves into evening, nighttime temperatures are forecasted to drop to around 74 degrees, reaching a balance between the day’s warmth and the cooler night air, before humidity levels rise again. Dew points are projected to climb into the upper 60s to lower 70s across Southeast Texas, as reported by the Houston Chronicle.

Temperatures are forecasted to rise over the next few days, with Thursday reaching a high near 94 and Friday close behind at 93, under mostly sunny skies. Along with the rising temperatures, humidity will increase as well, causing heat index values, or the humidity-driven "feels like" temperatures, to climb back to around or slightly above 100 degrees through Friday, according to reports from the Houston Chronicle.

Tonight’s forecast predicts partly cloudy skies with a low around 74, but the rest of the week is expected to bring increasing discomfort. The dry heat felt today will be replaced by warmer, more humid air. For Memorial Day weekend, the Houston Chronicle reports a 40 percent chance of showers and thunderstorms, along with partly sunny skies and temperatures peaking near 89 degrees. Humid conditions are expected to follow in the coming days.

For those looking ahead, the National Weather Service points to a similar pattern heading into the next week, with a persisting 40 percent chance of showers and partly sunny conditions.
