As air temperatures have fallen down near to dewpoint temperatures this morning, we’ve seen the development of radiation fog across much of the Houston area. This should eventually burn off by mid-morning or so, as air temperatures begin to rise.
Tuesday, Tuesday night, and Wednesday
After the fog burns off, skies should become partly to mostly cloudy today, with highs in the mid-60s. Rains should hold off until at least sunset, and as high pressure moves off to the east we should see the development of some scattered, light showers to the west or southwest of Houston this evening.

Lows tonight will only fall into the mid-50s, and we’re likely to see intermittent, scattered showers and thunderstorms during the overnight hours and through 10 or 11am on Wednesday. As for accumulations, for now the models aren’t showing anything too extreme. Accumulations of a few tenths of an inch seem most likely near the coast and in Houston, with one-half inch or perhaps a bit more for inland areas. Skies will remain mostly cloudy on Wednesday afternoon as a cold front nears the area, with highs probably pushing into the mid- to upper-60s.
