Despite a tropical air mass, rain showers have been really hit or miss across the Houston region over the last four days. Some areas, like The Woodlands, have picked up 3 or more inches of rain. Other parts of south and central Harris County have received no rain at all. Pretty much everyone has seen a lot of gray skies, but that will now change as tropical moisture from former Hurricane Barry moves away, and high pressure moves into Houston.
Tuesday
Bit of a tricky forecast for today, as atmospheric moisture levels remain elevated, and high pressure really hasn’t begun to assume control of our weather just yet. However, there are no significant forcings for rainfall today, so we’re probably looking at scattered showers and thunderstorms today—not the kind of slow-moving clumps of storms we saw on Monday in areas like southern Montgomery County. A few areas may pick up a half inch of rain, or so, but most of Houston will probably remain dry. Skies otherwise should be partly sunny, with highs in the low 90s.

Wednesday and Thursday
As high pressure builds over the area, we should start to see mostly sunny days, with rain chances only in the 10 to 20 percent range (mostly during the afternoon, along the sea breeze). These will be prototypical July days for Houston, with lots of sunshine, and highs in the low- to mid-90s. Nighttime temperatures in the upper 70s won’t offer much relief and the humidity will add to the sultry mix.
