It’s been a somewhat dreary winter so far, but we’re now entering a period in which high pressure may dominate our weather more—not all the time, to be sure—and this should bring us a nice string of mostly sunny days. If you like cooler, sunny weather, the coming forecast period should be perfect for you. Also, the weather for the Houston Marathon looks increasingly likely to be cold.
Friday
After a cool start in the 40s for most of Houston, the region should warm into the mid-60s today under mostly sunny skies. It should be a pleasant day before a cold front approaches from the west and pushes through the area. Lows tonight will be in the 50s for the most part.

In terms of rainfall, some scattered showers are possible this evening, and then a line of broken showers and thunderstorms will develop later, likely pushing through Houston from west to east between 10 or 11pm Friday night and sunrise on Saturday. We still expect most areas to see one-half inch of rain, or less from this system, but there could be some higher isolated totals. We don’t anticipate any problems from the rain.
Saturday
Rains should end around sunrise, or shortly thereafter, and the remnant clouds should dissipate by around midday if not before. Highs will reach into the mid- to upper-60s under sunny skies, with drier and eventually cooler air blowing in from the northwest. Saturday night will be chilly, with lows dropping down to around 40 degrees in the city of Houston, and upper 30s for inland areas, most likely.
