Earlier today, I did a short telephone interview with The Weather Channel. Nice people. But they were really playing up the potential for serious flooding in Houston tonight. I offered a mild correction—that this was kind of a characteristic spring storm, and not something too worrisome—but that message seems to be getting lost. So let me reiterate it: Yes, some heavy rains are coming to the region this evening, and during the overnight hours, probably widespread accumulations of 1 to 4 inches, with higher isolated totals. No, we don’t expect widespread mayhem.

The setup for heavy rainfall is clear; a slow-moving cold front is moving toward Houston and lifting the warm, moist air at the surface. Some training of heavy thunderstorms is possible as the convective activity feeds off of the warm Gulf of Mexico moisture. Fortunately, the front itself should move off the coast on Thursday, taking this mess with it. Here’s the outlook for Houston until then.
