Heavy rain and thunderstorm activity largely missed the Greater Houston area Saturday afternoon. However, scattered showers and thunderstorms have developed across the area due, in part, to daytime heating.
With some of these cells, small, short-lived funnels may develop. These funnels are very common in a very moist, tropical atmosphere we have overhead. They are small, weak, short-lived, and usually occur near the coast or the bay. Only rarely do the funnels extend all the way to the ground, but when they do they could generate brief gusty winds.
As expected, most of the rain activity has stayed just offshore or east, toward Beaumont and southwest Louisiana, where numerous flood advisories have been issued.
The weather pattern will not change significantly on Sunday, so expect another opportunity for showers and storms, especially along the coast. More funnels are possible Sunday, too. The best opportunity for inland rain will be in the afternoon, when daytime heating may spark storms. High temperatures on Sunday will be near 90 degrees.
