Small chance for a summer downpour continues on Wednesday

HOUSTON, Texas (KTRK) — Small but heavy rain showers will again pop up on Wednesday, but the chances you’ll cross paths with them are only 30% south of I-10 and 20% north of I-10.

A fresh batch of moisture arriving overnight will bring pockets of rain south of I-10 for the morning driving time. Temperatures will start off in the mid 70s at sunrise, then warm into the mid 90s in the afternoon. That’s when isolated downpours could pop up around Houston. Some of the showers could even throw down a few lightning bolts. Where it rains, temps will quickly drop into the mid 80s.

What’s in store for the rest of the week??

Heat levels will continue to climb with highs near 100 by Friday. Humidity levels may be high enough to warrant a Heat Advisory somewhere in Southeast Texas. Peak heat index values in the afternoon will range between 105 to 108 degrees. Rain chances will remain slim at 10-20%.

Will we finally get a rain-free weekend?

Maybe. The rain chance is still at 20%, but it does look less stormy than just about every weekend we had in July. Next week, the stormy weather pattern returns to the Gulf coast with a 30% chance of daily afternoon downpours.

What’s happening in the tropics?

Tropical Storm Dexter will remain a fish storm over the Atlantic and pose no threat to land. We are also monitoring two areas of potential development, one off the East Coast and one over the central Atlantic. We continue to see signs that the tropics may become even more active the second half of August as wind shear relaxes across the Gulf, Caribbean, and West Atlantic. Meanwhile, the Eastern Pacific remains very active. For a thorough update and in-depth video on what’s happening in the tropics, head to our tropical update page.
