Tropical moisture brings more chances for needed rainfall Wednesday

Keep the umbrella handy! Scattered downpours will pass through Southeast Texas the next several days.

HOUSTON, Texas (KTRK) -- Keep the umbrella handy! Scattered downpours will pass through Southeast Texas the next several days.

Tropical moisture pushing into parts of Southeast Texas Wednesday and Thursday should yield the highest chances of rain for the rest of the week. Scattered showers could pop up especially south of I-10, over our coastal counties. It will be another hot afternoon with highs in the low-to-mid 90s, and it's during the noon to 3 p.m. window that showers and thunderstorms should be most prevalent in and around Houston. A quick inch or two of rain is possible in the heaviest storms. Your chance of rain is 40%. All the rain should dissipate sometime between 7 p.m. and 8 p.m.

What are those rain chances for the rest of the week?

We have 40% odds for Wednesday and Thursday. After Thursday we have a 30% chance of rain for Friday and the weekend.

Are anymore triple-digit temperatures in the forecast?

Nope! But...temperatures will stay above normal for the next 10 days. That means afternoon high temperatures in the low-to-mid 90s, and when you factor in the humidity, it'll definitely feel like the triple digits with a heat index above 100..

Are you seeing any signs of a fall front coming this way?

Not over the next 10 days, but it's possible a fall-ish front could slip in during the last 10 days of September.

What are you tracking in the tropics?

Lowell continues to pull away from Hawaii, meanwhile the Atlantic remains quiet here at the peak of hurricane season. For a more in-depth discussion on what's happening in the tropics, visit our Daily Tropical Update page.
