Tropical downpours return soon, ABC13 Weather Watch Monday and Tuesday

HOUSTON, Texas (KTRK) -- We are in a typical summertime weather pattern through Saturday, but we are eyeing a pattern change late this weekend that has prompted an ABC13 Weather Watch for Monday and Tuesday. That's when high levels of tropical moisture collide with June's version of a cool front, which could bring torrential downpours and flash flooding to parts of Southeast Texas. Until that pattern change occurs, expect highs in the low 90s with heat index values above 100 each afternoon.

It will be hot and humid on Thursday with only a 20% chance of a cooling downpour.

When does the tropical air return with higher rain chances?

That will occur on Sunday. At this time we have rain chances at 30% Saturday and 60% Sunday, but the highest chance over the next 10 days is currently reserved for next Monday and Tuesday with 80% odds. A significant flooding event is possible on those days when a cool front interacts with that moisture. The front could focus a band of training storms with torrential rain. Stay tuned!

Why does it feel so hot even though the air temperature is barely hitting 90?

It has everything to do with the wet ground and high humidity. True, our highs are only hitting the low 90s, but when you factor in all that humidity, it feels about 10 degrees hotter to our bodies.

What are you tracking in the tropics?

Cristina has dissipated in the Pacific, but the remnant moisture is coming for the southwest Gulf. The National Hurricane Center has given the remnants of this storm a 10% chance of re-forming into an Atlantic tropical system over the Bay of Campeche. That's the moisture that surges in here this weekend and early next week.
