Tropical moisture set to bring back downpours, ABC13 Weather Watch for Monday

HOUSTON, Texas (KTRK) -- We are in a typical summertime weather pattern for the rest of the week, but we are eyeing a pattern change over the weekend that has us putting out an ABC13 Weather Watch for Monday. 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.

Thursday morning will remain mostly dry but very warm with lows barely below 80 degrees. It will be hot and humid 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% and 70% odds, respectively.

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.
