Humid air rolls back in, tropical moisture brings more downpours this weekend

HOUSTON, Texas (KTRK) — Humid air is pushing back through Southeast Texas and will stick around through the weekend.

Some places north of Houston dropped into the mid 60s on Thursday morning, but because of the returning humid air, temperatures Friday morning will only cool off into the mid to upper 70s for most. Highs will make it back into the mid 90s, and you’ll notice high clouds blowing in from the west. That is moisture from former Pacific Hurricane Lorena, which will boost our rain chances this week.

So what’s in store for us this weekend?

More opportunities for rain. Tropical moisture is blowing in on Saturday and increasing more on Sunday as a front approaches from the north. The higher moisture levels will boost the chances for heavy rainfall that could briefly flood streets. We currently have a 30% chance for a downpour Saturday, and that rain chance doubles up to 60% Sunday as the tropical moisture sits overhead and gets squeeze by a front pushing in from the north.

A front?! Will it bring us any cooler weather?

Maybe. We don’t want to get your hopes up too much, but our best read on the front right now is that it will bring a strong enough push of drier and slightly cooler air to possibly drops lows into the upper 60s and highs into the upper 80s for a day or two. The last time Houston’s official thermometer dropped into the upper 60s was at the end of May! Look for the front to blow in drier air as early as Monday.

What is happening in the tropics?

A tropical wave in the eastern Atlantic has a high chance for development and becoming Gabrielle. While the Gulf is quiet now, we continue to see signs activity will pick up across the Atlantic basin by mid-September. Meanwhile we have now hit the time of year where we pay closer attention to Pacific hurricanes that can send their moisture and rains toward Texas, like Lorena is expected to do this weekend.
