Front blows into Houston Wednesday night, rain chances climb higher Friday and Saturday

HOUSTON, Texas (KTRK) -- Another cool front is coming to Houston, and like the one we had last week, the highest rain chances will occur a couple of days after the front arrives.

Overnight it will stay cloudy and muggy for most with low temperatures only in the mid 70s. That's about 10 degrees above normal.

We expect limited cloud breaks during the day, pushing high temps back into the mid 80s. A few showers are possible during the day. Your chance of getting rain is 30%. The front should blow into Houston sometime after sunset, with a modest cool down coming our way Thursday under a mainly cloudy sky.

Is severe weather still possible late Wednesday when the front arrives?

Yes, it is possible, but it increasingly looks unlikely. A "cap" of warm, stable air aloft is expected to stay strong enough to prevent thunderstorms over most of Southeast Texas. That said, if the "cap" doesn't hold and thunderstorms develop, then all modes of severe weather are possible including severe wind gusts, large hail, and even a brief tornado. The chance of being near a severe thunderstorm in Houston is about 5%, and it increases to 15% once you get to Conroe and locations northward.

When do the rain chances peak this week?

It's honestly a tricky forecast when it comes to rain chances this week, but we do want to lower your rain expectations for Wednesday and Thursday and bring them up for Friday and Saturday. With the cap of stable air looking stronger on Wednesday and Thursday, we have lowered rain chances down to 30%. An upper level low will blow in from the west on Friday and Saturday, activating storms along and north of the stalled front. We have increased rain chances to 40% both days, and there is room for those odds to go up.

How does it look for Mother's Day?

Mother's Day should be warm and humid with lows near 70 and highs in the upper 80s, but we are tracking another front that will blow in sometime that day. This front will come with a 30% chance of showers and thunderstorms.

What's the latest on drought conditions with all this rain?

We've already seen the drought end over parts of Houston, and last week's round of rain likely ended it over more of Houston and Harris County. We'll get official word on Thursday when the new Drought Monitor report is released. Expect drought improvement just about everywhere in Southeast Texas.
