Cool conditions continue with showers returning to start the week

HOUSTON, Texas (KTRK) -- Cool conditions continue early on this week with showers returning to Southeast Texas pretty quickly as well.

Temperatures Sunday evening will drop to low-mid 50s by Monday morning as clouds move in and lead to more of a cloudy day Monday. There's also the chance for showers west of I-45 starting off in the morning hours, but more so in the afternoon. Scattered showers will continue to push in from the west where some light rain could impact your afternoon and evening in Houston. Generally the rain chance along and east of I-45 is about a 30% chance, where west of I-45 and closer to the Hill Country is about a 40 to 60% chance. More widespread rain is expected Tuesday.

How long does this cooler weather stick around for?

Below normal temperatures will stick around Southeast Texas through Wednesday thanks to weekend cold front and our next weather system moving in. Cloudy conditions and showers will keep afternoon highs in the low-mid 70s with morning lows through Wednesday staying within the 50s. By Thursday is when we should see a spike in temperatures with afternoon highs climbing back into the 80s.

What's bringing this next chance for rain?

A disturbance in South Texas will pass by and offshore to the Gulf early on this week. So Southeast Texas will be on the northern extend of this system and the rain it could send to southcentral Texas. Monday there will still be enough drier air overhead to limit rain across most of the region, though areas west of I-45 could receive a few rounds of light to moderate showers during the day. The better chance for more widespread rain will be on Tuesday with a few more rounds of showers possible on Wednesday. So keep the umbrella handy this week! And at this time no severe weather is expected, but a few areas that receive the heaviest downpours could have some minor street flooding.

What's the early outlook for next weekend?

Temperatures will rise back into the 80s by next weekend and so will the humidity too. A few showers and storms are possible each day Friday through Sunday, though no day looks to be a washout at this time.
