It’s going to feel nearly 50 degrees colder by Monday morning.

HOUSTON, Texas (KTRK) — Summer is here for the weekend, it will feel about 50 degrees colder by Monday morning!

Temperatures Saturday evening will fall from the mid 80s to upper 70s overnight under a partly cloudy sky. The humid and summery weather will stick around for most of the day Sunday, but that approaching cold front will really shake things up later Sunday evening. A few showers will develop ahead of and along the front late Sunday afternoon and we keep scattered showers in the forecast through Sunday night as the cold front moves in from north to south. Heavier showers are possible along the coast Sunday night as the front interacts with a breeze out of the gulf.

Then behind this front will be cold. breezy and rainy conditions providing a completely different forecast for Monday.

When is that strong cold front supposed to arrive?

It now looks like the cold front will enter Southeast Texas early Sunday afternoon and reach Houston around sunset, or sometime between 6 p.m. and 8 p.m. So high temperatures for most of the region Sunday will be back in the mid 80s but quickly plummet once that front rolls through.

How cold will it get behind this front?

By Monday morning it will be in the 40s, and there are signs that if we get enough rain, it might stay in the 40s all day! And that’s with a north wind gusting up to 30 mph. Tuesday will only warm into the upper 50s, so you’ll want a warm jacket for the last two days of October. Once the clouds clear out by Wednesday, it will get even colder at night. Next Thursday, we could get our first morning this fall with widespread lows in the upper 30s!

What’s the outlook for trick-or-treat time next Tuesday?

Temperatures will slowly dropping through the 50s as the evening goes on if the clouds are still around. If the clouds clear by trick-or-treat time, it could quickly cool down into the 40s. We now believe any light rain showers that pop up on Halloween will be mostly confined to the morning hours, so it should be dry by evening!
