Two more days of record-setting highs, and then finally more fall-like conditions

In brief: Houston faces two days of record-setting heat before a nice front arrives on Tuesday night to usher drier and cooler air into the region for the rest of the week. Rain chances, unfortunately, continue to look fairly low. Also, if you have a clear view of the Western sky, we encourage you to look for a new comet near the horizon.

Houston likely to set record high

The region’s high temperature on Sunday was 94 degrees, which is one degree short of the city’s record high for October 13. Today we’re likely to be even a bit warmer, with highs in the mid- to upper-90s for much of the metro area. And the record high for today, set in 2015, is just 92 degrees. So we’re almost certain to set a record today. Tomorrow we are also likely to set a record, beating the mark of 92 degrees set in 2019. A cold front finally arrives on Tuesday night to bring us some much-needed relief.

Don’t miss a comet in the night sky

If you have a clear view of the western horizon, preferably with few lights (i.e. not looking directly toward downtown Houston), you should try and see a comet with an unwieldy name, C/2023 A3 Tsuchinshan-ATLAS, this week. To find it, look toward the western horizon within 45 minutes of sunset at twilight. A pair of binoculars should only enhance the view, so if you have some, bring them along. The comet will fade in the next two weeks, so right now is the best time to try and see it.

Monday and Tuesday

Heat continues for two more days. Both Monday and Tuesday will be sunny, with high temperatures in the mid- to upper-90s for most locations away from the coast. This is brutal, August-like heat that is very much not normal for October (hence the record-setting temperatures). At least the dewpoints will be a little lower, so it won’t be incredibly sultry heat. Winds will be light, from the north and northwest, at 5 to 10 mph. Monday night will be warm, with lows in the upper 60s.

Wednesday

Drier air starts to move into the area by around midnight, and dewpoints will fall into the upper 30s area wide by Wednesday morning. It will feel noticeably drier, and daytime temperatures on Wednesday may be only on the 70s. Winds will be from the northeast, gusting up to 20 mph. Skies will remain sunny, as this is a dry front. Lows on Wednesday night will drop into the 50s area-wide, except for the immediate coast.

Thursday and Friday

These will be a pair of mostly sunny days, with high temperatures in the upper-70s to lower-80s, with nighttime temperatures in the upper-50s to lower 60s. So, pretty pleasant.

Saturday, Sunday, and beyond

We may start to see some clouds this weekend as a southerly flow returns. Whether that brings any meaningful rain chances is something we’ll have to wait and see, but overall the odds do not look great. Highs are likely to be in the mid-80s for much of the region, with lows in the 60s. There’s probably another front in the cards some time next week, but the details are hazy.
