I’m not going to lie: for mid-October this weekend’s temperatures and humidity felt pretty gross outside. I know there are some people living here who love summer, and can’t get enough. God bless you. But y’all have had more than five months now. And after a high of 91 degrees on Saturday, and 92 on Sunday, it’s time for a change. Fortunately that is just what is coming with today’s front. In fact, a lot of the region in the 90s this week will be in the 40s (or possibly even upper 30s) by Wednesday morning.
Monday
The front has slogged to the coast already, but it will take some time for drier and cooler air to work its way down into Houston. Accordingly we’re seeing shower activity this morning across much of the northern half of the region, and this should shift closer to the coast later today. Overall rain chances are about 50 percent, with accumulations for those areas that do see rain on the order of one-quarter to one-half inch. High temperatures should remain in the 70s today, with winds out of north and northeast. Low temperatures tonight will drop into the 50s for most of the area, away from the coast.

Tuesday
This will be a chilly day, with highs in the upper 60s to 70 degrees, to go along with mostly sunny skies. Houston will not have had a day as cool as this since March, about seven months ago. Breezy conditions out of the north, with gusts up to 20 mph, will add to the chill. This influx of colder and drier air will set the stage for a cold night, with lows likely in the low- to mid-40s for much of the metro area, and even chillier still further inland. Even Galveston Island should get down into the 50s.

Wednesday
This will be another sunny and cool day, with a high near 70 degrees. Lows Wednesday night will be chilly again, but likely a few degrees warmer than Tuesday night.
Thursday and Friday
A warming trend begins toward the end of the work week as high pressure shifts to our east, and the onshore flow returns. Look for highs in the low 80s both days to go along with sunny skies.
Saturday, Sunday, and beyond
This weekend should see highs in the mid-80s with partly to mostly sunny skies. There is some question about whether another front will push through early next week, bringing some rainfall with it. Quite frankly there is broad disagreement in the models. For now my expectation would be a continuation of warmish weather, in the 80s and low-ish rain chances. We’ll see.
