The high temperature on both Saturday and Sunday topped out at 90 degrees at Bush Intercontinental Airport, making for a warm weekend. If you’re tired of Houston’s long, long summer—the region had its first 90-degree day back on April 9 of this year—the good news is that we’re probably done with 90-degree days for 2019. In fact, we should mostly be in the 70s for this coming week and weekend.
A line of storms will push through Houston at around sunrise, or a little before, on Monday morning. A few of these storms are fairly strong, but the line is moving from northwest to southeast fairly quickly, so we don’t have any flooding concerns. Most areas should see about one inch of rain. Unfortunately the storms will hit during the morning commute for some people. The front should be off the coast by or before noon. In the wake of the front, highs today should hold in the 70s, with most of Houston falling into the upper 50s on Monday night with clearing skies.
Tuesday and Wednesday
These will be a pair of gorgeous days, with cool mornings in the upper 50s (except along the coast), mostly sunny skies, and highs in the upper 70s to possibly 80 degrees. An onshore flow resumes on Wednesday night, which should nudge lows into the mid-60s.
Thursday and Friday
As moisture levels increase in the atmosphere, humidity and better rain chances will follow. With a mixture of clouds, highs aren’t going to get much above 80 degrees. However, it will be sticky, and with 60 to 70 percent rain chances by Thursday night most of the area probably can expect 0.5 to 2 inches of rain on Thursday and Friday ahead of the next front. Speaking of the front, it probably will arrive some time on Friday, Friday night, or Saturday morning—clearly the timing is not certain
Saturday and Sunday
Saturday’s weather will depend on the timing of the front, but at some point we’re going to transition from warm days of around 80 degrees to dry days with highs of around 70, and overnight lows possibly in the 40s for areas north and west of downtown Houston. After the front hits, Houston should see a really nice, and dry rest of the weekend.
And what of Halloween? After this coming weekend’s front, we will likely see a warming trend for next week. Halloween comes on that Thursday. The weather for that day will depend on the timing of the third front from now, which likely will come perhaps a day before Halloween, or on the day itself. If its the latter, that could make for wet trick-or-treating, but it is simply way, way too early to have much confidence in a forecast.
