Originally published at: A warming trend begins for Houston, but some showers and fog may accompany it on Wednesday – Space City Weather
In brief: A warming trend takes over today in Houston with 60s likely. Rain showers or an isolated thunderstorm and areas of fog arrive tomorrow for some, not all of the area, while a very warm day sets up on Thursday. A cool front will disrupt the warming trend Friday before we surge upward again. Record highs will be at risk next week in Houston.
We’re starting off warmer this morning. In most cases, we’re running about 8 to 12 degrees warmer than Monday morning at the same time.
Tuesday
Warmer will indeed be the theme today. While it should be sunny today, there will be a fair bit of high cirrus around to dim the sun at times. Otherwise, we’ll manage 60s this afternoon and a generally lovely late autumn day.
Wednesday and Thursday
Wednesday looks like our best chance at scattered showers over the next week or so. A lot of folks will see nothing. But in general, expect low clouds, some areas of fog, and scattered showers or even a rogue thunderstorm tomorrow. Highs will shoot up to about 70 degrees.
The potential for fog, especially sea fog returns Wednesday night and Thursday morning as rain chances diminish and a warmer, more humid air mass establishes. Depending on how much sunshine we get, we could push deep into the 70s Thursday. The next cold front will hit Thursday afternoon or evening. It should not carry much, if any moisture with it, but it will lead to a sharp drop in humidity, a wind shift, and cooling temperatures.
Friday
By Friday morning, temperatures will have dropped into the 40s across most of the area.
Friday looks like a delightful day with highs warming into the low to mid-60s.
Weekend and next week
Onshore flow resumes Friday night, and we’re going to warm up big time heading into next week. Highs will push well into the 70s on Saturday and perhaps the 80s on Sunday. And from there, it doesn’t change a whole lot next week. Here’s a chart that shows each day’s record high temperature, as well as a forecast high temperature range from various operational and ensemble model guidance.
| Date | Record High | Current forecast high range |
| Saturday 12/20 | 81° (1921) | 77-80° |
| Sunday 12/21 | 82° (2010) | 78-82° |
| Monday 12/22 | 81° (2017) | 72-81° |
| Tuesday 12/23 | 81° (2020) | 76-81° |
| Wednesday 12/24 | 82° (1955) | 78-83° |
| Thursday 12/25 | 83° (2015) | 79-84° |
| Friday 12/26 | 84° (2016) | 78-83° |
The wild card day right now looks like Monday, which could see a brief nudge of cooler air before temps surge again. Our next shot at a meaningful cold front may not be until next weekend or later. But the takeaway is that record highs are very much in play every day between Saturday and next Friday, with perhaps the exception of Monday. Stay tuned.
