Houston has a messy forecast ahead so lets dive right in.
TODAY and THANKSGIVING
Warm air is now moving into the Houston area off the Gulf of Mexico, and we’ll see a couple of warm, gray days with highs in the upper 70s and muggy overnight lows only falling to around 70 degrees. Light rain will also be possible on Thanksgiving, although probably not more than a tenth of an inch of rain or two, and most likely during the afternoon or evening hours.
FRIDAY, SATURDAY and SUNDAY
Here’s where the mess begins. Over in the Pacific Ocean Hurricane Sandra is expected to move north into Mexico, and then toward the Big Bend area of Texas. This will pump a lot of moisture into the state and create conditions favorable for heavy rains.
But when you look at the rain accumulation totals through the weekend they appear to be highest over central, and especially northern Texas.

Sorry I’m late this morning with an update, but there was a surprise announcement this morning from Blue Origin, Jeff Bezos’ rocket company. They’ve successfully landed a rocket booster in West Texas and that’s a huge deal.
Anyway, on to the weather. After lows in the 40s this morning Houston is warming quickly and we’ll get into the low 70s today under partly to mostly sunny skies. Should be a great day.
WEDNESDAY and THANKSGIVING
We’ll continue to see warming conditions for the middle of this week as the onshore flow resumes and humidity levels rise. Highs on Wednesday and Thursday will likely climb to nearly 80 degrees. Rain will also be possible later on Thanksgiving, especially during the afternoon and evening hours, although I’d expect light rain at most.

Good morning. Well, it’s sure chilly out there, with lows in the mid-30s across most of Houston, and freezing temperatures along and north of Highway 105. The cold blast won’t last, however.
Under mostly sunny skies highs should warm into the 60s today. It should be really pleasant out by noon and during the entire afternoon. By this evening, with high pressure moving off to the east, winds will veer around to come out of the south. That will begin to increase moisture levels.
After another cool morning in the 40s on Tuesday, we’ll see highs jump into the 70s on Tuesday and Wednesday, with partly to mostly cloudy skies. Despite the increasing moisture levels, there will only be very slight rain chances due to a capping inversion in the atmosphere.
After a very warm first three weeks of November this year Houston plunged into the mid- to upper-30s on Sunday morning. For the first time this season it really felt like winter out. Highs today will only be in the mid-50s.
With clear skies and dry air, conditions tonight will favor even colder weather, with a freeze likely for northern parts of the metro area. Here’s where the National Weather Service believes that is most likely to occur:
