From now on, for the convenience of mobile users, I’m going to begin each post with a brief summary: Houston will have several pleasant fall days before a slight chance of rain returns on Sunday. Strong storms are possible on Monday and Tuesday ahead of significant front.
After 0.1 to 0.5 inches of rain fell across most of the Houston area on Wednesday night showers are moving out of the area, and being replaced by much drier air. Highs climbed into the mid-80s for much of Houston on Wednesday, and temperatures for now through Saturday will feel much cooler, in the upper 60s to about 70 degrees. Nighttime temperatures will also feel great, in the low 50s. Expect partly sunny days.
Saturday should be the nicest weekend day in several weeks.
After a cool start in the low 50s, we’ll begin to see a more southerly flow later on Sunday which should increase humidity levels and will bring a chance of rain back into the area. I don’t have a great handle on conditions for Sunday, but my guess is that most areas won’t see significant rain. Highs likely will be around 70 degrees.
This is when the forecast gets more interesting. At this time a very potent upper-level low pressure system should move into Texas, bringing lift and unstable air. The system can be seen prominently in this map of the mid-levels of the atmosphere on Tuesday.
What exactly this means for Houston on Monday and Tuesday isn’t yet clear. But there’s the potential for several inches of rain, severe thunderstorms and possibly even isolated tornadoes. Over the next couple of days the details of this forecast should come into better focus, but for now it’s just safe to say parts of Texas, including Houston, will face the threat of severe weather early next week.
