Houston pushing record highs again, but some relief may come from showers moving south

Good afternoon. As expected, it’s an absolute burner out there today. Houston’s official weather station at Bush Intercontinental Airport has already reached 108 degrees as of 4 pm CT, which is 1 degree short of the city’s all-time heat record of 109 degrees. (We matched that record high on Thursday, you may recall). It’s now a race between temperatures and approaching rain showers.

In Friday’s forecast we mentioned the possibility of some late afternoon showers and thunderstorms developing on Sunday, associated with a weak boundary. We are now starting to see those showers forming north of the Houston metro area, and they should gradually move southward into the region throughout the evening hours. Areas where precipitation falls will see drops in temperature associated with rain-cooled air.

To set expectations, these showers will be very hit or miss. Lucky locations will pick up a few, quick tenths of an inch of rain, whereas other observers will look longingly as the dark clouds and see little, if any precipitation. At this point it looks like the stronger storms are more likely to develop north of Interstate 10, but areas all the way down to the coast at least have a puncher’s chance of seeing some shower activity.

We are entering a brief period where rain will be possible, essentially this evening through Tuesday morning, before a weak front brings some drier air and shuts the door on rain chances for awhile. We’ll have the full story on the forecast ahead in our post on Monday morning, but just wanted to jump in on a Sunday afternoon with a heads up about the rain chances this evening. Good luck out there!
