TTR Weather Update for COLORADO, JACKSON, and WHARTON Counties from National Weather Service Houston/Galveston

No Comments Local News

A slow moving frontal boundary will move into northern parts of southeast Texas Saturday afternoon. It will eventually stall near the coast Sunday and then meander about the region through Tuesday. This feature combined with a series of upper-level disturbances moving overhead will provide chances of showers and thunderstorms through Tuesday.

Impacts
The majority of computer models are indicating that most locations should receive just beneficial rainfall through the weekend – generally less than 1.5 inches (and even less than that along the beaches). That being said, history has shown that slow moving or stalled boundaries like this during May can sometimes pose a localized heavy rainfall threat that we will need to keep an eye on for potential flash flooding.

Locations
We will begin focusing on areas generally north and northwest of Highway 59 Saturday evening through Sunday morning.  Beyond that, and through Tuesday, forecasts and hazards will be highly dependent where the surface boundary is situated. This likely will be too difficult to forecast with much accuracy beyond 12- 24 hours (and possibly earlier).

Bottom Line
There is considerable forecast uncertainty at this point.  So enjoy your weekend, but keep up with the latest weather forecasts.
