A complex weather pattern involving weak disturbances tracking west across the Gulf, an influx of deep moisture, high pressure to our east and persistent low pressure to our south will contribute to a good chance of rain through early Wednesday.
In addition, persistent easterly winds gusting to 25 mph along the coast will likely lead to higher than normal tides, dangerous rip currents and offshore seas of 6-9 feet through Thursday.
Already, tides in Galveston are running about 1.4 feet above what would normally be expected and it is possible that some local advisories could be issued with this.
On another note, both Galveston Island with 26.67 inches of rain, and League City with 47.69 inches in August, had not only the wettest August ever, but also the wettest month ever observed at either location. By contrast, September was exceedingly dry with Galveston’s total of 0.32 of an inch, giving it the third-direst September ever.
League City fared a little better with 1.02 inches of rain during the month. But even that was still 6.15 inches less than what would be expected for the month.
So it is not unfair to say that some rain would be welcome this week.
Looking ahead, high pressure should build back into the area by the later part of this week, putting a lid on rain chances and ensuring warm, mostly sunny conditions for the weekend.
Meanwhile, a persistent area of low pressure in the Gulf of Mexico is being given a 20 percent chance of developing over the coming five days. The good news is that most models show high pressure keeping any system well away from Texas with some projecting a north to northeast path most likely.
