07/23 – Rob Knight’s “Heavy Rain Possible” Thursday Morning Forecast

TD #8 is expected to continue westward, making landfall on the Texas coast Saturday. Main concerns here will be bands of heavy rainfall, and potential for minor coastal flooding. The moisture flow will be considerably high through Friday before diminishing somewhat on Saturday. While widespread rainfall totals are expected in the 1 to 2 inch range, isolated pockets of much higher totals are possible, particularly this afternoon into Friday.

Persistent east to southeast flow of 15 to 25 mph over the coastal waters is going to push water onto east and southeast facing coastlines during the high tide cycles tomorrow and Friday. Current indications are that tide levels will run about 1 to 2 feet above astronomical tide. Fortunately, tidal ranges will be decreasing as we get into the weekend. The additional cloud cover and precipitation will hold high temperatures mainly in the 80s through the weekend.

The area will remain in easterly flow into early next week, with occasional impulses moving across the northern Gulf. This is likely to produce periods of thunderstorms every day, each capable of producing heavy rainfall. No obvious dry day in the batch. Heaviest rainfall is expected to remain offshore, but will need to continue to monitor. This will hold temperatures below normal.
