8/29 – Payton’s Tuesday Afternoon Forecast
Flash Flood Watch for the area until Thursday night. Tropical Storm Harvey continues to meander off the upper Texas Coast this morning, and will likely continue to do so through the day and even into tonight. With this in mind, expect to see several bands of locally heavy rainfall develop over Southwest Louisiana and then propagate eastward across the entire forecast area throughout today and tonight. The rain bands will tend to be strongest south of the Interstate 10 corridor, with the possibility for rainfall totals of 2 to 3 inches in this area for today. Temperatures will remain cooler than average through the day due to the rainfall and cloud cover with highs only rising into the upper 70s and lower 80s. Tonight, low temperatures will be close to average with little overall diurnal range due to the extensive cloud cover in place.
Heading into tomorrow, the model guidance is decent agreement on the Tropical Storm finally pushing north-northeast and making landfall somewhere near the Texas and Louisiana border. The tropical system will continue to push inland towards northern Louisiana and Arkansas on Thursday. Rain will continue to affect the viewing area through the workweek and into and through the Labor Day weekend. Through the end of this week we could pick up between 5-10 inches of rain.
