9/21 – Rob Knight’s Final Friday of Summer Forecast

High pressure that brought stifling hot weather with limited convection is steadily moving further away from the region, now centered over the Carolinas. Isolated to scattered convection is moving inland from the coastal waters. As typical with the current environment, daytime heating will cutoff coastal region convection mid-morning before sparking inland thunderstorms.

The changes in the atmosphere should translate to much higher coverage today…on the order of 30 to 50%. Higher rain chances should be on the western side of the region as its further from the center of the upper ridge. The main threat with storms today will be locally heavy rainfall.

The forecast through this weekend and through early next week will basically be the same as today, albeit even higher precip chances. an approaching cold front will stall north of the I-20 corridor providing for daily rain chances in the 50-60% range with isolated nightly showers.
