8/5 – Rob’s “Lower Humidity” Thursday Morning Forecast

Today and Friday, the lingering frontal boundary will continue to move southward into the open Gulf waters. Upper level high-pressure will build in on Thursday followed by a short wave upper level weakness moving through Friday overnight. Overall rain chances will be low the next few days. Northerly surface winds today will help dry weather to persist and enhance subsidence. Some enhanced rain chances along the coastal areas and marine areas will be possible Friday late afternoon and evening. Southerly surface winds Friday will help to enhance warm air advection and lifting in the environment. The main impacts from these showers and storms Friday afternoon and evening will be gusty winds, frequent lightning and locally heavy rainfall. High temperatures will be fairly close to normal over the next few days thanks to the lower humidity values, so that will be a nice change from the hot temperatures we experienced last week.

Saturday and Sunday, a lingering boundary moves off the east coast will cause enhanced rain chances, mainly during the afternoon hours. Southerly surface winds will help to enhance warm air and moisture advection and lifting in the environment. Given the parameters that are expected based on the models, there will be the potential for locally heavy rainfall on Saturday and Sunday inside thunderstorm development similar to what we have experienced much of the summer so far. The main time frame right now is primarily during the afternoon hours. Monday and Tuesday, the summertime pattern returns to dominate the region. Scattered showers and storms will be possible, mainly during the afternoon hours both days.
