08/18 – Brantly’s “Hot and Humid” Wednesday Morning Forecast

 A typical summer time pattern is in store throughout the near term as upper level high pressure begins to build in over the region from the western Atlantic. At the same time, Fred continues to move northeast over the Appalachians as it slowly transitions into a non-tropical low over the central United States moves northeast into the Great Lakes Region.

By Thursday the upper level high will encompass much of the northern Gulf Coast, stretching all the way from Texas to the southeast coast of the US. Meanwhile, a surface high pressure begins tracking westward across the northern Gulf on Thursday evening, causing moisture levels to decrease offshore. Moisture will remain abundant inland, however, due to southwesterly flow. Scattered showers and storms can therefore be expected once again on Thursday with convection developing along the seabreeze.

Highs today and Thursday afternoons will be hot as they reach into the low to mid 90s. These temperatures in combination with the increased moisture will cause heat indices to soar into the 102-107 degree range. We will continue to monitor heat indices as these values are just below Heat Advisory criteria. Lows tonight are forecast to dip down into the lower to mid 70s inland with readings in the mid 70s to around 80 degrees along the immediate coast.
