Good Morning! The Big Heat Dome has expanded eastward. There are various heat alerts from California to Florida. We are under a Heat Advisory through Thursday. Heat Index as high as 108, if not higher in a couple of spots. Rain chances, while not zero, are very low today and Thursday. By Friday, the upper high starts to break down a bit. Scattered random storms will return. Storms become much more numerous over the weekend, as high temperatures come down to the lower 90’s. Close to normal. Here’s my brief Forecast discussion.
