Discussion
The frontal system that edged off the east coast early yesterday has stalled-out and it will act as a conduit for tropical moisture to ride up along during the next 24 hours or so. As a result, there will be occasional rain today, tonight and on Saturday and strong thunderstorms are possible along the way. Many area lawns welcomed beneficial rainfall on Wednesday night from strong thunderstorm activity and there can be an additional couple of inches of rain during the next 24 hours. In fact, as much as 3 or 4 inches of rain is on the table for some spots given this overall setup and flash flooding may become a concern. The threat of rain will diminish on Sunday and temperatures will climb noticeably with highs likely in the low-to-middle 90’s. It stays hot in the Monday-to-Wednesday time period with afternoon temperatures well up in the 90’s on each of those days. Looking ahead, the upcoming heat wave will likely come to an end by Thursday with the mid-week passage of a cool front.
