8/15 – Brittany’s “Heat Advisory Ahead” Monday Evening Forecast

The main focus of the short term forecast will be the warmer temperatures heading into Tuesday and likely again Wednesday. It has been a while since we`ve had these warmer temperatures, since we`ve seen so much rain the past month or so.

Hot and drier conditions will subside by the end of the week as the surface high pressure yields to an approaching frontal boundary. The leading item to discuss in the extended period is the potential for excessive rainfall across our area on Thursday and continuing into Friday and Saturday as the boundary slows in its progression southward. Ingredients will be favorable for locally heavy rainfall and the potential for isolated flash flooding with ample moisture (PWATs between 2.1 to 2.3 inches) and more favorable forcing for ascent as a shortwave digs down into the lower Mississippi River Valley along the longwave trough axis over the US east coast.
