12/11 – Rob’s “Gloomy/Wet Weekend” Afternoon Forecast
Cloud coverage will increase this afternoon as the first in a series of fast moving fronts slide through the area. Given the lack of instability, shower activity will be main form of convection that occurs. If there are any thunderstorms, they will be very weak and very isolated. Rain will move in early Saturday morning with the first front, with clearing skies and cooler temperatures expected.The second boundary will dive through the region on Sunday.
Expect scattered showers and t-storm Sunday afternoon into Sunday night. A cooler airmass will move in behind this system, and temperatures are expected to fall back below normal for Monday. This break in the weather will be short-lived as another fast moving disturbance pushes out of the Rockies and across the Mississippi Valley Tuesday into Tuesday night. A surge of low level moisture from the central Gulf will support cloud and shower development from Tuesday afternoon through Tuesday night. Instability values will be limited, so thunderstorm development is not anticipated with this system.
