As we head into Friday morning, we will see cloud cover building in overnight.  We expect to see showers from 10am to noon. Overcast skies will remain after the rain clears out.  Cloud cover will keep our temperatures low into Saturday.  Saturday morning we will see that cloud cover start to break up as we start to see partly sunny skies for the rest of the weekend.

Technical Discussion (The nerdy stuff we are discussing in class!)
There is an upper level jet max that will influence the area through most of the weekend. An upper level trough remains through Saturday morning that provides some upper level divergence that will contribute to our next precipitation chance on Friday morning. This upper level divergence paired with low level moisture convergence, in addition to moderate vorticity at the 500mb level will help in aiding the cold rain that we will experience Friday morning. After the precipitation moves out of the area, there will be a temporary drying out at the surface.There is some warm air advection ahead of the upper level trough and lower level ridge. This warm air advection will have little effect on our high temperature's for Friday as we will see high's around 20 degrees cooler than is average for this time of year. As the high pressure system moves into the area, winds out of the south will help moderate our temperatures for Saturday, but we will still remain slightly cooler than the seasonal average. With this slight warming trend and mostly cloudy skies there will be an increase in surface moisture. Clouds will remain through most of the weekend with the next cold front moving into the area Sunday.
