The cold and grey conditions that have defined the last Saturday in September will stick around long enough to characterize the last Sunday in September as well.
In addition to the cold temperatures, mid-level moisture over-running the cool surface temperatures brings the potential for rainfall to the region.
Those showers will build in from the north over the late hours Saturday into Sunday morning.
The cold temperatures on Sunday morning will bring chances of some snowfall into the picture.
Accumulations are likely limited to colder surfaces like grass and should not stick around through the course of the day.
Sunday high temperatures will be the coldest of the forecast period, right around 40 degrees.
Late in the day Sunday we will see a shift to a southwest flow that clears the clouds and rain out from west to east and sets us up for a much more pleasant fall day on Monday.
