NWS Sterling for Sunday rain event and 6Z GFS.
A slow moving compact upper low is set to push across the Upper
Great Lakes on Sunday before crossing through New England on Monday.
The associated frontal system brings the next shot for widespread
rainfall on Sunday. It should certainly be a welcome sight given the
lengthy period of dry weather and increasing drought conditions over
portions of the area. Periods of rain are likely within the warm
advection regime with total amounts expected in the 0.25 to 0.50
inch range, locally higher over the Alleghenies. Overcast skies will
be the norm on Sunday, accompanied by highs fairly close to early
November averages. That is, forecast highs in the mid 50s to low
60s. Any shower activity likely comes to an end by midday Monday
behind the exiting cold front
