A coastal storm will be developing in Eastern NC and then move north along the coast into west- central New England. This will produce a developing and expanding shield of rain that will move north. Some of which will be heavy. As this happens the atmosphere will also be cooling down. This means wet snow will break out and expand in coverage and intensity as one moves further north, esp. once entering NE PA.
There will be a sharp cutoff between rain/snow and those who get just clouds. A good approximation will be if you drew a line north and south through State College. East of that line it rains and snows, west of that line not so much, if at all.
For us? Clouds will increase tonight, as temps drop into the mid-20's then rebound to at least 30. With lots of clouds around for Sunday, the cold will be stubborn to leave. Temps will likely only rise into the mid-30s. (Where have we seen that before???). Rain should arrive in the mid-morning and continue lightly (heavy to our east towards Philly and Allentown) but then likely change over to some wet snow before ending in the late-afternoon.
I am not giving any accumulations. I don't think there will be enough to really matter and it will not be cold enough to create a major travel headache. HOWEVER, once one heads to Scranton on north into Eastern NY and VT the snow could get heavy for an increasing amount of time as one heads north late Sunday into Sunday night for a time.
The only reason I post on this is because it would take a very small change for this to dump several inches of snow on us. So the impact could be great. I DO NOT SEE THAT HAPPENING. Just wanted to let you know what I see. Certainly not boring.
