As you can see by looking at this image above you can see that the primary low is actually over the WVA/VA border. What this is doing is sending a dry slot right up thru PA which you are beginning to see if looking at radar.
Basically we have very weak reflection of a secondary low while the primary remains west and stronger.
What this means is on the previous map issued the eastern side of the area will be lucky if they see any precipitation turning to snow. From East central PA south and east it will probably end as rain and in the next couple hours. NE PA should be seeing snow now but also it should end within a couple hours. Central and Western PA is seeing snow now and western PA should continue to see snow longer cause they are NW of the primary area of low pressure..
We will watch the moisture to the west over W VA to see if that moves east but current thinking is that should pretty much weaken once the coastal does get going but it will generally not be in enough time for eastern PA the way it looks at the present time.
Keep this in the back of your mind as to how far west this actually has come once again because 2-3 days from now another system will be monitored which is suppose to go south and east of the region…
3:30 AM ..Some precipitation is moving towards the region from the west ..it should be very brief…it should be mainly in the form of rain from E Central PA south but it may change to snow before it tapers off…
