Most maps I have seen on this subject keep PA in the Mid Atlantic. The North East is limited to NY and up though some maps include part of NY as the MA.
I have not had time to look at dynamics or reasoning for the snow but I just viewed 4 models and all give 2" or more. Currently pegged to be a daytime thing so would indeed need rates as the temps are marginal.
Run the night shift. If round two did drop 3-5" it would gives schools fits tomorrow AM. I think all will be on two hour delay but that might be a second closed day for those not all virtual.
Go to the NE region view and start at hour 4 by going forward one panel at a time. There are what appears to be 6 slp's that come up the coast over the next 24-36 hours. Like a clown car. Really gets lower MD with heavy snow tomorrow evening.
Thanks. Hopefully she makes it safely. The HRRR changes us both to sleet for a period just before lunch. The orientation of the sleet line it sw to ne.
