A wee bit different take at the 850mb level between the GFS and European 12z....if GFS is right it rains up to MPO.

Maybe I sound weenie but I'll say it: When the Euro and GFS disagree on a storm like this, 9 times out of 10 the Euro will end up being correct

Insane difference for only 100 hrs out.

Torch. It’s the GFS/NAM/ICON vs. everyone else right now.

I heard some roaring and it wasn't the wind... it was this forum kicking into gear as something trackable emerges! 

Of course a concern would be the SSTs along the coast.

The 6z GFS verbatim wants to do a Miller A type thing, out of the Gulf and up the coast.

As an OBS, my low this morning was 30 and it's currently 34 with dp 23, so cold dry air out there (something that would have to moisten up if any rain has a chance here Sunday).

This morning was the coldest morning (26.1) here in East Nantmeal since last April 9th at 25.8. Warwick was the area cold spot at 22.1 degrees this morning. Sunny and chilly today with highs struggling to escape the 30's in the hills with low 40's in the valleys. Clouds increase tonight with some light snow or a mix of rain/snow arriving tomorrow morning before a quick change to plain rain. Monday looks sunny before snow arrives toward Tuesday morning. We should see a pretty steady transition from snow to rain from SE to NW across the area. The best chances for a small accumulation will be across far NW Chester County and into Berks and Lehigh counties. We keep temperatures well below normal all week with the coldest weather of the season arriving to close out the week. Temperatures on Friday may not even reach freezing for high temperatures.

Don’t look at the NAM…massive torch for everyone including the Poconos.

I’m writing it off as the NAM being the NAM. Just posted my first call on my page, I think the Lehigh Valley sees 1-3” followed by a wintry mix and rain.
