Many of the lower valley locations across the area saw temperatures below zero overnight and this morning. The lowest was the 8.1 below zero at the Warwick DEOS site this is the 2nd coldest reading in station history behind only last January 22nd with a low of 9.1 below zero. The West Chester DEOS recorded it's coldest temperature in station history when the mercury fell to 1.9 degrees below zero this morning. Both stations have records back to 2012. We should see temps get close to freezing this afternoon and even milder tomorrow with highs near 40 degrees to melt some of the snow cover. The milder air is a one-day event as colder air moves back in tomorrow night setting the stage for what could be a major winter storm beginning as early as late Saturday or early Sunday morning. Snow may last into Monday morning before tapering off.

Always appreciate your professional views!! Thanks for your thoughts even though you are no longer in the area!!

NBM with an increase

6z vs 12z below

The latest European AI slipped south cutting snow totals almost in half across PA

My pleasure zen!!

Pretty stark differences between the first two 12z runs today. GFS says not a flake for this area.....ICON - significant snowstorm.

IMHO this is not really a Miller B type set up....more the bowling ball rolling along the baroclinic zone.....

Thanks Kevin!!

This morning's low here in East Nantmeal was 7.8 degrees our coldest reading since the 4.0-degree temperature last January 23rd. The coldest reading across the area was the 0.8 above zero at Warwick Township. We stay cold through tomorrow before a one day warming trend on Thursday gets our temperatures back to around 40 degrees. Lows by tomorrow morning will likely fall to near or below zero in the colder valley locations. We get colder again on Thursday night and stay in the freezer through the weekend. Snow looks to arrive with a potentially significant winter storm by late Saturday or early Sunday.

Yes I compiled multiple days into single events - not snow days. I would love to see your data! Thank you!

Below is the number of winter events or individual measurable snow/sleet events by season here in East Nantmeal Twp. with records back to 2003. I have also included seasonal snowfall totals. We have already had 10 winter events this season. The most was back in 2014-15 with 21 events with the least in 2019-20 with just 5 winter events.

Suspect the ratios if it happens would indeed be high so the Kuchy maps may be more accurate....

The 12z GFS did come north a bit from it's 6z run....let the north trend begin!!

The Canadian would certainly make snow birds happy...
