After a frosty start in spots, we should see sunny skies with temperatures not too far from normal for both today and tomorrow. Rain chances increase by Tuesday afternoon with some spots seeing the potential for up to 0.50" of rain before it ends on Tuesday night. Wednesday looks like our one warmer day before we turn back to well below normal temperatures for the Thanksgiving Holiday and weekend.

Well, I have completed some deep analysis across all of the Chester County and SE Berks County PA climate sites to see how often we have seen a White Christmas here in the western Philadelphia suburbs of Chester and SE Berks Counties. Now what is up for debate is what represents a White Christmas?? For purposes of this exercise, I am considering measurable snow on the ground (+0.2") on either December 24th or December 25th before midnight. Some interesting statistics of note. We have received Holiday Week snow during Christmas week (December 17th through 25th) in 77 of the 132 years or 58% of all Christmas seasons We experience a White Christmas somewhere in Chester/SE Berks Counties about 1 out of every 3 years or 34% of all years. We have received measurable snow on 29 Christmas Eve or Days (22%) 16 measurable snows on Christmas Eve 13 measurable snows on Christmas Day One inch or more snow was on the ground: 32 times on Christmas Eve (24%) 31 times on Christmas Day (23%) Our last White Christmas was last Christmas Eve Day when 0.5” fell at East Nantmeal and 0.4” at Octoraro Lake on December 24th. Below is the number of White Christmases by Decade including the partial decades of the 1890’s and our current decade the 2020’s.
