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.

We have not had much sun this week and today will be no different. Rain chances increase late tonight with around 0.20" possible for most areas. We should finally see the sun return tomorrow through Monday with afternoon high temperatures near average at around 50 degrees. Our next rain chances increase by Tuesday late day into Wednesday. Wednesday should be our one well above average temperature day with highs reaching near 60 degrees! We turn sharply cooler by Thanksgiving Day.

After a frosty start this morning we will see a mostly cloudy day with temperatures this afternoon a few degrees cooler than normal for late November. Tomorrow we should see above normal temperatures but with rain arriving tomorrow night. The sun returns for the weekend with temperatures not too far from normal. We look to warm to well above normal by the day before Thanksgiving before the pattern change to colder takes hold by Turkey Day weekend.

A little below normal for Western Chester County PA where average is 35 inches and Eastern Chester County which averages closer to 32" of snow per season.

We saw a pretty evenly distributed amount of rain overnight with most spots receiving between 0.30" to 0.35" of rain. Today’s temperatures will remain below normal in the middle 40's with mostly cloudy skies. We stay mainly cloudy and chilly through tomorrow before we warm to above normal on Friday and not too far from normal temperatures to start Thanksgiving week. From this distance Turkey Day looks to be warmer than normal but that will likely change to a colder than normal pattern during Thanksgiving Weekend and as we move toward December. Our next chance of rain looks to it will arrive Friday night into Saturday morning.
