famartin Posted January 15, 2014 Share Posted January 15, 2014 These are based on the individual stats threads I made so all caveats I had listed in those apply here. Total 6"+ storms from 1944 to present: ABE 103, PHL 62, ACY 52 Interesting that PHL's total and ACY's total is so close while ABE is way way above, just goes to show that PHL is really more in the "South and East" category than the "North and West" category most of the time. Average of storms of 6" or greater from 1944 to present: ABE 9.7", PHL 10.4", ACY 9.6" As someone else mentioned, there is definitely a tendency towards having a whopper when PHL exceeds that crucial 6" mark. Total number of storms by site and month from 1944 to present: ABE: 1 October, 3 November, 17 December, 31 January, 30 February, 20 March, 1 April PHL: 0 October, 1 November, 13 December, 15 January, 21 February, 12 March, 0 April ACY: 0 October, 2 November, 9 December, 15 January, 18 February, 7 March, 1 April Interesting that there have been more 6" events in Allentown in January than February. Perhaps the tendency to shift the storm track to the favorable "benchmark" in February while in January its a bit closer. Just guessing.

KamuSnow Posted January 15, 2014 Share Posted January 15, 2014 Ray, that's great, thanks! More data to ruminate over....seeing the # of storms by month gives me insight into why I always thought February was the "snow month" around Philly. Amazing how well Allentown does in January comparatively, as you pointed out. Link to comment Share on other sites More sharing options...
windvane Posted January 16, 2014 Share Posted January 16, 2014 These are based on the individual stats threads I made so all caveats I had listed in those apply here. Total 6"+ storms from 1944 to present: ABE 103, PHL 62, ACY 52 Interesting that PHL's total and ACY's total is so close while ABE is way way above, just goes to show that PHL is really more in the "South and East" category than the "North and West" category most of the time. Average of storms of 6" or greater from 1944 to present: ABE 9.7", PHL 10.4", ACY 9.6" As someone else mentioned, there is definitely a tendency towards having a whopper when PHL exceeds that crucial 6" mark. Total number of storms by site and month from 1944 to present: ABE: 1 October, 3 November, 17 December, 31 January, 30 February, 20 March, 1 April PHL: 0 October, 1 November, 13 December, 15 January, 21 February, 12 March, 0 April ACY: 0 October, 2 November, 9 December, 15 January, 18 February, 7 March, 1 April Interesting that there have been more 6" events in Allentown in January than February. Perhaps the tendency to shift the storm track to the favorable "benchmark" in February while in January its a bit closer. Just guessing.

Nothing could be finer than having snow on the ground for 30+ days . What would also be neat is how many consecutive days that snow cover exceeded 12 inches on the ground. That means the piles in the parking lots did not melt for months. That is a winter---- not this hit and gone stuff in two days storms. That is why people freaked out on the last storm event because the ground was so cold that salt did not work and were not used to it Link to comment Share on other sites More sharing options...

That is why people freaked out on the last storm event because the ground was so cold that salt did not work and were not used to it weatherwise magazine in late 1973 had an artical about Philadelphia snowcover or lack of it in 1972-73...it had 1960-61 as the winter with the most snow cover...That gave me the idea for my NYC snow depth table...you can estimate looking at old records with no snow depth observations...time of year, temperature, daytime cloud cover,fog,rain go into the estimate...

yak Posted January 16, 2014 Share Posted January 16, 2014 Good stuff and really illustrates that the last 20 years so have been pretty kind to us. I wonder what the statistical probability would be, for instance, of Philly having 5 12 inch+ storms over two consecutive winters (09-10, 10-11)... or 4 15 inch+ storms over the same period... or 2 23+ inch storms in the same winter (09-10). Philadelphia set its all-time single storm record in 1983 by shattering a record from 1909. The 1983 record of 21.3 inches has been obliterated three times since and challenged one or two other times. Good times... Link to comment Share on other sites More sharing options...
Superstorm Posted January 16, 2014 Share Posted January 16, 2014 "The city, south and east" - I would say that is true for almost any major city on the east coast. Urban heat jungle makes sure of that. Link to comment Share on other sites More sharing options...
