Rainshadow Posted December 2, 2010 Author Share Posted December 2, 2010 yes...not a record though...there was a stretch from Oct 90-Apr 92 that was above normal...18 straight FTW. PHL also had the 10th warmest autumn on record, did you notice 1975 was on that list? Link to comment Share on other sites More sharing options...
Ger Posted December 2, 2010 Share Posted December 2, 2010 Can someone tell me what PHL recorded last year as its seasonal total? I know they dethroned the CPK 75.6 number from 95/96, but I don't know what the exact number is. Link to comment Share on other sites More sharing options...

phlwx Posted December 2, 2010 Share Posted December 2, 2010 PHL also had the 10th warmest autumn on record, did you notice 1975 was on that list? Too bad 2007 and 2001 were on there as well. Quite a mixed bag of years on the list! Link to comment Share on other sites More sharing options...

Since 1881-82 is before daily snowfall do you have a season total or estimate from old records on "how much for Philly" that winter? Link to comment Share on other sites More sharing options...

Don't know how much for Philly. I was looking at the 500mb anomalies for some of those winters vs the current pattern, it matched 1970-1 the closest.

Rainshadow Posted March 1, 2011 Author Share Posted March 1, 2011 I have 33.1F as preliminary final for the meteorological winter. Stats in the first post I have to check with CPC as to how they classify this nina. Now here is how ugly the analogs (winter average was 35.2F) worked here and throughout the country until February proving how a strongly negative NAO can trump the Pacific. WE ARE ABOUT TO CLOSE THE BOOKS ON A VERY HISTORICAL LA NINA WINTER WHICH REALLY WAS MORE LA MISSING IN ACTION WINTER AS FAR THE TROPICAL PACIFIC WAS CONCERNED. GIVE OR TAKE A TENTH, THE METEOROLOGICAL WINTER OF 2010-11 WILL AVERAGE 33.2 DEGREES IN PHILADELPHIA. THE CURRENT WINTER NORMAL IS 34.8 DEGREES. THIS WILL NOT BE THE COLDEST MODERATE OR STRONG LA NINA (WE ARE NEAR THE CLASSIFICATION BORDER) WINTER ON RECORD AS THAT HONOR REMAINS WITH 1892-3 AT 29.6 DEGREES. IF THE PHILADELPHIA AVERAGE IS 33.2 DEGREES, WE WILL TIE BE THE COLDEST MODERATE/STRONG LA NINA WINTER SINCE 1970-71. IF WE DIP DOWN ANOTHER TENTH, IT WILL BE THE COLDEST MODERATE/STRONG LA NINA WINTER SINCE 1942-3 WHICH WAS 32.3 DEGREES. WHAT IS ABSOLUTELY CERTAIN SINCE SNOWFALL RECORDS BEGAN IN 1884 IN PHILADELPHIA, THIS IS THE SNOWIEST MODERATE OR STRONG LA NINA SEASON ON RECORD AT 44.0 INCHES AND WE ARE STILL COUNTING. THIS BROKE THE PREVIOUS RECORD OF 39.6 INCHES SET IN 1916-17. THE SNOWIEST LA NINA OF ANY STRENGTH WAS 65.5 INCHES SET IN 1995-6. THIS WAS ALSO THE FIRST TIME IN ANY LA NINA STRENGTH SEASON THAT PHILADELPHIA RECORDED TWO TWELVE INCH OR GREATER SINGLE SNOWFALL EVENTS. THE LAST TWO SEASON SNOWFALL TOTAL OF 122.7 INCHES AND COUNTING IS ALSO A RECORD FOR CONSECUTIVE SEASONS. SINCE THE WINTER OF 1872-3, THERE HAVE BEEN 45 LA NINA WINTERS AND 17 HAVE REACHED MODERATE OR STRONG STRENGTH. AS TO WHY THE COLD, THE NORTH ATLANTIC OSCILLATION TELECONNECTION REMAINED STRONGLY NEGATIVE THROUGH THE FIRST HALF OF THE METEOROLOGICAL WINTER. THERE IS A POSITIVE CORRELATION BETWEEN THAT FEATURE AND COLD WINTERS IN THE NORTHEAST. FROM MID JANUARY THROUGH THE FIRST WEEK OF FEBRUARY, THE PACIFIC NORTH ATLANTIC TELECONNECTION INDEX TURNED POSITIVE WHICH MEANT RIDGING IN WESTERN NORTH AMERICA AND TROFFING IN THE EAST. THIS NOT ONLY KEPT THE COLDER THAN NORMAL WEATHER GOING, BUT ALSO INITIATED AN ACTIVE WEATHER PATTERN WHICH INCLUDED THE HEAVIEST SINGLE SNOWFALL EVENT IN PHILADELPHIA DURING THE WINTER AND THE LARGEST ICE STORM OF THE WINTER. ONLY DURING THE LAST THREE WEEKS HAS THE WEATHER PATTERN COME CLOSER TO A TYPICAL LA NINA WINTER PATTERN. AS TO WHY THE SNOW, THERE IS ABOUT A 2:1 RATIO OF BIG SNOWS IN PHILADELPHIA AND THE STATE OF THE NORTH ATLANTIC OSCILLATION, WITH THE MAJORITY OCCURRING WHEN IT WAS NEGATIVE. HEATHER ARCHAMBAULT HAS ALSO SHOWN THAT LARGER PRECIPITATION EVENTS OFTEN OCCUR CLOSE TO PATTERN CHANGING TIMES. WHILE THE NORTH ATLANTIC OSCILLATION REMAINED NEGATIVE IN LATE DECEMBER, IT WAS CLIMBING TOWARD NEUTRALITY DURING THE BOXING DAY BLIZZARD. IT WAS CHANGING FROM NEGATIVE TO POSITIVE DURING THE JANUARY 26TH-27TH THUNDERSNOW WINTER STORM. TIMING AND LOCATION NEVER HURT EITHER AS WE HAD TWO LOW PRESSURE SYSTEMS WITH NEARLY PERFECT STORM TRACKS. THE NORTH ATLANTIC OSCILLATION WILL SEE ITS RECORD BREAKING 16 CONSECUTIVE MONTHS OF NEGATIVE VALUES END THIS FEBRUARY. DECEMBER JANUARY - the opposite would have been quite accurate in the east.
