January 2016 Disco/Obs: A New Year, A New Pattern


Rjay

Recommended Posts

Currently we are exactly normal for Jan.   Next 8 days figure to be +6 by the GFSx so this would put us at +3 for the month by the morning of the 16th.

Not likely given the cold that comes Wed on of next week.  Mon and Tue are not that warm either

With the AO forecast to drop to -4.000 or below toward mid-January, I took a look at all January cases (1950-2015) during which the AO first reached -4.000 at January 15 +/- 10 days. I then looked at the number of days on which measurable snow fell during two periods, one beginning on the date when the AO reached -4.000 and ending 30 days later and the other with same starting point but ending 45 days later. I also looked at total snowfall during those periods.

 

Below are the data for New York City:

Wow....that's a pretty strong signal for a snowfall at some point in NYC

I agree. In addition, 1958, 1966, and 1979 all had KU snowstorms within the 30-days following the AO's drop to -4.000 or below and 1969 had one within 45 days. Put another way, 50% of the El Niño cases wound up having a KU snowstorm.

Seems the 12Z EURO took the suppressed GFS and suppressed it even further, so that none of EC benefits from the decent pattern.

Much colder run.

Havent seen the EPS yet which would be more reliable at this range BUT I would much rather have a potential large-scale phase job vort being suppressed as opposed to a cutter. It just seems that 9 out of 10 times when a cutter is progged the track never recovers to a favorable one for snow.

A photo from this morning:

Through 1 pm, Central Park had picked up 1.77" rain. That broke the daily precipitation record of 1.72", which was set in 1888. 1888 became known for a different storm in the NYC area that occurred in March.

 

So far, the high temperature in NYC is 58°. The daily record is 60°, which was set in 1876.
