Meteorological winter (Dec-Feb, also what I generally consider to be winter) has come in with yet another record snowfall set the day before, and it looks like it will be rather cold this month if forecasts are correct (also refer to this composite I made in October). There will be another chance for snow on Wednesday as well, also of interest (not to be taken seriously, previously it had much warmer than normal temperatures) is what the GFS forecasts a week from now; can you say "cold"?

CPC temperature and precipitation outlooks for the next 6-10 and 8-14 days and for the month, as well as current CFS forecasts for temperature and precipitation:



Also, here is where 2008 currently stands among the wettest years on record (full years except for 2008), updated through December 1:

 1.   54.97   1982 
 2.   54.76   1993 
 3.   53.45   2008
 4.   51.65   1984  
 5.   50.83   1927   
 6.   50.73   1985  
 7.   50.31   1946 
 8.   49.28   1915 
 9.   49.20   1898  
10.   48.46   1876

At the current rate, we will break the record even if December has only 51% of normal precipitation, or 1.56 inches (including 0.04 inches so far) - which looks likely to occur (last month had 51% of normal precipitation).
