MR.SNOWMIZER Posted January 31, 2014 Report Share Posted January 31, 2014 If the trend continues with the gfs this has huge overrunning potential. But no torch and more chances for snow later on.

Skagit Weather Posted January 31, 2014 Report Share Posted January 31, 2014 I don't care if the GFS is off its rockers, it is one of the first cold and wet model runs, even in the long range for quite a while and it looks beautiful.

weatherfan2012 Posted January 31, 2014 Report Share Posted January 31, 2014 Well, for the first time this winter, the stratosphere is beginning to favor you guys.This is good news given the stratosphere has been dominating the macro-scale boundary conditions all winter.We have had absolutely zero ENSO/AAM inertia this winter..and a very weak, submissive MJO/RMM due to the incredibly anomalous QBO stress fields. The result of the said hemispheric shear regime has been persistent NPAC height rises. While the tropical forcings have been able to knock the ridging/wave breaking around, the general theme of rising heights somewhere around the NPAC continued given the momentum above the ferrel cell rifts.phil are you still thinking the AO is going to trend to be more negative the data seems as Geos pointed out seems to be going for a +AO mid february Quote Link to comment Share on other sites More sharing options...
Skagit Weather Posted January 31, 2014 Report Share Posted January 31, 2014 More like 3"I would say 10mm of rain is equal to 3-5" of snow, depending of course on temperature. Don't we usually go with the 1" of rain is 10" of snow conversion with temperatures 30-32F? 10mm is .39" of rain so it equals about 4 inches of snow.
