Good evening
Its been a beautiful day today with highs in the 60's to near 70 in some locations and it felt great...but I like to think of this as the calm before the storm. Mid to late December is climatalogically a favorable time for cold and snow around here and when it gets this warm in December you know big changes are coming. There are rumors flying around of some possible snow around Christmas and thats just what they are at this point..rumors!! With that said the pattern is starting to look more favorable after Dec 20th and it is possible that a major pattern changing storm will occur with possible severe wx. I am talking about the storm around the 20th...
I think a STRONG lakes cutter with possible severe wx along a nice cold front that it will eventually push into the gulf of mexico around the 20th where another low pressure system MAY form along that boundary and ride up it in a path similar to a Miller A...of course this will need great timing and all but the possibility seems to be there. These two systems may be enough to dislodge the PV feature from eastern Canada and Greenalnd long enough where higher heights would then be able to form and in theory high lattitude blocking could then initiate in the NAO region near the new year. At least thats my take on the long range ensembles and teleconnections and any help from the PNA might speed this process up.
