Cold could remain out west for next two weeks, by third week cold may pay us a visit




Ok the pattern upcoming for the next two weeks is quite simple.  Simply put, it remains a negative to neutral PNA, positive NAO and positive AO, this means cold air will continue to filter into the western Canada and Western US, while the eastern US and eastern Canada remain underneath a strong ridge of high pressure with southwesterly winds and warm temperatures.  By the end of October, this pattern may switch to more seasonal temperatures showing a cooling trend by the beginning of November.  the models show some semblance of a -AO/+PNA pattern emerging in the long range but the NAO remains positive or neutral at best.  Time will tell, but we will certainly run into a winter cold snap sometime in the future, perhaps near.
