Terpeast Posted 11 hours ago Share Posted 11 hours ago Time for a December thread. GEFS/GEPS starting to show a potential coastal Dec 5-7 time frame with cold still hanging around. I should add that the canadian is more aggressive with the signal that time frame, the gefs or eps not so much. 3 Link to comment Share on other sites More sharing options...

WxUSAF Posted 7 hours ago Share Posted 7 hours ago 1989 is not remembered fondly around here because we missed some big storms north and south. But there was some snow and it was damn cold. Could have been pretty epic with subtle changes. Let’s just hope we don’t get January-February 1990… 2 Link to comment Share on other sites More sharing options...
JVscotch Posted 7 hours ago Share Posted 7 hours ago My gut says we don’t. 1988-1989 was a strong La’Niña vs last year’s El Niño. Last year didn’t get a chance to really do its magic but these shifts with the La’Nina to be closer to neutral, the anomalies beneath equatorial surface and the interesting MJO activity earlier, I think we are just getting started. I doubt wall-to-wall cold but the “best case scenario” that this winter had, even though was a lower percentage chance when starting the month, looks to be occurring hopefully. Will need to monitor the patterns and trends to see if cold keeps winning out and how some of these storms behave over the next few weeks. Link to comment Share on other sites More sharing options...

I'm hoping for a repeat but without you guys getting shafted, and also minus the tropical Jan/Feb. Link to comment Share on other sites More sharing options...
brooklynwx99 Posted 4 hours ago Share Posted 4 hours ago the timeframe around the 5th looks conducive for something bigger regionwide... anomalous 50/50, a decaying block over the Davis Strait, and persistent cross-polar flow. combine with an active STJ for split flow and there's a lot to like here 17 1 1 1 Link to comment Share on other sites More sharing options...
