Something may be happening - to our north



But I can't find any good surface forecasts for areas far enough north to make sense of it!


I first noticed that weather.ca shows generally north winds for Burlington for several days in a row, starting tomorrow..

Then I checked out the HPC medium range forecast and saw those isoabrs flowing from Labrador down into southern Ontario..

see here:
HPC - CONUS view forecast for 4 days from now...



I don't really know what to make of it, but it holds on for a few days in a row... And doesn't seem to be 100% due to any specific powerful storms...

But I do know it looks odd, and we rarely get 4-5 days in a row of north winds (usually NW turning W before then for 2-3 days) or NE turning some other crazy direction after 1-3 days...

And not only is it sustained, but it comes from great distances.. This seems to be a majorly important factor in vagrant birds based on my personal observations.. Winds in Moosonee should be north every single one of those days as well...

So what's the dilly?

I'm not exactly going into red alert, but I think it may pay off to focus a bit more attention on those birds in the Feb 28 - Mar 3rd time frame for northern goodies like Gyrfalcon or Eiders ... Or maybe even something like an Ivory Gull (one of my most wanted ON birds)..

The only thing that may be lacking is a major weather event tied to it... For fun check out these weather maps from 2010 in February -







Above is a 3 day stretch... Note how around the 13th the Isobars connect from Labrador right into southern Ontario for a few days...

Also note than an Ivory Gull was found at Cherry Beach in Toronto on Feb 15th (last map)..


Also note that the IVGU event was the same I experienced in Newfoundland where I saw 116 Ivory Gulls in a 6 days strech..

Also note that the event was created by a 969mb mega-storm over NL - something that this event does not have...


So what'll happen?! We'll have to wait and see if anything at all...

  1. This weather is the result of the storm that's currently over the west-central US. It'll hit Ontario tomorrow and hang around into Wednesday and Thursday depending on where you are in the province. The winds are more easterly - coming in from the Atlantic coastal states - than north-easterly for the next couple days I think, they only really start coming in from the NE once the storm gets past us and moves out to sea. The image you provided shows that well.
