Thanks Peter! Previously I used to use the map link you sent. But the one I sent was colorful so I fell in love with this windmap. It is amazing how sharp is the demarcation in both versions. I thought it was a front, but as you mention I too have never seen anything so clearly dividing the country. I think it is an unusual front.
I would keep watch to see how it changes over time! I am always fascinated by the wind energy!

As a Meteorology instructor, I've often seen wind map sites where cooler, drier, polar air from the north/northwest meets warmer, moister air from the southeast (a "front") but have never seen it depicted like the one you've sent. My best guess is that it IS a frontal boundary between the cooler Canadian Air and the warmer, more moist Gulf air............a classic cold front. See this site below for future use. In fact, it is now showing such a frontal boundary (at 12:12 p.m. on the 27th.) http://hint.fm/wind/ Hope this helps.

Is this pertaining to the way the front is moving? I don't think there is any physical barrier such as mountain range or am I wrong? https://www.flickr.com/photos/91426175@N00/23377535704/in/dateposted-public/ https://www.flickr.com/photos/91426175@N00/23710051640/in/dateposted-public/ Thanks in advance.
