Hi Meena. 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. Pete Sar
