We're entering the first of the semi-annual unsettled weather periods, albeit a bit late. The first unsettled period happens around March or April, as cold winter transitions to warmer summer, and the second one happens around October or November, as the fronts battle back southward and summer cools to winter.
This is why the old adage goes, "March comes in like a lion and out like a lamb," but the particularly strong cold polar air has been able to keep the transitional warm southern air from making its way up to us for later in the season than usual. Normally by March the warm air is pushing up against the cold air and fighting it out over the Great Lakes, and as the month goes on the cold weakens and the warm strengthens and has made its way to Canada by April. Not this year.
The old stalwart of aviation weather sources, the unsurprisingly-named aviationweather.gov, rolled out a new look yesterday. While checking out the changes, I see that the weather this year still isn't done with the surprises. Check out this prog panel:
