Here in the Northeast we are still dealing with the tail end of the Groundhog Day Storm-another week, another storm. This map posted yesterday on AccuWeather
nicely shows how big this storm was (or still is up here) with advisories in 43 states.
Each color represents a different type of advisory and they range from severe thunderstorms to blizzards, gales, floods, wind, wind chill, marine warnings, high surf, dense fog, air stagnation and my personal favorite, heavy freezing spray. I think that last one is along the lakes of northern Michigan but with so many colors it's tough to distinguish. The most common colors are the dark purply blue (winter storm), purply pink (blizzard), orange (wind chill) and the brown stuff in the south that I think is a wind advisory.
Despite the ugly projection, strange inclusion and exclusion of certain cities (especially in eastern Canada), and gratuitous topography that is easily mistaken for other weather patterns, the map still tells a pretty impressive story. Punxsutawney Phil says early spring-yeah, right. Have fun digging!
