Looking Even Further Back

Here are the maps from last year's big snow on March 1st and 2nd where the metro received roughly 6 to 10" of snow- this will help to put things in perspective. Notice the rigorous upper low in the south (moisture source and lift) merging forces with the trough to the north (which provided the cold air). This system started as rain, then switched to heavy snow. You can find these maps at the folowing link:
