Quick advisory event that isn't forecasted?
I think it was MLK weekend in 2009 we had something like that...it was the day after a larger event. I remember models had almost nothing and then radar starts exploding to the south in a very meridional flow like we have currently, and Ekster walks into the BOX office and says "shit, I need to hoist advisories for 3-5"....."
It worked out too, I think i had a quick 4 inches that evening.
