Yes, superstorm '93 was amazing indeed ! I remember windgusts to 70mph in the coastal plain of SC and temperatures plummeting to the low 30's by evening from near 50 in the morning with lite snow and flurries by evening. No accumulation here but it was followed by two very cold days here - highs in the mid to upper 30's and lows about 20-22 for the two consecutive nights in question following the storm. It was a big one - with high winds continuing here during the arctic outbreak behind the storm - NW winds gusts to 50mph still the next day with very cold wind chill values. We had fire in our fireplace plus the heat on !! Nobody was used to this in March ! Actually though, the best March storm I recall down here was March 2, 1980 as an arctic airmass discharged directly into the deep south and we received 4 inches of snow right on the coast and temps 24/15. This was A TOTAL MIRACLE what happened here ! Could this happen this March again ?? Well, I wouldn't count on it ! Although with the upcoming -NAO/AO it's something to possibly watch out for as for chances of major arctic outbreaks in first half of March. I guess the big question will be how far south the cold air (thickness values) will penetrate. This has been the delemna this whole winter so far. No severe arctic coldspells YET in the deep south, including Florida. I think the pattern this winter has been a little too progressive with insufficient blocking over Greenland. Plus the dreaded Pacific jet has been screaming onto the west coast from the Pacific over half the time this winter. And that's no good because it prevents blocking in the west and strong trough amplification downstream from the arctic. Hopefully we'll see one big wrap-up to close off the winter
