There are a butload of them...

Here's just a few I'm currently analyzing &/or you've already seen that produced a decent amount of wintry weather east of the mountains. There are probably a few more I'm missing here but yea there's a lot... I threw in the RAH Past Events archive events to make things a little more convenient if you're trying to come up w/ a list of dates
March 1 2015 (I've analyzed this storm, but it's not listed in RAH Past Events archive)
March 17-18 2014 (RAH Past Events)
March 6-7 2014 (RAH Past Events)
March 3-4 2014 (RAH Past Events)
March 28 2011 (RAH Past Events)
March 2-3 2010 (RAH Past Events)
March 1-2 2009 (RAH Past Events)
March 16-17 2005 (RAH Past Events)
March 30 2003 (RAH Past Events)
March 21 2001 (RAH Past Events)
March 12-14 1993 (RAH Past Events)
March 24-25 1983 (RAH Past Events)
March 22-23 1981 (RAH Past Events)
March 1-3 1980 (RAH Past events)
March 1-3 1978
March 25-26 1971
February 28-March 2 1969
March 16 1960
March 11-12 1960
March 9-10 1960
March 2-4 1960
March 26-28 1947
March 2-3 1942
March 13-14 1941
March 24-25 1940
March 10-11 1934
March 1-3 1927
March 13-14 1926
March 10-12 1926
March 30-31 1915
March 11-12 1914
March 24 1896
March 13 1896


In total, since 1895 I have 140 March storms lined up, a majority of them are light-moderate events confined to the mountains only, but there are plenty of legit ones over the Piedmont and coastal plain.

You can add March 20-21 1914 and March 22-23 1914 to this list as well. So yeah, 3 winter storms within ~ 10 days in mid-late March hit central NC in March 1914...

I would be shocked if that snow fell during the afternoon with a mid April Sun angle. I'm guessing it had to be a night or early morning event

Yeah, the overall setup is very strange... 1000-500 thicknesses were in excess of 560-565 decameters, there was no evidence of a coastal low or even a frontal wave, we actually had an area of low pressure over the Great Lakes as the snow was occurring in far eastern NC, and it was one of those cases (which usually don't work out) where cold air was chasing moisture... This event in Apr 1989 defies most canonical winter storm logic in central and eastern NC.

Didn't cross-check dates with Webber's post but I have the following for 1"+ RDU snows for March:
3,1,09
3,24,83
3,1,80
3,2,78
3,25,74
3,25,72
3,26,71
3,1,69
3,6,62
3,2,60
3,9,60
3,15,52
3,27,47
n=13 image below is n=12 doesn't include 1947 event. After all is said and done, large events >=1" for RDU are beyond rare. With the winter we're having, I can almost guarantee we won't have one.

Dang, can't believe I missed 1952...
After March 1927, this one from March 1940 is my next favorite march storm. Rare RDU bullseye w/ 6-7" of snow on almost the exact same date as the more famous March 1983 storm

goofy better not do this to me, unfortunately this is a time in which I hope the long range cold doesn't verify, if it does buh bye local free.
 
Transient cold shot at best. Certainly no winter weather. Very doubtful this March. Meh.
