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.

Webb other than the obvious ones on the RAH past events page what do you have for March storms? Just wondering about dates

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.
 
Despite the fact it's supposed to be 86º at least two days down here next week and not backing off much afterwards, region-wide and for y'all a bit north - perhaps there is some "hope" on the horizon for a spring (not seeing any return to winter (yet) - but just not going into May and skipping March and April yet would be nice for y'all) - so here's something to hang some hope on -

I'm on board of the cold blast coming down, but not on board of a weather system coming along during the colder blast.
 
Don't want to get anyone busted for gambling on the internet, across state lines - but $$'s to ¢¢'s on this?

Definitely. I bet 100% we will have a freeze in March that will cause crop damage, be it 31 degrees or 22 degrees, it's going to happen. I am sure of it. The models have hinted at it, and all agree that we will be below normal, which opens the door to freezes.

My grad school roommate was from Enterprise AL, and his grandma used to chastise us - never plant your garden until after Good Friday ... there's wisdom from growing up in the woods (present company excluded) .... ;)

Well, actually , there is a huge difference between 31 and 22 degrees, when it comes to crop damage! 31 will cause some cosmetic damage to flowers and leaves that may have emerged, but the serious damage to crops/buds begins at 28 degrees and for atleast 4 hours at that temp, to be considered a " damaging freeze " in the agricultural world! If you want your petunias, and marigolds and other summer annuals or veggies to die, 31 will do the trick! And why on gods green earth, are tomato plants fire sale now in SC????? I guess they want you to buy them twice!? :(

Two interesting posts I ran across today - the 2nd is a gif which I can't figure out how to import - but the source is there if you're interested --

Yep a ton of trees and flowers have started blooming up here which I have never seen before mid to late march in my 10 years of living here. Unfortunately I've been saying that a lot this winter. But more unfortunate is that my temps on Saturday night are forecaste to drop below freezing for well over 6 ours and probably around 8. It looks like a low of 28-29 so I'm not sure how much damage that will do.
 
Prelim 18Z GFS maps (through day 7) suggest that the late 6-10 as well as into the 11-15 day period will probably come in colder and quite cold for much of the E US, possibly including the SE. Warning: watch at your own risk but by all means enjoy!
 
What a change between two runs on the GFS, well sheesh... Don't know what it's going to lead to but it's interesting to see.
