RaleighWx Winter Forecast 2014-15

Great job!  Thanks for posting.  What were the winters like for those top analog years you referenced? 

 

2009-10

2002-03

1958-59

 

1) Allan, very nice job of explaining things and quite believable.

2) KATL:

-2009-10 very cold (over 4 below normal and 9th coldest on record) (coldest since 1977-8) with 5.3" of SN/IP, which is 265% of the normal; one of the top winters ever in terms of combo of cold and SN

-2002-3: slightly below normal temperatures (~1 below longterm average) with T of SN/IP but got a moderate ZR

-1958-9: near longterm average for temp.'s and 2.4" of SN/IP, which is 120% of normal

 

Averaged together, they give KATL ~ 2 below normal and 2.6" of SN/IP, which is ~130% of normal.

I just checked for KRDU for the three Allan main analogs (SN/IP includes March as I did for KATL):

 

-2009-10: 3.2 colder than normal with 8.0" SN/IP

-2002-03: 2.5 colder than normal with 7.4" of SN/IP and a major ZR

-1958-59: 2.2 colder than normal with a whopping 13.5" of SN/IP and a moderate ZR

 

 So, at KRDU, the three winters averaged together were 2.6 colder than normal and had 9.6" of SN/IP as well as moderate to major ZR in two of the three. What is the very longterm based normal SN/IP at KRDU? I thought I read that it is at least ~6-6.5" and possibly pushing 7". So, I'm estimating that these three years gave RDU ~150% of longterm normal SN/IP along with ZR in 2 of the 3. These aren't far from KATL's ~2 colder than normal and ~130% of normal SN/IP. It all looks promising!

wow, great write up (and not just because of the magic words "cold" and "snow") very thorough and well put together - this took a lot of time. thanks for posting it

 

it also reminds me just how smart and how much weather knowledge many of our se posters have (qualities that sadly i do not possess lol)

Very nice job Allan and very close to my earlier prediction of 3-5F below normal and 150-200% of normal for snowfall. I would add that a MUCH colder/snowier winter than even what we think here is very possible if things break out like the early indicators seem to point to. Time will tell as usual

This would be an all-time record-breaking winter, so I am doubtful the results will look like your maps, but I also doubt we would torch or be neutral most of the winter either.

You? doubting? No way...I don't believe it. :lmao:

 

Great write up Allan. Hope it verifies, lots of mets calling for the same. Fingers crossed... :weenie:
