I guess it's easy to forget that not everyone appreciates the snow like us weanies.

Snowing extremely hard here in Dickson again! And the driveway that we just shoveled is getting covered again!

With the half inch recorded in Nashville with this system, we have now reached 7" on the season.  Normal by this point in the season is 6.6".  So, we are right on track of normal, if just a hair above it.

So far in February, 2.2" has been measured.  Normal at this point in February 2.1".

So, climatologically speaking, we are having a very normal winter as far as snow is concerned.

It just doesn't seem normal, since we've had so many underperforming years in the recent past.

Excellent point. I would like to find the annual snowfall for Scott County. MRX has it listed at 6" on its climate site, which is not correct. OHX has Jamestown listed at about 20" and Crossville at about 14". I think our norm in Oneida is somewhere in between those figures.

OTOH, if you base "normal" on a rolling 30-year average, most of those are still defined as being 1970-2000, correct? I wonder what it would be if the '70s were subtracted and the '00s were added in.

They may be talking last 10 years, while OHX is talking last 30

It would be a big drop.  I'm not exactly sure what span of years is used for the averages, or if it's the constant previous 30 years at any given point.

At any rate, here is a graph of the 30-year rolling average at Nashville from 1914-2007:



You can easily see the significant rise of snowfall during the 1960s and 1970s, followed by the decline during the 1990s and 2000s.

folks, the BIG DOG is lurking at the end of the month!

Perry County Schools may never get out this summer. They have now used up all of their snow days and are 4 days over. Monday was supposed to be a make up day well it snowed that out, now they was out today and their going to be out tomorrow. . . The kids love it now but when their in school the first of June they will be thinking 

[Cameron K.]

Oh my goodness. Now that is FTW. Thanks for posting it Crockett.

what's nashville's 10 year average snowfall? what baout the 30 year?
the same for temperatures?

  A few years ago, I performed a sine regression on the NOAA snowfall data for Nashville and posted the resulting formula on this forum (Cyclic Snowfall Averages thread January 2008).  For what its worth, the formula predicts average snowfall for Nashville should start rising after this year, reaching a peak of 12 inches around 2030.  The current average according to the formula is 5 inches.

Here is the formula for any  math nerds out there  

y = 4.159477sin[.106344 x -.789182] + 8.020243

(Time is measured from 1890.)

Yep.  Well, this year is definitely a start (even if areas all around us are having the winter of all winters, while we're just barely managing to possibly squeak by with a normal winter for the first time in years).
