Blue Moon

Beginning to think the Tennessee Valley has an annual monsoon that begins in February. Curious to see if annual mean precipitation increases when the '91-'20 normals are released. Has our climate gotten slightly wetter? Would like to graph a trend from the early 20th century to today.

"Yay! Flooding, my favorite form of extreme weather" - nobody But hey, at least it isn't wildfires.

Good week for winter weather lovers down here. Recap for my area: Thu, Feb 11: Ice storm (still ice on trees as of Feb 20) Fri-Sat, 12-13: Freezing fog for more than 48 hours; temps remained below 0 deg. C Sun, 14: 0.5" of sleet in evening Mon, 15: 1.0" of sleet Tue, 16: 0.5" of dry snow Wed, 17: 3.5" of snow, 0.1" of sleet Thu, 18: 0.5" of snow

If I include the 1.5" of sleet in my annual total, I have 9.3" for the year. This winter has been a good one. Can't complain when you get above average these days. I'm 30 miles from Nashville, situated approximately 300' in elevation higher than KBNA. It's safe to assume my location should average slightly more than KBNA's annual snowfall- maybe by a half inch or so. If the 1981-2010 data at KBNA was 6.4" per year, let's assume the average in Primm Springs is 7.0" per year. It's been more rare in recent winters to surpass the average from the past, so my expectations for each winter are a bit lower. Therefore, this is my grading system for how well a certain winter did IMBY based on snowfall: F: Trace or no accumulation (example: 2004-2005) TOTAL FAILURE D: 1" or less (2011-2012) VERY DISAPPOINTING C-: 1-2" (2013-2014) FRUSTRATING C: 2-3" (2016-2017) LOUSY C+: 3-4" (2017-2018) MEH B-: 4-5" (2007-2008) SATISFACTORY B: 5-7" (2014-2015) DECENT B+: 7-10" (2009-2010) GOOD A-: 10-15" (2010-2011) GREAT A: 15-24" (1995-1996) EXCELLENT A+: 24" or greater (1976-1977) EPIC

Hey all, decided to repost what I shared on Tennesseewx.com. This is a brief analysis of the nation's seasonal snowfall (including images). Shows national snowcover as of January 1st, February 12th, and today. This week has been one for the record books for millions of people. https://tennesseewx.com/index.php/topic,4027.msg259012.html#msg259012

Didn't age well at all. Did exactly what the HRRR showed all day. As soon as I started b**chin', the snow started fallin'.

3" of new snow atop 1" of ice from Monday.

So glad the whole state is getting frozen precip. out of this. I'd like to see Chattanooga get something.

When the sun when down, the sleet changed to snow, and it started piling up. I have probably added 2" since 6pm. I have not taken a measurement though.

How could the models be so off? Goodness. I give up on ever being excited for snow here.

I've been getting nothing but light sleet. Everything if going wrong here if you like snow.

Looks like the radar at MEG already sees some moisture moving in- hopefully that raises the DP and we don't have a significant dry air issue by tomorrow afternoon.

Curious if that has shifted SE to account for the dry air on the northwestern edge of this one.

I will take the 15" of winter soup and cash out now before it dries up.

In the case study of Monday's storm IMBY, I have to say the NAM outperformed the HRRR. It had the correct solution a day in advance while the HRRR took some time to conform to it.
