Stovepipe

The rates really do drop the temps.  Went from 40 to 37 in 20 minutes or so.

I’ve got heavy sleet now. Sounds like a hail storm

Exactly, I've not heard that against my windows in a long time.  

Holy cow I'm all the sudden oscillating between a moderate rain/sleet mix and absolutely ripping sleet!  40T/33D

Heavy rates out that way..Sparta reporting 1/2" in 15 mins

Has anyone checked on Holston?

I headed out to get smokes beer or should I just call 911.

If you're running low, I say call em.  They haven't explicitly stated that that is not an emergency this time!

02z HRRR:

The folks at MRX are way more intelligent than I am when it comes to weather, so who am I to question this.  But modeling be damned, I'm in for rain then more rain *possibly* mixed with snow after 5am.

6z is 1am currently. 2 when we spring forward. So you don't have to stay up as late as you thought!

Wouldn’t that be the case every time it ran though? Or are you saying it actually went from 2am to 1am (example)?


.

Went from 3am to 2am over me from what I can tell.  7z to 6z.

I know we are just nitpicking the details, because that's what we do, but latest HRRR shows the change over happening an hour sooner than previous run, at least for central valley.

850 temp appears to be looking good as of 0z.  Thanks for the link John.

I have a few wet flakes mixing in. 

I saw an mping snow ob on the state line.  Was wondering if you were getting something or if the ob was at Lookout Mountain.

Radar looking healthy for Crossville.  Any obs?

First round of precip looks like it is going to pass south of me.

 

850s look a little colder than the NAM forecast. 

Where's a good place to find current 850 temps?  This has everything under the sun except that apparently:  https://www.spc.noaa.gov/exper/mesoanalysis/new/viewsector.php?sector=20#

HRRR has the change over time at 3am for Knox county.  Trying to decide if I should stay up or set an alarm.  I gotta see my flakes!

Went out to change the batteries in one of my weather station sensors and found that all my snow hadn't melted off . My grandma would always say it was sticking around for the next one to visit. 

Dang it John, you canceling your trip screwed up the weather forecast.  And now you won't even be able to get decent reception to watch the game buried under all that snow.

Worth noting that the 12z Candian ensemble has shown a noticeable uptick for the entire forum area regarding snow accumulations for the entire run.  Not used to seeing it so robust.  Some of you might be wondering about maps.  It is not a tease.  Been out of memory for about two years.  Seriously been contemplating getting a new account here just so I can have more map space!  LOL...kidding, not kidding.  CG2 might be in my future.

Interesting. I think for official measurements you are supposed to use a snowboard and sweep it clean every six hours. I've used a snowboard for several years now and it can vary quite a bit from old school ground measurements. If the ground is frozen solid, you'll get more with a ground measurement. If its warm and/or wet, you get significantly more on the snowboard. 

Here's Iowa State's discussion of compaction.  Pretty interesting and it just adds more value to their awesome meteogram page.  I have it up in a browser tab 24/7.

That Upper Cumberland tho.
