1/21-1/22 Winter Storm OBS Thread

[DeltaPilot]

I finished up with just shy of 1.5" Im calling it 1.3" here. Pretty morning but the roads last night and into this am were and still are a shitshow. Should get melting on all sun exposed surfaces cranking up any time now and improve the situation.

Im hearing the ATL airport and Delta Operations are a full on complex IROP causing massive delays and cancellations. Im sure every early go today needed de-icing and thats just fuel added to the fire. Word on the street is over 500 ground/ramp

personnel either called in sick or could not make it in. Will take a few days to smooth out, but its pretty bad.

Some melting and evaporation occurring.  Sad.

Only 26 out. But the sun is torching whatever little we have.

The snow line literally hugs I-85.

Sun starting to break out. Temp at 24.

Sounds good. I'm definitely a bit leary on your measurements, but at the very least got a half inch, so I'll pay up Maybe Sunday

 This was a very enjoyable and interesting winter storm of rare proportions here! I measured ~2.9” (mainly sleet…see image below) from a 12 hour long combo starting as sleet for couple of hours, ZR adding to base for a couple more hours, back to sleet (much more that lasted several hours), and then some snow during last few hours often mixed with sleet. And it is a very solid 2.9”! Temperatures during the bulk of it were in the upper 20s.

 That’s the most accumulation in this area since 12/1989. 1/2018 was ~2” of a combo.

 I estimate the sleet portion of the 2.9” was 2”, which would almost have to be the most sleet in the city from any storm in modern records (back to mid 1870s). 1/2018 had a good bit of sleet that lasted ~2 hours (including when mixed with snow), but it didn’t get over 0.5”. This was the 3rd most sleet I’ve ever seen behind only two ATL sleetstorms (2/1979, 1/1988).

 The ZR portion fortunately was much lower here than the ~0.45” in 1/2018. I’m guessing it was ~0.1” with no more than 0.05” of accretion. Thus, there were very few outages in SAV (only ~200). However, Glynn county (Brunswick) has a whopping ~28K outages, which is ~55%! Nearby Charlton county had a similar % out while Camden (~1/3) and McIntosh (~1/4) had fewer but still many out. So, extreme SE GA had by far the most ZR in the state, which was modeled well. I haven’t seen amounts yet.

 Total liquid equivalent precip was 0.71” at more inland SAV. Based on models calling for an avg of ~0.10” more in my area, I’m guessing ~0.80” for my place, which would be near the similarly impressive ~0.75” I got in 1/2018 (that one lasted ~7 hours). Had all of the precip been snow (which was not forecasted), perhaps I could have had up to 5” based on rough Kuchera type of considerations (nowhere near 10:1 with 850s borderline). Regardless, this 2.9” of a solid layer, if anything, will very likely melt more slowly than 5” of pure snow.

 After a low near 27, current temp has struggled to only 33. Thus melting of this rock solid accumulation has been very slow.

 

Edit: For me this was not only the Brick storm (thanks @Brick Tamland) but also the Tony @dsaurstorm due to sleet dominating! He would have loved it!

Edit #2: I brought inside 2 samples of the frozen precip that I had collected in 2 cylindrical cups to melt it and allow for an estimate of liquid equivalent. I did something similar in Jan of 2018 to estimate it for that winter storm. I plan to post about the results after this is completed. I’m roughly estimating 0.80” based on adding ~0.10” to KSAV’s 0.71”.

Congrats! That is the best sledding snow.

It truly is amazing how often I-85 is the cutoff.

Looks like Cordele had the biggest snowfall in GA with 9"  Didnt you say the record here was 3"?

 Congrats, holy cow on your amazing 9”, your snowstorm of the century! Who would have ever seen this coming this winter?

 The Cordele record is the 3.5” from the great Feb of 1973 snowstorm. That one gave this area 3.2”.

Good luck to everyone. We were supposed to get 7-9 inches and it looks like we may get a half inch.

Guess you got a bit more than a half inch eh?

[snowinnc]

Went outside right before I went to bed and measured 1.2” in Northern Wake County. Kids started sledding on the neighborhood hill early this morning, so they’re thrilled!

Many thanks for the stat's that you provided in the long range thread leading up to this.  It's been a great few past days to speculate and then watch it all play out.    Topped out at 2.1" here.

Did you buy dry ice?  Or risk it due to your trusting it would be ip/sn?  And looking ahead it looks like the pattern wants to bomb us with zr, so don't take those power packs back.

 When I learned about the difficulty in dealing with dry ice, I decided that wasn’t worthwhile. Also, no semi-reliable recent model had anything close to danger level of ZR for outages here. If they did, I would have gone with plan A of buying bags of ice. But I still charged up the 2 power packs just in case because why not since I had them. I have 30 days to return them.

 What are you referring to about pattern wanting to bomb of with ZR?
