Well, I'm going with the model that gave me, cash, and bubbler the winning prize of 0.2" for the entire event. I really can't get over the Euro hanging on while all others have abandoned ship...lol...get that? Meanwhile, I will enjoy the possibility of coming close to or maybe even exceeding my lowest temperature of this season tonight. Coldest minimum so far was -0.6 degrees back over the weekend. Currently I'm at 8.6 degrees and dropping. This is the earliest in the night I've reached single digits. So, my anticipation for morning is close to zero again or perhaps -1 or even -2. My amazing ice-encrusted 11-day old snowpack is still going strong at 2". I cannot see any grass yet (in my back yard, which faces north.) My small front yard only has a few spots left with more than a trace there. Fortunately, I have a large picture window facing out back which provides me with ample opportunities to be reminded that it is still winter, and we are very close to our climatological bottom for daily average temps. .

That's crazy. You're in the same snow band that I've been in for over 20 minutes and yet I have only virga. It must be the river effect.

Pretty sure MAG showed us a snow map yesterday for this next clipper and it showed the precip only barely making it to me and then nothing east of there unless you were mid sv or north. Laurels were the winner again with 3-4". It's funny, I feel like I'm reliving yesterday as the overcast moved in here pretty quickly after lunchtime and now it's just a dark gray, looking like snow. I don't think lanco sees anything more than flurries to a dusting at best.

My expectations were rather low on this one. The majority of the model runs leading up to this event pretty much kept me under 1". I ended up with 0.3" which was just enough to cover the sidewalks and my cul-de-sac street. The one thing i noticed while outside just now and near the one street light on my street was the incredible crystalline nature of the snow. It looked like a sea of diamonds sending up shimmering reflections of light. The other interesting thing was because the past several mornings have been near or below 10 degrees, the snow immediately began to stick and accumulate on those surfaces even though the temp was close to 34 leading into the clipper. Finally, it's now been 7 continuous days with snow cover, longest stretch of the winter and very likely to last throughout most of this upcoming week.

Flurries! Finally! Temp 32.7.

I think it's getting close to starting. Solid echoes are finally overhead. I can judge by temperatures that it is definitely snowing out in Newburg, which is about 25 miles west of me. Looks like there's pretty good intensity as well. Fingers crossed. Temp 32.9, dew point 21, wet bulb 29.

Me too! It's an hour later and still nothing. It's getting dark now so I can't enjoy it as much. (Not complaining. I still have a solid 2.5" icy base from last week).

Unreal on radar...snowing to my west, snowing to my east, and a bupkis (hi @Festus) sandwich here. Temp 34.0 dew point 20, wet bulb 29. I'm pretty sure there is enough cooling potential present to get back down below freezing IF the snow ever starts.

Well my prediction for my low overnight came true. I broke into the negative with a -0.6 degrees, which rounds to -1.0 officially. Solid snowpack definitely helped, even though it's only 2-3". It got the sleet/zr crust on top preserving it. My dog can walk on top of it without falling through. He only weighs 14 pounds. Temp has rebounded all the way up to 19 degrees on its way to close to 25 in a few hours. So, no snowmelt today.

Temp has been plummeting during the past hour, down 4 degrees to my low of the day, 9.3 degrees. I expect to be close to 8.5 before the day ends in 15 minutes. NWS forecast low for tonight is 5. Last night it was 2. I think I've got a shot close to zero. We'll see how close I come in the morning. Coldest minimum so far this season was 4.5 degrees earlier in the week. I just love having a nice snow cover going into a clear, calm night. Radiational cooling at its most efficient. Down to 9.1 as I post this.

Wow, yeah. That would shut just about everything down for a few days I would imagine, given the lack of snow removal equipment, etc.

I wonder if Charleston, SC has ever experienced a snowstorm of 24"+ in its record keeping history?

Looks like at 3:00 I am finally going to drop below 32.0 (I'm teetering between 32.0 and 31.8) and stay below there the rest of the day. I didn't warm up that much...only to 34. A check of some of the models that output surface temps shows that every one of them has busted low by several degrees. The HRRR seems to be way high on tomorrow night's lows, only dropping the MDT area, including me, to a low of +8F. Fortunately, I've got a nice, solid snow pack that still is close to 3" deep. That should help tremendously with radiational cooling tomorrow night. NWS has me at +2 for the low so I definitely have a shot at zero or a little below. Looks like that Euro chart from MAG shows me at around -3 or so.

Morning all. First look around this morning and I see all trees with a very light coating of white. Same for sidewalks but not the street. Last night around 9pm I got on here and said I had dropped to 29.1 degrees and was feeling pretty good about accumulation chances. Well that drop turned out to be a big tease as the temp started going back up again and by midnight I was up to 31.6. This morning I see that at some point during the night I shot all the way up to 36 like many of you also did. I haven't measured the rain gauge yet but my automated gauge is reading 0.10". That would be mostly rain before the changeover. I'm going to record 0.3" of new snow based on the board and trees. Fortunately I still have a solid base of between 2.5 to 3.0" which should be enough to enhance any radiational cooling we see here over the next few night. I'm hoping to see zero Saturday morning. >>Forgot to mention that clearing skies are progressing southward from the north. The sun is about to come out within the next 10 minutes. My temp is back down to 31.6. Yesterday the models showed temps continuing to drop down through the 20's with mid 20's by sundown. Let's see.

How strange with the temp reversing from earlier. It's been very slowly rising and now is back above freezing at 33.1 degrees. I'm still not worried about much loss at the beginning. It won't take long for precip to become snow and start to accumulate. I see the radar is showing rain echoes over me right now but so far it's been dry. I'll be back in the morning (after 9:00) with a total measurement for whatever falls overnight. Off to bed for me now.

Wow. Well I know my memory isn't quite what it used to be. So the time frame was quite a bit longer and it was more recently as well. 364/24=15 days + 4 hours. That's half a month! Impressive. I'm surprised I did not remember those sub-zero record lows. Instead of the snow being mush I think it's my brain beginning to turn...lol. Thanks for the info! I'm surprised I did not hear from @djr5001 with the historical data. He's always been pretty good with that stuff. PS>>My temp has been very slowly heading back higher and I'm now up to 31.6 degrees. Once the precip begins it will bring down the temperature with it so no worries.

I won't keep updating but my temperature continues to drop even though skies are overcast and it is not precipitating. I"m now down to 29.1 and headed down. One other thing that is noteworthy is that from this point forward my temperature is not forecast to rise above freezing for at least the next 7 consecutive days. That doesn't happen too much around these parts anymore. Just going by memory, I think the last such period of consecutive days below freezing was 11 back in January of either 2014 or 2015...which ever year was the brutal cold winter with the "polar vortex". With a high temp today of only 41.7 degrees I lost very little snowpack. I still have about 2.5" solid everywhere. Hopefully after tomorrow morning there will be another inch or two.

I don't know how much I'll ultimately end up with...but surprisingly I'm already down below freezing at 31.3 degrees. Guess I don't have to worry about the initial "mush" NWS was speaking of. lol

Unfortunately, it looks like the nightshift's passing the buck was a wise decision.

@Bubbler86...look at it this way...I was trying to be more like @Blizzard of 93, and less like @paweather.

I'm not trying to be picky. The 18z has the precip arriving a little bit earlier than 12z did...looking like start time between 1 and 2. It actually doesn't stop the precip until 9am. At 4am temps are very close to 32 for most of us and your map up there shows me to be 30 at 7am and i said i was 29 because I was referencing the 12z data. I'm certainly willing to agree that perhaps the first tenth of an inch of qpf is not frozen. Obviously things are changing rather quickly with each run. Regardless, 18z is way better than any prior run on the 12k. 3k is not agreeing very well with 12k, however. But HRRR is closer to 12k than 3k.

Have you gone hour by hour through this event with surface temps? The NAM has the temps between 32-34 right at the start around 4am, but at 5am the temps have dropped to 29, and that's when the major portion of the precip begins. For most of us the forecast high for tomorrow is low 40's for a few hours in the afternoon. With the incredibly cold ground there should be almost no loss of qpf at the start. I think near the projected amounts are doable. BTW, I'm not saying that the much higher amounts at 18z will happen, I just think that nearly all the qpf will be snow and it will stick, even if it's just an inch.

This is...

If you had gotten your wish I would have gotten 2 feet of all snow instead of 13" of snow followed by 5" of sleet. I was in north Jersey back in '93. That might have been the last time until today that a low passed close enough to me to drop to its lowest pressure. Back then the superstorm passed by just 10 miles east of me. It went west of Newark and east of me (15 miles west). I only went up to 27 degrees and stayed in sleet while Newark airport shot up to 38 degrees with rain for a time. The pressure of that storm as it passed by me was 969 millibars, or 28.61".

Well I've waited all afternoon for Blue Mountain to stop eating up all my LES and it finally gave in. Moderate snow here now, blowing around, but intense enough to be accumulating. Another bonus, it sent my temperature down from 32 to 29! >>Snowboard is covered in white now with 0.1" of new, additional snow.
