Actually this is not surprising. When there are very windy conditions following an arctic blast, the surface temp is dictated by what's going on aloft. The 500mb thickness level bottomed out close to 504dm around 10:00pm. For the rest of the night it will begin to rise. Temps at the 850 level also play a role. The temperature at that level also reached its bottom at -18 degrees C around the same time. It also begins a slow rise higher throughout the night reaching -12 at 12z. Therefore as long as the wind remains substantial it is not likely that our overnight temp drops more than a degree or two lower by morning. Only if the winds diminished to less than 5mph would the snowpack then contribute to radiational cooling. As I type this it is now midnight and my temp is sitting at 20.3 degrees and has only fluctuated a few tenths over the past 4 hours. It actually bottomed at 19.9 at 10:38pm and has risen slightly. It's quite possible our temps don't drop at all from whatever level they're presently sitting at. In this case elevation dictates how cold it is...more or less...referring to constant winds > 10mph.

@ItstrainingtimeI'm surprised you didn't think of all days in weather history...the Superstorm! Tomorrow is the 29th anniversary. You were mentioning low temps for today, late this afternoon in the low 20's. Well, back on 3/13/93 I was 17 degrees with heavy sleet in the middle of the afternoon. Today's weather had tidbits of weather elements that came with the superstorm...but definitely not the barometric pressure, which was 30 millibars lower than today's minimum pressure of 1001.

I can't get over how @Blizzard of 93 has had double the snowfall and conditions that I've almost never had during this storm. About a half hour ago I had several wind gusts into the 30's with wildly blowing snow...but that only lasted a few minutes. It's been snowing mainly lightly since 1:00 but not enough to accumulate further. The winds which had been pretty breezy have backed off a bit, although I'm getting a good gust as I write this. Back at 1:00 I recorded no additional accumulation with a storm total of 2.3". Temp continues to drop, now down to 23.5 which is the low of the day. The max, at midnight was 46.7.

At 12:00 noon it continues to snow lightly and there is some blowing snow taking place now. Since my report 30 minutes ago only an additional 0.1" of new snow has fallen. Since 11:00am an additional 0.3" has fallen bringing the storm total to 2.3". The temp is beginning to fall again and after rising to 28 it has fallen back to 27.0. The pressure has leveled off at 1001 millibars and has been steady for the past several hours. Wind continue to ramp up, sustained between 10-15mph, gusting occasionally to 25mph. Judging by the radar it looks like the snow portion of this storm is about to rapidly wind down for me, meaning that my storm total will likely be just under 2.5". >>Yes, my NWS feed is also screwed up. It says that I am still in a winter storm watch (the one from yesterday) as well as a winter storm warning. Interesting.

Here's an intermediate update as of 11:30am, the heavy snow has ended and it's back to light to occasionally moderate. The heavy burst, which lasted less than 20 minutes, deposited only another 0.2" giving a storm total of 2.2". I think there's partial melting or compacting going on even though the temp, which dropped to 27.3, has risen back up to 27.9. The winds are definitely beginning to pick up, now easily gusting over 20mph and sustained around 10mph. Not much in the way of blowing snow so far. According to Blizz, just 20 miles east of me, it is a whole different world with the heavy snow and blowing snow.

Sadly, today is the last day of nature's true time...standard time. Tomorrow morning at 2:00am we jump forward to 3:00am as daylight saving time begins and lasts for the next 8 months! It used to be 50/50 with the time split...but then Congress had to stick their nose into it and pull back the start time. The first time, in the late 80's they pared it back three weeks to the first Sunday in April. Then they decided that wasn't enough and at some point in the late 90's they pulled it back 3 more weeks to the second Sunday in March. Oh, I forgot, around 15 years ago they delayed the return to standard time by pushing it from the last Sunday in October to the first Sunday in November.

Finally! Best flakes and heaviest the snow has been the whole storm. I'm in that heavy band now. Started about 10 minutes ago. As 11:00am the temperature was down to 27.5 degrees and heavy snow was falling. During the past hour 0.3" of new snow accumulated...all of that in the past 15 minutes. Storm total now is 2.0". Well, at least my grass is completely covered now...lol. Amazingly my street has been melting and has very little snow left on it.

Wow!! By some of the "ripping" and "whiteout" reports I thought you were really getting the goods. So far does that mean that @Bubbler86has the most with close to 5"?

At 10:00am in Carlisle it is snowing lightly with an occasional moderate burst. Temp has dropped further to 28.2 degrees. Winds are a bit stronger but still below 15mph sustained. I hate to say it but it's looking more and more likely that this storm isn't meant to be for me. As of now WHTM's C-2" is on the money. During the past hour I picked up an additional 0.2" for a storm total of 1.7". Looking at radar, if I'm lucky that big band that looked like the heaviest of the storm will be approaching my area within the next hour or so. Maybe that will be enough to push me over the 2" mark? Definite congrats to York/Lanco folks who definitely deserved a good one this time around!

At 9:00am in Carlisle the temperature is down to 29.5 degrees. During the past hour only an additional 0.3" of snow has fallen (sadly). This brings the storm total to 1.5". Winds have been variable between <5mph to up to 15mph. The snow intensity was never more than moderate and with fine flakes not much accumulated. Let's see what the next hour brings.

At 8:00am in Carlisle the temperature has dropped to 31.3 degrees. It dropped below freezing about 30 minutes ago. It is snowing moderately with finer flakes. The winds were practically calm 30 minutes ago but now have begun to pick up...5-10 mph. New snow and storm total is 1.2". Looking great out there. Aren't Saturday snowstorms great? Remember Jan '16?

Yes. It did accumulate on the highways. NWS warned of that in their warning. It took the two ingredients you always need....temps below freezing, the lower the better, and sustained heavy rates of inch per hour or greater. That's why I'm expecting no problems with road accumulations here tomorrow. The temp will be getting progressively colder, and we'll have several hours of fantastic rates. I don't expect the roads to have as much as the grass, but it won't be far behind.

Last year, I think in September, out in the Denver area they were experiencing record high temps near 100 degrees. Later that same day they were under a Winter Storm watch with temperatures in the 90s...(later a warning) for temperatures plunging into the 20's with six inches of snow by noon the following day. That is easily the most extreme example of the weather flipping from summer to winter in a matter of hours I've ever heard of. My brother-in-law lives in Golden, the foothills west of Denver and reported to me about those conditions. That makes today going into tomorrow look practically like a mediocre event...lol.

They must be having data problems. I'm glad to hear the warning is issued. But as @Itstrainingtimejust said it would be nice to see the details. I'm sure it will finally update before midnight. Thanks for the input/corroboration.

Hey Guys...my NWS (weather.gov page) still has me in a Winter Storm Watch issued from 4:26am. I haven't seen anyone mention being in a warning here, but they have to issue the warning at least 12 hours before the start of the event. So, ???

@Itstrainingtime Sorry I didn't get to post my storm totals from yesterday. It actually was pretty interesting in that I had a ton of liquid, none of which was rain, but not that much snow either. Total liquid (melted) was 0.47". Total snow was 0.8". It really was more than that but it kept melting as it was hitting the board. Temp was close to 33 degrees for nearly the whole event except the final hour or so when it rose to 34 and eventually to 35. For being such a wet snow you'd think it would have stuck to everything, but most of the trees had very little stuck on them except the evergreens. The snow to liquid ratio came out to a ridiculous 0.6:1 which I don't think I've ever measured from an all-snow event before!

Quick noon update. Accumulating snow pretty much winding down. Temp up to 34.0. Officially 0.8" on the board.

Best flake size and rates of the entire event right now. I'd say 1/2" / hour rate. Easily have around 0.4" on the board now. Temp still locked at 32.9.

I've had nothing but snow from the start. It's been going back and forth between very light to almost moderate with nice flakes. Grass has a blotchy couple of tenths of white. Some mulch was also picking it up but some wasn't until about 5 minutes ago. Now it is starting to stick everywhere in my backyard including my pavers. The temp has been pretty much locked in at 32.9 degrees. I've got a couple tenths of slushy snow on my board. Well after a short burst it has gone back to very light...lol. Oh, the temp has just dropped to 32.7...(yay).

Nice to have 2 events back to back here in early March. I was concerned about temps late this afternoon when it was still in the low 40's, but then despite the clouds the temp kept on dropping all the way back to almost 32.0. It was just up to 31.1 about 10 minutes ago but suddenly has dropped back to 32.7 now but the dew point is 28 and the wet bulb is 31.1. If the snow starts early enough that will send my temp down to at least 31, or maybe even 30. If rates keep up even moderately so that will prevent the temp from rising above 32 until late morning when the majority of the event will be over. Better yet, the Saturday event really could become something sweet with a nice blast of cold coming in behind it until probably Monday afternoon.

Holding at 62.6 here with CALM winds. The cold air does not appear to be anywhere close to behind the front. The rain is already half way through Pittsburgh but they're still in the upper 50s all the way back to central Ohio. Should be interesting this evening. BTW, my low this morning was 52.2. That would blow away the max min for today if it didn't drop below that by midnight. If the colder air does lag behind the front perhaps temps could still be around 50 even at midnight?

A balmy 64 degrees at 1:00 AM! as I head off to bed. These conditions literally could be a normal night in late June. It does feel nice out there...but it can wait another month while we deal with our upcoming snow chances.

Low this morning was 37.0. Clouds were slow to break all morning with the temp only slowly rising up to the low 50s. Then all of the sudden someone flipped the wind switch on and I had sustained teens gusting to 30. Temp peaked at 75.2 a few hours ago when the sun was out the most. Then the clouds returned to overcast and the temp began to slowly sink, now back down to 71.2. Today also was a 38-degree diurnal. Wild March swings for sure.

32.2 here for my low this morning. Up to 45.7 now.

At noon nearly 100% of ice has melted off. In shaded areas there are still patches of "white" remaining...but not for much longer. My temp has skyrocketed up to 41 degrees and the sun has occasionally been out. The clouds had broken up a little while ago but now a more solid overcast has returned. The windy conditions in the forecast today have yet to materialize.
