About 2" here on grassy and elevated surfaces. Paved surfaces mostly just wet/slushy.

Wind is ripping downtown. Surprised there are no warnings.

I always figured that was just elevational effects mainly. PIT is at 1201', while SYR is 420' and BTV at 330'. There's usually not nearly as much of a north-south gradient in the summertime - in fact, many times with a big summertime ridge, there's warmer air aloft spreading in from Canada than there is further south. The moist adiabatic lapse rate is 3.5F per 1000 feet and dry adiabatic lapse rate is 5.4F per 1000 feet, but superadiabatic lapse rates can occur. Plus because of SYR and BTV's location, they get downsloping from most wind directions. PIT would only have downsloping from the east, otherwise generally a mild upslope flow (1200' being one of the higher points, which makes sense because it's an airport - there are a few 1300-1400' spots). If you look at last year, PIT had 5 90+ days, while SYR had 18 and BTV 14. However, BGM at 1627' only had 2 such days. I imagine if records were still kept downtown at say 800 or 850 feet, there would be more. The hot Syracuse temperatures are always a point of contention with the locals here, but elevation effects alone suggest it should be 4-6 degrees cooler in an atmosphere with adiabatic lapse rates than nearby Binghamton. I would imagine subtle downsloping effects and a more urbanized environment could even enhance those numbers somewhat. Obviously, in the winter, these trends don't hold. Temperature inversions are common, and lapse rates lower even in the absence of a temperature inversion.

Surprised that they didn’t get any accumulations over the last couple days. We had at least a half inch, if not 3/4 of an inch in my backyard. Kind of surprised with the trace yesterday too, as there was certainly a light dusting near the airport which normally means .1 or .2 on the snow board.

Meh, we're not really missing anything. Even north of I-80, it doesn't look like more than an inch or so. You have to be way up near the lakeshore in Erie for this event to maybe pick up a few inches (but anything over 3" there would probably have to come via lake enhancement/lake effect as the storm pulls away tomorrow). Most of those advisories are for a tenth or two tenths of icing, with only light snow/sleet accumulations. I'd actually prefer 33-36 and rain, over 30-33 with icing concerns. Western New York might do all right, but even there it looks like mainly 3-6 inches which is really nothing for that region.

Meanwhile OKC has thunder, snow and sleet with a temperature of 11 and windchill of -7. https://w1.weather.gov/data/obhistory/KOKC.html

Yes, doesn't look like this should be nearly as big of a deal as the early February event that caused a lot of power disruptions west of Pittsburgh. That one was kind of a unique event with the cold air pressing south. This event looks like it should be a more typical storm track with warm air surging northward. Still most of the models at this point in time would support at least a glaze of ice to perhaps a tenth of an inch or so north of the city. I know some of the ice accumulation maps show a lot more than that north and west of the City, but that's right around 32 so I wouldn't expect much accrual. Won't be 30/31 like in the early February event. Also should rise above freezing areawide at some point with just plain rain for several hours.

Well, it looks like the GFS has surrendered on the snowfall front. Still shows a modest snowfall north and west of the city, but the heaviest accumulations are well off to the north now. Regardless, looks like another precipitation bomb. So probably a good idea to keep an eye on this as their could be more significant ice accumulations for parts of the region. Looking at the temperatures shown on the GFS (probably underdone) but they keep it generally below freezing for the city (29-31) until the low approaches when it spikes into the low/mid 30s for a few hours, before dropping back into the 20s.

The GDPS looks a bit more realistic to me with its depiction

Turned sunny here, now a second squall popped up.

Yeah, that was showing up as 40 dbz on radar.

Surprised there’s no snow squall warning for this. How bad would it have to be to get one?

Quite squally here now.

Snow squall band looks to be training and setting up more parallel to the flow, rather than perpendicular to the flow. Maybe we can pick up an inch or so.

Looks like there may be something to track late next week. The GFS, Euro and Canadian all have a low passing to the south. May be a similar setup to the event earlier this month.

Yes, it's not really going on on that much of a limb there. Certainly wouldn't be the first time we went two weeks in early February with less than 3 inches, but probably 7 of 10 years that number would be met (given the average is 6.7"). But 90-100% would definitely be better odds than just strictly climo.

I think what we need is a storm to track like the November 1950 storm, or the White Hurricane of November 1913. Not sure if you guys are familar with that one - has the daily record of 12.5" on the 9th of November. I think storm total downtown was like 14" with 12-24" widespread throughout the region. I always thought that was just some storm up in northern Michigan, but I guess it was a potent northern wave that produced strong gales. Then a new low pressure formed in the southeast coast on the cold front and retrograded northeast to Erie while bombing out with a negatively tilted trough. I think either of those tracks would be really good for us. Superstorm Sandy came close but was too early in the year for snow outside of the mountains.

Some of the models were suggesting YNG airport could get 16", and I checked and there has not been a two day storm total that higher there since November 1950. And compared to Columbus and Indy at a similar latitude, PIT has had way more big storms.

I think some people like to complain about Pittsburgh, but given its location and latitude, 4 official 20+" storms is actually pretty good. Toledo has only had one, and that was in 1900. Detroit has only had one, and it was in the 1800s (in April, no less). And there's been several others that have produced 20"+ in the area, but were somewhat less at the official observation site.

Just for context… Toledo’s 12.5” storm total was sixth biggest on record. https://twitter.com/jayberschback/status/1489460096140775428?s=21

Power just came back on after nearly 16 hours…

Still no power here.

Same here. I can hear branches and tree limbs cracking and falling in the woods.
