Edit: re. [mention=18064]mannynyc[/mention] post of sim ref a few posts above

Looks good for a squall there tomorrow. Too warm in NYC and LI to accumulate but surface wet bulbs and wet bulb zero heights are low enough for it to probably be snow if it stays coherent as it comes through, which both the HRRR and NAMnest are hinting at.

If this happens, could be some brief fun, with heavy snow and 40-50 mph gusts. These soundings are pretty classic, featuring very deep mixing, very steep low to mid level lapse rates, sufficient moisture, and instability. Could get a quick coating over interior sections. 09e5ca53cd41b670bfe9f97dc1a794b3.jpgb61a022d78557cd35f3c1fab8ec1ae26.jpg

Are you where they had all that flooding?  So sorry man, I saw pictures and videos out of the area and people were driving around in boats.

I live a few towns over and it flooded down the block and is flooding right now with tte high tides on the hackensack river.

If you are north and west of the city tomorrow you will definitely need to look out for some nasty snow squalls.  This will be particularly true in the Poconos over to the Catskills.

I think the Governor was behind this and given the expected conditions it is probably the correct decision.  It’s always interesting to watch these games played in these conditions however when you have tens of thousands of people going out on the roads to get there this is probably the better call.

Keep in mind, a map or any representation of differences in normals (1981-2010) to (1991-2020) is actually a measure of one-third of the difference between (1981-1990) and (2011-2020) because 1991-2010 are two thirds of both data sets. So if a map shows some location warmed by +1.0, it means 2011-2020 was 3.0 warmer than 1981-1990. 

Under the cold dome here, about -10 F which is probably within a few deg of record low max, about -20 F for overnight lows here. Sky is the same intense blue color that we had during the heat dome in June 2021. Trees are plastered with snow from days ago, and s.o.g. is about 20" in town, 30-40 inches in the nearby ski areas, and 15" down in the Columbia valley. These are near to slighty below average snow depths for our region. Only in January 1950 was there anything colder than what we're seeing across BC now, since 1950, a few other occasions were near equal to today. 

As I posted yesterday, Watson Lake Yukon had -74F on Jan 31, 1947 so their lowest value so far (-57F measured as -49.4 C) is not record-setting but there are only a few other cases of even -60 F, the 1947 spell was an outlier. Alberta and montana are probably closer to their all-time record lows, quite a heat island showing up for Edmonton, the station you're seeing (YEG) is 15-20 miles out of town, in the city it is running about 10F warmer. The Calgary airport readings are somewhat within suburban portions of their eat island, their airport (YYC) is a lot closer to downtown than YEG. Almost any other weather station in Alberta will have no urban effects, but you do get topographical variations in these calm cold spells, as solar radiation in January is negligible, so the overnight cold stays noticeable in valley bottoms all day.
