    Lots happening

    The clipper has really ramped up the NW winds in Manitoba, with up to 35kt winds at 900mb tonight in Manitoba and Saskatchewan. The cold air avoided us for so long, it's hard to believe the arctic blast is going to slide right in here. (Already measured 34kt, gale force, wind gusts at Brandon Manitoba)

    I made this map of a storm that happened 50 years ago, with marginal temps, and a cut off low, perfect for pulling some Atlantic moisture back to Detroit

    that's excellent. I think that's from ice clouds in the lower atmosphere, right? (no water droplets)

    flying a direct route from the North Pole to Chicago, it's Santa Claus, wait, no, just air.

    snowfall analysis, apparently updated at 00z, (and 12z) which I totally forgot about
  7. Chinook
    new precip since the LES started. I've seen local storm reports of 17"-22" at Erie PA, and nearby. (not sure if there's any more updates)

    Got a bit of luck today on checking the web cams: lenticular north of Denver

    you don't always see a reasonable value of CAPE when the LES is going

    NWS official snowfall forecast (48hr)

    Looks like the high 500mb heights and warm 850mb temperatures in Russia and the Bering Sea are bumping the upper level features to be cold in North America.

    moderate snow at Denver International Airport right now

    here are some rouge waves for Roguewaves

    New winter storm warning above 9000 ft, also, winter storm watch and also an advisory for the Palmer Divide NAM/GFS have 40" for Crested Butte with over 3" of QPF
  15. Chinook
    some crazy ensembles with some ensembles with heavy snow at Chicago, Indianapolis, almost St. Louis

    the football game is nothing but white!
  17. Chinook
    heavy snow bands near the football game tonight

    This is a rapidly changing jet stream disturbance that's going to get the new low pressure going in Ontario, going backwards, as the rest of the trough goes forwards.

    I believe the 1864 storm is covered in "Thunder in the Heartland," by Thomas Schmidlin, weather historian. When I read that book, I didn't make any specific notes, as it was almost impossible to find a weather observation that I could have included on my web site. If you look at the Daily Weather Map archive from the government (back then it was the US Weather Bureau) you can only see back to 1871 (amazingly).

    Sea-Tac had 55mph wind gusts from the ESE, and I have heard 500000 are without power around Seattle with similar circumstances with some easterly downslope winds. I've never seen a low pressure get down to 945mb so quickly unless it was a hurricane, I think.
  21. Chinook
    blizzard warnings, hurricane force wind warning offshore, high wind warnings
  22. Chinook
    this low was 1000mb at 06z

    Typhoon Man-Yi: JTWC said 130 kts before landfall and 90 kts after landfall, with news reports saying 121mph(105 kts) at landfall. Here is the image at landfall.

    Some GEFS ensemble members and the ECMWF have a low pressure near Toledo or Detroit with snow to the south. I expect that models will take a few days to come to agreement on this dynamic system
  25. Chinook
    maybe it warmed up a bit at Boulder for these guys
