    Models generally have Larimer/Weld counties with pretty low amounts of snow. I believe it is due to mainly downsloping from the north at the surface. Also I think a lot of the lift will be towards southern Colorado.

    The models predict a significant snow storm next Wednesday. As usual the GFS is loving the 11.8 to 18.1" near Denver, as it always loves forecasting high amounts of snow for the roughly 5-day forecast. Lots could change before the NWS issues a winter storm watch, but I do expect a winter storm watch at some time.

    This 500mb chart makes me think of tornadoes in March. As for now, SPC has 10% enhanced outlook for tornadoes today (-not- enhanced for wind/hail)

    It's so snowy, you can't even see the prediction

    54 degrees warmer for Ontario

    My place had 4 sunny days in a row with snow on the ground. The last time my place had 4 sunny days within maybe a span of 5 days was probably November or October, with nearly summertime temperatures.

    As I mentioned in the Lakes/Ohio Valley banter thread, I have a hard time imagining a -44 degree value without radiational cooling and a valley with lighter winds, or at least some localized low spot. It's truly a once-in-a-generation 850mb temperature up there and also the same for wind chills for some.

    finally caught a good cloud

    I can't imagine -44 without radiational cooling and mostly calm winds.

    The wind gets faster over mountain peaks and some mountain passes. The air is forced into a smaller- volume space: the mountain, and other air above it. You get a faster wind by conservation of mass flow. And maybe extra turbulence.

    Here a note on the Northeast wind chill blast. The GFS has -40C temps at 850mb for the Caribou, Maine area. I think it will be very close to a record or record-breaking at Caribou. The record coldest 850mb temperature is -39.40 Celsius as per the SPC page that has this stuff. The "median" would be -11.7 Celsius.

    Here is other note on the Northeast wind chill blast. The GFS has -40C temps at 850mb for the Caribou, Maine area. I think it will be very close to a record or record-breaking at Caribou.

    Part of Ontario near Sudbury is 49F degrees, or 27.2 C degrees, lower than yesterday. Sudbury went -4C to -33C in about 23 hours.

    48 hrs of storm reports. I have changed the colors a bit so you can read the freezing rain reports.

    This is a rare wind chill index (Maine), also with winds of 30kt immediately above the surface.

    This would scare me

    Now that a lot of the West is in a non-active pattern, I'll post this

    Anybody from Toronto in here? The GFS says -14F (-26C) with a wind of 10 knots (19 km/h) on Friday morning. The NAM has some temperatures that are not quite so cold.

    Fort Worth had 0.30" reported freezing rain. Other note: thunder recently reported at the Dallas area and also Poteau, OK (temps below freezing on both)

    1.4" of sleet at Bentonville is an impressive storm report tonight when you've got 4 precip-type colors on radar

    my place got about 1/2" (surprise!)
