2017-18 LES Season


josh_4184

Recommended Posts

A few of my favorite pics from last event. This is before the last few days of snow. Has been an awesome last 2 weeks here. Had a 16" event a 20" event and a bunch of smaller 3-6" events. Thundersnow on several occasions during those 2 events. These LES events also have been really low QPF. I have over 3.5" SWE currently. Long range looks good after next week for continued LES chances.

Thundersnow video, turn volume up I missed the best thunder =/

Euro and GFS now in good agreement about the system end of the week to stay south which is good news for the snowpack as well as a welcome addition for some much needed system snow. Then looks like a decent shot at some good LES afterwards and a couple more systems. Forecast for the north woods looks as well as it has in years for cold and snow for Xmas and New Years.

APX had another great write up this morning

Primary Forecast concerns...Wind directions for LES and how cold it
will get Sunday through Monday night. First the winds, During Sunday
night, the ARW is showing LES to redevelop quickly as the cold air
begins to move into the region quickly and the 850-700 mb layer RH
increases. The ARW, GFS and ECMWF agree on the basic wind direction
with west winds that begin to turn to the northwest by Sunday
evening. Winds continue in that fashion through Monday night. This
has the possibility for long duration bands. The other concern, as
stated, is the temperatures. First, this will be probably the
coldest air that we have seen for the season with this stretch
expected to stay below normal into the next two weeks. Couple the
cold temperatures with the winds and we will be around or below with
the wind chills through about Thursday. The second issue with the
temperatures is related to the LES. 850 mb temperatures fall to
around -25c. That is not a great temperature to produce dendrites,
more like powder. However, it`s not as simple to say that with the
cold temperatures we get small flakes. With the radical instability,
there have been times the internal cloud temperatures warm a bit,
and makes for better dendrites. However, low visibility will be the
case regardless in the bands. So moderate to possibly heavy snow
bands will be possible through the period. However, with all of this
cold air we could run into icing on the Great Lakes, especially on
Green Bay cutting the Fetch off for west flow situations. Will have
to see how this turns out, but it is looking good.

Looking epic. I'm heading back home from Detroit area early the 26th. Will have missed most of it, I think.

 

But look. It's breathtaking. NWL and Munising/east and Keweenaw - awesome.

I would hate to live in Escanaba...the banana belt of the UP. I think I'd rather live anywhere else in lower Michigan than have to live such a short distance away from hundreds and hundreds of inches of snow.

On my way down from Calumet...the Keweenaw and your area just south of Gaylord had the most snow of the entire trip. Munising was third place...but not really even close to the Keweenaw and the NWL south of Gaylord.

Thats the norm, but actually SW of Gaylord around my location is usually higher yet, we generally get 10-15% more snow then Gaylord city area. Picked up about  5" of major "fluff" tonight so far. Tomorrow thru X-Mas looking very interesting.

Holy moly at the 00z GFS.  One of the best lake effect signals I have ever seen from that model off of southern Lake Michigan.

Definitely brings the next Sunday storm further north and the lake effect afterwards is more oriented towards Indiana rather than Chicago and Milwaukee

Edit (10:33pm): Okay it does shift a little into Chicagoland

Superb fetch (with upstream connection) with excellent thermodynamics and the band has minimal movement for a good 18-24 hours on that run.  That is national guard/emergency type stuff on there haha.

That's insane, I would drive down to see that but I don't think I want to be stranded lol
