Winter of 2011-12, eh?

am i thinking what your thinking? MKE late night special. Not that I know what I'm looking at, but sure looks like they will get WAA wing and then perhaps the deformation band. Again,just watching radar trends ...and its early.

i think we'll still see a decent period but intensity is trending down with each RUC/HRRR run... 2-5 still looks good, probably no TSSN.

If nam Verifies 1-3" for all S/E Mi.. What I don't get is how the hell does that LP basically move east at hour 12 and then hour 18 NW to Detroit?

I guess it gets sucked up to the north when the H5 low closes off. The whole trough axis and vort max is still moving east though. Seems a bit extreme to me without the trough going extreme neg. tilt, but there's definitely some consistency starting to show up so it's not without merit.

The central axis of the band is now moving into Wisconsin. Virga here and 36/29. Precip should begin in the next few hours.

Very impressive to see snow accumulations despite above freezing temps to the south, shows how hard it's snowing. Freezing temps spreading through a pocket of NE IA and NW IL.

You just might be able to sneak into the 3-5" zone.

Called it! :scooter:

0z Nam showed 4-6" north of 401 and 2-4" south of 401. Its alot better than the 18z Nam.

Some nice new bands taking off over and just northwest of DVN. Also some cellular precip down near Galesburg looks interesting. Precip should continue to rapidly increase and expand over northern Illinois over the next several hours as that vort in Iowa moves closer.

Btw, rain/sleet mixture here.

what are your thoughts on radar trends for our area?

everything seems to be going close to what was expected for now.

convective-ish elements are present down around GBG/MQB, with a rapidly developing/intensifying area of snow along and north of I-80 in E. Iowa/NW. Illinois (including some nice meso scale banding). this will all move intot he LOT CWA over the next few hours.

earlier call of 2-7" along/north of I-80 looks good (localized high amts). still think the heaviest axis will be from Lee to Cook Co...but the given that the earlier FGEN band overproduced up north, the axis might have to be expanded up there too.
