NWOH finally getting in on some snow action today... probably won't do much but at least it's better than the 34F and rain

 

instead of 34 and rain you have 36 and snow... :lol:

 

Today epitomizes everything I hate about late Feb and March when it comes to winter weather.   Raw, drizzly, and mid 30's....will soon transition over to raw, non-sticking wet snow and mid 30's.   depressing as hell.

There are a lot of very sad and droopy trees in Ann Arbor today. 4-5ish inches of pure cement on top of freezing rain/sleet base. 10-15' pine tree near me actually was pulled over and pulled out by its roots.

Like a broken record, ARB area wins again. Though I do have to say 7.4" surprised me. Does that sound a bit high? Of course with thr slushy cement I ts hard to measure.

Great pictures Harrisale!

Beast - Looks like that LES band or lake enhanced band will slide through most shoreline area from Waukegan up to your area. Just small flakes here now. 1-3" in my grid for this afternoon.

My 4-5 inches was based upon an area that might have gotten tree melt falling on it. On further examination, it was probably 6 or so IMBY. 6 inches of total cement. The peak area seems to be smack dab in central Ann Arbor which probably had an inch or so more than what I got. Lots of tree damage in the area.

Thanks! you seem to have taken the cake

It appears the 4km NAM was nearly spot on with totals in your backyard. If only it were as accurate for here we would've been over a foot as well. Some warm air intrusion it must have missed in modelling southern Ontario.

Fun storm though :)

Definitely a fun storm and tonight I will be really sore! lol

 

Just saw this from about 70 miles north of here where they had drifting snow! - to 6'.

15.2" - through 11:50am. Sticking on untreated surfaces only now.

All sorts of convergence zones across southern Wisconsin today. We're in the middle of a mini baroclinic cyclone it looks like, with a warm front like convergence zone extending across Lake Michigan, a very diffuse cold front structure extending down into Iowa, and another associated band near the backedge hitting La Crosse. That puts Madison near the triple point, we have bands approaching from the north and east. http://tempest.aos.wisc.edu/radar/wi3compflash.html

Still snowing here, but only sticking where the sun wouldn't be shining and on the existing snow. About 0.4°C now.

 

Actually system snow as LOT put it, through 7am was about 14" and these leftover snow showers have tacked on another 1.2".

 

Can see some heavier band to the ENE drifting this way.

500 mb analysis confirms that it's a baroclinic cyclone, it's a mid-upper level feature with little low level signature. East winds and warm air advection across northern IL and southern WI with cold air advection in western WI down through IA. The band over La Crosse is more of a warm front than the feature over Lake Michigan, which is a convergence zone but doesn't have typical warm front structure. That band over central IL is probably the cold front, stuff over Iowa is more of a TROWAL (trough of warm air aloft).

So where is that structure going to pinwheel off to? Southeast I'm guessing.
