First batch of snow is pretty much done, with only 0.1". O well there's more winter yet to come.

Not saying it will amount to much but there is persistent light returns showing up on KDVN. Still good warm advection ongoing across the cwa and a 60 kt 500 mb jet streak over eastern IA according to the mesoanalysis page. The aviation forecaster on duty tonight indicated -sn potential from 9-12z in the tafs.

Have to keep an eye on that streamer over L Ontario in advance of the clipper.

Definitely think some lake enhancement is possible once the band moves through (after about 18z). Sfc flow is out of the SE with nice saturation through 700mb. Inversion height sets up just above the 850mb mark which is a decent look for these types of events.

Seeing some 30+ dbz returns. Given the high ratios, probably 2-3"/hr rates in the heart of the band.

 

Sucks that SE flow fringes Etobicoke. :(

Merry Christmas man :)

What a nice treat seeing snow on Christmas, haha. My thinking is a general 2-5cm across the GTA from the clipper with locally higher amounts of up to 10cm in the LES areas.

Where do you suppose the LES band will set-up?

Managed 0.5" as of 9 am. 

 

Second batch is on its way I see.
