Possible frontal wave snow


Zelocita Weather

The 18z RDPS (regional Canadian) shows between 0.3 and 0.6 frozen across most of the area.  This is a similar depiction but maybe a notch wetter than the NAM and GFS.  The GDPS is slightly drier and further east with the boundary.  The 18z ICON is SE and dry (not enthused) and the 12z UK was pretty wet (QPF).

I think the best chance for accumulating snow will be near or just after daybreak as surface temperatures finally approach freezing.  This looks like a general coating to 3" or so, depending on location.  But I also think someone has a shot at 4"+.  It could be a surprisingly snowy Wednesday morning.  Not a blockbuster but 2-3" in a few hours can create a very wintry appeal.

Yea probably someone just NW of the I95 corridor will have the best shot at 4+ where theres enough cold air and enough precip

The 0z RDPS is wet and cold - even better than 18z.  It suggests 2-6" regionwide with some sleet to start.  Gotta hedge lower at this point but confidence in a snow event is increasing.

It has about 14mm. Looks really good.

Keep expectations in check but these can bust in a good way as we saw in the past.
