For those of you that received snow last night....is it sticking around or has it completely melted already?

It's mostly all melted. The only areas of my yard that still have some snow left are areas that are in the shade. The October sun and temps in the upper 30's make it hard for October snowfall to last very long on the ground here.

Received 3.1" here overnight. Anything hit by the sun has melted but anything in full shade is sticky around - for the moment. Expected to get close to 40F tomorrow so I suspect most of it will be gone by tomorrow.

DVN sounds pretty optimistic for tomorrow night.

 

 

Wednesday night and Halloween: A more potent storm system is still
expected to impact the dvn cwa. GFS/ECMWF bringing a potent
negatively-tilted trough and deepening cyclone coming across the
Midwest and into the eastern Great Lakes. Models indicate a
classic closed h5 low and deformation zone that will track across
the dvn cwa. Snow should begin spreading into our western
counties by late afternoon, then continuing to spread across the
remainder of the cwa during the evening. Moderate to possibly
heavy snow is then expected later in the night into Thursday
morning with mainly light snow for much of Halloween. The snow
should finally end west of the MS River by late afternoon and in
the eastern counties during the evening.

There is the potential for 4 to 6 inches of accumulation but this
is still subject to change so stay tuned to later forecasts and
updates. Headlines for this event may be needed as we get closer
to the event. This will be a very cold Halloween with highs only
in the lower to mid 30s. This would make for possibly the coldest
Halloween ever recorded! See climate section below.

One of my neighbors' front yard, which is in the shadow of their neighbors' giant oak tree, is totally snow-covered.  Every other yard on the street is green.

@ Tom

 

From Met at Amwx

 

Pulling a bunch of stats right now for select cities in the area...and as modeled, this is going to be a historic/record breaking event.

 

Congrats on a great call if all goes as planned!  ;)

For Wed

 

.AVIATION...(For the 18Z TAFS through 18Z Wednesday afternoon)
Issued at 305 PM EDT Tue Oct 29 2019

Currently we have MVFR cigs over the western TAF sites and IFR
cigs over the eastern TAF sites at 1730z. Drier air will continue
to come in from the northwest so I expect all areas so see skies
become VFR by 00z or so. There may even be a few hours of SCT
clouds after sunset.

This period of VFR will be short lived as developing system will
send moisture northward and bring lowering clouds and precipitation
by 09z to 12z in the southern TAF sites and 12z to 16z in the
northern TAF sites.

The air will be cold enough this time for mixed rain and snow or
possibly even just snow. The areas most likely to see snow are
GRR, AZO, and BTL. Do expect moderate to heavy mixed icing
tomorrow in the clouds,freezing levels will be as low as 1000 ft
during the morning. This area will have signifcant SLD
(supercooled large drops) threat with this. This may well present
a significant flight hazard.

 

For Thu

 

A more impactful wintery mix of wx will come Thursday into
Thursday night as the low pressure system passing by to our se to
east continues to strengthen. This will result in brisk north flow
caa that will cause a gradual changeover from rain to snow across
our fcst area (generally the changeover will occur from nnw to sse
as suggested by low level critical thickness tools).

Initially we suspect that quite a bit of melting will continue to
occur due to relatively mild ground and pavement temps. However as
temps slowly fall through the day and especially Thursday night
after nightfall we expect hazardous travel conditions to develop
as snow and slush begin to accumulate on area roads.

Living on the lake is literally the worst sometimes! I’d love to see snow but I think we’re too warm it looks like :(

 

With the wrap-around deformation band shifting winds more NWesterly, you should at the least see nice mood flakes, if not accum's on streets. You will score big time once we get into #actualwinter

Ugh.  The other 18z models trended favorably for southeastern Iowa, but the 18z euro is the worst it's ever been for this area.

Euro zoom-in (for Tom and Chi-town peeps). Gives me more snow too, but maintains the nasty gradient I'm all too familiar with, lol

Haha, however it is way too early in the season for that yet Clint even though I do feel your pain... I think that you are due for some big hits this year after getting the shaft last Winter. 

 

Any snow that falls around here in October is a pure bonus for snow lovers. Plus, I would much rather see a big storm hit us in the middle of the Winter as snow this time of year is mostly gone in 24 hours or less after it falls, I was shocked at how quickly our half inch of snow disappeared this morning once the sun came out.

 

The "real" show around here is still a month or two away yet.
