Observation time - we talk about this every winter. Sun angle. 

People have strong opinions on this. Here's mine...it really comes down to rates. If it's legit +SN and 33 degrees in early March, it WILL accumulate on ALL surfaces. It might struggle midday, but heavy snow (like verifiable 1/4 mile vis or less) will overcome sun angle and to a large degree...temps.

I cleared off my sidewalk at 11am. It is snowing "nicely" right now...verified steady light snow. It's currently 28 degrees and it's January 19th. All of my paved surfaces are 100% wet. Snow is melting on contact despite being several degrees below freezing and still in January.

It really is about rates. 

Now, if it was December 22nd and 22 degrees...this same rate of snow would likely be sticking to all surfaces. 

Agree with everything but would add that it's a thin overcast and I've been seeing the sun off and on through the morning ever since the heavy stuff moved out.  Add to that the fact we're at a solar max, which I  know I've mentioned a couple times recently already, and that boosts the melting process.

Great post.  Hey Training, on what kind of surface do you take your official snow measurements? 

Flat piece of wood about 10' from my patio and adjacent to my weather station. When home I follow the "book" on measuring as best as I can.

930 Am on top...Now below.  May be some mountain interference with radar but the snow to our west is definitely lessened.   HRRR now suggest we are left with heavy snow showers/streamers this evening where someone could really jump an 1" fast.

I’d think our area would have a decent shot at a streamer given all the hills/ridges off south mountain and the catoctins

Definitely agree though still a matter of luck.    I get a nice one and it would push me to WSW.     I got all the current snow off my driveway before the arctic plunge got her.

Yes sir, and I guess I should have added to my original post the assumption that if we were getting legit heavy snow, the overcast would be much denser/lower and limit the radiational affects of the sun.

M4.1”.   Snow depth is 7”.   Marking this storm down as a win!!

im going to guess this is just on surfaces that were all rdy snow covered for the 4.1? cause going to my dads I think the most he had in Middletown was 2.5 that was on the back porch table thats metal. Hardly any thing laid on the sidewalks roads here

Just came in and have a solid 4 inches. In a lull now.

This is the 2rd time today I've made a post about 2 seconds after someone posted essentially the same thing. Happened earlier with @Superstorm comment about the visibility dropping. 

How much do you currently have OTG? See my post above for my current snowpack.

as well you should.  Really light snow here and holes in radar say were close to a wrap here.  Last measure for me was a pinch under 4" and it absolutely was a win for most of us as per obs that are being shared.

Just got done doing my neighborhood snowblowin n cracked my last mad elf in celebration of a snowy weekend.

You bring some good stuff to the group.  Glad you are with us.

We are way west of you....an hour or two.  Me more so than Cash. 

Any freezing should be well after dark.  Starting to wonder how much blowing we may have in the areas that got 3 or more "...if the snow has not melted a bit on the top.

Did finally struggle bus past 2” here (2.1”). Very light steady snow and 26ºF. Have to see if some of these meso modeled streamers set up around here later on this evening when the reinforcing cold starts settling in on NW flow. 

Most roads look decent. Yea, solar is a factor but it’s still pretty weak. Either way,  height of the day plus light rates makes it easy for road crews to handle (plus a boat load of treatment already on the road from a wintry week).

Looks like MDT is going with 2" for now...if their snow depth listing is correct.   

 

From latest CTP AFD

The upper trough axis (which may be slightly cut-off) will be
overhead tonight and swing to our east on Sat. The cold air
being brought in on the northwest flow will generate plenty of
lake effect and upslope snow showers. While the cross-Erie fetch
may be short Sat, there will be a pronounced Huron connection to
help bands survive deeper into the CWA. Several of the HREF
members bring at least one such long-lived band as far south as
Schuylkill and Lebanon counties Sat aftn. We`ve seen these
some of these over the years, but they are rare. Have allowed
for at least schc PoPs there in the aftn when instability will
be maximized and fetch most-favorable.
