Unless PSU and Showme eat it all up

And I am hungry. :) eta: And I mean it. I could go for some eggs and bacon right now. Well bacon mostly.

Kind of reminding me of a thunderstorm rolling in here. Clear skies beforehand with a bank of clouds that just moved in overhead. Several gusts of wind came in as well. Just waiting for the snow to start falling at this point.

For many people(myself included) that were in the DC S&E areas of I-95 this one wasn't as fun as other near miss snows.  Again, the concern some had yesterday morning about lack of clouds and sun was warranted.  I'm not sure there were as many model runs that had DC and other places absolutely torch prior to the onset of precip.  If it was a few hours faster like the people in SW VA benefited from then I bet all of us would be rejoicing.

I started the morning at 28F prior to sunrise.  By the time precip started it was 46 IMBY.  That was just too much 925s to overcome.  It didn't flip for me until after 2pm which for many it had been ripping for hours and mainly had the luxury of temps helping. 

I understand location and climo.  Probably more than most of you.  So when models had my area for 1" or so I always know the challenges.  What grinds most of the gears for the people who see less snow isn't that we don't know what the odds are.  We just don't need that one extra thing to make it that much harder to get snow.  Yesterday was soaring temps.  That clearly delayed the flip.  Once I did I still had temp issues of only getting to 33F.  So it was mostly white rain.  Despite that, if I wasn't battling 40s at the start I would have seen a few more hours of snow even if it melted.  Thats what most of us wanted.  Just to have snow falling.  

So I got .5" yesterday.  Not just because of location and elevation.  Those are constants.  Yesterday's lower total was due to clouds not getting in soon enough, temps soaring, and the column not being able to overcome it.  

When I lived in Lake Ridge these events would drive me insane. The final straw was a driving rainstorm in Woodbridge when Leesburg reported 7" of snow...that's when I made my decision to move here in 04. My short stint in Nokesville was very similar. That said today's climate is making Leesburg pretty close to marginal now...I can see in a couple years the rain/snow lines moving further NW

I'm getting a late start this morning so I'm still home and decent snow shower rolling thru atm . I'm headed to northern Harford co so hopefully it follows me:D

Nice snow squall moving through here now. Great rates (better then what I saw yesterday that had some very good rates) with snowflakes reaching half dollar size. Probably have picked up close to a half inch in the last 15 minutes.

It's coming down.  Similar to yesterday around 5pm. Probably 1/4" or so

It's hammering here right this second. Probably one of the better snow squalls i have seen in a long time. Some gusts of wind thrown in as well. Wouldn't be surprised if I can pick up a quick inch or two when I look at the radar.

I will move in a few years.  the only thing keeping me where i am now is job and kids.  But in a year and a half the job thing disappears(as in my current one) and kids will be close to HS age.  Def need to get away from this UHI shithole.

I feel your pain. I used to live off Franconia Road and experienced a number of times these marginal events that come at us from the sw. Wind direction aloft is important for these types of storms. Had it been coming up the coast, obviously a much different outcome for your area. Keep the faith; Feb. will be your month.

Yes.  Coastals and cutters pose their own problems with warm noses and so on and I've had that happen a lot.  This one was def due to temps on fire before clouds got in.  i still would have been happy with snow falling during 80% of the storm as opposed to 50% even if my totals were the same.

Yeah, me too. At my advanced age, I'm more into watching it fall as opposed to driving in it.
