MN Transplant

Everyone is appropriately focused on the precip chances, but the temperature trend is looking like it will be unusual.  The core of the cold sweeps in during the day Sunday and we are in deep winter by evening with temps somewhere around 20 and breezy conditions.  But then the airmass begins to moderate and we flatline overnight into Monday.

Southern end precip getting cut back as models home in on clipper transfer and coastal pop. Trend has been drier for DC south along 95 but if I get a dusting to 1” I’ll take it and quietly wish it was more

I think we're semi-cooked on this one.  It just frankly doesn't snow for very long on any of the models and it isn't like this is a juiced up event.  We'll try again in January.

Love the euro for MBY

Forget north/south, it is 95 vs everyone else

16.0.  This is a cold December so far.

Thank you Washington for the confidence-builder for McCarthy.  I still doubt he’s the guy, but it is good to see.

That bridge shot is fantastic

.05” seems unreasonably low?

Glad you posted this as I came to check what others were getting SLR in the DMV region. Friend (who's also a met) from Leesburg sent me this a bit ago:

"So I measured a measly 0.04" of melted precipitation at 845am, and another 0.01 at 1pm. So I grand total of 1.7" from 0.05". I felt like it doesn't make sense so I measured the melted precipitation from a core sample off the deck that was around 1.25 to 1.5" and it was just above .03", so I don't know ha"

Seems like some real fluff up there today

Lol, I did the same thing.  I only had 0.08" in my CoCoRahs gauge which is usually dead-on when it isn't windy.  Then I took a core sample and only got a little more.  I think I'm going to go with 1.8" on 0.09" precip for a 20:1 ratio.  So, we busted low on precip but it didn't matter.

1.2”.  That band was excellent.

0.5” in McLean. FCPS shoulda cancelled 

Loudoun made a late call to close

0.2” and partially snow covered roads/sidewalks.  Flake size now increasing with that yellow band hopefully incoming.

Almost a quarter inch QPF in DC.  Even lopping off a third for, well, NAM, that still gets you in the 1-2” territory.  Looking good.

Parent NAM looks good, but the 3km isn’t playing ball yet.

18z Nam's a wreck.

I think we're better off if the 12/5 threat fizzled and left some energy behind for our next long shot.

Less than 48 hours away and we have the NAM 3k with no accumulation north of Richmond and the Euro with 0.3” in NYC.

It was never really going to snow here, so I’m pleased with the solid precip performance.  A good chunk of the area in the 0.75” to 1” range.

33.1 and rain.  Truly a gross combination.

Temp is bouncing around like crazy at Dulles.  Seesawing from 27 to 34.

To be fair, it doesn't show on mobile unless you go into landscape mode.

34.4.  HRRR basically has it correct now, but the 18z was too high and the 18z NAM was way too high.

Light sleet in Falls Church.  34.7

Know this is not going on here. But found a live stream of Chicago O’Hare airport. The planes landing in nearly white out conditions. Can see all the snow plows on FlightRadar24. ATC is hopping. 

I’ve never noticed the ground vehicles on the app.  That’s amazing.

First person to say “the ground is too warm for accumulation” gets insta-banned 

I’m gonna go with, “we need the rain”

BWI:  10.2"
DCA:  6.7"
IAD:  12.1"
RIC:  5.5"

Tiebreaker (SBY):  5.8"

Hit 70.0 exactly.  Really nice out.
