Another very gusty afternoon it looks like coming up this Tuesday w/ steep 0-2km LRs and 1-2km winds into the 40s(kts)... at least on the HRRR. Got to imagine that other CAMs are fairly similar. 

Assuming we don't go below 26F at IAD before midnight the high/low at IAD for today looks like:

48/26

Today's average at IAD:

47/27

+1/-1

Perfectly balanced... as all should be.

So on a technicality it wasn't really a clipper?

Not the classic kind that people are referring to with a 50-100 mile wide strip of light (sometimes mod+) snow oriented from west to east across the region associated with overrunning and/or a jet streak, no.

Thought that was February that year? (I remember it happening on V-Day unless that was another one)

January 6, 2015 is the one I remember well. V-Day 2015 was everyones favorite snow squall(s) of recent times. Well the associated shortwave did enter the US from near Alberta but the strongest forcing by far came along the arctic front.

So IAD gusted up to 50kts(58mph) late last hour.

Winds: NW 33mph Gusts: 58mph for the 5pm obs there.

Sharp fropa in Gaithersburg. 

Event of the year thus far...

HRRR actually has 1km winds into the low 40s (kts) (~50 mph) tomorrow afternoon w/ CAA behind the front. Perhaps we get a Wind Advisory?

Still 65/41 at IAD at 8:29pm.

We bust harder with wind then snow in these parts.

Severe wind...true.

Wind strong enough to be a nuisance but too weak to induce adrenaline... that's constant.

Most solar production today since October 18. #sunangle

It's definitely becoming noticeable how much higher in the sky the sun is now at solar noon than it was in December.

2.16” here in ashburn. 

temps hung around 36-39 the whole time. 

with a proper cold air in place and the same track, this would have been 20 inches. 

But despite the cold surface temps, this wasn’t even close. Even if the surface was below freezing, it would have been ice given the airmass. >32 isotherm all the way up to 700mb.

So this was nowhere being close to a snowstorm without a 50/50 and a much, MUCH colder airmass.

Wow. Over twice as much as the 1.01" IAD recorded. The band must have set up just N and W of the airport over you.

Woke up this morning. Don't believe what I saw! Hundred billion snowflakes piled up on earth's floor! I'd never know it being asleep. Hundred billion fallen away searching for a surface!

Woke up and recorded 0.5" here. Herndon, VA.

Starting out cold, dreary and with a little bit of white?
