2/6-7: Clipper Pack Refresher

[wxmeddler]

I have a small bone to pick with LWX:

Quote

A strong low pressure system located offshore paired with 
arctic high pressure moving in from Canada that yields a very 
tight pressure gradient across the area. A strengthening LLJ at 
850-925mb that crosses the area Saturday morning will support 
the mixing of stronger winds down to the surface.

PGF driven CAA does not equal an LLJ! LLJ's are either nocturnal boundary layer decoupling driven events or cyclogenesis driven ahead of a cold front.

About a tenth or so of pixie dust snow at home. More fell where I was in Owings Mills

We got a solid coating here. Close to an inch.

M0.3" at my house. About a mile east of where you were.

Seeing a few lightning strikes and ASOS stations reporting VCTS with that band coming into PA right now.

Was just looking at that. GOES GLM is showing a few strikes with the leading edge of the polar front. Wouldn't be surprised if it's picking off antennas or turbines.

KHZY reported VCTS earlier and I thought it was spurious too. Then KUCP picked it up and made me double check. Most of the lift and buoyancy is embedded in the -10 to -20C layer, so seems possible.

I may have worded that wrong. I mean that the lightning is picking off (ie. hitting) antennas or turbines, as is common in winter time events. Like the lightning has a choice in what it hits. . I have absolutely no doubt that lightning is actually occurring.

Oh gotcha! 

Yeah, looking closer -- there's some nice mid-level DPVA superimposed over that surface front with the left exit region of that jet streak nosing in aloft. Good spot for something to happen. Hope it makes it down to at least our northwestern folks. Been a while since we've had a good arctic front driven snow squall.

I don't know why more people aren't in here. This is very exciting and rare for this area meteorologically.

Prob because we are unlikely to see anything but cold wind... which we do really well here. But I'm with you it is fascinating. You think there's any chance we see a squall from the frontal passage E of the BR?

Weenies gonna weenie - a lot are just here for the snow.   

Agree this is pretty rare for our area, we got about an inch of fresh powder on top of the snowcrete - super cold temps - deep winter around here, plus some interesting dynamics to watch tonight. Really can't ask for better. It will be like Antarctica for a few hours. 

[caviman2201]

Definitely going to be watching the Wisp cams (https://www.wispresort.com/mountain-report-cams/) as that squall moves in from the NW... should be pretty epic

This is also one I like to watch up in the DCL area: https://www.youtube.com/watch?v=7cfGy_FAYhk

 

[MountainGeek]

Any guesses on how far east the squall is going to get? 

[NorthArlington101]

I only care if it’s gonna make it. Is it gonna make it? Do I set an alarm?

[jayyy]

Drove through a few squalls / snow showers in SWPA on the way to our friend’s house in Ohio. Nice scenic view driving thru the mountains with snow falling

[Nomz]

Very pleasantly surprised on the snow today, didn't think it had the juice to get all the way to DC. Pretty solid flakes for what was basically a flurry.

[The Dude]

Ended up with about .4" in N. Bethesda

[WEATHER53]

Where is the front Countdown ?

chime in please 

[LordBaltimore]

Need this squall line between hagerstown and frederick to hold together over south mountain

 The Polar front? Most definitively, the snow squall up in PA?... eh.. maybe a few flurries.

we're getting 500:1 ratios. moon dust stuff. We only need like 50 flakes

[Nomz]

Pretty extreme wording for tonight

 

[MillvilleWx]

Legit SN+ on top of Keysers Ridge before the squall. Reports upstream were 2-3” in 45 min. This is gonna be wild.
