87storms

You’re one of my key upstream weather obs in this setup lol. Brunswick, too.

That is nasty stuff. Can’t imagine how many power outages there’ll be and a cold week ahead at that. Not ideal.

I’m not sure people realize how serious it is to be flipping to rain when it’s 15 degrees out. I really hope that doesn’t happen up here.

Yea, it’s unacceptable lol especially in January. Gonna just enjoy it while it lasts. It is what it is.

Gotta love having to worry about a sleet line when it’s 14 degrees lol

Better rates have entered Frederick. Looks like I flip to sleet around 10-11am, give or take.

Still snowing there in Frederick at 18z. The Catoctin’s at 1500’ are gonna get rocked.

Just a bit of a moisture fetch: https://www.star.nesdis.noaa.gov/GOES/conus_band.php?sat=G19&band=08&length=24&dim=undefined

The sailing thru winter solstice boats at Carroll Creek are gonna look pretty cool after this event.

It’ll nudge south and colder. I’d put money on it…but I won’t because I actually really don’t know.

I have no doubt our corridor gets 6–10” before the flip…and probably pretty easily. Every flake will count in this airmass.

Skiing in this weather takes dedication.

Yea I’m actually dealing with a sinus cold that came on 2 days ago so I periodically crank up, but overall I’m kinda bullish imby on this event. Battling a sleet line in these temps is objectively dumb, but it’s still gonna snow and not just a wimpy one.

Oh the sleet line is incoming lol (damn near every model has it) but I think we dominate the initial round. This airmass is brutal. I’m not playing basketball outside today and that says something.

I need an iced tea tumbler version.

Idk…I think our areas are gonna get off the schneid (the wizards are another story). Good ratios will save us before the pingers arrive.

Those are pretty minor ticks tho lol. I think that mid level warm air punch could still be over modeled. This is a professional airmass it’s up against. We’ll see soon lol

Gfs looks like 0.75” minimum in Frederick before the sleet line encroaches up 270.

For those that haven’t ventured outside yet (eg, you don’t have a dog), it’s a legitimate ice box. I’m gonna say it now…the nam is full of ish. I’m going with the euro.

We’ve reached the armchair psychologists part of the storm tracking game.

Yea but the issue seems to be more about amp instead of de-amp. Regardless, this storm is annoying. Under absolutely no circumstance should we be worried about sleet when it’s 10-15 degrees out at start time. We’re just not that good at this game, but it is nice to at least get a thump before the correlation coefficient posts go ham.

This is just preparation for the miller B on Thursday.

I want to move this panel southeast by 75-100 miles: https://www.tropicaltidbits.com/analysis/models/?model=nam3km&region=us&pkg=z500_vort&runtime=2026012412&fh=30 I’d roll with the euro for the sake of cad, but the problem is clearly the track/strength of this low. Nam just slingshots that residual Baja low into West Virginia. Can see it on the 500 loop. Kinda surprising that we couldn’t have a more entrenched hp in place given today’s Siberia style weather. Guess it’s a nao thing. Still generally like the idea of 4-6” minimum for most, which is enough to cover grass blades (a crucial rubric in grading snowstorms).
