jayyy

Surprised anyone here actually still tunes in to their forecasts tbh.

Dare I say it…. Actually pretty reasonable .

NBM blend has been rocksteady with what I’ve had in mind for this storm for days. It’s not always spot on, but it gives us an idea of what’s possible given the uncertainties we’re facing. This would be a win for pretty much everyone. I live in Carroll county so this isn’t an IMBY thing; I can’t shake the idea that the MOCO - HOCO deathband zone will likely do well with this one. Not buying the 3-4” depictions from some models. This setup has a classic look at 500mb for that area to do well on the NW side of the storm. Can someone remind me what models get considered in the NBM blend?

CAD all the way down into NW NC. Classic signature right there

I know it’s the FV3 RAP and SREF, but they’ve been pretty consistent on the due W to E nature of precip. Cautious on those though as we’re definitely outside of their useful range

Agreed. The area i’m most interested in as far as “boom potential” is the moco-hoco-bwi corridor. If models are underdoing the dual banding aspect, they could score some nice totals in that area where they stay all snow but are also far enough south. Going to be a nailbiter for sure.

00z tonight should be interesting. We’ll finally be within *roughly*24 hours of the onset, so hi res models will hold a lot more weight.

GFS / NAM locked in. Lets see the euro come in line by 00z tonight and were all systems go

Looks great

Don’t post all at once now [emoji23]

GFS essentially held serve. Nice to see it not go south. On to the next.

People have apparently forgotten both “thread storms” just last January where things looked bleak and south 48+ hours out, only to come back north… along with countless other storms that have not held serve 2+ days out over the years. It happens frequently. Does it mean it’ll happen this time? Of course not. Maybe Richmond does jackpot. But we’re talking about models waffling 50-75 miles per run based on small variations in confluence, vort strength, etc. This is largely noise. If someone asked me to bet on whether a storm (especially one with a re-developing coastal) is more likely to shift north / stronger or south / weaker inside 60 hours, I’d bet on a north bump 9 out of 10 times… unless there was some crazy strong high to our north (which there isn’t) Temps will be in upper 20s to low 30s so we’re not talking about the storm being overwhelmed by confluence to our north. History teaches us a lot. This may be one of those times where models continue south, but a compromise between the nam / gfs and euro seems most likely to me. Let’s see what 00z gfs and euro have to say, but this synoptic setup with a ULL pass to our south usually means solid snow for most of the forum

My thoughts exactly. I think Baltimore and points west are still very much in the game for big totals. Even the northern tier is still in it for warning level snow given temps and ratios. Tomorrow will be very telling. If euro continues to tick north and gfs / NAM hold serve, it’s game on

I’m off work on Monday. May stay down at my brothers in HoCo rather than up here in Carroll County for an easier commute to work on Tuesday (and in hopes of seeing a bit more snow honestly)

Baltimore jack on NAM wowza

I know many tend to hug the snowiest for their backyard, but a blend of all of the major OPs makes total sense for actual forecasting purposes. If GFS / NAM also go south tonight and euro holds serve, that’s when I’ll be a smidge worried for Baltimore & north. And by “worried” I mean 4-6” instead of 8-12”

Come to papa haha. Euro doing its typical waffle 48 hours out before trending back to its 3-4 day depiction? We shall see

I know it’s the SREF blend but this is what I have had in mind for days now. Makes the most sense to me based on setup and climo. We shall see though.

Agreed. Been beating this notion like a dead horse as of late but a split of the euro / gfs seems most likely, which is 6+ for most of us.

Still putting my jackpot in the general latitude of Leesburg to germantown to Columbia to Easton for now. Will see how things look by tomorrow 0z but I don’t buy the dc south jack quite yet. Euro has been known to lose things 48 out to get them back closer to game time. Can’t shake the general climo aspect to this storm, especially early on in a cold pattern.

Sure. But it’s an arctic front vs a complex storm setup. Not really the same thing.

I’d say predicting the precise location of isolated snow squalls is different than a full storm but…

That picture I took was on rt 40, Chatham station outside trilogy dispensary. Stopped there on my way home from work.

Just left work. It’s ripping out here in HOCO .
