Typhoon Tip

1/3 mi vis 7.25” S at the moment

People should put down the models and just like enjoy this?

S 4.25” est vis 1/3 mi 5F

Same here ... it's 'almost' S+ during a couple different intervals over the last two hours, but it quickly recedes back to a pedestrian S fall rate. Vis est 1/2 mi ... flirting with 1/4 mi when they occurred. Be that as it may, just under 4" here, so as expected ...accumulation is quite efficient in this cold air.

S/S+ est vis 1/4 mi 2.75" 6 F

Clearly a CF dump axis from PWM to ORH there... The other max is terrain enhancing.. whether that actually happens, notwithstanding

Better growth coming down now. Instead of cryo fog-, it's S- with actual discernible aggregates, albeit on the small side

I just keep musing tongue-in-cheek over how 6 days ago, we were looking at this continental mauler storm affecitng everywhere but here... Then, 6 days later... while it certainly is affecting a lot of the country, it actually appears to want to max where it was 0, six days ago - squarely right here in SNE that's an interesting model saga

There's an interesting phenomenon going on amid the Arctic domain right now associated with that crazy -AO depth ... which I suspect very few if anyone at all in here is aware. There's registering of record warmth going on up there. Quite highly correlated to -AO index modal states: it is warm ( relative to climo, of course!) up there, and colder at middle latitudes. This cold outbreak was be-a-utifully relayed from that crashing -AO, circuited through a -EPO...now, the EPO collapses and relays into the +PNA. The storms should be line up...but the models are taking a coffee break on seeing much...different issue/digression. In the meantime, some station up there...I'll try to find it, but in the midst of the 24 hour darkness, close to the N pole, in January, they were 36F ... That's like us being 122 in July.

heh right. You know, it seems unjust, or out of place, doesn't it. But I've seen huge < 10 hour turn around enough times that I've just come to stop really associating the scalar temperatures at onset with any kind of presumption. I've outlined the following event before. It's an extreme case, but in Jan 1994 we had a day dawn at 9 F throughout NE Mass... There were a few renegade flakes flitting down under the street lamps while the morning's ambiance of winter blue-gray twilight surrounded. By noon it was 24 with light IP... By 2 pm, light freezing rain at 29. By 4 pm, 36 with the evening dusky sky having transformed into then fast moving streets of clouds, S to N.. In a whoosh, front's through and by 6:30pm, it was 60 F with tree leaning monster S gusts. Now, this bears 0 synoptic relevancy to that. Different universe of events, entirely. However, the principle of believing scalar temperature means jack shit, is a very good one to remember. Haha. To this day, I really don't give a ratz ass what the temperature at the onset of x-y-z. I just understand what the chances are for things to happen after the fact, and go with it.

Vis est 2 mi; steady S-; very very small "micro aggregates". 6 F

Yeah... seems a little hard to believe, given the heavy suggestion by the indices through the first third of the Feb, but excluding the AI types all models carry nothing - However, you know a 15 to 20" regional snow bomb ... We can probably count on one hand over the last 200 years of weather history and yore, the number of times multiple 20" fell less than 10 days apart. I guess just based on that, which admittedly is operationally meaningless for deterministic weather forecasting in the dailies/now - more of a principle argument. We really shouldn't get a storm very soon anyone unless it's pedestrian and not asking the atmosphere to load up with more than Earth can provide in too short a turn around - the main reason why that is probably all true.. We'll see... lacking parameters doesn't appear to be the issue, though. The local hemisphere is in a higher than normal energetic regime. It may just be that we're stuck with ton of neggy interference. Because from orbit, it doesn't seem like there's a dearth of possibility when in a flexing +PNA, 570 dm thickness lurking near Miami, while it remains cold/cold enough in the OV, either. Lot's to consider

yeah, but the storm is going to wildly bust on the short duration side given to how fast it's accelerated, huh

That's why my jack for this is like Danvers down to Concord Ma... When those bands get on shore ... perhaps 5-7" of impossible to entangle OES bursting will be taking place underneath an already dense falling shield of micro-aggregates. Add that to the synoptic signal...

Heh... crazy having this be the antecedence to any storm. Hearkens to the rareness of this whole thing
