CAPE Posted February 18 Share Posted February 18 Still discombobulated but it kinda works out this run. I doubt this is the final outcome(hopefully not) Looks like interior areas get snow associated with the lead shortwave as it sharpens- Eastern areas get snow resulting from the phase and the developing offshore coastal low. Precarious. 3 Link to comment Share on other sites More sharing options...

stormy Posted February 18 Share Posted February 18 The best thing I can say this morning is this threat is still 4 days away. Anything can happen in 4 days. Yesterday morning I said don't plan tailgate parties until Saturday. That applies again today. One big question to me has always been. Will the main action be tucked into the coast or too far offshore?? Yesterday, the Euro couldn't find the storm because it was half way to Bermuda before it really cranked. Things are a little better this morning but the GEFS is way out there. The benchmark for a big hit west of 95 is usually an east longitudinal alignment with Norfolk. South or even southwest is a different ballgame. Eastern folks can do somewhat better a little offshore, but this is too much for most. (Unless it changes) Always trying to be positive, I'm happy that my 7 model blend this morning is 2.1 inches. Link to comment Share on other sites More sharing options...

Charlotte got nailed Raleigh dry slotted and beach got blizzard lol The writing was on the wall early in the season. Like I said in December and several times since, you really want to be in the bullseye with the first threat. To the naysayers, NO...., it doesn't always work out that way (think 2007 clipper that put us ahead of Boston only to be our biggest event that winter while ENE did well.) But it's reliable enough to assume the area that does bullseye first will end the season with the highest snowfall anomalies as the pattern will tend repeat through the season imho. 1 Link to comment Share on other sites More sharing options...

You know us snow weenies...terribly vindictive! Lol Even if Weathernext2 is also off by one color, it would still be 6” at DC. I’d think 6” would be bordering on a “major” hit there considering that I saw a stat that only 0.7 5”+ snowstorms hit DC each year at this link meaning many years don’t even get a 5” storm: https://downloads.regulations.gov/FWS-R5-ES-2016-0030-0073/attachment_18.pdf#:~:text=For four days a year on average%2C,events that occur about twice a decade. 1 Link to comment Share on other sites More sharing options...

But it's reliable enough to assume the area that does bullseye first will end the season with the highest snowfall anomalies as the pattern will tend repeat through the season imho. There are patterns within seasons for sure. But some of this is perception bias and selection bias. For example...your theory this year only works if you ignore the first real snow of the season that missed up just to the north in early December and gave parts of southern/central PA 3-6". Of course places further north would point to that snow in November in upstate NY but do we toss that because the winter pattern had not set in yet? Then yes...later in December those 2 events hit south of us...but I got 5" from a storm during that period also. Which one is the one that becomes the real pattern setter? It's easy in hindsight but that is biased. I am not denying your point about patterns within seasons. There are real tendencies for a seasonal pattern to produce repeating results. In a year like 1996 and 2010 that's great for us. Most years...not. But the issue is...this isn't very useful for predictive measures because of 2 things. 1) You don't know ahead of time when the pattern is starting. 2) You don't know during the pattern when it's going to end. Every pattern breaks at some point. Right now we don't know if that is going to be with this next storm (hopefully) or maybe March or maybe the pattern lasts into Spring and it's too late for us by the time it ends...but without knowing when it ends we can't just say every storm is going to do the same thing. 6 Link to comment Share on other sites More sharing options...

NorthArlington101 Posted February 18 Share Posted February 18 It was touched on but this was by far the best EPS run for this threat. I'd buy the median right now. Likelihood of 3"+ also not too shabby 2 Link to comment Share on other sites More sharing options...
psuhoffman Posted February 18 Share Posted February 18 This was always a noisy setup with a lots of various SW's and phasing involved. Yesterday the timing and amplitude suddenly shifted with one of the waves and it changed everything. The euro was the closest all along to what everything else shifted to, with a stronger wave in the lakes on Friday/Saturday that stalls instead of lifting out. The timing of the weak STJ wave also changed and its running way out ahead on Saturday now, this is also influenced by the pinwheel in the lakes that wasn't there or nearly as strong on guidance until last night. But guidance is also trending towards a stronger inverted trough feature, also related to what's going on over the top of us. But those are really hard to pin down. With the trough hanging around and the upper low cutting off near us it wouldn't take much for this to come back if guidance identifies another SW to amplify. Most guidance just changed its mind with the wave that is now some weak POS on Saturday...it's not crazy if they find another little vort and say...ok lets amp this one up instead...the trough is there...the mid and upper level energy is there...it just needs something to come along at the right time to amplify at the surface. I want to see what happens today on guidance. 6 1 Link to comment Share on other sites More sharing options...
