Newman Posted November 13, 2018 Share Posted November 13, 2018 Sun angle in November is pretty low so that's good. Temps will be down into the mid-upper 20s Wednesday night and Thursday morning. However, we might lose a lot of our initial precip to virga due to how low the dewpoints are. Link to comment Share on other sites More sharing options...

Tucked low, no blocking hp North to cause a redevelopment or bump East, no HP to the North filtering in LLC. Outside of far N and W higher elevation areas this is just a teaser....something to track to get the rust off. As far as the ULL pulling through early Friday with a death band I suppose it's possible but forecasting this type of scenario at range is a real challenge. Hoping to maybe see a few flakes at the onset and maybe a few flakes Friday anyway. Not expecting any accumulation in my area. Eta: There will be the first accum snow of the season for some, just wanted to note that my disagreement in snow vs little to no snow is irt the i95 corridor and immediate burbs. Far n and w ftw my thoughts exact and imo this is the type of storm that will be common this winter. Link to comment Share on other sites More sharing options...
The Iceman Posted November 13, 2018 Share Posted November 13, 2018 I don't like this for anyone S and E of Quakertown area. Not a great setup in the heart of winter for the coastal plain, let alone mid november. I would be shocked if anywhere S of Qtown sees anything outside of a slushy inch. Lehigh valley though, this may be an all time fall snow storm... Link to comment Share on other sites More sharing options...

Exactly and thus why I'm not overly concerned with my winter thoughts/outlook post. Yes...active storm track. Yes, ample moisture. Yes, El Nino. BUT you cant just assume this means plenty of snow. My analog winters had all 3 of the factors I noted above but ended up with storm tracks similar to what we have seen so far this fall and with this upcoming storm and yielded not so much snowfall in the city after hopeful late fall starts. We can only hope the track shifts as we get deeper into winter....if u like lots of snowfall in Philly. Otherwise a frustrating season is coming along I95. Hoping we r wrong Iceman but I would much rather be conservative in this pattern than go all-in with a monster snowfall season. Far interior should do really well tho.

Newman Posted November 13, 2018 Share Posted November 13, 2018 This map is more realistic: Still, it's literally mid-November and we are tracking a legit snow/ice storm. Anything to cover the grass is a win for me. Link to comment Share on other sites More sharing options...
The Iceman Posted November 13, 2018 Share Posted November 13, 2018 The 3k NAM is at range but shows probably the worst possible solution for 95(or best depending on your outlook). Big thump arrives in the late afternoon and lasts through the evening commute before changing to sleet then rain. May not be a prolific total maker but it's timing is for maximum impact during the evening commute. One thing to note though is that while low level cold may hold on longer than expected, the upper levels tend to torch much quicker than progged in these systems. I bet most of what the NAM is showing as snow in 95 corridor is actually sleet and the changeover to sleet will be much faster than advertised. Still a quick 1-2" during the evening commute could wreak havoc especially since most won't take it seriously since it's November. Link to comment Share on other sites More sharing options...
Ralph Wiggum Posted November 13, 2018 Share Posted November 13, 2018 Looks like 12z suite so far is a bit more tucked with the slp just inside the coastline and thus slightly warmer. Looking more sleet than white here and for many. Agree with Iceman above quick thump with a relatively quick transition to sleet then slowly to cold rain for nearby NW burbs. Temps right around freezing up in my area of Bucks. Glad I'm off Thursday :-) Link to comment Share on other sites More sharing options...
The Iceman Posted November 13, 2018 Share Posted November 13, 2018 BTW does anyone know how the parallel GFS(at least I think that's what FV-3 GFS on TT is) has done so far and when it is taking over for the GFS? It's running now but not sure whether it is worth looking at or not. Thanks. Edit: looks cooler than the OP GFS for 95.. definitely at least starts as snow where as OP I think most start as sleet.

RedSky Posted November 13, 2018 Share Posted November 13, 2018 These tucked solutions won't get it done in November. While somehow they have managed to bring snow to the coast in recent years it's not happening with the still warm waters. Link to comment Share on other sites More sharing options...

KamuSnow Posted November 13, 2018 Share Posted November 13, 2018 Meanwhile, got 2.3" of rain overnight and early this morning. 4.9" for November so far. Currently 46F and cloudy. Link to comment Share on other sites More sharing options...
RedSky Posted November 13, 2018 Share Posted November 13, 2018 Surprised nobody mentioned the ECM. Still shows a significant snow event in PA to Philly and 3" in eastern Monmouth here. The americans are mostly rain. Tucked to coast vs not as tucked. Link to comment Share on other sites More sharing options...

I have to side with the americans as of now based on the ECM performance last winter, it kept going hog wild with snow last winter who knows if it's been tweaked or not.

The Iceman Posted November 13, 2018 Share Posted November 13, 2018 18z NAM def took a step towards the Euro...cooler than 12z...actually a decent thump..decent meaning 1-3" with 1-2" being most common...but N and W burbs...not too far from a potential warning event....

It's only mid-November and we're tracking THIS. Check out the 700 fronto on the NAM. We all will be thumping heavy snow during the evening commute Thursday.

Wherever i go the gosh darn fence will follow me. Don't worry about the snow maps with this storm. The NAM shows 1.25" of liquid for a lot of SE PA. At 10 to 1 that's 12" of snow. Ratios will be 8 to 1 so make it 10 inches of snow. Cut it in half to account for sleet and you get 5" of snow and almost 2" of sleet and/or freezing rain accretion.
