The maps all over the news and nws are just wild to me. Listening to WIP on way to work people think we’re getting a foot of snow in the city. I don’t want to sound like a deb, because I am excited for the storm, but I personally think 4-6” then sleet for the city. I just feel like we’re going to hear “oh the wx forecasters blew it” all week. I just don’t see a path for Philly to get 8+. I hope I’m wrong lol. This event has reminded me of Dec 2020 and I’ll stick to that general snow axis. I said I liked that analog a week ago and now it’s top 5 in analog matches


.

I think there’s definitely a path. Hard to nail down that warm tongue and air temps are very cold. I personally think it was an off run from the NAM. If it does that again tonight and we see some trending, then I’ll worry.

The CGI (canadian goose index) just rocketed off the charts here. Must have had 300 or so just go overhead and i hear more coming. Couldnt ask them in time if they thought the warm nose was being over-modeled though. Still have to wait and see.

What NAM are you guys looking at? Still seeing double digits region-wide over at TT... What am I missing?

Did you see the post showing temperatures of the cold front coming in

Bradford Pa is at 0°

State college is at 14°

Went 10-16” for the Lehigh Valley on my page yesterday. Sticking to that tonight. We cannot have another jump north after that 18z suite though. That would cause me to really rethink things and I HATE busting high.

This is a good forecast. I think Mt. Holly has a good handle on this one. Its been a pretty stably modeled storm aside from 12z suite today. Also anybody see DT's forecast?

Is it possible to have both a warm tongue and suppression? This looks like a pretty close off solution that doesn't "redevelop" the surface low.

Think the budget was cut balloons too expensive so geese were tagged to sample the atmosphere around our region looking for where the warm tongue will set up.

We have an uncanny ability to steal defeat from the jaws of victory. So yes, there’s a world in which an arctic high can suppress precip, but what trace amounts bust through will encounter a warm tongue and fall as anything but snow. It’s how we roll!

Sorry for the non weather question.  I’m old and a widow so preparing.  Adam Joseph said don’t shovel the snow before it flips cause you’ll never get the frozen stuff off a bare walk.  Is he correct?

 

Just had a pretty good wind gust.  Cold front incoming. Wind chimes going nuts just now.

Surface map is showing the front has crossed the area and my dp dropped down to 6F within the past hour.  Am currently at 30 after getting up to 37 as a high with 18 dp.

Don't forget the premature ending problem. We finish faster the anyone.

Still thinking Allentown e.n.e. to n NJ is the jackpot with 16-20 inch potential. Expecting very tight snowfall gradients near PHL to MMU, amounts could range from 3" to 12" over relatively short distances (n-s) in that zone. Given the location of PHL airport its total may be considerably less than a lot of people who live in northern suburbs. I guess you are used to that anyway. I don't believe both the GFS and the NAM could be exactly right so the result will be some sort of compromise between them ... would go with 50-50 blend, then if ECM is not close to that, further 50-50 of the blend with ECM. By the time I had that worked out, I could compare it to reported totals.

Anyway, expect some very sharp gradients in this storm, and some thunder with the snow (or sleet) towards mid-afternoon Sunday.

If anyone is interested. The Joe and Joe weather show will have DT, Bill Goodman from Upton, and Alan Kasper on live at 735 PM
