That matters a bit too, of course, but it's not April yet, so I think more than half will still be around and 90% in the shade - and I happen to live on a shady property (across from Tommy's Pond if you know Metuchen).
-
Why so low? NWS has you getting ~2" of dense snow/sleet (0.4" QPF as snow/sleet, so ~4" of snow worth), then 0.1" of ZR which will be absorbed into the pack. Do you think they're going to be that far off?
-
100% yes, assuming we get ~0.5" frozen QPF (and especially if it's mostly sleet, which melts more slowly than snow), given highs in the upper 30s Sunday and Monday and cold nights
-
Keep forgetting to post this for giggles... Last, but not least, my guess for my house in Metuchen is 1.5" of snow, then 1" of sleet (~3" of snow equivalent in that sleet) for 2.5" snow/sleet on the ground, then 0.1" of freezing rain on top. We'll see...
-
Thanks, this is great insight. Is this 1000-850 readily available? And what's it telling you for, say, my house in Metuchen - or at least in general for the 95 corridor/NYC?
-
Question if you don't mind: how much do you use the 1000-500 mbar thickness 540 line "rule of thumb" for divining the snow/rain (or mix) line? I think every model has the 540 line along/N of 84 when it's precipitating, even the snowy HRRR.
-
People need to stop with the "nil" comments from the NAM - it showed 5-6" of snow as sleet, i.e., about 2" of sleet. That's pretty damn impactful if not pretty.
-
Don - I assume the HREF is showing just pure snow correct (like Pivotal does)? Also, is this available free somewhere? TIA.
-
Found this to be interesting...hadn't noticed the snow depth before - assuming that is sleet where no "snowfall" is shown on the regular map, since Pivotal doesn't show sleet, per se.
-
6" of snow or 6" of snow as sleet, i.e., about 2" of sleet - not nothing or even close to it - still very impactful, but not as pretty. Here's the 12Z NAM for EWR - mostly sleet topped off with 0.1" of ZR. Ugly. http://coolwx.com/modelts/images/nam/current/KEWR/prec.png

Yes, it's really been good on tracks, plus the 6Z GFS bumped significantly back NW and the UK is a moderate hit for CNJ/NYC and SE of there where it's a big hit for Philly/SNJ. Doesn't have to shift much NW to put everyone back into at least a moderate, 2-4" event. AIFS precip is below and all of that is snow given temps are below 32F for the duration, except for SENJ. Would likely be >10:1 ratio too.
-
Agree those are very likely high, unless the HRRR scores a reverse NAM coup, lol
-
The updated NWS maps for snow/ice are below and show a bit of an increase in snowfall amounts for the NWS-Philly counties from Sussex down through EPA/CNJ vs. yesterday. Note that other media forecasts show more snow/sleet than the NWS (News12/TWC) and some have similar amounts (Channel 4/Channel 7; I could post them if people are interested, but I thought they were frowned upon here. Obviously a very tough forecast with 1" per hour snow (or the equivalent amount of sleet) falling over 5-6 hours, so when the changeover occurs (for those who change over) will hugely impact how much snow vs. sleet is observed; and most look to get maybe 0.1" of freezing rain at the end; also, the sleet/snow will all accumulate at night with temps generally at or below 32F for the storm. And there are models with mostly snow and little sleet vs models with mostly sleet with little snow and everything in-between so good luck to people who forecast for a living. No matter what, at the end of this storm for most in this forum, there will likely be 0.5-0.7" of frozen QPF on the ground (even the freezing rain will simply be absorbed into the snow/sleet pack) which is substantial, so impacts on driving will be significant regardless of how much snow vs. sleet and it'll be a heavy shoveling.
-
Changing the topic is a sure sign you have lost the argument. But for the record, at 1 am this morning on a model summary post I said "we're nearing consensus on a 3-5" event between 276/195 and 78" and was referring to model consensus, which was absolutely true based on last night's 0Z model runs where every single model most look at (GFS, CMC, Euro, UK, ICON, NAM and RGEM) had 3-5" for that area. It was not a forecast and I seriously questioned that model consensus this morning after seeing the 6Z and 12Z NAM showing a lot of sleet.
-
Ridiculous post since tomorrow's event hasn't started yet and its outcome is unknown. Could be a sleetfest but could also be significant snow for the City or somewhere in-between.
-
Gotcha - was just curious what you were referring to as it wasn't obvious. I was also surprised by the watch, which was pretty early.
-
That GFS run shows about 1.5-2" of sleet when comparing the Pivotal vs. TT maps.
-
More trolling. You do realize it'll be Saturday night when a ton of people will be out and about, with some probably drinking, so there will still be plenty of accidents, especially if people think it's a "non-event" plus how will roads magically be "fine" Sunday morning with ~6" snow equivalent on the roads (it will all accumulate at night with temps <32F) and temps not going above 32F until 9-10 am?
-
Are you just trolling, as is your habit, or are you going to really try to convince people that 1" of snow, 1-2" of sleet and 0.1-0.2" of ZR is a non-event? We saw significant impacts yesterday from 1/2" of sleet for most and this would be about 4x as much frozen QPF otg.
-
So, you're saying 1" of snow then 1-2" of sleet (3-6" snow equivalent) and then maybe 0.2" ZR is a non-event? Sure, it's not a lot of pure snow, verbatim, but we're still talking about 0.5-0.7" frozen QPF on the ground (the ZR will be absorbed). Pretty sure your neighbors will disagree as would most posters here.
-
Huh? No obvious changes - care to fill us in?
-
Still no NWS-Philly AFD - wonder if they're reworking things to align better with Upton, which would mean bumping snowfall back up for most of the area...
