  1. Couple of notes: I think there is a national weather models comms problem. GGEM/GFSV16 seem delayed. RGEM is in through 00z/Monday. Could b e a lonnnng slow wait for snow to arrive... wouldn't rush it. Go with I80 Monday morning at the latest, but possibly not I90 til Monday evening? LONNNG ways to go.
  2. Here are some GEFS 06z/28 plumes for LGA... use with caution but you'll like these. No consensus in this data yet except 850 and sfc temp. On the qpf and snow, try to refrain from buying into the extremes above the mean axis and think a little more conservatively. Avoid disappointment. I won't post other ensemble guidance since we're into a new 12z cycle. in order of appearance: QPF, sfc T, 850 T, type (like to have 80% for assured all snow), snowfall which is all over the place.
  3. You're very welcome. I might be too strong on the posts... but I just try to cut to the chase.. lots of life can go over the bridge if too involved. Not an excuse, just a reality that I try to keep in mind. That said... Nothing different from the posts. My guess is 6+ with heaviest n of I84 but that differs from WPC so take me w grain of salt and let's rereview late today on the primary thread. Also, pay attention to the other posters here and elsewhere who see negatives. I try to be conservative but push. Still plenty of uncertainty and yes, I can see only 3" extreme nw NJ and se NYS if half of this is sleet.... I do think we'll get to 6 before any sleet mix. I can't see "ensemble" EPS GEFS soundings with the access to data platforms that I rent now, so that's a disadvantage. I make lots of presumptions from the datasets that I review, and maybe too HASTILY. Later, Walt
  4. fwiw... fluffy large flakes of snow here in Wantage NJ 925-938A. still ongoing. won't be surprised at dustings beyond the Poconos next 24 hours ending Noon Friday before its too cold and dry. Hoping we can muster 0.2" tonight here in Wantage NJ.
  5. Here's the EPS cyclically ending about the same time (4th) 10x1 snow ratios inclusive of sleet. The runs prior to the 27th included snowfall for the previous storm north of I80 but I think you can see the EPS consistency, so far. I think wherever you evaluate the consistent centroid axis, that's the safest for 6+... with greater variability and potential for disappointment along the edges (I95), Adirondacks-n VT on the nw side (Comma head deformation banding). Also, fwiw... while its snowing in NJ late Sunday or early Monday, folks east of Hudson may be wondering when the snow arrives as its turn to the northeast may be a little slow and dry air devoured. Latest is first (00z/28). and proceeds backward sequentially in time.
  6. Thanks to all...keep adding your views-models. I and models to date may have EASILY missed something. I myself think I80 in NJ even Sussex County should be a little concerned about sleet but otherwise, there is little doubt something that will need snowplows/blowers is coming to a fairly large part of the area along or nw of I95. Did anyone notice Kuchera halving the snowfall for the valleys (partly downslope shadow, partly slightly warmer valley temps). If some of these EC temps are correct, we're talking snow ratio's dropping under 10 to 1 all of NJ after the initial few hours of snow-sleet. By the way... to those who maybe were dissappointed about only 1-2" of snow on your driveway-sidewalk on 1/26-earl;y 27. Hope it was shoveled/cleared yesterday, cause if not, it's with you as a slippery surface, probably through at least Thursday morning Feb 4. That's another reason why advisories sometimes are of value...they trigger thoughts about clearing snow from paths etc. I digressed but hopefully with a little added value. I'll post the runup of EPS ensembles very shortly. Enjoy the wintry feel. I love it, as did my energetic dog on his morning walk.
  7. 612AM/28 headline update: added 6+" to the headline, best chance nw of I95. By 830A will add the multiple cycles of EPS supporting guidance. Overnight WPC D4-6 guidance still less than ideal but does not include much if any of the 00z/28 ensembles which are heavier than what is added here (hopefully correctly trended model guidance?). There is a pretty good chance of eventual rain involvement on or just se of I95, but the front end of this Nor'easter should produce snowfall for the entire area before a possible mess. Not a beast but uncertain potential for a major snowstorm (1 foot+) for part of the forum, probably closer to the I84 corridor or even north of there. Let's enjoy the ride there and appreciate whatever we get-this sets my rain concerns about the I95 corridor southeastward. Max gusts still seem near 50 MPH a part of LI and maybe the NJ coast. There is potential for minor coastal flooding with the Feb 1 high tide cycle-fortunately not astronomically high tides. Added graphics are WPC D4,5 3"+snow graphics, there total qpf forecast (seems a little low but has to be considered), the EPS base 10-1 snowfall (multiple successive cycles almost identical) and the GEFS prob for >6" of snowfall which focused my concern for rain/sleet I95 sewd.
  8. I didn't double check... CoCoRAHS. I have to accept. Might be higher terrain?
  9. KU top 10? I'm not thinking this, nor a beast but a snowstorm seems ahead for parts of I95 corridor and probably inland. Some signs of development a little too late. GEFS/GEPS have a good snow event but a little concerned about GEPS/GEFS/NAEFS offering only a general 0.4-0.8 qpf. Could be too low and undoubtedly there has to be accentuated snowfall on the inside edge of the comma head, wherever that may be nnw of the closed low. Adding a bunch of guidance: WPC stat prob of 3+" in subsequent days. Back tomorrow morn.
  10. Can't keep up w all the posts. Old news and comparative non-news. NYC CP coldest since Feb 1 2019 seems possible/probable Saturday or Sunday morning?? About 12-13F? May be preceded by a narrow band of squalls early Friday (prior to sunrise?), especially se NYS/PA/nw NJ. Lots of hazy white virga all day Friday per cold pool aloft: Northerly flow after secondary CFP early Friday leaves this dry sourced and unable to get more than passing flake to the ground during the daylight hours?
  11. CoCoRAHS summary posted after 930A/27 for the northeast USA. I thought this had a decent "initial" 19th issuance handle on the widespread wintry event (north of I78) which occurred predominantly 10A/26-5A/27 (was initially too fast by 24 hours). Models were not far enough north on primary qpf axis and heaviest snowfall (I90 widespread 4-9") since the short wave appears to me to have been stronger and further north. midway into the event daily runup. Snow predictions on my part were wayyy too high. Essentially this was a widespread 1-3" event north of I80 to I84 where it transitioned to 2-5" event in far northern part of the NYC subforum. QPF was less than modeled along and s of I80 and and a little heavier than modeled I84 northward. Snow ratios less than 10 to 1 s of I84 where mixed pcpn and I think 10 to 1 or a bit higher to the north of I84. NYC recorded it's first snowfall of the month. Yes exceeding minor but it all counts. So the topic worked okay but the amounts were too high due to northward translation of the short wave. A disappointment for many but for me, I see this as another successful synoptic scale event flagged again 6+days in advance, by the modeling. The overall modeling continues to improve. Thats the researchers/data platforms/computing power that make this happen.
  12. CoCoRAHS summary after 930A today: snowfalls from n MD (sleet/snow) through the forum to northwest of the forum. Also forum water equivalents.
  13. Model runtime logistics... it will happen... and maybe it will happen closer to what was previously discussed? They'll get it all worked out. I'm pretty satisfied with what we have now... If the models improve too much, lots of folks will need to reinvent themselves. Realllyyy - look at the lead time in topics of impact events. Consistently 5 days +.
  14. Hi! I'm not an analog expert. I don't try to use them. I just go on patterns, and look for the opportunities on whatever light-moderate-major winter event. However, do share with others herein. They may have some helpful comments. Sorry i can't be of more help. Walt
  15. Feb 7-9 has been on my radar for a day or so...continues but no topic for another day or two. I want to see some NAEFS growth. This should be after the warmup of Feb 4-6. Could be an inland runner. At least we have options... probably good to wait and see how 2/1 modeling evolves.
  16. Just too early. If it's a hugger, it's not suppressed. On wind... too early for me to say 50+ but we have it as a possibility. GEFS has a 30% chance gusts 50+ eastern Li late Monday. Will work on the topic header either late today or Thursday as by that time we should have more consensus.
  17. If it's a hugger, it could be a lot of rain. Predominant track is debatable... suppression is better for the coast. What I do think is that half a foot or more is likely wherever the best track of this long duration event is (VA-northeastward). That's why it's good to enjoy these small events that we just had the past 24 hours; no guarantees on the next decent snow. Pattern evolution looks good to me. Probably good to be enthusiastic about a nor'easter but not locked in on the big snow axis. Fingers crossed for whatever the forum wants. I just hope to surpass my very low 2019-20 winter total by Feb 3 here, which was about 20.7". Just need 2.8". Think we can do that pretty easily near I84 but if suppression dominates and shoves the track axis further southeast, then that could be in jeopardy. Just too early. I think WPC has a decent mapping.
  18. Where is here... I can never tell for sure from the member locations that sometimes differ from actual. Thanks and I apologize that I don't recall-- so many members. Thank you again.
  19. Postied overnight basics from WPC. 00z/27 EPS very steady 6+ inland w of I95 DC VA northward to new England (despite the op member), GEFS a little less northwest but fairly steady, GEPS-GGEM and UK op appear suppressed southward and of course the 00z/27 EC op suppressed as well. Plenty of variable solutions on the table. NAEFS is steady on this being a decent snow event for at least a part of the I95-I84 corridors though slightly slower onset (late 31). The graphics are WPC's ensemble confidence of 3+" of snow for the 24 hour periods ending Feb 1,2,3.
  20. Will do a CoCoRAHS summary and eval around 10 or 11A. Should be basically 1-2" with a little zr- or zl- just s of I84 to 2-4" n of I84 with only spotty zl-. Maybe some 5s"? Catskills to extreme n CT High terrain?
  21. Wantage NJ (this part). 1.3" with flurries in progress. 27F Lovely morning here. 27F.
  22. Wantage NJ (this part) 1.0" steady estimated 2-3Mi s-. slowly adding on a bit. 26.1. cooling very slowly from the 11AM high of 28.0F.
  23. Don and others (Bluewave etal) who may look at this predictive data a lot... has the EPS or GEFS been better at LR predictions of the AO, NAO, PNA, EPO lets say at 10 days, and 16 days? I see some differences in the these ensembles...the GEFS overall a little more favorable for winter. Not sure who said winter over? Doesn't look that way to me yet into mid Feb. Maybe it is over, and I don't/didn't realize it??? Thanks, Walt
