Pretty dead on the NYC forum the past day or so... yep, not much to talk about. There is a 2 hour northeastward transitory window of opportunity for the higher terrain of the I84 corridor to see a showery spritz of mPING noticeable ice pellets-flurries, or freezing rain sprinkles, between 8A-2P. That band as this is written 647AM is now trying to grow east -northeastward between I78-I80 in PA-NJ. So far, dry air at 850MB is evaporating whatever is trying to reach the ground. This band of showery very light precipitation should gradually organize a bit more as it passes out of ne PA/se NYS after 1030AM and heads toward ALB-CEF. That's as exciting as i see it on front end wintry events. The Wed morning possibility still exists, but chances are 80% that it won't occur. sighhhh

Following up this Saturday morning nw suburbs! It's Nov 21 and while no big snowstorms are outlooked here through November, it's not necessarily completely devoid of snow. A brief period of ice pellets-flurries or freezing rain is possible for the I-84 high terrain corridor 9A-3P Sunday, especially Poconos and possibly extreme nw NJ/interior se NYS There may be another period of snow I-84 northward Wednesday morning, with less than 1" high terrain accumulation possible (see 00z/21 UKMET). These are exceedingly minor events, if they were to occur but it's something that may briefly spark mPING interest for the wintry weather diehards (me), IF they were to occur. NO guarantee's. This paragraph is based on 00z/21 multi model usage, leaning on the NAM-3K, UKMET, SPC HREF. Have added 06/21 NAM FGEN modeled prediction for ~9A Sunday. Right now that says little or nothing for I84 but if that happens to extend a little further east (red is FGEN) in future modeling-reality, then we're in. Thermal profile for MSV (Monticello NY) suggests ice pellets or freezing rain, BUT, if the fgen lift is stronger then the column cools the warmer dryer layer near 850 MB seen around 15z (10A) and suddenly we have a few minutes of snow. For now, it's a long shot and all I can excited about in the next few days. When you look at the KMSV profile, any precip before 7PM Sunday night certainly can freeze over the higher terrain (sub 32F profile). The question then becomes, is the modeling a touch too cold there in the NYS high terrain? (I also use KMSV for extreme nw NJ near State Route 23 (High Point-Montague and Wantage). 655A/21

Good morning, I did not post a minuscule snow outlook on the main forum since it won't affect NYC but tossed it in the nw suburbs portion where even extreme nw NJ may briefly (hour or two) see some snow or sleet Sunday and Wednesday. Wish it were better but I think of this... as scientifically depressing the outlooks herein for this winter, the sample size can always be expanded with normal seasonal snowfall. Timing-timing-timing of short waves with cold air.

Good Friday morning nw suburbs! It's Nov 20 and while no big snowstorms are outlooked here through November, it's not completely devoid of snow. A brief period of little or no accumulation for the I-84 corridor is "possible" 9A-3P Sunday. There may be another period of snow I-84 northward Wednesday morning, with less than 2" high terrain accumulation possible. These are exceedingly minor events, if they were to occur but it's something that may briefly dress up the landscape, IF they were to occur. NO guarantee's. This paragraph is based on 00z/20 multi model usage, leaning on the NAM-3K, UKMET, SPC SREF plumes and nearby ECMWF hints.

fwiw... past 24 hours rough idea of new snowfall. This part of Wantage NJ Trace both yesterday and this morning.

Trace of snow showers here in Wantage NJ since 730A. mPing has some snow obs.

One note: and this is written not knowing if a TOR survey is being conducted... but warnings are warnings--- whether they verify is another matter. Therefore, what to me is most important on TOR climo, is not the # of warnings but # of occurrences. The warning for me only means big wind is being detected with probable rotation to the surface. I didn't check but I suspect this was an updated warning (TOR) embedded in what previously had been a big lead time SVR. To me the prior SVR would be the critical notifier-headsup... take cover! EF1 (86MPH+ ) or greater is more important to me than the EF0's- from a science standpoint I understand EF0 documentation but from a lead time value added here in the northeast with many fleeting short lived EF0 signatures, the prior SVR was critical. For what it's worth, HSLC environments like yesterday's can produce embedded TOR's and was what I was hinting at in pre-event discussion of breaks in a line etc. I just didn't want to name it... modeling for the TOR I thought was minimal and mentioning TOR puts pressure on forecasters, just via ph calls. I think it gets too much attention unless it's clearly signaled via modeling, radar, debris signatures and most of all ..ground truth.. Again, this is written without knowledge if there was a tornado or not.

Hi. I don't know on both, perhaps others might. Strong PPP falls and some rises behind may have caused the seiche on LErie along with strong westerly gradient. Presume you meant 1.5 ft seiche...not 15 ft tsunami-like impact. Derecho... long lived for sure, and not sure if enough 75 MPH wind gusts? Am sure others may have more info to answer. Here's some info you can do some additional research into. When i think of Derecho...I tend to think spring-summer and many 75-90 MPH gusts enroute. However, I must be corrected if am wrong. Thanks. One of the authors, is the recently passed, excellent SELS-SPC forecaster-teacher = Bob Johns.

Just for the fun of it...take a look back at the Eta Remnant potential thread p2 1148AM Friday post which had the timing of the squall line. RGEM vs NAM3K. Amazing RGEM timing. This was just 8 hours before this damage thread was started Friday evening. I've been liking the RGEM lately...expresses qpf areas nicely, and timing. Might be slightly too robust on qpf amount but overall... a worthy check through the Tropical Tidbits link, or your other favorite resources.

Some early 5 day summary info appended. Includes NYS mesonet and radar-sensor qpf for the entire period. (i in Wantage NJ had only .92 on the edge of the blue area in nw NJ). Added CoCoRAHS around 115PM. Initial topic 1-3" was better than the followup 2-4 iso 6 for our NYC forum. Rainy-drizzly a good part of the daylight hours Wed-Thu-Fri, then final event arrived very late in the day Sunday the 15th.

Good Monday morning all, Here's a quick summary of max gusts in the OKX area, that the NWS reported. Am pretty sure there will have to be an update later today.Havez no idea if a TOR Survey is planned? Seems like 50-65 MPH was common in the more intense bands. Am heartened that the Richardson # and wind fields from the 3K NAM were valuable prevent assessments. This same 3K NAM was 2 hrs too fast with the squalli line on Friday...RGEM superior. Power outages not quite as bad LI/CT as expected. See pix for this morning. The customers out = meters. Most homes have only 1 meter. So, for total people out...safely, twice the # of meters. I'll wrap up the 5 day thread separately around 11A. Thanks for all the reports. LOCATION MAX WIND TIME/DATE COMMENTS GUST OF MPH MEASUREMENT CONNECTICUT ...Fairfield County...

Did not check... but the 70 makes sense... per modeled profile. Am not surprised. Rooftop it is... which can also be tree crown top at 30-40 feet above ground level.

I may not post too much anymore for tonight... i think things are on track. Keep going strong.

Staten Island on official NYS mesonet. 61 MPH now.

Yes we flicker up here, but am thankful no generator power, therefore can contribute on this forum. A glimpse of a well run electric cooperative. Still with quite a few meters out... and why we were flickeking. 10% of our Sussex County Rural Electric Cooperative without power.

My Wantage NJ 47 MPH fits nicely with nw NJ... 62 MPH at Mountain Creek now. Looks potent for central-eastern Li especially --possible 65 MPH +?

Mount Pocono 48 kt at 726P, ~1 hr after sqline passage. That's why we have pre sqline (now), then sqline damage, then possibly a westerly gust within ~an hour after sqline passage for 40kt + winds.

47 MPH at 755 PM at our home at 740'MSL in Wantage NJ. lights flickering.

Power flickering here in Wantage and just had 367 meters go out just n of Sussex NJ.

Quakertown PA 47 kt. Otherwise seemingly a little less than I'd like to have seen in e PA. Reports still coming in.

57 MPH at Mountain Creek ski area in nw NJ. Map attached. a number of 50 MPH on LI now via mesonet and Bluewave post.
