  1. NYC heading for a 7" month of October with over 1.95" for this storm as of 7A. Seldom if ever see 4 onset months of 7+... not there yet but I think NYC heading for near 5 on this one. Added some rainfall totals... so far via CoCoRaHs and NYS mesonet. Also gusts 35-35 KT now north shore of LI as sfc low near Sandy Hook.
  2. I'm leaving the thread title as is.... however, I think our forum will receive a general 1-3" rain later Friday-Saturday. Models have quite a southern sweep of the trough and while it weakens northeastward through us during the weekend, too late. Inflow of PW near 1.75" has occurred and I see a 6-12 hour rain of 1-3" with leftover weekend showers topping a few spots off with possible 4" totals. Depending on what we have by sunrise Wednesday, I may include isolated weekly max total of around 11-12" Still a little early. Winds not as strong but soft ground still remains. This one looks to me to be a potential flood potential enhancer (or delayed recessions etc) for NJ/se NYS. 637A/26.
  3. Weatherflow Tempest is doing just fine... #'s comparable to surrounding weather underground and will review with CoCoRaHs later this morning. On-line till about 11 and then done til 5P or later. Wantage NJ so far as of 610AM 2.51". When you're in the heart of it, sometimes you like to raise amounts. Holding firm. I think much of NNJ NYC Metro and se NYS, ne PA will be around 5-6" with the bulk done by 2PM (less e LI CT). Isolated 8" by the time this is done daybreak Wednesday, somewhere with 40 miles of the NJ/NYS border into extreme ne PA border with NYS. I just need to think of the entire forum. Will rereview title in a few minutes. The wind is another story. I could see a pulse of 35-40kt gusts 10A-2P, but the real deal back breaker is the well defined southwest moving 70-85kt 850 MB jet core rotating back toward us with the storm center. Wind gusts for a 2-4 hour period of 50+ MPH gusts for LI, CT s of I84 tonight, mainly 10P-7A and that will probably result in quite a few power outages with potential for 70 MPH gusts e LI. I relied on the HRRR, HRRRX, and the Richardson # with the 3KNAM--- i t looks very rough s CT e LI. The only hold back by mets may the somewhat less than ideal sounding (not adiabatic), but turbulent turnover may win out. Be prepared for the power outages late tonight which if occur will mean power out for quite a while, and if they don't occur, it's an area for modeling improvement (or my faulty terpretation). Will update the overall thread for Friday-Saturday by 7AM. Added the HRRRX for axis of best rainfall.
  4. 0ver 3/4" in less than 1 hr Wantage. My rain data is very close to digital output. i see over 2" in parts of ne NJ now. This is going to be bad news for parts of NNJ/se NYS/NYC/maybe ne PA too. After all the rain next 18 hours we send a bunch of wind southwest thru CT/LI to add power outages.
  5. At this point, I see a sizable event, slower than currently modeled but my interest is what is going on now. Just pounded 3/4" in less than hr here and i see 2+ inches to my east where a flood warning in effect. I think we've got a big problem ahead for parts of our forum. Wind rain-power. It's been underplayed too much.
  6. Wont change title numb ens despite being close to that for just the first storm. I think I want to see what we have on the ground by 8P Tue before I 2" to the weekly total. I think we have our hands pretty full with Tuesday-Tuesday night.
  7. Rainfall with the warm front was generally 1/2" extreme north to nil extreme south. Have adjusted title rainfall up a touch to 2-5", iso 8" but that's it for me at this time. Wind I expect as previously noted. Best chance for damaging wind Tue night when the storm center and associated 70kt EPS ensembled jet sweep southwest for a while. 60 kt G seems reasonable for extreme e LI Tue night...the strongest out there.
  8. Davis is the standard... you have one of the best. I just didn't want to take that extra cash away from family. Also, I don 't like paying yearly subscription to share data. However, Davis is I think one of the best.
  9. I'll trust the rain and compare to nearby stations and cocorahs. Think I'll know more at 6A. Linquenda Dr. Beautiful up here - very very very fortunate. I do not want to be disappointed but facts are facts so, should know more by Sat night.
  10. Hi... will update OBS thread TITLE amounts, maybe around 8P as we get going. One thing am pretty sure of... we get big wind and power outages CT/LI and am staying with the near 70MPH gusts. More when I get a new handle on everything after a day of work, and installing (w Nick Stefano and excellent support from Weatherflow help desk) new weather station. Hopefully it does well.
  11. Completing the circle and closing (hopefully) my weather station change. Nick Stefano and Tempest Weather just gave me be their time and necessary guidance-assistance in setting up my new tempest weather station. I feel whole again after being without rain data for 3 weeks. I hope to produce some nice graphics for our group, once we get some data an'd it looks accurate. Tuesday should be a nice test. So I went with WeatherFlow because they are a very good company, they work with the NWS with instrumentation, which is used by the local offices and NHC. So I hope this works out well.
  12. Loaded is probably one of the best set of short term guidance we have. Note the 24 hour amounts ending 8PM Tue (general 2+) from the SPC HREF, and the MAX potential of 7-9". WPC risks of flooding seem a little low and conservatively too far east Tuesday. Marginal risk early Tue AM and then slight risk during the day. There should be some flood problems. Am pretty sure we'll see 40-50MPH gusts ridges of nw NJ/se NYS while the coast should see gusts 50 MPH except near 70 MPH e LI...most of this during the day Tuesday, possibly ly lingering into Tue eve. Looks like a little less wind when you get down to the s of I78 but stay tuned for updates. Difficult to believe we'll escape power outages, with most widespread seeming to focus southern C... LI. Isolated or scattered embedded thunder appears likely tonight and Tuesday. Result is a high impact event , at times, for travel Tuesday in the NYC subforum.
  13. Topic title amounts increased (conservatively I hope) this Sunday evening and have split out the OBS thread for the first storm (tonight-8A Wed). Lots of good modeling documentation-imagery has been added previously to this thread. Keep it going. I can't add much more with any confidence til 6A Monday. I'm still not sure where the worst of this will be, but if it were winter, this storm would be getting much more press with a massive snow storm axised 90 or more miles north of the 850 Low.
  14. This first event is slated mainly for Monday night-early Tuesday night but with a pulse of showers, some heavy occurring overnight Sunday night and potential for bands of high wind and or heavy rain remaining in the NYC subforum into early Wednesday, depending on the departure of the eventual nor'easter. Max gust for e LI may get close to 70 MPH with wind damage 'potential' of 50 MPH gusts s of I84 in CT into far se NYS through ne NJ. Fully leaved tree branches with potential for sodden ground uproots Tuesday due to heavy rainfall and the gusts should result in pockets of power outages from simply broken branches. If it looks extensive, we will update the topic title. Max rainfall seems to be targeting CT/se NYS/NYC metro-ne NJ but proximity of max inflow-moisture transport still showing modeling variability for the primary target. In any case... it appears likely that along and north of I78 there will be periodic showers overnight with new rainfall by sunrise ranging from a few hundredths to possibly 1". After a break Monday, bands of heavy showers should be developing north and northwest into the area Monday evening and slow their northwest to west progress Tuesday before turning southward later Tuesday night. By 8AM Wed, isolated 6" rains may have occurred with a general 1.5-3" in the subforum. FF potential while initially limited by recent dryness, the rainfall rates and amounts in banding will eventually determine where any FF potential will be realized-it's just too early to determine, as of this 720PM Sunday writing. Please follow all future NWS warnings/statements. Let's see what the OBS herein tell us about the modeling by Tuesday night. Edited title rainfall up from 1.5-4 iso 6, to 2-5, iso 8. Edited title at 1025A/26 to like 40-60KT gust focused on CT-LI.
  15. By Saturday yes, and probably parts of CT, e Li on various elements. Will start an OBS thread for the first one with more defined expectations, probably at 6PM today.
  16. I may adjust the title a little bit at 4PM, pending 12z/24 guidances. The adjustments would be to add inches to the title and hit the wind damage as potentially widespread by Halloween but again, nothing to overcommit quite this far in advance. These storms may seriously impact air travel along the east coast Tue-Wed morning and again Friday-Saturday. Also possible residual effects in ATL Friday??
  17. Early morning WPC outlooks: Heaviest rain eastern part of the subforum on storm one. Two storm totals from WPC, general 5" for most of the NYC subforum and spotty 7" MA.
  18. So, this is a new tool to use for many on here... click the 0 hour on IWT or IVT and then use your arrow keys to slide through the model guidance. This is GFS and NAM only op runs. However, you see something of what Blue wave wrote. Also, imo, the second event late this coming week may have some of Hurricane Rick RH in it. Take a look at the eastern side of the storm. https://cw3e.ucsd.edu/ivt_iwv_namerica/
  19. WPC 7 day qpf. Everything inside the red contour is 5". I would have to think media is going to have to start arousing concern. It is not everyday that WPC puts out 5 and 6" weekly contours in our area. I will add FF to the tag now. I am aware that river flooding might be the more common result of these events later this week, but I have to think FF will occur when intense rains are continuous for 3-6hours at 1"/hr rates. FF added at about 430P/23.
  20. We are seeing some very large #'s this week for the NYC subforum. Also some of the modeling doesn't agree in the GFS/NAM/EC modeling which i do believe...it's where. 12z/23 GFS as I'm sure you saw has 8" for NYC this coming week. I would necessarily focus in on NYC itself but somewhere in our forum, there seems to be a pretty good chance of spot 7-9" amounts by Halloween. Attached is the new midday NWS WPC ensembled approach to next Fri-Sat. We'll see what happens, if this occurs as predicted but the potential exists for somewhere along and N of I80 up into central NYS-central New England. Those reds are about 3-4.5". Will append the new 7 day totals at about 4P as my time allows and available from WPC. Modeling also is suggesting two separate storm occurrences of 850MB 70 knot se inflow. Again we/I don't know anything for sure, but am confident some validated warning events are coming next week. Where, am unsure... there can be important shifts but the focus continues here, somewhere in our area.
  21. Courtesy Weather.US as are many of the graphics I post. Look at these 06z/ECMWF OP graphics. I don't think it's too early to lean hard on EC ideas. It's just a matter of severity and location that it begins. That's 5" of rain e LI and 5+ Ct River Valley. Possibly too much or mis located. Part of this has the 06z/23 EC raising PW to 2" near LI.
  22. Bring the umbrella... follow the HRRR for today. Forecasts and outlooks look a little weak this weekend through next week with little heads up of the coming and already in progress dismal weather. Had drizzle/sprinkles last evening here in nw NJ per prior Mping reports. (EC did the best with its new convective scheme, especially the midnight ish showers that occurred here early Friday morning). It's raining now (650A) here in Wantage and more to come today... a rather chilly and occasionally wet day here in far nw NJ, probably closer to the city too. Tomorrow's forecasts seem too optimistic. This all plays into cutting grass and outdoor chores putting away summer stuff. Probably off line most of the morning, Walt
  23. Good Saturday morning everyone, Prepare for adverse weather, possible power outages and possible flood related problems, especially north of I80 next week. The first of the real deal rainfall probably begins Sunday evening-night with evolution of a nor'easter by late Tuesday, followed by a second large scale event though possibly of a differing more inside runner flavor, next Friday-Saturday. Details tbd but here are some graphics to ponder. I'll probably add FF to the tags late Sunday or Monday pending further model confirmation, and SVR will be reserved for last add but it's on the table. WPC has a minimum of 3" forecast for I80 north next week. Graphics below: This mornings D3 SVR outlook for Monday, The EC EPS 500MB pattern 00z/Wed (tue eve), the EC EPS sfc pattern for the same time, and then the GEFS as well at the same time, and finally a rather impressive EC EPS rainfall forecast for just our area...EPS have 5" in central MA (more to the east not seen here) and general 1-3" in our area.
