    good call NJWX....about to upgrade to MDT almost exactly where you have it.

    last few runs of the HRRR showing 60-80KT just above the surface with the line coming thru NYC. makes sense given where convection is developing now for a bow/qlcs to take direct aim. i do think there will be a few tornadoes, but as SPC says the most favored is along the boundary in the northern part of where you've circled, just N of NJ.

    May 2018 Discussions & Observations Thread

    the perfect day at jacob riis. hot sun, cooling breeze.
  4. 18z GFS caught on to the WAA signal tomorrow morning. HRGEM, RGEM, Deep Thunder and RPM have all consistently painted 1-2” for the city. HRRRx looks primed too. Nice lapse rates advect in early with the low level warming on a 50kt LLJ so there should at least be heavy rainers and a few embedded thunderstorms.
  5. ~65KT showing up at 1000' and 75KT at 3000-5000' on local radars. horrible day to be flying due to all the shear. airports and the airspace are a mess. there are a lot of mesoscale circulations in the, for lack of a better term, tropical feeder bands associated with the warm conveyor. very cool things happening meteorologically today.
  6. it's been absolutely stellar the past couple days. nailed all the nuances of convection in florida and the southeast yesterday.

    There are considerable timing differences in the models still...anywhere from Friday night to Saturday night. Hopefully we can clear that up a bit in the next 24h.

    April 2nd Snow Wave

    I'm at work in LIC. 4.5" in the past 2 hours here.

    April 2nd Snow Wave

    The 12Z HREF mean seems to be a nice compromise for the location of potential banding - it still may be a little noisy given the 24h lead time, but a narrow stripe of ~6" seems a good possibility somewhere through the city. A 2-3 hour period of intense frontogenesis collocated through prime snow growth AND decent mid-level lapse rates should result in brief heavy snow rates of 1-2"/hr in narrow, banded snow. It will obviously melt quickly, but I do think the early morning hours could be a mess given the signal for heavy snow.

    one of those bands parked it between JFK and LGA - nearly impossible to predict that ish more than ~8 hours out!

    Ended up with 13" in Bed-Stuy. I measured ~20 times in Long Meadow at Prospect and had an average right at 12". I got there around 7:30 and the woods were pristine. As soon as the sun popped through, large clumps began raining down. that snowman was over 7' tall and slightly horrifying.

    heading out to measure and take pics over at prospect. ref: @Snow88's 500mb closing off - the 200 image WV loop from COD is a thing of beauty (link is high bandwidth). you can see that jet streak and dry punch @NJwx85 and i were talking about rounding the bend - which is when the dynamics took off later in the day. that's an impressive squall line out over the middle of the atlantic this morning, as well!

    the 00Z OKX sounding says a lot. amazing lapse rates thru the snow growth zone (~600mb) and even some weak CAPE.
