    Rapid intensification has become the new normal in recent years with the steadily warming SSTs.
  2. bluewave
    Nice improvements from the 0z Euro and GEM getting 2.00” to Long Island now.
  3. bluewave
    Euro and GEM continuing with the sharp cutoff to the northern extent of Ian’s moisture. Blocking still looks pretty strong on both models. We’ll have to refine forecast after later runs to see exactly how far north the rains make it.

    Even though temperatures have cooled off over the last week, areas from EWR to LGA continue to average near 70° for the month. This has been a common occurrence since 2010. But at least we will step down from all the record warmth in recent months. So less warm is the new cool as the late month cooldown prevented another top 10 warmest month.

    All the guidance has a sharp cutoff to Ian’s rainfall just to our south as blocking Canadian high pressure dominates.
  6. bluewave
    The record blocking will result in a cooler pattern into next weekend across the area. So Ian is expected to stall out near the Gulf Coast of Florida. This is a continuation of needing record blocking just to get cooler than average temperatures around here.
  7. bluewave
    The OP Euro is finally coming into line with the EPS, GEM, and GFS on the slower track of Ian. The impressive Fiona wave break is setting up a strong blocking pattern to the north. So we’ll have to see how much moisture can make into our region after the system weakens. New run Old run

    The first 45° of the season came in a bit earlier than the recent average since 2010 at Islip. https://www.weather.gov/wrh/timeseries?site=kisp 45 First/Last Summary for ISLIP-LI MACARTHUR AP, NY Each section contains date and year of occurrence, value on that date.

    Yeah, Sandy would have been stronger had it occurred a month earlier with a record warm pool like this.
  10. bluewave
    Fiona will probably be the strongest storm to hit Nova Scotia.

    Newark has a shot at 40s tomorrow am which would be early by recent standards.

    Most of the guidance like the EPS and GEM have a slower track north with Hermine. So the OP Euro seems to be on its own at 0z The other models have Hermine missing the first trough and stalling out near Florida. The GEM may be the middle ground with Herimine finally getting lifted north with the second trough next weekend. Hopefully, we can eventually get some rain from this.
  13. bluewave
    The OP Euro is a faster outlier with the track of the tropical system next week. Several EPS members stall the system near the Southeast as blocking builds to the north. So the strength of the blocking will determine if we can get a decent rain or not.
  14. bluewave
    Impressive Fiona wave break will set up an strong blocking pattern for the rest of the month. First lows near 50° in NYC by Saturday. Then the next tropical system gets stuck underneath strong Canadian high pressure to the north. So that my be our best shot at soaking rains around the area depending on the exact track.
  15. bluewave
    Looks like Canadian high pressure will dominate later in the month. So plenty of easterly flow in the forecast. Any tropical moisture coming underneath will help us out.
  16. bluewave
    The Fiona wave break will produce a record 590dm ridge south of Greenland. So Friday into Saturday looks like the first actual fall weather of the season. Lows near 50° in NYC and highs not getting out of the 60s for a day or two. We continue to need record blocking just to get some cooler weather around here.
  17. bluewave
    That’s a given but the GEM and Euro were just as hot. The blocking verified stronger. So we get a +10 day instead of +15 to +20. That’s what passes for cooler in our warming climate. Almanac for NEWARK LIBERTY INTL AP, NJ September 19, 2022 Daily Data Observed Normal Record Highest Record Lowest Max Temperature M 77 93 in 1983 62 in 1987 Min Temperature M 60 70 in 2016 44 in 1959
  18. bluewave
    It looks like the heat may peak today in the upper 80s instead of the mid 90s which was forecast last week. So I guess this counts as making slow progress toward fall. NYC could see the first lower 50s of the season by next weekend as a stronger blocking pattern sets up. New run for today Old run much warmer Cool down for later in week
  19. bluewave
    The AWB produces a near record 500mb height anomaly just south of Greenland. So the -NAO could have some lasting power. It could be another case of needing record blocking to get some cooler to closer to normal temperatures around here.
  20. bluewave
    Classic recurving hurricane hurricane track and cool down that pumps the -NAO later in the week.
  21. bluewave
    Fiona would be a nice cold front for us on the 0z Euro.
  22. bluewave
    Another factor is how the record Bering Sea storm for September will influence the 500 mb pattern.
  23. bluewave
    First refreshing airmass since last spring across the area. We needed stronger enough blocking to pull it off. The alignment of the blocking and trough to the north will eventually influence the track of Fiona.
  24. bluewave
    Only .16 since Monday at the Wantagh mesonet. Precipitation 6 hours: 0.16″ 1 day: 0.16″
  25. bluewave
    Similar finish to last year with near a 5 million sq km September average extent.
