  1. First 90 of the season at JFK. https://forecast.weather.gov/product.php?site=NWS&issuedby=JFK&product=CLI&format=CI&version=1&glossary=1&highlight=off The actual temperature in the sun at Central Park is probably close to EWR and LGA. But the deep shade where the sensor is runs a few degrees cooler than open areas like the Great Lawn. I am willing to bet the open areas of Central Park probably came close to 50 days reaching 90 in 2010.
  2. Impressive stretch of early July heat on the 12z Euro today.
  3. First 95 of the season at Newark with warm downslope flow. http://wxweb.meteostar.com/meteogram/link.shtml?choice=KEWR
  4. Maybe close to 60 days if we get a dry enough pattern with the mean ridge position nearby.

  6. Today looks like an overperforming downslope day. HRRR has low 90s for areas that get into the NNW flow.
  7. Pretty extreme rainfall rates in Harrison. Looks like they picked up 1.46 in just 14 minutes. Total of 2.79 in a little over an hour. https://mesowest.utah.edu HSNN4 Harrison 13:16 66.0 64.2 64.9 94 0.0 3.0 29.84 29.86 2.79 2.79 OK 13:02 65.0 62.9 63.7 93 0.0 0.0 29.85 29.87 2.79 2.79 OK 12:47 66.0 63.0 64.1 90 0.0 1.0 29.86 29.88 2.73 2.73 OK 12:31 67.0 63.0 64.4 87 0.0 5.0 29.86 29.88 1.87 1.87 OK 12:17 73.0 64.6 67.3 75 5.0 10.0 N 29.87 29.89 0.41 0.41 OK 12:03 76.0 66.7 69.6 73 0.0 3.0 29.83 29.85 0.00 0.00
  8. Looks like another warmer than average July coming up. Models have a 590+DM heat dome building over the Plains and Midwest. So that will probably be our first extended stretch of widespread 90s across the region.
  9. It will be interesting to see if the Euro is correct about the slower backdoor cold front on Friday. The model actually has upper 90s to our south. We were discussing the unusual WAA from SE Canada ahead of the front.
  10. Yes. It was the first 71 degree or warmer June at JFK not to reach 90 degrees.
  11. We’ll need some help from convection later for several stations to avoid their driest June since 2010.

  12. First June that Newark averaged 74 degrees or warmer and didn’t have a monthly maximum temperature above 93 degrees. Newark is currently at the 10th warmest June on record. But the monthly maximum of 93 degrees is the coolest for all 74 degree or warmer years.

  13. Many people in this part of the country have never experienced hail before. So they just associate anything frozen falling from the sky with winter. Plus they don’t follow the weather as closely as we do.
  14. First June since 2009 with no 90 degree days at JFK. The 89 today was the high for the month. Very few warm offshore flow days with the onshore flow dominating.

  15. Warmest June at EWR and LGA since 2010 and 2011. But the monthly maximum temperatures were much lower. Fits with the highest June maximum temperatures going to our north.

  16. A backdoor warm front on the 3rd followed by a backdoor cold front on the 4th.
  17. My guess is that the climate has become too wet here to allow for another 1960s style drought. That was something like a 500 year drought based on the tree ring study. Ever since 2003, our dry patterns end before we get to any serious water restrictions. https://blogs.ei.columbia.edu/2012/09/06/epic-wetness-in-the-greater-new-york-city-region-and-what-broadleaf-trees-have-to-say-about-it/
  18. First storm of the day firing on the sea breeze front in Nassau.
  19. Based on the OKX 12z sounding, storms should remain strong to severe right down to Long Island.
  20. While the June high temperature departures have been well above normal at EWR and LGA, there hasn’t been an excessive number of 90 degree days for June. The +2.5 high temperature departure at Newark at 83.6 is the 10th warmest. The +3.5 at LGA and 83.6 is 5th warmest. But there has been a record number of 88 degree days at LGA and 2nd place so for at Newark. LGA also recorded the 3rd highest number of 89 degree days for June.

  21. The NAM convection placement has been off recently. Too bad they had to suspend the HRRR v4 and delay implementation. Those 24 to 36 hr convection forecasts seemed to be pretty good when the forecasts were on COD weather. Would be nice if they could develop a new CAM run off the ECMWF.
  22. Heavy downpour here in SW Suffolk. Pleasantly surprised to see the echoes intensify once east of NYC. Winds also picked up with gusts to 35 mph at the Wantagh mesonet.
