  1. It won’t open. But the most recent summer photos in 2013 had the thermometer in the deep shade. Winter isn’t a good time for photos since the strongest cooling effect occurs after spring leaf out. The proximity of the vegetation to the thermometer violates the sitting rules for official temperature measurements.
  2. While it may seem that way, Newark has actually had less summer warming than the rest of the forum since 1981.
  3. It all depends on what the dominant summer pattern is. This year the regime is favoring NE NJ for the most heat. Last summer it was east of the Hudson with LGA and Hartford recording more 90° days. Also remember that Newark just ended its longest no 100° day streak this summer. June had the first 100° day since 2013. But LGA and New England had several 100° readings in recent years. 2020 days reaching 90° Newark…..31 LGA………..34 Hartford….39
  4. Northeast NJ has been able to avoid the cooler onshore influence that has affected the rest of the area. Caldwell is +1.2 and Newark is lower at +0.5. Follows the theme of this being a hotter summer west of the Hudson away from the cooling seabreezes.
  5. There are two main differences between this summer and last for extent. May 2020 featured record preconditioning of the ice for the second lowest extent last September. Last summer also had very strong high pressure. This June and July had the second lowest Arctic pressure on record behind 1989. While the tweet below was focused on the record lack of sunny days near Alaska, you can see how the extreme low pressure pattern kept the Arctic very cloudy.
  6. This is only the 8th year that Newark reached 30 days of 90° following a 40 inch snowfall season. This feat only occurred three times up to 1994. But a record breaking five years since 2005. So we are getting an unusual combination of stronger winter blocking followed by summer heat.

  7. The highest dew points went to our north today.
  8. High of 97° at EWR and 95° at LGA through 2pm.
  9. Temperatures are off to the races with Newark jumping from 85° to 90° in one hour. 12 Aug 10:51 am 90 73 58 SW 9 10.00 FEW250 29.99 1016.3 30.01 12 Aug 9:51 am 85 72 65 W 6 10.00 CLR 29.99 1016.3 30.01
  10. The record at JFK is 115 and 129 at Newark.
  11. The NWS really needs to address the situation with the trees blocking the sensor. They didn’t seem to take it into account with the official forecast for today. Notice how the forecast did very well for all the other stations. But it was 4° too high for NYC.
  12. Miami dew points across the region. MIAMI PTSUNNY 91 75 59 E10G22 30.09F HX 101 Poughkeepsie MOSUNNY 90 76 63 S7 29.94 HX 101 Newark/Liberty MOSUNNY 93 75 55 SW14 29.96 HX 104 Somerville MOSUNNY 91 77 63 VRB3 29.96 HX 104 Kennedy Intl MOSUNNY 83 75 77 S10 30.00 HX 90
  13. 84° is the highest on record at JFK and EWR. The JFK record was set in 2016 and Newark in 1995. While the Sussex County records only go back to 2000, your record is 79°set in 2016. You can see how many hourly records there have been at our stations in the last 6 years.
  14. Newark just jumped up to 91° Making it to 30 days reaching 90° again.

  15. It’s a tropical airmass with PWATS and dew points near the higher end of the range for this time of year,
  16. 2019 to 2021 has been the most active through August 10th on record for NJ severe thunderstorm and tornado warnings. https://mesonet.agron.iastate.edu/plotting/auto/?_wait=no&q=44&plot=line&opt=state&station=DMX&state=NJ&limit=yes&c=svrtor&phenomena=TO&significance=W&syear=1986&eyear=2021&dpi=100&_fmt=png
  17. The max 850 mb temperatures from Thursday into Friday around +22c should approach the August monthly highs since 1979. So the surface highs will come down to the timing of the daily convection potential. Best chances to reach 100° will probably be the usual NE NJ warm spots around Newark. Maybe even around LGA or other warm parts of Queens.
  18. Good model agreement on 850 mb temperatures in the 20-22C range. So this should allow the warm spots to reach 100° or higher. It would be the first June and August 100° or warmer at Newark since 1993 and 1953.

  19. The -AO/+PNA fans are hoping that the Euro seasonal isn’t smoking something.
  20. We are witnessing the compounding effects of multiple issues. The warming climate is drying out the West to record levels providing more fuel for the fires. So the fires grew to record levels whether the spark is caused by human activities or nature. Poor land management has also contributed to the build up of fuels. People have moved into very high risk areas. It’s very expensive to bury power lines. I am not sure how people will afford steeply rising electric rates to pay these costs. Property insurance is also getting very high in those areas. So people are getting priced out of the market. Many are getting tired of all these fires and costs and moving to other parts of the country. So by just letting climate change run, we are creating a regressive climate damage tax which falls hardest on people with lower incomes.
  21. Figures that Christmas had warmer weather relative to the means than the Memorial day and a July 4th weekends.
  22. 10 out of the last 11 weekends since Memorial Day had at least a T of rain. The extended Memorial Day and July 4th weekends were unusually cool and damp. So it will be interesting to see if maybe we get a stalled front or tropical system for Labor Day weekend. Not sure if we ever had all 3 big extended holiday summer weekends with significant rain before.
  23. It’s the land ice that’s at risk in Antarctica from warmer SST’s below the surface. But the tipping point will probably come by around 2060. That’s when we are on track to pass +2c of warming. The big unknown at this point is whether the WAIS will break up over a few centuries or several decades.
  24. We would probably have ocean temperatures in the 80s with a marine heatwave like Japan is having. So we’ll see if the East Coast ever gets one as severe in coming years.
