RECORD EVENT REPORT NATIONAL WEATHER SERVICE GRAY ME 741 AM EDT TUE JUL 28 2020 ...RECORD WARM LOW TEMPERATURE SET AT PORTLAND ME... THE LOW TEMPERATURE AT PORTLAND, ME YESTERDAY, JULY 27, WAS A VERY WARM 78 DEGREES. THIS BREAKS THE RECORD FOR WARMEST LOW TEMPERATURE ON THIS DAY. THE PRIOR RECORD WAS 69 DEGREES SET IN 1979 AND AGAIN IN 1989. IN ADDITION THE LOW TEMPERATURE OF 78 DEGREES ALSO SETS A NEW ALL- TIME RECORD FOR WARMEST LOW TEMPERATURE FOR THE PORTLAND JETPORT. THE PRIOR RECORD WAS 76 DEGREES SET ON JULY 22, 2011 AND AGAIN ON JULY 21, 2019.

That would be the highest in July since 2000 when the xmACIS2 record started. Looks like July 1999 had a 82° minimum. There was also another in August 2006. We'll have to see if that can hold through any convection later. https://www.wunderground.com/history/monthly/us/ny/farmingdale/KFRG/date/1999-7 Time Series Summary for FARMINGDALE REPUBLIC AP, NY - Month of Jul Click column heading to sort ascending, click again to sort descending.

Yeah, warm air and high dew points. This may be the first time that a Long Island station had more 75° minimums than LGA in July.

You would really have to search for that. I just remember the old NOAA Weather Radio hourly updates with the marine reports. https://www.ndbc.noaa.gov/station_page.php?station=44025

I believe the 81° at the buoy south of Fire Island is right at the record. I can remember many years growing up when the warmest for the whole season would be around 75°. 20 S Fire Island 2150 81

Another day with the SSTs at the buoys around 80°. Even the Boston buoy is in the mid 70s.

Record highs at ISP and BDR

All day westerly flow heat events have been few and far between on LI since the super El Niño in 2015-2016.We would get one after another from 2010-2013. Onshore flow and record dew points have become the new normal.

Made it to 91 before the sea breeze arrived. 89° now with a SW wind and the dew point rising to 69°.

A top 5 warmest summer so far at many stations across the region. Numerous temperature departures in the +3 to +4 range since June 1st. Just shows how cooler patterns like April and May don’t have lasting power anymore.

LGA has been tracking pretty close to Astoria which is also in Northern Queens. https://mesowest.utah.edu/cgi-bin/droman/meso_base_dyn.cgi?stn=D3216&unit=0&timetype=LOCAL Weather Conditions for D3216 DW3216 Astoria Current Time: 07/26/2020 16:52 EDT Most Recent Weather Conditions at: 07/26/2020 16:45 EDT Graphical Links 16:45 Max Since 0:00 (EDT) Min Since 0:00 (EDT) 24 Hour Maximum 24 Hour Minimum Temperature 94.0° F 95.0 at 15:25 78.0 at 7:12 95.0 at 15:25 78.0 at 7:12

LGA and EWR switched places following the super El Niño in 2016. EWR was the local hotspot from 2010 to 2015. But LGA took the lead in recent years.

This may be a first for an extended period that I can remember also. The upwelling from Fay only lasted 3 days.

I haven’t been able to find any 80° months on Long Island south of the Long Island Expressway. Even JFK has only had 1 month to average 80° in July 2010. Maybe there have been some stations north of the LIE on LI that did it.

We did notice the LGA summer temperature departures pick up in 2016 relative to EWR and JFK. It’s interesting that there was a similar increase at BDR. Both stations have been tracking pretty closely since the super El Niño in 2016. They are our closest stations to the Long Island Sound. Maybe a result of the warmer SSTs on the sound and record dew point regime since the super El Niño. Could also be a local response to general circulation and temperature changes since then.

It also looks like the warmer SSTs are helping FRG go for the July 90° day record. The only other year since the records began in 2000 to reach 10 days was 2010. That had much more westerly flow compared to all the onshore flow this July.
