When I said worst summer ever it wasn't an exaggeration. The combination of high temps and humidity is worse than any start to summer I can remember 

there were a few people saying it would be a cool summer....:lol:

oh please no it isnt...for starters it took forever to actually get a 90 degree this year....also 2years ago we were searing with no rain and days and days of upper 90s and sometimes 100

It's literally the hottest summer on record at Newark and New York City.

*The 1993 and 1994 readings are erroneous. The HO-83 hygrothermometer in use at the time had a significant warm bias, particularly on sunny days with light winds. The location near the tarmac at Newark probably worsened the problem, as the fan was drawing in superheated air. On average, the ASOS installation was 1.2F cooler for daytime maximum temperatures, and 1.0F cooler for minimum temperatures. But at Newark, the bias may have been more substantial.

*The 1966 readings from Central Park are probably not directly comparable to readings today.

Sources:

climo_rpt_96_2.pdf (colostate.edu) - Study of 79 first-order climate sites between 1994 & 1995 found an average annual max temperature bias of +1.16F, and an average annual low temperature bias of +0.95F from the HO-83 relative to the ASOS installation. 

Comparison of ASOS and HO-83 temperatures at Lincoln, Nebraska from November 1991 through October 1992 (noaa.gov) - 12-month study from Lincoln, Nebraska study 1991-92. ASOS was from 1.4 to 2.6F cooler for maximum temperatures every month, and from 0.7 to 2.5F cooler for minimum temperatures.

An Investigation of Temperature Discontinuities Introduced by the Installation of the HO-83 Thermometer in: Journal of Climate Volume 8 Issue 5 (1995) (ametsoc.org) - Another study, somewhat smaller estimate of 0.6C bias - actually suggests less bias in summer, but not sure that is correct.

The HO-83 Hygro- thermometer « Climate Audit - cites some more sources, particularly about Tuscon and how the NWS could not confirm a global warming signal in the deadly Chicago heat wave of 1995 because the readings were likely inflated by instrument bias

Like I said, people "feel" it's cooler because they are so acclimated to the heat. I told the Harrisburg crew they should be comparing their summertime temperatures to Richmond, Virginia. It's one of the hottest summers on record at Harrisburg, but compared to historical, 20th century summers in Richmond, it's still a very hot summer just not among the record hottest. I think the New York City crew should do the same. 2024 is among the hottest on record at NYC and EWR, but if you compare NYC to 20th century Richmond and EWR to 20th century RDU then it's still well above the typical summer in those locations during that era, but not among the hottest on record. The DC crew can use Tallahassee or Savannah, Georgia.

Can't wait for someone to "ackshually" me. The 1966 reading is bogus - the park was 1.2F warmer than the EWR tarmac? GTFO. Yes, it's cooler than 2010, but not by a margin that anyone can discern. And, of course, the 1994 readings are absolute garbage measured by garbage equipment that are not comparable to readings taken before or after that era.

I see GFS on the 12z run now is giving us very little rain for late week. Not that I buy that. It does appear that most of the rain is going to miss us to the west on Wednesday, but there should be plenty of heavy downpours around Thursday and Friday. Especially Friday ... that looks like our best chance.

It has rain Saturday but splits the area with the heaviest amounts

Nam and euro have very little thru Thursday. Cmc still very wet

So it's the hottest summer on record, even though it's only July 8th?  Get back to me in two months.

It's a hot start to summer, but let the rest play out.
