90's return later in the week as the WAR builds in and 850's surge to around +18C. Since we don't have a tropical system like Cindy in the mix, perhaps we'll get enough sun to make another run on 95 or greater. But if clouds and convection get in the way, then low 90's may do it. We''ll see...

Looks like there is a good chance of storms beginning Friday (possibly Thursday night) and lasting through the weekend and possibly beyond.

Yeah, we look to continue the theme of most weekends since mid-April featuring at least some measurable rainfall.

The highest average temperature at LGA is between July 13-28. But the record highest temperature for each of the local stations is between 7/3 and 7/22.

EWR....7-22-11...108....NYC....7-9-36...106....LGA....7-3-66....107....JFK....7-3-66...104...BDR...7-22-11....103...ISP....7-3-66...104

Newark New Jersey June average temperature...June average temperature is 73.0...I listed the ten year averages...the coolest is 1982 at 67.9...hottest is 77.8 in 1994...June could be close to average at Newark also...

1991-00.....73.40

2001-10.....72.83

average.....73.02

The current +0.8 at Newark is in line with June having the least top 10 warmth of the summer during the 2010's.

Newark top 10 warmest months on record during the 2010's:

Jun...2010...#2....2011....#10

Jul....2011...#1....2010....#3....2013...#5....2012...#6.....2016....#10

it's not really plus 0.8...it's closer to plus 0.3...noaa has 72.4 as the June mean...

what errors?...

The NCDC sets the 30 year average after they correct for any bad data in the raw numbers. That's why the 30 year means might not be an exact average of the 30 years of raw numbers.

don't they correct the monthly average as well?...

This paper describes how they do it.

https://www1.ncdc.noaa.gov/pub/data/normals/1981-2010/documentation/temperature-methodology.pdf

This report describes the methodology used to compute daily, monthly, seasonal, and annual normals for numerous temperature-related variables at about 7,500 weather stations for the 1981-2010 Normals period. A climate normal is typically defined as a 30-year average of an atmospheric quantity, such as maximum temperature. However, advanced statistical techniques are used to account for missing data values, inhomogeneities, station moves, etc. and therefore the normals presented here are much more than 30-year averages. This report offers a preliminary description of all procedures used to compute the new normals for temperature-related variables. We intend to submit a journal article on this matter which, if and when accepted, would replace this report as the authoritative reference for the computations done on temperature-related variables for the 1981-2010 Normals. For information regarding precipitation-related normals or hourly normals (including hourly temperature normals), please review the accompanying documentation.

As described by Menne and Williams (2009) and Menne et al. (2009), NCDC provides monthly temperature data values that have undergone robust quality control and standardization at the monthly timescale. For the 1981-2010 Normals, the approaches described in these papers were applied to monthly maximum and minimum temperature values that were in turn computed from GHCN-Daily values. Monthly values were computed for station-months for which no more than nine missing or suspect daily values were present in GHCN-Daily. The standardization procedures account for both documented and undocumented station moves and other changes in observing practices. Therefore, we give precedence to normals computed from monthly temperature data.
