58 down from 60...back door front clouds...

very few years had its coldest April Temperature at the end of the month...back in 1966 and 1967 April had late month cold...both years had record cold in May...2020 had its coldest April temp around the 22nd but had an additional cold day near the end of the month...It snowed a little in May 2020 with a benchmark record low...

the last two Mays had an unseasonably cold period with record cold Temperatures...there is a possibility NYC sees upper 30's before the month ends...will it be the last 30's NYC sees until the fall?...Or will May have winters last gasp before countless 90 degree days with humidity...

no snow on the ground in Dingmans Ferry or Milford PA got here yesterday at 3pm...had some graupel yesterday...

when I drive on I 287 near Piscataway it always the hottest spot...

if there were tall buildings to the north of an obs sight the reflection off the buildings would raise the temperature some...those buildings have to be heated and cooled adding to the warmth around them...

NYC's average temperature went up after every building boom era...the building boom is expanding in all directions including up...look at Long Island City today compared to 30 years ago...LGA might be feeling its effects...

nothing beat checking a mercury thermometer in a shelter big enough for all instruments...I don't like those little heat shields that are used now...

they lose in all kinds of weather...

I'm at the bottom of a hill to my west...

hit 90 imby...87 now...

why can't they do that around the Central Park observation spot...

the lowest temperature for NYC and Newark is in the upper 30's which would be a very high April minimum...It is possible the area could see the coldest temperatures of the month still ahead...

yeah 25 degrees isn't what it used to be ...

Newark NJ's least total annual minimums since 1955-56...2021-22 comes in 12th... 2011-12...53 1972-73...58 2001-02...59 2015-16...60 1990-91...64 1998-99...65 2019-20...65 2016-17...66 1997-98...67 1999-00...68 1994-95...70 2021-22...71 2009-10...72 1973-74...74 1983-84...74

just had what looked like wet flakes falling for a brief time...only in the spring can you see snow reach the ground with temperatures in the upper 40's...

just had some hail from a small cell over me...heavy stuff for five minutes...

the 1930's had five years that had a hundred degree temperature in NYC...the 1940's had three...the 1950's had five and had four straight years...the 1960's had one year...the 1970's one...the 1980's one...the 1990's had four...the 2000's had one...the 2010's had three...2020's have none so far... average annual max temp for NYC by the decade... decade...ave ...days 100 1870's...94.6.......0 1880's...95.2.......1 1890's...96.7.......1 1900's...94.7.......2 1910's...97.3.......5 1920's...96.6.......2 1930's...99.3.......8 1940's...98.5.......8 1950's...98.1.....12 1960's...97.3.......4 1970's...96.5.......3 1980's...97.6.......2 1990's...97.9.......8 2000's...95.5......1 2010's...97.5.......5 2020'a...97.0.......0 so far...

in 1965 this storm would have been called a deluge...now its just another run of the mill rainstorm...

before 1980 the wettest April storm was from 1909...the last 40 years or so has eight storms with more precipitation than 1909...

the 1980's had five storms on the list...it had the wettest April Decade...
