Uneventful storm.  Looked promising.

Some stations in NJ just set their May monthly maximum high temperature when they reached 100°. In early July multiple stations were within a few degrees of their monthly max for July and all-time high.

Last June Baiting Hollow on Eastern LI reached 103° far from any urbanization and may have been the highest all-time temperature for that area. So all stations regardless of how urbanized they have been experiencing record heat. 

The drier pattern from the 1940s to early 2000s produced monthly maxes in August and September which haven’t been matched. Probably related to the early extreme summer heat in recent years turning wetter as we move into August and September. 

You will notice we had all-time record October heat as recently at 2019 in the mid 90s. That was the result of a flash drought which developed later in the season. 

February 2018 was probably our most extreme monthly max of any month reaching 80° for the first time at the areas away from the cooler ocean influence. A summer extreme of that magnitude would give the usual warm spots a reading in the 110° to 112° range.

 

I've started questioning the accuracy of stations on weather underground, even stations that were formerly reliable seem to have become less so. There's a Davis Vantage Pro 2 in Valley Stream, NY that has been in operation since the 1990s and has closely matched JFKs temperatures but in the last couple of years I've noticed an increasing variance with higher temperatures. In July 2011 it peaked at 102.0 which is fairly close to JFKs peak of 103. Last year in June it peaked at 104.6 when JFK hit 102 on consecutive days. This year it somehow reached 106.8 on one day, 104.7 on another day and 103.2 on the third day when JFKs highs were 102, 100 and 100. Although JFK had three straight days of triple digits to match the record from 1966 I didn't see the peak as being anywhere near as extreme as what 1966 was or even what happened in 2011 or last year for that matter. The Valley Stream weather station even recorded a high of 101.1 on that smoked filled day of July 15th when JFK hit 98. Without the smoke JFK would surely have hit 100 for an unprecedented fourth time but the smoke stopped that from happening and I think the Valley Stream Weather Station was off by a few degrees too. I wonder if these sensors get less accurate with time?

As far as records in October and February go it's definitely much easier to set monthly records at that time than it is to do it in July and August. I'm really not sure if a monthly max of 110 to 112 is possible in our area at the first order sites like EWR and LGA. Those records of 108 and 107 will likely stand for a long time, especially LGAs 107 from 1966. There's nothing even close to that there and EWRs 108 from 2011 also stands apart from the rest. I think the planet sets a natural ceiling for how high the extremes can be even as the averages keep going up, the difference between the min and max just becomes less as those values become compressed.

The was the massive Atlantic ridge >594 DM parked off the Atlantic all of last week a bit to east to bring the persistent mid 90s + and strong heat has been capped since the 14th of July in the area.  

Yes that was a massive ridge Tony but I wouldn't call that a heat dome. Based on past experience for a high to be a heat dome it has to be centered over land. A high centered over water becomes a humidity pump. It's why our hottest temperatures come from the west.

Only 0.01" here today. I was surprised when they issued the watch for us today.

It looks like isolated storms tomorrow afternoon. I would think that SPC should upgrade us to a marginal risk for tomorrow.

agreed - I also think SPC issued that Severe Watch Monday into NJ just to be safe rather than sorry . Looking further down the road if that Bermuda HP sticks around and gets into a favorable position for east coast tropical trouble - the ingredients are showing up in the Atlantic

I think some or many of these WU stations are not installed in favorable areas of a property to get accurate readings for some attached individual instruments . I would not buy one because the only favorable area on my property is on top of my roof - and my roof climbing days ended years ago. Used to have a station there for 20 plus years until Labor Day 1998 - the day the Tornado ripped it off my roof along with my Chimney.
