True, but the upper 90’s with dews in the 70’s that we do get are pretty much equivalent to 110+.

My highest recorded temp since I moved here is 99.3 in 2018, only 0.2 shy of what I’d consider 100.

ah you missed the big heat in 2010 and 2011.  Was up in the low 100s then all the way out to Suffolk County.  We were over 100 three days out of four in July 2010 around July 4th weekend and then in late July in 2011 we did it two more times and peaked at 104.

It hit 90 here at 1:15 the temps didn't start dropping until after 1:20.

I hate the sea breeze but a positive of wind energy is if we can harness its power we can use up that energy before it makes here correct?  So if we divert the wind away from the coast with wind turbines we can stop the sea breeze from ruining our heat party?

 

The heat index at Newark today was the highest in May since 1996. Came within a few degrees of  the all-time highest May record of 102°.

Yeah but this isn't the "strong" kind of heat that lasts all day.  Back in 2010 and 2002 and 1996, the heat was so strong that it would make it all the way to the coast and stay there all day.  This time around it made it to the coast for like 30 min (when I hit 90) and then retreated.

That's basically what I was asking you, why is it that in some years you get that kind of heat and then you have other times when the heat just touches the coast and then it retreats....is it down to the position of the high?

High dews high min heat since 2011 that frequently makes it into the top 5 hottest months is no small feat.

tainted by high mins, I only measure heat by high temps and number of 90 degree days.

it's why you don't see any global heat records coming out of tropical rain forests lol

Elongation of the ridge to the east of New England in recent years has been causing more frequent onshore flow. Notice how much flatter the ridge was back in May 1996. So it allowed a deep westerly flow from the Midwest right out across Long Island.

so back then with the widespread westerly flow, is that what's known as a "Sonoran Heat Release"-- I noticed that's when we get our hottest weather, like what happened in July 2010 and July 2011.

damn you missed the heat party.  Were you keeping track of your car thermometer.....when did the big drop in temp occur?  Were you south of Sunrise Hwy when it happened?

Seemed like it was between the Southern State and Sunrise Highway that the big drop happened. I didn’t mind leaving my place to come down here, it felt atrocious there. August like.

First forced OT of the warm season, it definitely didn’t disappoint, got 6 no AC calls, one was frozen in a block of ice lol. My digital thermo was reading 94-95 in South Brunswick at 2PM. Am home now enjoying some cold beers.

That’s a result of the ASOS being improperly located under dense vegetation. It’s common for NYC to try and play catch up when the sun dries wet morning vegetation. But NYC ultimately fell 3° short of the NWS official forecast high of 93°. I don’t think that the NWS applies any deep shade correction to their forecast for NYC. That’s why they usually do much better with their forecasts for the other sites than Central Park.

wait, I'm confused, are the numbers on the left the forecast highs and the numbers on the right the actual highs?

I didn't see what the actual highs today at the airports and the park were.

Much of the region sizzled under near record to record heat. High temperatures included:

Albany: 92° (tied record set in 1941)
Atlantic City: 93° (tied record set in 1996)
Baltimore: 95°
Islip: 90° (tied record set in 1996)
New York City-JFK: 87°
New York City-LGA: 91°
New York City-NYC: 90°
Newark: 95°
Philadelphia: 95° (tied record set in 1934)
Richmond: 95° (old record: 93°, 1934 and 1962)
Scranton: 90°
Sterling, VA: 92° (tied record set in 1996)
Washington, DC: 92°
Wilmington, DE: 95° (tied record set in 1996)
Worcester: 88° (tied record set in 1975)

New York City's first 80° or above temperature of the year was 90°. Only 1918, 1927, and 2010 saw 90° or above readings as Central Park's first 80° or above temperature. Records go back to 1869.

Islip also saw its first 80° or above temperature of the year with a high of 90°. Only 1969 saw the first 80° temperature wind up as the first 90° or above temperature. Records go back to 1963.

In Europe, Andujar, Spain recorded its second consecutive high of 107° in what is unprecedented May heat. The historic spring heat also continued in parts of India and Pakistan. Jacobabad reached 120° for the third consecutive day.  

Tomorrow will be another hot day. Areas on the immediate coastline where sea breezes occur may remain much cooler than interior sections. New York City and Newark could again see the mercury rise into the upper 80s and lower 90s. Thunderstorms are possible late in the day and during the evening as a cold front moves across the region.

Behind the cold front, a much cooler air mass will overspread the region. During the middle of next week, high temperatures could struggle just to reach 70° in parts of the northern Middle Atlantic region.

Overall, the second half of the month will likely be warmer than normal and there remains some possibility of an overall warm monthly outcome. The potential also exists for several very warm to perhaps hot days.

The ECMWF seasonal forecast indicates that the summer will be warmer than normal throughout the region and across much of North America.

The ENSO Region 1+2 anomaly was -1.4°C and the Region 3.4 anomaly was -1.1°C for the week centered around May 11. For the past six weeks, the ENSO Region 1+2 anomaly has averaged -1.57°C and the ENSO Region 3.4 anomaly has averaged -1.03°C. La Niña conditions will likely persist into the start of June.

The SOI was +6.34 today.

The preliminary Arctic Oscillation (AO) was +0.427 today.

On May 19 the MJO was in Phase 8 at an amplitude of 1.303 (RMM). The May 18-adjusted amplitude was 1.261 (RMM).

Based on sensitivity analysis applied to the latest guidance, there is an implied 57% probability that New York City will have a warmer than normal May (1991-2020 normal). May will likely finish with a mean temperature near 63.6° (0.4° above normal).

Good evening Don. CPK reached 90, EWR 95. I wonder how many CPK high temperature records were lost to the forest? Stay well, as always ….

Wow I wonder if we may see some global records with these extreme worldwide temperatures.  I remember reading that April was the hottest on record in southern Asia.  Do you have any global high heat record notifications, Don?  Any that are 125 or higher?
