Records:

Highs:

EWR: 92 (2002)
NYC: 92 (2002)
LGA: 89 (2002)
JFK: 86 (2003)


Lows:

EWR: 26 (1943)
NYC: 29 (1928)
LGA: 31 (1943)
JFK: 32 (2014)


Historical:
 

1849: Charleston, South Carolina recorded their latest freeze ever with a temperature of 32 degrees while 6 inches of snow fell at Wilmington, North Carolina. Snow fell as far south as Milledgeville, Georgia. A damaging hard freeze occurred from Texas to Georgia devastating the cotton crop. 

 

1851: "The Lighthouse Storm" of 1851 struck New England on this date. Heavy gales and high seas pounded the coasts of New Hampshire and eastern Massachusetts. The storm arrived at the time of a full moon, and high tide was producing unusually high storm tides. The storm was so named because it destroyed the lighthouse at Cohasset, Massachusetts. Two assistant lighthouse keepers were killed there when the structure was swept away by the storm tide.

1851 - The famous "Lighthouse Storm" raged near Boston Harbor. Whole gales and gigantic waves destroyed Minot Light with its two keepers still inside. The storm resulted in great shipping losses and coastal erosion. (David Ludlum)

1880 - A tornado near Marshall, MO, carried the heavy timbers of an entire home a distance of twelve miles. (The Weather Channel)

1933 - Franklin Lake, NH, was buried under 35 inches of snow. (Sandra and TI Richard Sanders - 1987)

1960 - A wind gust of 70 mph was measured at the Stapleton International Airport in Denver CO, their highest wind gust of record. (The Weather Channel)

1987 - A slow moving storm system produced heavy rain over North Carolina and the Middle Atlantic Coast States. More than six inches of rain drenched parts of Virginia, and flooding in Virginia claimed three lives. Floodwaters along the James River inundated parts of Richmond VA. (The National Weather Summary) (Storm Data)

1988 - A storm in the northeastern U.S. produced a foot of snow at Pittsburg VT. Severe thunderstorms produced baseball size hail and spawned five tornadoes in the Southern High Plains Region. (The National Weather Summary) (Storm Data)

1989 - A cold front, ushering sharply colder air into the north central U.S., brought snow to parts of Montana and North Dakota. At midday the temperature at Cutbank MT was just 22 degrees. (The National Weather Summary) (Storm Data)

1990 - Thunderstorms developing along a stationary front produced large hail and damaging winds across Oklahoma, with 99 reports of large hail and damaging winds during the evening and early nighttime hours. Thunderstorms produced baseball size hail south of Carney, and wind gusts to 100 mph in the Oklahoma City area which swept away many Federal tax returns being transported from a mail cart to a waiting truck about the time of the midnight deadline. Will Rogers Airport in Oklahoma City reported a record wind gust of 92 mph. (The National Weather Summary) (Storm Data)

 

This was the start of the historic 2002 heatwave, one of my all time favorite April memories! 12 years after that, JFK's latest freezing temperature on record!

Also, it's times like this that I wish for data going further back for NYC, I wonder if NYC got any snow in this 1849 snowstorm?

I boarded that train a month ago! 

At least the warm part of it.  I'm not rooting for endless dryness.

I like the idea of storms not outstaying their welcome.  6 days of sunshine every week with temps between 65-70 is fine with me and one day of rain every week with temps no lower than the 50s.

Looks like the cutter next week won’t be as strong. So our next run on 80° this weekend won’t be followed by such strong winds. Then another chance of approaching  80° next week. So improving spring conditions going forward. 
 

 

wow it looks like down on the south shore we'll get close to 80 too,  not as warm as March 30th, but this is pretty close and not followed by a super cold front dropping temps by 40 degrees later.

The Euro has a WSW flow on Saturday ahead of the cold front. So so Western LI north of the Southern State could approach 80°. JFK should be able to go 75°+ but not sure about 80° yet since there could be a short trajectory off the water.

Wind direction is key for the Island, as you know, this time of year for any warmth.  Keep the Westerly winds blowing & hold off the seabreeze as long as possible.

Most of the springs summers living back in Long Beach before I moved featured onshore flow. But occasionally we would get into W or WNW flow like 1993,1999, 2010, 2011, and 2012. Those were the occasions when we reached close to or made it to 100°. Even here along the CT Shoreline still get into an onshore flow much of the time as I only had 9 days reach 90° last summer vs 40 days in parts of NJ.

Just had a pretty strong gust that threw around some stuff in my backyard. I’d say close to what we had yesterday.

This one is more constant.  Yesterday (after 4:30 pm) it was like, one gust and then 10 minutes later another gust, etc lol.

I wonder if your new location hits 100 more often than your old location does, Chris?

The years to look at would be the 5 years you mentioned (and also 2013).

New Haven hasn’t made it to 100° since 2011 due to all the onshore flow from the ridge extending east of New England. I am just to the east of the ASOS. So my temperatures are pretty similar.

It’s possible but there was missing data from 1978 to 1999 with no records over those years.

JFK, only 95, how is that possible.  In July 2011 when NYC hit 104, JFK was at 103.

 

The reason for relocating the ASOS to under the trees was to keep people from stealing the weather equipment?

It doesn't make any sense why they would put it there.

There was a sea breeze in July 1977 along the South Shore which kept JFK cooler. But the South Shore was warmer with the late August 1973 heatwave. Those were the two big 1970s heatwaves.

wow I'm really going to miss that Mineola COOP =\

[donsutherland1]

Tomorrow will be another cool day with highs in the upper 50s to near 60°. Afterward, it will turn warmer.

Saturday could be unseasonably warm with readings soaring into the 70s in the New York City area. Some of the warmer spots in New Jersey could approach or reach 80°. The mild weather will continue into at least the start of next week. It will also remain mainly dry into at least early next week.

The ENSO Region 1+2 anomaly was +1.2°C and the Region 3.4 anomaly was -0.1°C for the week centered around April 9. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +1.25°C and the ENSO Region 3.4 anomaly has averaged +0.33°C. Neutral ENSO conditions will likely continue through at least late spring.

Early indications are that summer 2025 will be warmer than normal in the New York City and Philadelphia areas. The potential exists for a much warmer than normal summer (more than 1° above normal).

The SOI was -3.17 today.

The preliminary Arctic Oscillation (AO) was -0.671 today.

Based on sensitivity analysis applied to the latest guidance, there is an implied 57% probability that New York City will have a cooler than normal April (1991-2020 normal). April will likely finish with a mean temperature near 53.1° (0.6° below normal).

Have to disagree.  It sucks.  It was mostly cloudy, windy and temperatures in my part of NJ only got into the m/u 40's. 

This weather blows chunks for mid April.  The constant wind is beyond tiresome.

I found a wx map for Apr 16 1849, looks like NYC may have seen some snow or sleet showers in a very cool NW flow,  but the s.e. coastal snow was associated with a low off the coast that did not move n.e., it weakened and the cold n.w. flow continued over NYC region for two days. Probably 4/16/1849 was close to 39/29 .05" prec 0.1" snow. NW 20-35.
