The temperature reached 88° in Central Park and 90° in Newark. Reading, PA had a high of 96°, which was 1° short of its May monthly record. Even hotter temperatures are likely tomorrow in the East.

Temperatures will then rocket well into the 90s tomorrow. Wednesday will be another hot day with highs in the 90s. Even as tomorrow and Wednesday coincide with historic 1962 and 1996 May outbreaks of extreme heat in the Northeast, parts of the region could still approach or reach record values. 

Records for May 19th:
Albany: 91°, 1903, 1962, 1986, 1989
Allentown: 97°, 1962

In addition, 2026 will become Central Park's second year on record that saw a monthly maximum temperature of 80° or above in March, and 90° or above in both April and May. Currently, 1977 with a March high of 81°, April high of 90°, and May high of 92° is the only such year. 2026 has seen a March high of 81° and April high of 90°.

Thursday will see temperatures top out in the lower 70s. Afterward, it will turn much cooler with highs only in the 60s on Friday and Saturday.

The ENSO Region 1+2 anomaly was +1.8°C and the Region 3.4 anomaly was +0.9°C for the week centered around May 13. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +1.63°C and the ENSO Region 3.4 anomaly has averaged +0.70°C. El Niño conditions are now in place. The ongoing El Niño will continue to strenthen through the summer.

The SOI was -6.11 today. 

The preliminary Arctic Oscillation (AO) was +0.583 today. 

Based on sensitivity analysis applied to the latest guidance, there is an implied near 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). 

Supplemental Information: The projected mean would be 1.1° above the 1981-2010 normal monthly value.

79 / 68 the hear is on the next 36 hours.  Mid - upper 90s , stray 100s today.  Tomorrow just as hot if the front is later in the PM, otherwise the caveat is a bit cooler.  Showers, storms.  Front sags and stalls , upper trough cuts off in an otherwise strong ridge, stuck beneath clouds, showers, rain , easterly flow Thu- Sun.  Perhaps we can salvage Memorial Day.  rain >1 - 2.00 is possible between the cold front wed and Sunday.  Ridge remains achored in the east and quick rebound into the 80s by Tuesday.  Euro backs in the cut off but will see, overall warmer once passed the abysmal period coming up. 5/26 - beyond looks above normal.

Remember these?

 

They rarely make it this far east anymore.

Any guesses on how much precip we will receive  tomorrow region wide?

 

There's a chance of a line forming giving the clash of air masses.  Typically those lines are broken up and not well organized, at least by the time they get here.  So I'm going to guess, overall, not much (<0.2") for the majority of the sub.

Historical:
 

1780 - The infamous "dark day" in New England tradition. At noon it was nearly as dark as night. Chickens went to roost, and many persons were fearful of divine wrath. The phenomena was caused by forest fires to the west of New England. (David Ludlum)

 

1915: A spring storm came to an end after producing widespread snow. Total snowfall from the storm included: 17.6 inches in Scottsbluff, NE, 8 inches at Cheyenne, WY and 7 inches at Chadron, NE.

1955 - Lake Maloya NM received 11.28 inches of rain in 24 hours to establish a state record. (The Weather Channel)

 

1962: A heat wave gripped the East Coast with high temperatures reaching 99° at New York City, 98° at Baltimore, MD and 96° at Philadelphia, PA (all either broke or tied records for the month of May.). Other daily records included: Greenville-Spartanburg, SC: 99°, Newark, NJ: 98°, Concord, NH: 97°, Allentown, PA: 97°, Richmond, VA: 97°, Athens, GA: 97°, Columbus, GA: 97°, Philadelphia, PA: 96°, Atlantic City, NJ: 96°, Roanoke, VA: 96°, LaGuardia, NY: 95°, Harrisburg, PA: 95°, Wilmington, DE: 95°, Charlotte, NC: 95°, Raleigh, NC: 95°, Nashville, TN: 95°, Hartford, CT: 94°, Lynchburg, VA: 93 °F.

1975 - Thunderstorms produced golf ball size hail and wind gusts to 110 mph in Minnesota, between Fridley and Hugo. Fifty persons were injured. The hail and high winds destroyed fifty mobile homes, and a dozen aircraft, and also destroyed a third of the Brighton Elementary School. (The Weather Channel)

 

1977: Over a 9 day period, this was the fourth day of a terrible heat in the Chicago, IL area. Over the 9 day period, the daily high temperature was 90° or higher setting eight high temperature records. The monthly average for those 9 days was 69.3° or about 20 degrees above normal.

1987 - Thunderstorms in Texas produced thirteen inches of rain northwest of Lavernia. The heavy rain, along with golf ball size hail, destroyed eighty percent of the crops in the area, while high winds toppled trees. Golf ball size hail was also reported south of Dallas and around San Antonio. Up to eight inches of rain drenched Guadelupe County. (The National Weather Summary) (Storm Data)

1988 - Severe thunderstorms in southwest Texas produced hail as large as tennis balls around Midland, with the hail accumulating up to a foot deep. Showers and thunderstorms in the Middle Atlantic Coast Region produced 3.5 inches of rain near Schuylkill PA. (The National Weather Summary) (Storm Data)

1989 - Thunderstorms developing ahead of a cold front spawned ten tornadoes from Illinois to Tennessee during the afternoon and night. Snow, wind and cold prevailed in the Northern Plateau Region and the Northern Rockies. Dixie, ID, was blanketed with nine inches of snow, winds gusted to 87 mph at Choteau MT, and the temperature at Crater Lake, OR, dipped to 11 degrees. (Storm Data) (The National Weather Summary)

1990 - Thunderstorms deluged Hot Springs AR with thirteen inches of rain in nine hours resulting in a devastating flood. Two waves of water, four to six feet deep, swept down Central Avenue flooding stores and the famous bathhouses on Bathhouse Row. Water released from Lake Hamilton devastated the area between it and Remmel Dam. The 500 foot Carpenter Dam Bridge across Lake Catherine was completely washed away, as were cabins and mobile homes near the lake, many of which flowed right over the top of Remmel Dam. (The National Weather Summary) (Storm Data)

1997: Record maximum temperature for Washington, DC for the date is 96 °F. (Ref. Washington Weather Records - KDCA)

2002: Key West, FL recorded 4.02 inches of rain in 24 hours as a slow moving band of storms lingered over the area. Their average May precipitation is 3.31 inches.
Snowflakes flew across Lower Michigan as record cold weather prevails. Record lows include the 26° at Lansing, 29° at Muskegon and 30° at Grand Rapids. The freezing temperatures cause heavy losses to orchards across western Lower Michigan. Meanwhile on the same day Fairbanks, AK reached 77°. (Ref. Wilson Wx. History)

2008Southwest:Even by American desert standards, the searing heat is one for the books. Death Valley, California sizzles at 120 °F while residents of Phoenix, Arizona witness the year's first high of 110 °F. (Ref. WxDoctor)

2009Minnesota: At 4 PM ,Granite Falls in southwestern Minnesota bakes with a temperature of 100 °F while residents of Grand Marais on the Lake Superior shore shiver with a 34 °F (a difference of 66 °F). (Ref. WxDoctor)

2018: May 19th had 0.50 inches of rain a 9-year daily record for the date; the previous record was only 0.09 in 2015. Glen Allen would get 9.20 inches of rain by the time this Weather system had finished on the 19th. This was from moisture come up the coast from Florida with a stationery just north of central Virginia. Also more than 10 inches of rain fell in SW Henrico County during a 4 day period of May 16 to May 19th. (Ref. Richmond Times Dispatch)

My weather station always runs a little hot. It hit 100 a little while ago, but saw a few other stations within a few miles at 97-98 so its not off by much. 

Mine and the 3 others on my road all were between 94-95.
