Cooler conditions have returned to the region. Temperatures will likely top out in the 50s through Thursday. Highs tomorrow will struggle to reach the lower 50s. 

Tomorrow morning could see the low temperature approach 32° in New York City. Should the mercury reach 32°, New York City would see its second consecutive April with a freeze (last year's last freeze was April 9). The last time that happened was 2015 and 2016.

Temperatures will return to the 60s on Friday. The warmth will extend into the weekend. It could turn even warmer next week.

The ENSO Region 1+2 anomaly was +1.2°C and the Region 3.4 anomaly was +0.2°C for the week centered around April 1. 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 0.00°C. Neutral ENSO conditions will continue through at least mid-spring.

The SOI was -9.23 today. 

The preliminary Arctic Oscillation (AO) was +0.944 today. 

Based on sensitivity analysis applied to the latest guidance, there is an implied near 66% probability that New York City will have a warmer than normal April (1991-2020 normal). April will likely finish with a mean temperature near 55.5° (1.8° above normal). 

Supplemental Information: The projected mean would be 2.5° above the 1981-2010 normal monthly value.

Don't you mean April? And I think these temperatures are severely underestimated. This April looks like it's going to be near record warm.

euro temps aren't ever correct. I would go with mid 80's tops

The cooler Euro Mid 80s in the warmer spots in Central NJ is probably the floor and the Canadian low 90s is the high end potential. Will probably come down to frontal timing and clouds. But the signal is there for the warmest readings of the year so far.

Always take the over on our warmups and take it even higher with dry ground and no foliage on trees

Yeah, we are right on the cusp of leaf out. Once that happens evapotranspiration increases dews and lowers higher end temp potential. We can even rapidly warm up right to the coast pre leaf out before the sea breeze kicks in.

38 / 15 after a low of 27.  Coolest slowly getting behind us as we move into a warm to very warm period overall starting Friday. Warmest period of the next week to 10 days is 4/12 - 4/15.  Overall 7 days period Friday to Friday will likely neet a +10 to +15.

Historical:


1862: Snow at Atlantic City, NJ was deep enough to support an early spring sleigh ride. (Ref. Wilson Wx. History)

1918: A big spring snowstorm buried the Potomac Highlands of West Virginia with 34 inches of snow at Wardensville, 30 inches at Moorefield, and 29 inches at Romney. (Ref. Wilson Wx. History)
 

1919 - A tornado swarm in northern Texas resulted in the deaths of 64 persons. (David Ludlum)

1926 - The lightning-set oil depot fire near San Luis Obispo CA boiled over and engulfed 900 acres. Many tornado vortices resulted from the intense heat of the fire. One such tornado traveled 1000 yards, picked up a house and carried it 150 feet, killing the two occupants inside. (The Weather Channel)

 

1929: EARLY HEAT WAVE-The maximum temperature for the date is 93°F. in Washington, DC. Heat wave set three records in a row 92°, 94°, 93° on the 6th-8th in Washington, DC. (Ref. Washington Weather Records - KDCA)

1938: Snow began to fall over central Oklahoma during the previous evening and continued to this day. In Oklahoma City, several snowfall records for the month soon fell to the storm, including the record for most total snowfall during the month of April. The Oklahoma City snowfall totals of 0.8 inches on the 7th, and 3.3 inches on the 8th, remain daily records. In fact, the 3.3 inch snowfall on the 8th is the most ever to fall on any single April day. The 4.1 inch total for the month continues as the greatest April monthly snowfall total. (Ref. Wilson Wx. History)

1952: A huge ice jam broke up on the Missouri River in North Dakota, resulting in rapid rises of up to 8 feet downstream. The river flow jumped from 75,000 cubic feet per second to over 500,000 cubic feet per second. (Ref. Wilson Wx. History)

1956: After daytime highs in the 60s, snow along with thunder and lightning occurred across southwest Kansas. Over 5 inches of snow fell at Dodge City with 4 inches at Garden City. Winds gusted to over 70 mph in the Texas panhandle with zero visibility and blowing dust. A strong tornado hit near Enid, OK. (Ref. Wilson Wx. History)

1958: The global record for most rainfall in 48 hours was set at Aurere, La Reunion Island beginning on this date from a tropical cyclone when 97.1 inches fell. (Ref. Wilson Wx. History)

Richmond, VA had a high temperature for the day of 37°F matching the coldest April day on record (records since 1897). The other date of 37 °F was April 3, 1915. (Ref. Richmond Weather Records - KRIC)

1973 - A severe storm brought high winds and heavy snow to Iowa. Belle Plain received 20 inches of snow, and 19 inches blanketed Dubuque, record totals for both locations for so late in the season. Snow drifts up to sixteen feet high closed highways. (David Ludlum)

1982: The minimum temperature for the date is 29°F. in Washington, DC tied with 1972. (Ref. Washington Weather Records - KDCA)
Severe crop and property damage occurred from a major hailstorm in Seminole Co, FL. (Ref. Wilson Wx. History)
 

1987 - A cold front crossing the Northern Plateau and the Northern Rocky Mountain Region produced high winds in northeastern Wyoming. Winds gusting to 69 mph at Sheridan WY downed power lines and caused some property damage. (The National Weather Summary) (Storm Data)

1988 - Strong northerly winds ushered cold air into the north central U.S. The strong winds, gusting to 60 mph at Rapid City SD and Williston ND, reduced visibilities in blowing dust over the Dakotas. (The National Weather Summary) (Storm Data)

1989 - Two dozen cities in the southwestern U.S. reported new record high temperatures for the date. Phoenix AZ equalled their record for April of 104 degrees established just the previous day. (The National Weather Summary)

1990 - Twenty-two cities reported record low temperatures for the date as readings dipped into the 20s and 30s across much of the eastern U.S. Freezing temperatures severely damaged peach and apple orchards in West Virginia, where prolonged mild weather since January had caused an early blooming of spring vegetation. State and Federal agencies estimated a 50 percent loss in production for peaches and "Delicious Red Apples". (The National Weather Summary) (Storm Data)

 


1994: 7 to 9 inches of rain fell over a 3-day period causing the Missouri River at Boonville, MO to rise 14 feet and at Hermann, MO to rise 19 feet. (Ref. Wilson Wx. History)

1996: The first of two late season heavy snowfalls in only three days over the Northeast dumped 12 inches of snow at Slide Mountain, NY, 10.2 inches, at Ashburnham, MA, and 7 inches at Falmouth, Massachusetts. The 6.1 inches at Binghamton, NY brought its seasonal snowfall total to 131.8 inches; their snowiest winter ever. Incredible flooding continued on the Minnesota River in Minnesota. Thousands of people were driven from their homes by the flooding, which was complicated by blizzard conditions and record cold.
(Ref. Wilson Wx. History)

1997: Miles City, MT only reached 5° tying their coldest April reading ever with 4/15/1986. They did not reach 30° from the 5th through the 10th. (Ref. Wilson Wx. History)

The tornado lifted just two miles from downtown Birmingham. The twister had a track of 20 miles with the damage path averaging between ½ and ¾ of a mile in width. 34 people were killed, 221 injured and 1,000 homes were destroyed. (Ref. Wilson Wx. History)
An F2 tornado destroyed a mobile home near Coal City, Alabama. The clothes dryer was found 250 yards from the home site-with a 3 year old girl inside it. Evidently her parents had put her in it hoping she would survive (she did). Unfortunately the parents were killed by the tornado. (Ref. Weather Guide Calendar with Phenomenal Weather Events 2012 Accord Pub. 2011, USA)

1999: A windstorm caused $20 million dollars in damage along the front range from Fort Collins, CO south to Pueblo, CO and to the east over the Plains. This storm was equal to the costliest windstorm on record occurring on 1/17/1982 at Boulder, CO. In the Denver area, there was damage to homes including roofs, broken fences, awnings, doors and windows. Multiple accidents resulted including several tractor-trailers blown on their sides. Power lines were downed causing a few small grass fires. The highest wind gusts reached 112 mph atop the Niwot Ridge near the Continental Divide west of Boulder, 102 mph at Wondervu, 100 mph at NCAR in Boulder. Winds of 98 mph were recorded at the National Wind Technology Center near Broomfield, 96 mph on Rocky Flats, 92 mph at the Jefferson County Airport.
Several tornadoes touched down across central Illinois, as a complex of severe thunderstorms moved across the region. In Hancock County, the town of Hamilton had significant damage, with 144 homes destroyed or damaged by a tornado of F3 strength. Two radio and TV towers were also destroyed. Damages totaled to about $10 million. In far southeast Cass County, one person was killed in Ashland, when a tornado hit a trailer park. Damage in Ashland was estimated around $1.8 million dollars. Further east, another tornado destroyed a trailer north of Cisco, killing a second person. Five separate tornadoes caused F2 damage in Knox, Boone, Lewis, and Pike counties in Missouri and Pike County in Illinois. Seven people were injured. (Ref. Wilson Wx. History)


2003: A severe thunderstorm with wind-driven hail up to 3 inches in diameter hit Brownsville, Texas, injuring 5 people and causing $50 million dollars in damage. It was one of the most destructive hail events ever for the city. (Ref. Wilson Wx. History)

2013: The 8th of the top 10 US weather events of 2013 was a Great Lakes winter storm and plains of April 8 through the 12th. An enormous storm system tracked from the Great Basin to the Great Lakes, dropping over a foot of snow from Wyoming to Minnesota, including 28 inches at Rapid City, South Dakota-an all-time record. This storm also hit the plains and South with large hail and tornadoes and spread severe thunderstorms from Texas into Pennsylvania. (Ref.Weatherwise May/June 2013 page 15)
