1912: Ponca City, OK was struck by an F4 tornado. One person was killed and 119 homes were damaged or destroyed. Dozens of oil derricks were flattened or twisted, southwest of town. The tornado was reportedly visible and audible for 20 miles. (Ref. Wilson Wx. History)

1920 - Atlanta, GA, received 1.5 inches of snow, and experienced their latest freeze of record with a morning low of 32 degrees. The high of just 39 degrees was only their second daily high colder than 40 degrees in April. (The Weather Channel)

1925: The maximum temperature for the date is 96°F. at the Richmond International Airport and the highest for the month and also occurred on four other dates. (Ref. Richmond Weather Records - KRIC)

1984 - A late season snowstorm struck the Northern Rockies and the Northern Plains. The storm produced some unsually high snowfall totals. The town of Lead, located in the Black Hills of western South Dakota, was buried under 67 inches of snow. Red Lodge, located in the mountains of southern Montana, reported 72 inches of snow. Up to 60 inches blanketed the mountains of northern Wyoming. It was rated the worst late season storm of record for much of the affected area. (25th-28th) (Storm Data) (The Weather Channel)

 

1986: Chicago, IL recorded high temperatures of 90 °F on this date and the 26th. Besides setting back-to-back records on both dates, this was the second April in history to record temperatures of at least 90 °F on two days. The previous year was 1952. Quincy, IL set the high temperature record for April when the high reached 92°. Springfield, IL tied their April record with 90°. (Ref. Wilson Wx. History)

1987 - Low pressure off the coast of North Carolina produced heavy rain flooding creeks in the foothills and the piedmont area, before moving out to sea. The low pressure system also produced wind gusts to 50 mph in Virginia. (The National Weather Summary) (Storm Data)

1988 - Thunderstorms racing at 65 mph produced large hail in Alabama and Georgia. Hail damage in Alabama was estimated at fifty million dollars, making it their worst weather disaster since Hurricane Frederick in 1979. Hail three inches in diameter accompanied a tornado near Valdosta GA. Hail four and a half inches in diameter was reported south of Atlanta GA. (The National Weather Summary) (Storm Data)

1989 - Thunderstorms developing along a stationary front produced severe weather from North Carolina to Indiana and Ohio, with more than 70 reports of large hail and damaging winds. A strong (F-2) tornado hit Xenia OH injuring 16 persons and causing more than a million dollars damage. (The National Weather Summary) (Storm Data)

1990 - Thunderstorms produced severe weather from Texas to Nebraska. Thunderstorms spawned fifteen tornadoes, including a powerful (F-4) tornado near Weatherford TX. Between 3 PM and 8 PM, a storm complex tracking northeastward across central Kansas spawned four tornadoes along a 119-mile path from Ness to Smith Center, with the last tornado on the ground for 55 miles. Del Rio TX was raked with hail two inches in diameter, and wind gusts to 112 mph. Brown County and Commanche County in Texas were deluged with up to 18 inches of rain, and flooding caused more than 65 million dollars damage. Two dozen cities in the north central U.S. reported record high temperatures for the date. Highs of 87 degrees at Flint MI and 90 degrees at Alpena MI were records for April. (Storm Data) (The National Weather Summary)

1994: Strong winds of 60 to 70 mph created dust storms that reduced visibilities to near zero over parts of southwest Kansas. A dust storm warning was issued which is extremely uncommon. Zero visibility in areas forced vehicles off roadways. A Kansas Highway Patrol spokesman was quoted as saying “it was parallel to whiteout in a snowstorm”. A tornado was reported in Dallas County, Texas killing three people and injuring 27. Damage totaled $200 million dollars. Further north, record rainfall occurred in parts of eastern Minnesota and western Wisconsin. The following locations had their wettest April day on record: Sparta, WI: 3.80", Hokah, MN: 3.55", La Crescent, MN: 3.43", Cashton, WI: 3.22", Ontario, WI: 3.00 inches. (Ref. Wilson Wx. History)

1996: International Falls, MN recorded 9.6 inches of snow in a late season snowstorm. This brought the city's seasonal snowfall to 116.0 inches. This broke the old seasonal snowfall record of 111.0 inches set in 1992-93. (Ref. Wilson Wx. History)

1997: Amarillo, TX recorded 6.5 inches of snow for its greatest April snowstorm on record. (Ref. Wilson Wx. History)

2008 - Anchorage, AK, receives a record 17.2 inches at the airport and 22 inches in northeast Anchorage from the 25th to 26th. The 15.5 inches on the 25th makes it the third most received on any one day in Anchorage.

Gotta love 1874...

1.12”. Things will pop nice and green this week when we hit low 60s. 

[Prue11]

Good rainfall, as much as it sucks real good for the ground

[NorthShoreWx]

Up to 1.46” on the Ambient.  Drawn out rain like this is probably about the best way to get an inch and a half on dry ground.  

40⁰ and rain continues.

I'm a longtime follower and infrequent poster who grew up on the South Shore but now lives in Huntington Station. I'm a little confused by the complaints about this spring. Maybe it's because I'm used to the relentless sea breezes on the South Shore, but this spring has been well above average in terms of temperature and overall weather.

My ambient station, which is well-sited and typically runs highs somewhere between LGA and FRG, is showing an average high temperature of 57.3 from March 1 through today: 52.6 in March and 63.4 in April. That feels closer to a Central Jersey spring than a Long Island one.

Even the data that @bluewave shared shows JFK/ISP at 55.5/54.3 average spring-to-date, versus normals of 52.7 and 51.9 with precip below normal.

It mostly comes down to the warmest high temperatures staying closer to the interior rather than the coast. So even though Long Island is still having warmer highs than normal for this time of year, It’s around 10° cooler than the Philly to interior NJ corridor. Very strong onshore flow influence with the SSTs still cooler during the spring.

This is great data - i didn't realize how much warmer relative to normal it was in New Jersey PA. I'm on that site now, but can only see basic stations (ISP, NYC, LGA). How do you get it to show the broader set of stations you're displaying?

You usually have to go back a day before to get the broader set to update. On the Xmacis2 site it’s easier to display. Islip had their 12th warmest spring average spring high through the 25th with Philly coming in 3rd place.

Ok, another game for her this morning and it’s 43 and still freaking raining. You’ve got to be kidding me lol. Took us a good half-hour for us to thaw out yesterday. 

[SACRUS]

46 / 42 clouds.  Clouds may hang on beyond noon but clearing later this afternoon.  E/NE flow caps temps in the low-mid 50s.  Reprieve Mon / Tue - nice near normal weather - dry / sunny low - upper 60s.  Next shot at rain Wed into and maybe through much of Thu with >1.00 potential.  Trough figs in to end the week and next weekend which can be unsettled and trend that way.  Overall cooler / unsetteled through May5th.  Beyond there moderation between towards the second week of the month.

Historical:

 

1834 - Killer frosts were reported in the Deep South. The frost was quite severe around Huntsville AL, and highlighted a backward spring in the South that year. (David Ludlum)

1857: Heavy snow in parts of Connecticut caused buildings to collapse. Six foot snow drifts were reported. (Ref. Wilson Wx. History)

1884: Tornadoes were hard to capture on old cameras with their hard to use glass plate negatives. The first recorded photograph of a tornado was taken on this date by A.A. Adams near Garnett, Kansas. 

1890: Very destructive rain, wind and hailstorm at Baltimore doing $100,000 in damage.

1899: A tornado struck Kirksville MO killing 34 persons and destroying 300 buildings. (David Ludlum)

1912: One of the worst tornado outbreaks in Oklahoma's history occurred. 16 tornadoes rated F2 or greater touched down in the state with 6 of them rated F4. 29 people were killed. (Ref. Wilson Wx. History)

1915: The maximum temperature for the date is 95°F. in Washington, DC. (Ref. Washington Weather Records - KDCA)
The maximum temperature for the date is 96°F. at the Richmond International Airport and the highest for the month and also occurred on four other dates. (Ref. Richmond Weather Records - KRIC)

1922: For two weeks, the city of New Orleans, LA had been under siege from a major flood on the Mississippi River. On this date, a levee failure occurred 12 miles downriver from New Orleans at Poydras in St. Bernard Parish. The Poydras crevasse would become an opening 1,500 feet wide in the levee and flooding Plaquemines and St. Bernard Parishes, but saving New Orleans. As the Corps of Engineers built more and more levees, the river went higher and higher. The 1922 flood was a preview of a worse flood that would occur in 1927. (Ref. Wilson Wx. History)

1923: A tornado moved east from the northeast corner of Baca County, Colorado. Accompanied by two other funnel clouds, the tornado struck the Sherwood school, 14 miles northwest of Johnson Kansas, killing the teacher and injuring five small children. The body of the teacher was carried 100 yards. The prairie grass in this sparsely settled region appeared to be burned. (Ref. Wilson Wx. History)



1933: The minimum temperature for the date is 38°F. in Washington, DC. (Ref. Washington Weather Records - KDCA)
This was the 11th day during the month where the low temperatures at Rockford, IL fell below the freezing mark. The morning low of 26° tied a record low for the date. (Ref. Wilson Wx. History)

1942: A destructive tornado swept across Rogers County and Mayes County in Oklahoma. The tornado struck the town of Pryor killing 52 persons and causing two million dollars damage. (David Ludlum)

1970: Heavy snows fell across Montana, including 39 inches at Red Lodge and 35 inches at Summit. (Ref. Wilson Wx. History)

1978 - An unusually strong occluded front swept out of the Gulf of Alaska and produced the first April thunderstorm of record at Fairbanks. Pea size hail fell northeast of Fairbanks from thunderstorms whose tops were less than 8000 feet. (The Weather Channel)

1984 - Severe thunderstorms associated with an intense cyclone spawned a total of forty-seven tornadoes in two days from Louisiana to Upper Michigan. The tornadoes killed 16 persons and injured 259 others. (Storm Data)

 

1986: The Chernobyl nuclear power station in Kiev Ukraine suffered a massive explosion. The radioactive cloud of particles and gas carried westward and northwestward, contaminating large areas of Europe in the following week.

1987 - Twenty-two cities in the central and western U.S. reported new record high temperatures for the date. The afternoon high of 83 degrees at Astoria OR smashed their previous record by 13 degrees. Sacramento CA hit 94 degrees. (The National Weather Summary)

1988 - While Rochester, MN, was blanketed with 13.7 inches of snow, establishing a single storm record for the month of April, Minneapolis MN, just 90 miles away, got only rain. (Storm Data) (The National Weather Summary)

1989 - Thirty-three cities in the central and southeastern U.S. reported record high temperatures for the date. Afternoon highs of 91 degrees at Evansville IN and Nashville TN equalled April records. Thunderstorms produced severe weather from Iowa to Kentucky, with more than ninety reports of large hail and damaging winds. Thunderstorm winds gusted to 90 mph at Berwick IA. (The National Weather Summary) (Storm Data)

1990 - Twenty-nine cities from the Carolinas to the Great Lakes Region and western New England reported record high temperatures for the date as readings soared into the 80s and lower 90s. Record high temperatures included 95 degrees at Baltimore MD and 92 degrees at Allentown PA. The record high of 89 degrees at Alpena MI was the third out of six straight record highs for that location, and smashed their previous record for the date by ten degrees. (The National Weather Summary)

1991 - Severe thunderstorms in the central U.S. spawned fifty-five tornadoes from northeastern Texas to Iowa and eastern Nebraska killing twenty-one persons. Early evening thunderstorms over south central Kansas spawned a violent (F-5) tornado whiched traveled 45 miles from southwest of Wichita to north of El Dorado. It killed seventeen persons, including thirteen at the Golden Spur Mobile Home Park in Andover. The tornado also caused 62 million dollars damage to McConnell Air Force Base as it crossed the south side of Wichita. (National Weather Summary

1991:During a severe thunderstorm event, large hail fell over parts of Brown, Spink, Hand, and Buffalo Counties. Both Brown and Hand Counties received hail up to 1.75 inches in diameter.


2003: For only the 11th time since records began in 1871, hail was observed in Key West Florida. A severe thunderstorm produced hail to 1.75 inches in diameter which easily broke the previous record of a half an inch in diameter which was set on May 10, 1961.(Weather Guide Calendar with Phenomenal Weather Events 2007 Accord Publishing, USA)

2009 was another one of those years that led into a strong el nino. All the colder Junes in the last 30 years have happened in lead-ups to strong or super el ninos (1997, 2009, and 2023). 1997 and 2009 both finished with well below average summer temps, while 2023 finished near normal.

2015, on the other hand, had a near record warm May, and a warmer than normal summer. Same with 1991. Oddly enough, both years were preceded by borderline warm neutral/weak el ninos. The summers before, 1990 and 2014, were much cooler.

2009 would probably be too big of an ask in this much warmer climate. It was the 2nd coolest June and July on record at spots like Islip.

2023 was our last summer with a developing El Niño that became very strong. Was cooler overall  than the other 2020s summers so far but still not really cool by historical standards.

It does look like May will at least start out cooler than average with all the blocking and the upper low parked over the Northeast. Will be interesting to see if we can get some improvement heading out toward Memorial Day. Still beyond the reach of the models.
