Where'd the big rainy pattern go-Upton has showers Wed night/Thurs AM and then nothing through the weekend

From Uptons discussion:

.KEY MESSAGE 3...
The next chance for unsettled weather could come this weekend with a
passing offshore low. The GFS and ICON are more aggressive showing
phasing of the northern and southern stream with a surface low
deepening off the Mid-Atlantic coast. This would bring better
chances for seeing wet weather and windy conditions. Both the ECMWF
and GDPS are either offshore or weaker with this system, so there is
plenty of uncertainty. Stuck with NBM slight chance PoPs for now,
since even the more aggressive scenarios bring the low a little too
far offshore.

Suppression depression in May. Hate to see it. I’ll be more than happy to salvage a weekend though.

that's where strong blocking can help-keep it all south!

It will be interesting to see if the coming El Niño can shift us out of this dry pattern which began in September 2024.

You can see how the deficit got erased in NW Jersey since end of Feb.  Been pretty good here.

I'm putting out a call for anyone who has final snowfall totals for the season for their town. There wasn't much after the last update on March 2nd but interior areas may have added a bit to this. 

Let me know via PM or tag me, thanks!

Had a very minor event after then that was a good coating so I guess I’ll go with 52.2”. Thanks for putting the maps together!

Updated discussion

.KEY MESSAGE 2...
An upper level low shifts east and will linger over eastern
Canada, with broad troughing over the eastern US through the
weekend. This pattern will lead to cool conditions, with a
stretch of highs and lows 5 to 10 degrees below normal. Stuck
with NBM temperatures for now, but trends will be monitored as
there will be a few nights across the interior where frost may
be possible.

The offshore low that was mentioned in the previous forecast has
shifted farther in the latest guidance, far enough to lower the
potential for impacts to the area.

[donsutherland1]

Tomorrow will see temperatures reach the lower 60s. Another shot of rain will arrive. A general 0.50"-1.00" rainfall appears likely tomorrow into Thursday. Following the rainfall, temperatures will top out in the lower 60s through Saturday. 

May will likely open with cooler than normal conditions. Sunday could be especially cool with highs only in the upper 50s.

The ENSO Region 1+2 anomaly was +1.5°C and the Region 3.4 anomaly was +0.7°C for the week centered around April 22. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +1.47°C and the ENSO Region 3.4 anomaly has averaged +0.27°C. El Niño conditions will likely develop during late spring or early summer.

The SOI was -15.07 today. 

The preliminary Arctic Oscillation (AO) was +0.394 today. 

Based on sensitivity analysis applied to the latest guidance, there is an implied near 100% probability that New York City will have a warmer than normal April (1991-2020 normal). April will likely finish with a mean temperature near 55.2° (1.5° above normal). 

Supplemental Information: The projected mean would be 2.2° above the 1981-2010 normal monthly value.

Historical:

 

1893: A half-mile wide estimated F4 tornado killed 23 people and injured 150 as it tore a path of devastation through Cisco, Texas. Every building in the town was either destroyed or severely damaged. 

1898: The minimum temperature for the date is 33°F. in Washington, DC and also the latest measurable snow in Washington with 0.5 inches melted 0.29 inches. (Bob Ryan's 2000 Almanac)
 

1921 - A severe hailstorm in Anson County, NC, produced hail the size of baseballs. Gardens, grain fields and trees were destroyed. Pine trees in the storm's path had to be cut for lumber because of the hail damage. (The Weather Channel)

1928 - A coastal storm produced tremendous late season snows in the Central Appalachians, including 35 inches at Bayard WV, 31 inches at Somerset PA, and 30 inches at Grantsville MD. High winds accompanying the heavy wet snow uprooted trees and unroofed a number of homes. The storm caused great damage to fruit trees and wild life. (David Ludlum) (The Weather Channel)

1957: The maximum temperature for the date is 92°F. in Washington, DC. (Ref. Washington Weather Records - KDCA)

1973: The record crest of the Mississippi River at St. Louis, Missouri was registered at 43.23 feet on this day. This level exceeded the previous 1785 mark by 1.23 feet. This record was broken during the 1993 Flood when the Mississippi River crested at 49.58 feet on August 1st. At Memphis, Tennessee, the Mississippi was over flood stage for 63 days, more than that of the historic 1927 flood, and the river was above flood stage for an even longer 107 days at upstream Cairo, Illinois. Out of the seven largest floods on the Mississippi between 1927 and 1997, the 1973 event ranked third in both volume discharged and duration but only sixth in flood height. Over $250 million of damages were incurred mainly in the Mississippi Valley states of Missouri, Arkansas, Tennessee, Mississippi, and Louisiana.

 

1987 - Twenty cities in the western and central U.S. reported record high temperatures for the date. Highs of 95 degrees at Houston TX, 95 degrees at Lake Charles LA, and 94 degrees at Port Arthur TX, were April records. (The National Weather Summary)

1988 - Miami, FL, hit 92 degrees, marking a record eight days of 90 degree heat in the month of April. Squalls produced snow in the Washington D.C. area. Belvoir VA reported a temperature reading of 57 degrees at the time the snow began. (Storm Data) (The National Weather Summary)

1989 - Strong northerly winds and heavy snow ushered cold air into the north central U.S. Snowfall totals in Montana ranged up to 20 inches at Miles City. Thunderstorms produced severe weather from eastern Texas to the Southern Appalachians and the southern Ohio Valley. Hail four and a half inches in diameter was reported at Keller TX and White Settlement TX. (Storm Data) (The National Weather Summary)

1990 - Thunderstorms produced severe weather in the southeastern U.S. during the day. Severe thunderstorms spawned four tornadoes, including one which injured four persons at Inman SC. There were also more than one hundred reports of large hail and damaging winds, with better than half of those reports in Georgia. Strong thunderstorm winds injured four people at Sadler's Creek SC. (The National Weather Summary) (Storm Data) Twenty-nine cities in the northeastern U.S. reported record high temperatures for the date as readings soared into the 80s and lower 90s. Highs of 88 degrees at Binghamton NY, 94 degrees at Buffalo NY, 89 degrees at Erie PA, 90 degrees at Newark NJ, 93 degrees at Rochester NY and 92 degrees at Syracuse NY, were records for the month of April. (The National Weather Summary)

1991: Memphis, Tennessee recorded their wettest April ever with 15.03 inches, breaking their previous record of 13.90 inches in 1872.

2002: During the evening hours, a violent F4 tornado carved a 64-mile path across southeast Maryland. The La Plata, Maryland tornado was part of a larger severe weather outbreak that began in the mid-Mississippi Valley early on that day and spread across portions of the Ohio Valley and the Mid-Atlantic States. In Maryland, three deaths and 122 injuries were a direct result of the storm. Property damage exceeded $100 million. Tornadoes along the Atlantic coast are not frequent, and tornadoes of this magnitude are extremely rare. Only six F4 tornadoes have occurred farther north and east of the La Plata storm: Worchester, Massachusetts - 1953; New York/Massachusetts - 1973; Windsor Locks, Connecticut - 1979; five counties in New York - 1989; New Haven, Connecticut - 1989; North Egremont, Massachusetts - 1995. None was as close to the coast. The tornado traveled across the Chesapeake Bay almost to the Atlantic.

It has been mostly a brown lawn issue here since late 2024. But we did have our local reservoirs running low at times. Thankfully nothing as extreme as the water restrictions areawide back in 2002.

The biggest issue for agriculture this spring has been the record temperature swing. While spring record warmth is arriving earlier these days, the last freeze date has held more steady. This has resulted in the big local crop losses.

Believe a lot of apple orchards in Sussex county and ny got hit hard too.

It's May in the CC era, it doesn't take much to get above normal. 

The pattern is more about keeping the 90+ heat away than enforcing a cool pattern 

[donsutherland1]

It will be rainy tonight into tomorrow morning. A general 0.50"-1.00" rainfall appears likely. Following the rainfall, temperatures will top out in the lower to perhaps middle 60s through Saturday. 

May will likely open with cooler than normal conditions. Sunday could be especially cool with highs only in the upper 50s despite partly sunny skies.

For the past six weeks, the ENSO Region 1+2 anomaly has averaged +1.47°C and the ENSO Region 3.4 anomaly has averaged +0.27°C.

(The National Weather Summary) (Storm Data)

1988 - Thunderstorms produced large hail and high winds in central Texas. Baseball size hail was reported at Nixon, and wind gusts to 70 mph were reported at Cotulla. Heavy rain in Maine caused flooding along the Pemigewassett and Ammonoosuc Rivers. (The National Weather Summary) (Storm Data)

1989 - Thunderstorms produced severe weather in Arkansas, Louisiana and eastern Texas, with more than 70 reports of large hail and damaging winds. Softball size hail was reported at Palestine TX.

1990 - A storm system crossing northern New Mexico blanketed parts of the Rocky Mountain Region and the Northern High Plains with heavy snow, and produced blizzard conditions in central Montana. Much of southern Colorado was buried under one to three feet of snow. Pueblo tied an April record with 16.8 inches of snow in 24 hours. Strong canyon winds in New Mexico, enhanced by local showers, gusted to 65 mph at Albuquerque. Afternoon temperatures across the Great Plains Region ranged from the 20s in North Dakota to 107 degrees at Laredo TX. (The National Weather Summary) (Storm Data)

Farmingdale only starts in 1999 so several warmer rankings prior to that would be missing. Islip finished 12th warmest. The strong onshore flow kept LI cooler in the rankings than NYC.

Did pretty well here with .68" rainfall last evening into the overnight.

Total for April: 3.68".  Not bad but 60% of that total came this week.  Month prior to this final week of the month was very dry.
