Based on sensitivity analysis applied to the latest guidance, there is an implied near 85% probability that New York City will have a warmer than normal April (1991-2020 normal). April will likely finish with a mean temperature near 56.1° (2.4° above normal). 

Supplemental Information: The projected mean would be 3.1° above the 1981-2010 normal monthly value. 

If this is true, then the last part of April is going to feature Top 5 record cold. I don't see it happening. April is going to finish with at least a mean temperature of 57. I mean, 2023 ended at 57.6, and that last part of April was really cold. Warmer than normal April should be locked at 100% at this point.

This time of year it’s only a matter of when and how much we’re paying for a summer like stretch like this. 

I am curious to see how much rain we actually get vs just low clouds and onshore flow.

If the trough is east of us, probably not much which isn’t good either since many of us are back in a drought. 

We are seeing elements of the spring 2023 pattern with how early and strongly this El Niño is developing. That year had a shift to stronger blocking in late April following early record 90 warmth. Notice the 2 matching dates from 2023 and how close in time the record warmth was. 

So it’s possible that this week will turn out to be the warmest we see for a while. But rainfall has been generally disappointing. Maybe the developing STJ can allow for some better rainfall opportunities especially by the early summer like we saw in 2023.

Personally, I think the modeling may be somewhat too cool for the second half of April, but the ECMWF weeklies show cooler than normal conditions for the April 20-30 period. In addition, a  strong cold shot lies ahead for early next week. One or two days will likely to see readings approach or reach 10° below normal. Outside NYC, some areas could experience a late-season freeze.

In mathematical terms, one would not need near record cold to reach the figure from the guidance (overnight the guidance ticked up a few tenths of a degree).  If one took all the readings to date and assumed that the remainder of the month would average normal, one would come up with a 56.6° mean. Normal for April 17-30 is 56.8°. Since 2020, five years have had a cooler April 17-30.

As for 2023, April 1-16 had a mean temperature of 59.9°. That was much warmer than April 1-16, 2026. This year's mean temperature was 56.4°. 

Finally, the probability is based on a normal distribution. Part of the region under the curve is still below normal at this point in time based on the standard deviation. Although I would be quite shocked were April to wind up cooler than normal overall, that doesn't mean that a statistical probability of such an outcome doesn't exist, even if it's low. The stated probability means that a warmer than normal April is very likely.

75 / 57 clouds to the north.  Step down to upper 70s / low 80s with enough sun, possibly a bit warmer if mostly sunny in the warm spot. Perhaps a n isolated shower later today.  Saturday looks great back towards normal , Sunday front comes through with best shot at any rain.  Overall cooler than normal week - contingent on extent of onshore backing in and clouds could be near normal and a few nice days away from the onshore or pure / typical marine layer cool.  Still looking mainly dry but these have a habit of rain popping on a several days.

4/17 :   Warm
4/18 - 4/19 :  Near normal
4/20 - 4/21 :   Chill down 
4/22 - 4/28 :  Near - below normal perhaps wetter.
4/29 - beyond :  moderation towards the end of the month / early May

Historical:


1821: The Massachusetts’ legislature could not open due to 18 inches of snow. (Ref. Wilson Wx. History)

1875: The minimum temperature for the date is 26°F in Washington DC. (Ref. Washington Weather Records - KDCA)

1920: Snow fell across Denver, CO continuously for 57 hours; from early morning on the 17th until midday on the 19th. The heavy wet snow totaled 18.2 inches with the greatest accumulation on the ground of a foot. At times winds gusted to near 50 mph creating near blizzard conditions. The strong winds created high drifts halting auto and rail traffic. Many people were stranded. No lives were lost in Denver but several people perished in surrounding districts. Temperatures didn't make it out of the 20s. (Ref. Wilson Wx. History)

1922 — A family of at least six tornadoes caused death and destruction along parts of a 210 mile path from north of Ogden IL to Allen County OH, killing sixteen persons. A post card, picked up in Madison County IN, was found 124 miles away near Mount Cory OH. (The Weather Channel)

1942: West Palm Beach, FL was soaked by 8.35 inches of rain in just two hours. (Ref. Wilson Wx. History)

1953 — One of the few severe hailstorms accompanied by snow, sleet, glaze, and rain, pelted parts of Kay, Osage, Creek, Tulsa, Washington, and Rogers Counties in northeastern Oklahoma late in the day. Nearly 10,000 insurance claims were filed. (The Weather Channel)

1965 — The Mississippi River reached a flood crest at Saint Paul MN four feet higher than any previous mark. During the next two weeks record levels were reached along the Mississippi between Saint Paul and Hannibal MO. Flooding caused more than 100 million dollars damage, but timely warnings kept the death toll down to just twelve persons. (David Ludlum)

1970: After 10 p.m. near Cotton Center, TX, an F4 tornado “smashed flat as a pancake” a pickup; 2 people killed. Up to 6 blocks wide, it later hurt 40, caused $4.5 million damage in Plainview. It was hidden from view by fog, lack of lightning, and little accompanying noise. (Ref. Weather Guide Calendar with Phenomenal Weather Events 2011 Accord Pub. 2010, USA)

1983: Burlington, VT picked up 15.6 inches of snow to set an April record. (Ref. Wilson Wx. History)

1984: A spring storm left snow across much of the central portion of Iowa. The greatest concentration of snow was in an 80-mile wide band from Monona County southeast to Des Moines and Knoxville. Four to six inches were common in this band but the greatest amount of 8 inches occurred in Des Moines. Temperatures hovering near the freezing mark prevented large accumulations on the road. (Ref. Wilson Wx. History)

1987 — Twenty-two cities in the central U.S. reported new record high temperatures for the date. Temperatures warmed into the 70s and 80s from the High Plains Region to the Mississippi Valley, with readings in the low 90s reported in the Southern Plains Region. Tulsa OK hit 92 degrees. (The National Weather Summary)

1988 — Heavy snow blanketed northern Arizona. Snowfall totals ranged up to 16 inches at Pinetop, with 10 inches reported at Flagstaff. Afternoon thunderstorms spawned a couple of tornadoes in Idaho. (The National Weather Summary) (Storm Data)

1989 — Arctic cold invaded the north central U.S. Missoula MT was blanketed with four inches of snow, and Glasgow MT reported a record cold morning low of 14 degrees above zero. (Storm Data) (The National Weather Summary)

1990 — High winds in northern Utah, gusting to 90 mph in Weber County, blew a trampoline through a living room window, and strong winds associated with a cold front crossing the Middle Atlantic Coast Region gusted to 75 mph in the Chesapeake Bay area of Virginia. Unseasonably cold weather prevailed in the north central U.S. Valentine NE was the cold spot in the nation with a record low of 10 degrees. (The National Weather Summary) (Storm Data)

1994: Record Alaska cold -39°F in Umiat, -32°F in Prudhoe Bay are the coldest ever for so late in the year; +2° in Fairbanks is the coldest so late since 1972. (Bob Ryan's 2000 Almanac)

2002: The heat wave continued across the east as high pressure off the Carolina blocked a frontal boundary across the Plains. Records for the date included: Newark, NJ: 97°, NYC Central Park: 96°, Hartford, CT: 95°, Philadelphia, PA: 95°, Reagan National Airport, DC: 95 (Tied monthly high), Lynchburg, VA: 94°, Atlantic City, NJ: 94, Islip, NY: 94°, Concord, NH: 94°, Norfolk, VA: 93°, Dulles Airport, VA: 93° (April Record), Baltimore (BWI), MD: 93°, Providence, RI: 93°, Boston, MA: 93°, Salisbury, MD: 92°, Wallops Island, VA: 91°, Harrisburg, VA: 91°, Williamsport, PA: 91°, Albany, NY: 91°, Worcester, MA: 90°, Burlington, VT: 90°, Syracuse, NY: 89°, Bridgeport, CT: 89°, Binghamton, NY: 86° and Portland, ME: 80°.

Picked up .06" rainfall with a quick moving t-shower around 10:00 last evening.  Places west and NW of here did better with greater than .25".  We'll see how much we can add on Sunday.  Heat was nice but a bit much for mid April.  Looking forward to a cool down but could do without the cold mornings upcoming early next week.  On the other hand will be nice to sleep with the windows cracked open again.

Nothing from last night to my knowledge.
The Tuesday night line went all around me with a gap over Sparta.  I only recorded a trace.
 

Meanwhile, western PA and up through Buffalo, Finger Lakes and the upstate is having it's third night in row of a pretty solid line of storms.  No rain issues there.

You should have done pretty good last night right?

65+ is humid IMO.  My DP is 53 in Muttontown/62 in Syosset (always high DP) and winds are Northerly component all over the place.

Yea i mean FRG is 61, the closest airport. Wind just shifted north about 15 min ago. 

Also, Gemini doesn't lie

A dew point of 60°F–65°F (16°C–18°C) is typically when air begins to feel "sticky" or humid. When dew points reach 65°F–70°F (

I'd also say it depends on the time of year. Low 60 DPs in April is pretty muggy. Mid-summer, it's refreshing.
