May 2026

[SACRUS]

56 / 42 NE flow - cool , cloudy showers.  What should tally up to 4 more days of mainly clouds with the brunt of the >1.00 - 2.00 inches of rain saturday night into Sunday night.  Pokes of some sun Monday and Tuesday but slow to clear out.  Much nicer Wed - Thu low 80s.   Next cut off backs down and in between Fri and through next weekend and id wager it trends unsettled as ridge balloons into candada.  Ridge finally expands east 6/3 - beyond pushing above normal overall.

And of course I was heading to Yankee stadium with my son and a couple of friends.

Game cancelled.


.

Who determines if a game is postponed ? The home team or MLB ? Obviously  a decision favoring the Yankees because Tampa Bay is in first and HOT and the Yanks are NOT !

Trying to predict rainfall amounts in this set up is next to impossible IMO. Models don't have a handle on exactly where the heavier precip will occur. More than likely there will be a wide range of amounts spread throughout the region IMO.

I agree. This is a very challenging setup.

In winter we have virga when radar shows snow but nothings falling.  What do we have when radar shows moderate rain but nothings falling?

Can you expand these to 3 days (Saturday, Sunday, and Monday), so I can see the whole picture for the entire Memorial Day weekends? For example, 2021 at 72 and 0.00 rain looks misleading because you had highs in the 50s (probably record low maxes) and a lot of rain on Saturday and Sunday.

[SnoSki14]

53F right now. Chilly with the breeze

[winterwx21]

53 degrees with steady light rain. Nasty.

you have to be exposed to a virus to catch a cold.   Cold weather has no bearing.

[Brian5671]

Been raining lightly since 9am here.  53 degrees

[uofmiami]

Interesting stat

 

[CPcantmeasuresnow]

49° with light rain. I'll take it over the 90° a couple of days ago.

[eco94]

Why is it literally not raining and when is that going to change- Long Beach

[psv88]

Rain all day here. Went down to the boat and it’s not too bad hanging under the canvas

I'd be curious to see the Saturdays and Sundays in here too. I particularly remeber a recent Memorial Day weekend maybe 5-7 years ago, my oldest son played golf on a Saturday in the rain with temperatures in the low 40's during the afternoon. Similar to today but 5-7 degrees colder.

This weather sux  I turned the heat back on AND lit a fire in the fireplace. Fukn late May...

NYC Central Park Memorial Day Climatology (1920–2025)

106 Years of Historical Memorial Day Weather Analysis

Over a century of Memorial Day weather observations reveals that many assumptions about the holiday do not match reality. While people often remember either extreme heat or complete washouts, the long-term record tells a more nuanced story involving dry-weather regimes, clustered extremes, and noticeable warming signals.

Top 15 Findings

1. The "average" Memorial Day is milder than most people remember
Across 106 years, the average Memorial Day high was 75.5°F, with an average low of 57.5°F. Memorial Day in New York is historically more late spring than full summer.

2. Memorial Day is dry much more often than wet
Rain occurred in only 32 of 106 years (30%), meaning roughly 7 out of every 10 Memorial Days were dry.

3. Weather memory is biased toward extremes
People tend to remember either 90° BBQ days or holiday washouts. Most years are actually moderate and comfortable.

4. The hottest Memorial Day reached 92°F
The warmest Memorial Day occurred in 1942, reaching 92°F.

5. The coldest Memorial Day reached only 55°F
The coolest Memorial Day high occurred in 1974, a full 37°F colder than the warmest year.

6. Memorial Day weather has surprisingly high variability
A 37°F spread between the warmest and coolest Memorial Days shows how dramatically conditions can vary despite being the same holiday.

7. Rainfall follows a "feast or famine" pattern
Average rainfall was only 0.14 inches, while the wettest year received 2.49 inches, nearly 18 times the average amount.

8. A handful of years dominate rainfall totals

Largest Memorial Day rainfall events:

1948: 2.49"

2016: 1.65"

2003: 1.28"

2024: 0.96"

1993: 0.90"

A small number of years contribute disproportionately to total Memorial Day rainfall.

9. The 1934–1947 Memorial Day dry stretch stands out as one of the strongest signals in the entire record
Between 1934–1947, Memorial Day recorded no measurable rainfall across fourteen consecutive holidays. Using the long-term climatology where roughly 70% of Memorial Days are dry, this is statistically unusual and likely reflects a broader climate regime rather than simple random variation.

10. The early 2010s stand out as a warm cluster
Between approximately 2010–2015, multiple Memorial Days reached the mid to upper 80s, creating one of the warmest clusters in the record.

11. Overnight temperatures may be warming faster than daytime highs
The warmest Memorial Day low was 71°F (2012) while the coolest was 44°F (1992). This can be an indicator of changing urban and climate conditions.

12. Holiday timing changed in 1971
Before 1971, Memorial Day occurred every May 30. Beginning in 1971 it shifted to the last Monday in May, introducing a slight climate timing effect.

13. Memorial Day weather appears to occur in regimes rather than random year-to-year noise
The record contains visible clusters of:

Warm periods

Cool periods

Dry periods

Wet periods

 

14. The strongest climate signal may be persistence
Instead of isolated years behaving independently, weather patterns appear to sustain themselves over multiple years.

15. The "typical" Memorial Day still wins
Despite extreme years receiving the attention, the long-term average remains remarkably stable: mid-70s during the day, upper-50s at night, and dry most of the time.

Brutal today.

Nothing like a 50 degree swing in a few days.  

I hope JJA turns around and we get some consistent heat.
