Rain is not done yet…

The main event was over, but yeah added .23 more here from the late night showers. Heard some pinging on the window when I was trying to get to sleep, so we had a little sleet mixed in with the rain. Was quite an event with a t-storm and a little wintry precip at the end. 3.08" was the 3 day rain total here.

Not surprised, two weeks ago I posted a sustained warm pattern would wait until mid April. Hope that doesn’t get pushed off further, as this isn’t great spring weather currently. 

We have had a generally warmer minimum temperature pattern over the last two weeks. But all the clouds, onshore flow, and rain have been keeping the maximums down.

1 NNW Crown Heights in Brooklyn had sustained winds of 49 mph yesterday. Numerous locations reported sustained winds of 40 mph or above in the New York City area and suburbs.

[jm1220]

Bayville and Eatons Neck both had 68mph gusts. They’re windy spots in any easterly wind events but no doubt the HWW verified. Also looks like numerous large branches/some trees down around the island. Rain generally 2.5-3”.

The statistical predictors based on record SSTs and La Niña are very impressive for the coming hurricane season.

A very dangerous picture is getting painted for this upcoming Atlantic hurricane season. All the indicators right now are pointing to a record breaking season and have been since March….

Based on what I am seeing right now, we at least have a shot at one month from June through October with very excessive rainfall over 10.00”. That would be a scenario with hurricanes or tropical storms making landfall to our south and then tracking north. If we can string together more than one month of excessive rainfall, then  the flood threat would be even higher. The worst scenario would be a direct hit which would add the damaging wind and coastal impacts. So we’ll have to monitor the coming season actual storm tracks very closely. It’s even potentially more problematic based on all  the record rainfall since last summer.

The key will be how many landfalling storms-some big nina years have alot of fish storms...

We had an insane cell come through last night that must've dropped darn near an inch or more itself!

Need to get my weather station setup at the new house in Monroe.

Hopefully if the big ACE season pans out there are lots of recurves. In a Nina it’s our one positive indicator for a snowy winter we can look forward to. But the tendency for the Bermuda high ridge to spike further north the last 5 summers or so might also mean storms are headed N at our latitude not NE which is a big danger if we have hurricanes near the Carolina coast.

I'm in Florida, so that was from my station which i can see from my app.  But I saw a cocorahs near me with 3.6" as well.

While not able to break NYC daily rainfall record on April 3 (1.90" 1983), the 48h total of 2.42" (0.87"+1.55") does set a new high for April 2-3, previously it was 2.01" in 1917.

Today, both records are 1987 (1.99" one day, and 2.48" 2d for April 3-4). 

I posted all such records on page 13 of this thread (and I edited in 2024). 

Current pattern cannot be a lot different fro 1915 with its record 10.0" snowfall (on April 3), and worth noting that April 25 and 27 of 1915 both set records in the low 90s. The only other part of 1915 that was particularly warm was mid-September.

 Today’s NAO is -2.00, which is the most negative of any day Feb 15th through April 7th for the years 1950-present. The old record for that period was -1.84. Also, there have been record daily -NAOs the last five days:

For the Delaware River Basin we haven't had a true drought since 2002. By true drought I mean from a hydrological standpoint. The last drought warning / emergency ended in NOV 2002. The highest weekly drought severity indexes for the NE back to 12/2000 were during the 2002 drought peaking on 3/12/2002 with an index of 228. For a frame of reference the fall 2016 dry period peaked at 161, fall 2020 at 131 & the summer 2023 dry period topped off at 107.

Since 2002 dry periods have been rare & when they happen they don't have a long shelf life.

yeah the drought I'm refering to in summer 2022 was more of a "flash drought"  bone dry for about 3 months before the wet pattern returned-it was very dry though-lawns was toast and even some leaves on trees died...we had something like a half inch of rain in July which combined with the strong sun really dried things out

It’s hard to believe that the last true drought emergency we had in the metro area was over 22 years ago (2002). The drought/wet cycles don’t normally run this long

I remember it, I recorded 5.34" for June, July, August which honestly is more than I would've thought with how dry everything was in July and August 2022.  Lately we get 5" every couple of weeks.

Thanks! I'll certainly have the station setup by then.

I've bounced around this whole darn state. Born and a few years in Hillsborough. Moved and grew up in Raritan Township (was there for 96). Then to East Amwell (where I spent most of my childhood and teen years and where my heart will always be). Then to Flemington. Then once I met my now wife we moved up to Phillipsburg (the arctic). Then to Howell for a few years when we started our family. Now we've settled in Monroe and the thought of any more moving makes me ill hah! All those moves and haven't gotten out of NJ.

Not entirely upset though, it's an amazing state.

A snowstorm is raging in parts of northern New England. Snowfall amounts include:

Bangor: 8.1" (old record: 6.0", 2007)
Burlington: 8.8" (old record: 2.7", 2004)
Concord: 6.7"
Portland: 6.4" (tied record set in 1915)
Worcester: 5.5"

Following the damaging storm that brought sustained winds as high as 49 mph to the New York City area, sunshine returned and the temperature rose into the 50s.

The next few days will feature readings in the 50s. After a cool first week of April, it will likely turn noticeably warmer during the second week of the month.

New York City's Central Park remains on track to finish the 2023-2024 snow season with less than 10" of seasonal snowfall for a record second consecutive season. Records go back to 1869.

The ENSO Region 1+2 anomaly was -0.4°C and the Region 3.4 anomaly was +1.0°C for the week centered around March 27. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +0.42°C and the ENSO Region 3.4 anomaly has averaged +1.27°C. The ongoing basinwide El Niño event is fading. Neutral conditions could develop later in the spring.

The SOI was -12.19 today.

The preliminary Arctic Oscillation (AO) was +0.161 today.
