7-27-18.....3.00" so far at the Staten Island mesonet. http://www.nysmesonet.org/mesonow#?stid=STAT 1 day:3.00″

Parts of the area had around 60" of snow in just over 30 days. Can you imagine if that snow machine continued through February or even March?

Boxing Day in 2010 was our last major KU in December. Much more backloading to the winters since then. December 2000 to 2010 was unsurpassed with so many major early season events in an 11 year period.

Near the castle along the 79th st transverse through Central Park. The last photos on the site below were taken in 2013. So you are looking at 5 years of growth on top of that. http://www.weather2000.com/ASOS/NYC_ASOS.html

The old rule living in Long Beach was to never park under a sycamore. Those trees were in really bad shape even before Sandy. Many of them had large sections that were bare. Even a strong sea breeze would cause small branches to break off on parked cars. The city fell behind in the tree maintenance in the years before Sandy. But all the saltwater root damage was the final straw for most of them to get cut down. Long Beach still doesn't look the same to me with all the open space where the large trees used to be.

Enhanced clean up this week for the local landscape specialists. The trees seemed to drop more leaves than usual with the weekend storm following the recent drought stress. There is also quite a bit of bark and broken small branches lying around. A few large bird nests also blew out of the trees.

Another measure of how strong the reverse dipole is this summer. Yesterday's high of 5.2°C in #Iqaluit, Nunavut is coldest on record for July 17. Previous was 5.4°C in 1978. Records kept since 1946. #NUwx #Nunavut #North 5:28 AM - 18 Jul 2018 Alert, Nunavut hit 10°C for the first time of the year yesterday, 2 weeks later than normal (1981-2010). #Arctic #North #Nunavut 5:36 AM - 18 Jul 2018 Yesterday's high of 0.9°C in Resolute, Nunavut is coldest on record for July 21, beating 1.1°C in 1954. Records kept since 1948. #Nunavut #NUwx #Arctic 6:37 AM - 22 Jul 2018

The proposed system will have gates from Sandy Hook to Breezy point and near the Throgs Neck bridge. So it will prevent a surge from the LI Sound and Atlantic. You know systems like this will become a reality in the future with rising sea levels. Remember, they were talking about protective dune systems for LB since the 1980's and 1990's. It finally took Sandy to get the ball rolling on the project. So my guess is that systems like this will start to get built sometime between 2025 and 2050. https://en.wikipedia.org/wiki/New_York_Harbor_Storm-Surge_Barrier

The bays along the South Shore need to be included in some version of this. https://www.wnyc.org/story/army-corps-proposes-giant-hurricane-barrier-across-new-york-bay/ More than five years after Sandy, the U.S. Army Corps of Engineers is taking a closer look at one of the ideas that caught the public's imagination right after the storm hit: a giant steel-and-concrete barrier that would stretch across New York Harbor and prevent an ocean surge from flooding waterfront areas again. Such barriers gained prominence in the Netherlands, where a series of structures called the Delta Works protects the southwestern part of the country. But they're also in use in London; St. Petersburg, Russia; Providence, R.I.; and Stamford, Conn. The gates are kept open most of the time to permit ships to pass and water to circulate, but they swing closed when a hurricane approaches. (The gates in Stamford swing upward off the sea floor.)

That recent study is a bit of an outlier. http://www.realclimate.org/index.php/archives/2018/07/does-a-slow-amoc-increase-the-rate-of-global-warming/#more-21540

The Arctic circulation pattern since May has been the complete opposite of 2012.

The 2010's just keep producing one new extreme after the other. https://www.washingtonpost.com/news/capital-weather-gang/wp/2018/07/17/extraordinary-record-rainfall-drenches-reagan-national-airport-2-63-inches-in-42-minutes/?utm_term=.f7a62d249b62 There had been no measurable rain at Reagan National Airport, Washington’s official weather site, in 19 days, including none in the first 16 days of July, a record. Then, in 42 minutes, the heavens unloaded 2.63 inches as intense thunderstorms barreled through the region. “I’ve been here 40 years,” said airport observer Nicholas Parrell. “I’ve never had that.” In all, 2.79 inches fell in just over an hour, setting a record for July 17 and besting the 2.05 inches from 1945. It was the airport’s biggest single-day rainfall in almost a year (since July 28, 2017) and the second-most for a July day since 1975. “That certainly is a very heavy amount for a short period of time,” said Chris Strong, warning coordination meteorologist at the National Weather Service office in Sterling, Va., in an email. In the afternoon, 0.95 inches of rain fell in just nine minutes and 1.22 inches fell in 15 minutes. Such rainfall intensities are expected only once every 10 to 50 years on average.

Some people actually shot a video from Maple Blvd right next to the Lido Towers during Sandy. You can see how fast the current was moving without much of a dune to slow things down. The President Streets neighborhood just to the west was about a foot higher which helped save a number of houses from flooding inside.

Hard to believe that some residents still can't agree on letting the Army Corps do their stretch of beach. Army Corps not allowed to work at private condo http://liherald.com/wantagh/stories/concerns-over-beach-project-in-lido,105089

They did a few spots along the LI South Shore over the years. But nothing as extensive as this current project. The new jetties already give the beach a different look. I may not recognize the place once the new dunes and walkovers are in place. As it is, parts of Long Beach look much different due to many of the sycamores which were cut down after Sandy.

Pretty cool watching the sand dredging videos from Long Beach. They are starting out in the West End. https://patch.com/new-york/longbeach/dredging-officially-underway-long-beach-shore

Looks like the CAB may have set a daily record low temperature with the impressive reverse dipole pattern. http://sites.uci.edu/zlabe/arctic-temperatures/

These big swings in either precipitation or temperature just won't let up. https://www.washingtonpost.com/news/capital-weather-gang/wp/2018/07/12/washington-is-in-a-flash-drought-with-only-fleeting-chances-of-rain-in-the-forecast/?utm_term=.992ff1e3e945 Remember May and June, and all of the torrential rain? Ellicott City catastrophically flooding for the second time in two years, and Frederick overflowing with water? That is absolutely over now. Seemingly overnight, two months of often-unfathomable rainfall ceded to sunny, hot days and parched lawns. Since June 27, the last day of rain, Washington has received zero measurable precipitation, as measured at Reagan National Airport. That’s 14 days in a row, and it’s really strange — especially since the season that’s supposed to deliver afternoon showers and thunderstorms like clockwork is not yet over. “This stretch we are in now is about as dry as it gets this time of year” in Washington, according to Ian Livingston, our local climate guru. He’s specifically taking into account the fact that we’re still in the peak of summer thunderstorm season. Going beyond “strange” and getting a little more technical, Washington is in a “flash drought” — a short period of high temperatures and rapidly decreasing soil moisture. There are two kinds of flash droughts: those caused by heat waves and the ones caused by lack of rainfall.

Lowest surface loss in decades for June. The record late snowpack prevented the local shorebirds from nesting this season. after months of a persistent atmospheric circulation pattern, Greenland is having its least surface ice loss in decades while NW Europe has extreme sun and heat... persistent extremes are an expected signature of #climatechange@PolarPortal #ukheatwave twitter.com/severeweatherE…pic.twitter.com/lsXraH5nuK 6:16 AM - 3 Jul 2018 But Churchill Falls (Labrador) saw its coldest June by a 2C margin; the monthly temperature was 6C below normal. Persistent major circulation anomalies are to blame. pic.twitter.com/Iz5QPeXuBr 8:43 AM - 3 Jul 2018 https://www.scientificamerican.com/article/late-snowpack-signals-a-lost-summer-for-greenlands-shorebirds/ Millions of shorebirds descend on the Arctic each year to mate and raise chicks during the tundra’s brief burst of summer. But that burst, which usually begins in mid-June, never arrived this year for eastern Greenland’s shorebirds, a set of ground-nesting species. Instead, a record late snowpack—lingering into July—sealed the birds off from food and nesting sites. Without these key resources avian migrants to the region will not reproduce in 2018, experts say.

ISP had 1.91" on 8-18-17 with the 2"+ amounts closer to the North Shore.

Hard to believe the 2014 deluge was the last summer event at ISP over 2.00". 8-13-14.....13.51 6-8-13......4.58 7-29-12....2.99 6-25-12....4.16 6-13-12....2.32 8-28-11....3.03 8-15-11....6.49

Yeah, 2007 to 2012 was a truly historic period for the Arctic. Some people may not appreciate the rarity of locking in that dipole patttern for 6 seasons in a row. https://onlinelibrary.wiley.com/doi/pdf/10.1029/2012GL053268 Thus we can say that a six year run of near one standard deviation negative excursions (2007–2012) is unique in the 63 year record. To further test the significance of the 2007–2012 AD patterns we randomly generated 10,000 time series, each with 63 points to match the observed time series and with a normal distribution without autocorrelation. For this simple calculation, the chance for having five consecutive values with a negative AD of magnitude greater than 1.0 standard deviation units in a sample size of 63 is rare, less than 1 in a 1000. Yeah, it seems like the SPG region cooling south of Greenland since 2012 is the result of an atmospheric circulation change to more low pressure. SST’s in that region we’re near record levels of warmth prior to the abrupt circulation shift leading into the 2013 summer. Maybe there is some mechanism by which salinity changes following the 2007-2012 record melt can lead atmospheric circulation shifts by months or years?

The NAO averaged for May and June was the most positive on record. This is in stark contrast to the 2012 season which had the 2nd lowest on record.
