I compiled a list of the 3"+ heavy rain events in the OKX forecast zones since 2010. Feel free to include any of your local events that I may have missed. The dates below are when the rainfall event ended at each location. 2018 4-16.....EWR...3.43....NYC....3.29 3-2.......ISP....3.35 2017 10-30....EWR...4.08...NYC...3.28...JFK...3.20...BDR...3.02...ISP....4.02 10-25....BDR....3.78 8-18......East Shoreham....3.80 5-6.......EWR....3.15....NYC...3.20 2016 11-30...EWR...3.09...LGA....3.19 8-2.......New Suffolk....3.00 to 4.00 2015 9-10....Wantagh...6.05 6-1.....EWR..........5.39 2014 12-10....JFK...3.15 8-13.....JFK...3.26....ISP....13.51 5-1......EWR...5.31....NYC...5.09....LGA...5.41....JFK....4.92...BDR...3.99 3-30....JFK...3.13.....BDR....3.20....ISP....3.86 2013 6-8....EWR...3.89...NYC...4.64.....LGA...4.12....JFK...4.39....BDR...4.54...ISP....4.58....Old Bethpage...6.13 5-9....NYC....3.52 2012 6-25...ISP...4.16 4-23...Lynbrook....3.49 2011 9-7.....EWR...4.27...NYC...4.43...LGA....3.32 8-28...EWR...8.92...NYC...6.87...LGA....5.78....JFK....5.03....BDR...3.35....ISP...3.03 8-15...EWR...6.56...NYC...6.37...LGA...6.64...JFK....7.80...BDR....3.17....ISP...6.49....Lido Beach....10.20 5-18...BDR....3.61 2010 10-01...EWR...3.57...NYC...3.56...LGA...3.06...JFK...3.08... 3-30....EWR...3.15....NYC...4.03...LGA...3.87....JFK...4.37...BDR...3.54...ISP...4.82 3-14....EWR...4.57....NYC...4.10...LGA...3.33....BDR...3.70

Luckily, none of the dry summer months of the 2010's came close to 1999 and 1995. That was the last time any of our major stations experienced less than .50 during a summer month. I can still remember some of the local ponds almost completely drying up. Since then, brown lawns were the greatest effect of the lesser dry patterns. EWR....Jun 99......0.41 NYC.....Jul 99......0.44......Aug 95.....0.18 JFK......Aug 95.....0.22 LGA.....Aug 95.....0.12

Big change following the late 2002 through 2011 historic wet period.

We had the beach version in Long Beach last summer. The interesting South Shore sighting this week was the Thresher shark coming into the bay north of Jones Beach. https://patch.com/new-york/longbeach/dust-devil-touches-down-long-beach-whisks-away-beach-gear

One of the more bizarre weather videos of the year.

Models also speeded up the frontal passage for Tuesday so it comes through drier with less instability.

Yeah, the second half of June will easily be warmer than the first half was. Dueling ridge pattern between the East and West Coasts. Ridges are popping right where all the warm SST departures are located.

Odd contrast between near record lowest tornado activity in the US and mini Tornado Alley in the Northeast during May and June. http://www.spc.noaa.gov/wcm/adj.html

The strong offshore flow really dropped the humidity today. Made it pretty easy for temps to beat guidance. Newark/Liberty FAIR 87 45 23 NW21G32 29.75S

Unusually cold weather near the Beaufort region for a change with the strong TPV. This is actually the coldest departures around that region over the last year. My guess is that this impressive June TPV behavior will keep the 2012 record out of reach again for this season. From the Alaska Weather Blog: http://ak-wx.blogspot.com/2018/06/chilling-in-summer.html Northern and interior Alaska has seen some very chilly weather for the time of year in the past few days, as a strong upper-level trough and an unseasonably cold air mass plunged south out of the Arctic at the beginning of the week. Despite the fact that the summer solstice is now less than 10 days away, and daylight is continuous, sub-freezing temperatures have occurred in many of the usual cold spots in the interior. The airport has seen 37°F, 36°F, and 37°F in the early mornings of the past three days, which is a remarkably cold series of daily minimum temperatures for this time of year. In fact, this is the closest to the solstice that Fairbanks has ever observed 3 straight days with low temperatures of 37°F or lower at the official climate site (1930-present). It's also interesting to note that with a high temperature of only 53°F, Monday's daily mean temperature was a mere 45°F. It's been almost 70 years (1949) since Fairbanks saw such a chilly day this late in June (or in July).

Conditions are starting to dry out this month around the area. The surge of 850's near +20C early next week should continue this process.

Yeah, July 1999 was also the warmest for ISP. The 2010's have the most years with 80 degree Julys at our local stations. No other decade has had 5 years. 80 degree Julys 1908...1952/1955...1966....1988....1993/1994/1999....2002/2006/2008....2010/2011/2012/2013/2016

The new definition of a cool July in the 2010's is one that averages below 80 degrees at both EWR and LGA. At least one station reaching 80 bolded 2010...EWR...82.3....LGA......82.8 2011...EWR...82.7....LGA......80.4 2012...EWR...80.8....LGA......80.4 2013...EWR...80.9....LGA......81.2 2014...EWR...77.0....LGA.....77.0 2015...EWR...79.0....LGA.....79.2 2016...EWR...79.9....LGA.....81.1 2017...EWR...77.3....LGA.....78.1

I believe July 2013 was our last one in the East. Maybe at some point in the future we push 604.

Yeah, the ridge pulses back down just a few days later as heights really rise near the PACNW. So it looks like a 2-3 day event. Imagine if we ever got a summer ridge that went as extreme as we saw back in February or December 2015. That would probably be our first summer month in the +6 to +10 range. I guess we would have to see a 2013 mid-July WAR like lock in for an entire month.
