The strongest part of those storms missed just to my north last night. Nice downpour with some wind gusts into the 30’s. Pattern change to less warmth and humidity right on track. This should last into the first week of September with 2 big Canadian highs rolling across SE Canada and New England.

It'll finally be bearable to spend the weekend outside. 

First sign that autumn draws closer.

What a difference a year makes. Complete opposite of the major heatwave from late last August into early September. The big heat this summer was focused into July with high humidity lasting well into August.

I thought today was supposed to be rain free? I guess my plans to PT Pleasant will be cancelled. 

 You can't catch a break with this rainy weather. Sorry to hear your trip to Wildwood was ruined. I'll be heading down there the day after Labor Day for a few days. Hopefully the weather will hold up.

My gf and I still did plenty of stuff down there but I wish the weather was nice. 

 

It's her last week before she has to set up for the school year.

To even get marginal success in the garden this year has meant an awful lot of time spent. Even with the attention the yields have been anything but good.

I saw you mentioned the guy in CT in another post. Putnam County where I live has had the cyano issue for a while now and a few other wonderful things too. In 2018 we had 46% of all lake beach closures in NY State. This year has been a little bit better but not much. One of the big reservoirs has turned this putrid color over the last year or so, stayed that way even through the winter. I don't trust any open fresh water around here anymore.

 

Yay it's raining! I'm up to .1" :rolleyes: The heavy stuff slid just south of me, missed by maybe 2 miles. 

I've heard that pets are dying from drinking pond water or even just swimming in it.  :(  PS the tap water here isn't healthy to drink anymore.  I made the mistake of doing that earlier in the summer and I was immediately suffering from horrible cramps.  Tried it again last week, same result.  The pain was so intense that I was bent over while running to the bathroom both times.

It happened to me last summer too.  Not going to drink tap water anymore during the summer.

Looks like the wind forcing open a garage door caused the back wall to blow out in Farmingdale. Good thing nobody was in those parked cars.

 

Chris how much wind is required to do this much damage?  Was it a microburst?  That 60 mph report doesn't seem to be enough- you didn't see stuff like this even in Sandy.  I estimate the wind must have been 100 mph.

And these are pics of my sister's house after the microburst I told you about.  How strong could the winds have been there to do this?

Even if we do not have another heat wave, Europe is about to have its third this year.   Heights at +240m---good for +20F or more above normal for some.

whats causing most of the heat to be on that side of the globe this year? could London and Paris hit 100+ again?

Cooler weather has now overspread the region. This cooler weather will likely last into early next week.

In western North America, much above normal temperatures could develop in the Pacific Northwest and western Canada during the middle and latter part of next week.

Across the Atlantic Ocean, this weekend will see the start of an extended period of above to much above normal temperatures in Europe. Record temperatures will likely be challenged and broken in many locations. This latest round of heat could last through the upcoming week.

Anchorage is nearing the end of its warmest summer on record. Based on sensitivity analysis applied to the latest guidance, Anchorage will finish summer 2019 with a mean temperature near 62.6°. The summer record is 60.8°, which was set in 2016.

In addition, Anchorage will likely set a new August record high mean temperature. The implied probability for its warmest August on record is 70%. That would be the third consecutive monthly record set this year. No single year holds three consecutive monthly records (cold or warm), much less during the same season, in Anchorage.

The ENSO Region 1+2 anomaly was -0.7°C and the Region 3.4 anomaly was +0.1°C for the week centered around August 14. 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 +0.33°C. Neutral-warm ENSO conditions are in place in Region 3.4 with neutral-cool conditions in place in Region 1+2. There is considerable uncertainty about the ENSO evolution later this summer into the fall. Some of the guidance continues to show the development of neutral-cool ENSO conditions.

The SOI was 4.19 today.

Today, the preliminary Arctic Oscillation (AO) figure was -0.526. A general tendency for blocking could persist through the remainder of August with perhaps some fluctuations to positive values.

The AO has averaged -1.062 for August. Since 1950, there have been five prior cases when the AO averaged -0.500 or below in both July and August: 1950, 1958, 1960, 1968, and 2015. The average temperature for September was 69.1° (69.8° after adjusting for ongoing warming) and 58.9° (59.6° adjusted) for September through November in New York City. The 1981-2010 baseline normal figures are 68.0° and 57.5° respectively. The majority of cases saw a warmer than normal September and all cases featured a warmer than normal fall. Therefore, a warmer than normal September and fall appear likely. The potential for autumn 2019 to rank among the 30 warmest cases on record is on the table.

The MJO's recent high-amplitude passage through Phase 4 during the August 5-15 period has been followed by a range of solutions in the September 1-15 period during past cases. The coolest was 2001 with a mean temperature of 70.7° in New York City. The warmest was 1983 with a mean temperature of 77.2° in New York City. The 1981-2010 base normal for the September 1-15 period is 71.8°. Right now, with 1993 remaining the baseline case, a plausible outcome could see a few cooler than normal to near normal days during the first week of September followed by warming that would result in a warmer than normal September 1-15 average temperature.

On August 22, the MJO was in Phase 2 at an amplitude of 1.123 (RMM). The August 21-adjusted amplitude was 1.106.

Finally, New York City has an implied 61% probability of having a warmer than normal August. The implied probabilities for New York City's receiving 50.00" or more precipitation this year are 70% (historical 1869-2018 period) and 80% (1971-2018 period). The least precipitation from August 24-December 31 occurred in 1931 when just 7.65" was recorded. The most was 32.57" in 1983.

While this was another very humid August, it’s turning out to be much cooler than last year. So this summer will go into the books as a continuation of the high dewpoint regime since 2016.
