June 2020 General Discussions & Observations Thread

[Cfa]

Just seen several cars + vegetation burned up from mulch catching on fire. I didn’t know that could happen, but it’s been so dry, kind of scary. I was parked about 200 feet away.

[doncat]

87° here today.. winds went onshore earlier than yesterday so no 90° today.

in 2018 we had to wait for the subtropical ridge expansion to give us more S to SW flow and we got hot toward august 

This is one of those rare times when the WAR forecast has been getting weaker day 8 from day 10. We got used to the pattern of it correcting stronger day 8-10. The trough digging into the West also was a signal for an easy high temperature guidance beat. Maybe a combo of the developing La Niña, Indian Ocean warmth, and that perma-heat ridge which has been stuck over a Siberia.

Should make for an interesting winter forecast.

if we get a hot spell it will be from an atlantic ridge retrograde which can push any cutoff far enough to our east. the classic plains heat releases are just not working out this year

there wont be any ultra hot spells with a S wind, be content for temps in the low 90s.

Did you read about this incredible heat and forest fires in Siberia?  They've been +20 F in heat for like six months now and just hit 100 F- first time ever north of the arctic circle!

Unprecedented heat in Siberia which the media isn't really talking about.

I've noticed hotter temps occurring farther north this year, seems like the attic fire that started in the high Arctic has spread farther south and has now reached northern VT and Maine with temps approaching 100 there, all time records.

We've already seen the negative effects of a snowless winter here......nasty explosion of bugs this year, with a horde of gnats near my Poconos home that makes working in my garden impossible.  I thought it was just this community but when I went down the mountain to a nearby town, they were mobbing people there too!  I've also had to spray bug barrier throughout my other home on Long Island, where I now have wolf spiders along with their eggs (eek), I saw one in my bedroom and could not sleep there for a week!  They are hairy, with warning stripes on their legs, black and grey (to warn others of being poisonous) and I haven't had these in a decade or so.  I sprayed so much bug barrier to get rid of them that my throat and nose were burning!  I just hope I dont get any centipedes later on, because I haven't had them in a long time either.....it's the combo of a warm wet winter followed by a warm wet spring and now this hot humid weather that has caused this population explosion of bugs.  I wish all the birds I get in both gardens would eat them all up, but they seem to be content singing and taking baths in my pond!  We also have a 50% reduction in monarch butterflies (an important pollinator) because of pesticides killing their favorite food, milkweed, as well as the changing climate.  But now everyone is planting milkweed along the roads and highways, so maybe they will have a comeback?

yeah I doubt this is one of those extreme heat years....S wind doesn't do it here.  Good for low and perhaps some mid 90s later on in the season though.

Next summer is going to be off to the races though no doubt.

Temperatures again rose into the middle and upper 80s today. Northern New England, Quebec, and New Brunswick again saw some record heat. High temperatures included:

Burlington: 96° (old record: 93°, 1888 and 1975)
Caribou: 91° (tied record set in 1975 and tied in 1983)
Edmundston, New Brunswick: 90° (old record: 81°, 2014)
Miramichi, New Brunswick: 93° (old record: 85°, 2013)
Quebec City: 91° (old record: 85°, 2003)
Rivière-du-Loup, Quebec: 88° (old record: 81°, 1999)
Sherbrooke, Quebec: 91° (old record: 78°, 2009)

Tomorrow will be another very warm day with high temperatures well into the 80s. A few locations could experience a thunderstorm during the afternoon or evening hours.

A sustained generally warmer than normal pattern is now in place. That pattern will likely persist through at least July and August, paving the way for a warmer than normal summer throughout the region. Initially, extreme heat is unlikely, but that could change in July, especially if the emerging drought continues to deepen. One or more heatwaves are likely in July across the region.

Overnight and today, the ECMWF backed off on the extreme heat to start July and the GFS backed off on its idea of an unprecedented cool spell with three consecutive high temperatures in the 60s in New York City during the June 30-July 2 period. Based on the EPS and GEFS and overall pattern evolution, temperatures will likely be above normal as July commences (probably with high tempertures in the middle or perhaps upper 80s in New York City).

The ENSO Region 1+2 anomaly was -0.5°C and the Region 3.4 anomaly was -0.4°C for the week centered around June 17. For the past six weeks, the ENSO Region 1+2 anomaly has averaged -0.32°C and the ENSO Region 3.4 anomaly has averaged -0.43°C. Neutral-cool conditions will likely prevail through mid-summer. The probability of the development of a La Niña event during late summer or early autumn has increased in recent weeks.

The SOI was +8.93 today.

Today, the preliminary Arctic Oscillation (AO) figure was +0.044.

On June 22, the MJO was in Phase 1 at an amplitude of 1.825 (RMM). The June 21-adjusted amplitude was 1.845.

Last year, the MJO went through a very strong passage through Phase 1 during the closing days of May. About four weeks later, a warmer than normal pattern locked in and predominated through early autumn.

This year, the MJO was in Phase 1 for 3 consecutive days with an amplitude of 1.500 or above during the June 1-3 period. Since 1981, there were four such cases that saw the MJO meet or exceed those thresholds during the June 1-10 period: 2002, 2006, 2007, and 2015. While the four cases were evenly split between cooler and warmer than normal during the second half of June, 3 of those 4 cases saw a warmer to much warmer than normal July. This could be an early indication that a summer that will start with near normal temperatures overall (June) could turn warmer than normal afterward.

Last year, the SOI fell to -42.04 on June 22 when the MJO was in Phase 6. This year, the SOI plunged below -46.68 on June 5, its lowest level in more than three years. The dramatic plunge in the SOI could be the proverbial spark that kicks off a sequence of events leading to the development of a sustained warmer than normal period. Taking into consideration the MJO, that transition could begin some time during the closing 10 days of June. Further, the cases that saw both the MJO and SOI thresholds satisfied generally saw 10-20 days where the temperature reached or exceeded 90° in New York City.

Just as had been the case last year, July and August could feature warm anomalies in the East. July-August 2019 saw 13 days on which the temperature reached or exceeded 90° in New York City.

Based on sensitivity analysis applied to the latest guidance, there is an implied 91% probability that New York City will have a warmer than normal June. June will likely finish with a mean temperature near 73.8°.

Don what has been the hottest temp in the northeast so far this year?  US or Canada?  Thanks!

 

[doncat]

Another euro run with basically no significant rain thru it's run to the coast. It's been pretty consistent with that idea for a few days now, while the gfs and cmc at times have looked quite wet out ten days. 

[CIK62]

The last 7 days of June are averaging 77degs. , or 2.5degs. AN.

Month to date is  +2.0[72.5].           June should end at  +2.2[73.6].

75* here at 6am., moderate overcast-kept the heat in.     78* by 10am, less cloud cover.       79* by Noon, %RH way down in the last 6hrs. to 55%.         85* by 4pm, 42%RH---west wind kept my T in the running after lagging so all the other recent days.         Remembering last Oct. 02 on the beach with 93* locally too and  those westward moving dust devils that forced me from the beach a little earlier than I wanted.

I've seen 1 Monarch and it flew past without stopping in my garden Bees are a rarity too. I've been hand pollinating many things this year, so far so good but that's not sustainable. I'm not sure if I was successful with the melons but I sure hope so because I have a dozen growing and I've been looking forward to them for weeks. Early on while it was still wet I had all sorts of bugs, now it's down to grubs and these things that look like centipedes but with fewer legs. The gnats and skeeters are pretty much gone since it dried out.

Another day without rain? Not a good way to start the summer. As we have seen in the past drought often leads to more drought.

Clouds hauling through with a more westerly wind now and p to 78. Where as yesterday was below forecast today with a more westerly flow may out do guidance similar to monday.  So ares will approach or reach 90, enhanced by the recent dryness. Sat and Sunday should see temps again exceed 90 in a more widespread fashion ahead of the next trough and subsequent ULL.

Overnight runs with the return of the onshore flow that went let go until Independence day weekend.  This time the ULL cut off may be closer by and muddy up 6/30 - 7/3 with more with clouds and rain  then sunny cool and dry weather we had the past two where the ULL was much further south.  I do think we warm things up by Sat/Sun (7.4 -7/5) and the week beyond the 4th holiday..  Get the flow N / NW and 850 temps are an ocean of >18C.  These tendencies of ULL that linger 4 - 6 days may finally see that progression north and east of the area beyond the first week of July.  Overall 

 

[SACRUS]

June departures through 6/24 (7 days to go).  I remeber last year with the searing heat in the Southeast and now into the northeast. Sandwiched so far.

Missed all but a sun shower since Friday where i was lucky to get 0.10.  Perhaps with the ULL now forecast to be close by and essentially over the region bewteen 6/30 and 7/3 maybe we can see some widespread rains.  We shall see if models start showing anything more widespread.  Past ULL in May and last week had some decent rains where the ULL st for a few days.
