The weekend will be partly to mostly cloudy and somewhat cooler than normal. However, some warming is likely on Monday. Overall, despite a cooler weekend, the first half of June will likely wind up much warmer than normal.

Out West, Phoenix will very likely see the development of a period of extreme heat this weekend into at least early next week. The temperature could reach 115° on one or more days, especially during the Monday-Thursday period. For reference, Phoenix's daily records for the June 13-18 period are posted below.

Record high maximum temperatures:

June 13: 114°, 1896 and 1936
June 14: 115°, 1987
June 15: 115°, 1974
June 16: 115°, 1974
June 17: 114°, 2014
June 18: 115°, 1989 and 2015

Record high minimum temperatures:

June 13: 87°, 2018
June 14: 90°, 2018 (earliest 90° low on record)
June 15: 88°, 1936
June 16: 86°, 1988
June 17: 88°, 1986 and 2008
June 18: 88°, 2008

It should also be noted that the earliest temperature above 115° occurred on June 19, 2016 when the temperature reached 118°. A year later, the temperature again reached 118°. This record will likely be broken.

This unseasonable heat will likely extend northward into southern Canada including Alberta and Saskatchewan. It remains uncertain whether this extreme air mass will impact the region at some point later in the month.

The ENSO Region 1+2 anomaly was -0.4°C and the Region 3.4 anomaly was -0.2°C for the week centered around June 2. For the past six weeks, the ENSO Region 1+2 anomaly has averaged -0.65°C and the ENSO Region 3.4 anomaly has averaged -0.30°C. Neutral ENSO conditions will likely prevail into at least mid-summer.

The SOI was -3.16 today.

The preliminary Arctic Oscillation (AO) figure was +1.460 today.

On June 9 the MJO was in Phase 8 at an amplitude of 0.512 (RMM). The June 8-adjusted amplitude was 0.746 (RMM).

In late April, the MJO moved through Phase 8 at an extreme amplitude (+3.000 or above). Only February 25, 1988 and March 18-19, 2015 had a higher amplitude at Phase 8. Both 1988 and 2015 went on to have an exceptionally warm July-August period. July-August 1988 had a mean temperature of 79.1°, which ranked 4th highest for that two-month period. July-August 2015 had a mean temperature of 78.9°, which ranked 5th highest for that two-month period. September 2015 was also the warmest September on record. The MJO's extreme passage through Phase 8 could provide the first hint of a hot summer.

With Phoenix very likely to reach 115° or above next week, that development could provide another hint of a warmer than normal summer. Since 1896, 76% of years that saw Phoenix reach 115° or above in June had a warmer than July-August. The ratio of top 30 July-August temperatures relative to bottom 30 temperatures was 6:1 in favor of the warmth. Overall, the ingredients continue to fall into place for a warmer than normal to potentially hot summer.

Based on sensitivity analysis applied to the latest guidance, there is an implied 73% probability that New York City will have a warmer than normal June (1991-2020 normal). June will likely finish with a mean temperature near 74.2° (2.2° above normal).

The next 8 days are averaging 71degs.(63/78), or -1.0.

Month to date is  74.5[+5.4].        Should be 73.0[+2.7] by the 20th.

Next 10 days showing no real heat.       EURO has trouble getting above 80.       Heavy rain in two weeks possible on GFS.

66*(80%RH) here at 6am. broken overcast.         Got to 72* around 6pm, breaks of sun late in the day.        67* at 7pm.

This June is roughly following a series of 10 day patterns. Our first 10 days featured record heat. The middle part of the month has the record heat pulling back to the West. So we see more of a trough and less heat through around the 20th. The EPS has a warmer ridge signal returning during the last 7 to 10 days of June. The main uncertainty for late June is how warm will it get. Will it approach the record levels of early June or be a less impressive warm up?

June 1-9

Morning thoughts...

Today will be partly to mostly cloudy and cool. Temperatures will likely reach the lower and middle 70s in most places. Likely high temperatures around the region include:

New York City (Central Park): 73°

Newark: 76°

Philadelphia: 77°

Tomorrow will be variably cloudy with high temperatures in the middle 70s.

Out West, record-breaking heat will develop in Phoenix. The temperature will likely reach 115° on one or more days, especially during the Monday-Thursday period. It is likely that Phoenix will see its earliest 116° or above temperature on record. The unseasonable heat will likely extend northward into southern Canada including Alberta and Saskatchewan.

Cooldown into day two.  Cloudy but likely no rain today and some breaks of sun.  Tomorrow and Monday similar but a batch of rain / showers coming later Sunday and Monday.  Overall week to  10 day cooldown which began Friday 6/11 - 6/18.  Ridge out west means business the next 10 days with pieces of that immense heat ejecting east , first between 6/19 - 6/23 bringing pending on clouds/storms the next shot at 90s for the area.  ECM does bring  850 Temps >16c but on the northern edges of the heat ejections which come with storms. 

 

Longer range does show more ridging progressing into the EC 6/24 and beyond.  We'll see if the Rockies ridge is shunted east or WAR can build west. Oevrall warm to hot June.

 

Cooldown dailies

6/11

EWR: 73/65 (-2)
JFK: 71/61 (-3)
NYC: 69/62 (-4)
LGA: 68/62 (-6)
TTN: 65/58 )-7)

The thing I find odd is that so few of the high 90 degree summers are on this list.  Just off the top of my head I would've thought 1966, 1980, 1983, 1991, and 1993 should be near the top.

 

We had shorter duration but memorable heat in 1966, 1980, and 1983. But those summer averages over 3 months lag behind our modern day summers. 1993 was an interesting case. It was really hot at EWR and NYC before the vegetation got out of control. But it wasn’t nearly as warm for JFK,LGA, and ISP. As for 90° day statistics, 2010 is in a class by itself at the top. With the record high dew points and onshore flow in recent years,  a summer like 2020 ranked very high due to many days in the upper 80s and 90s. While LGA was the standout for 95°+ days, all local stations ranked near the top for summer average high, low, and average temperatures.

it looks like the 11 year hot summer cycle is under way...many of them had a cool period in May or June...July 1988 started the month with the second coolest July temperature on record before going on to have a very hot July and August...the first 11 days in June 1988 were quite cool...then five straight 90 degree days and eight all together before the cool down at the end of the month...1955 had a cool June...2021 has already had a heat wave and I expect more to come...

Tomorrow will be partly to mostly cloudy and again somewhat cooler than normal. However, some warming is likely on Monday. Overall, the first half of June will likely wind up much warmer than normal.

Out West, an extreme heatwave is now developing in the Southwest, including Phoenix. Late this afternoon, the temperature reached 110° in Phoenix for the first time this year. Last year saw a record 53 such days (prior record: 33, 2011). The least 110° days on record was 0, which was set in 1911. The average number of such days per year is 20.3 (1991-20 normals), which was an increase of 2.3 days from the 1981-10 normals.

The extreme heat will likely continue through much of next week. The temperature could reach 115° on one or more days, especially during the Monday-Friday period. For reference, Phoenix's daily records for the June 13-18 period are posted below.

Record high maximum temperatures:

June 13: 114°, 1896 and 1936
June 14: 115°, 1987
June 15: 115°, 1974
June 16: 115°, 1974
June 17: 114°, 2014
June 18: 115°, 1989 and 2015

Record high minimum temperatures:

June 13: 87°, 2018
June 14: 90°, 2018 (earliest 90° low on record)
June 15: 88°, 1936
June 16: 86°, 1988
June 17: 88°, 1986 and 2008
June 18: 88°, 2008

Phoenix will very likely see the earliest temperature above 115° on record. The existing record was set on June 19, 2016 when the temperature reached 118°. That record was tied in 2017.

This unseasonable heat will likely extend northward into southern Canada including Alberta and Saskatchewan. It remains uncertain whether this extreme air mass will impact the region at some point later in the month.

The ENSO Region 1+2 anomaly was -0.4°C and the Region 3.4 anomaly was -0.2°C for the week centered around June 2. For the past six weeks, the ENSO Region 1+2 anomaly has averaged -0.65°C and the ENSO Region 3.4 anomaly has averaged -0.30°C. Neutral ENSO conditions will likely prevail into at least mid-summer.

The SOI was +1.41 today.

The preliminary Arctic Oscillation (AO) figure was +1.086 today.

On June 10 the MJO was in Phase 2 at an amplitude of 0.136 (RMM). The June 9-adjusted amplitude was 0.512 (RMM).

In late April, the MJO moved through Phase 8 at an extreme amplitude (+3.000 or above). Only February 25, 1988 and March 18-19, 2015 had a higher amplitude at Phase 8. Both 1988 and 2015 went on to have an exceptionally warm July-August period. July-August 1988 had a mean temperature of 79.1°, which ranked 4th highest for that two-month period. July-August 2015 had a mean temperature of 78.9°, which ranked 5th highest for that two-month period. September 2015 was also the warmest September on record. The MJO's extreme passage through Phase 8 could provide the first hint of a hot summer.

With Phoenix very likely to reach 115° or above next week, that development could provide another hint of a warmer than normal summer. Since 1896, 76% of years that saw Phoenix reach 115° or above in June had a warmer than July-August. The ratio of top 30 July-August temperatures relative to bottom 30 temperatures was 6:1 in favor of the warmth. Overall, the ingredients continue to fall into place for a warmer than normal to potentially hot summer.

Based on sensitivity analysis applied to the latest guidance, there is an implied 74% probability that New York City will have a warmer than normal June (1991-2020 normal). June will likely finish with a mean temperature near 74.2° (2.2° above normal).

I thought 2010 was pretty amazing for JFK, because it's the only one that had 30+ 90 degree days there (31) and they also had 10+ 95+ degree days (11)!  Three days out of four around July 4th weekend were above 100 there!  I wonder if that'll ever happen again?  It almost seems like the 1995-96 of summers.

1993 had that torrid heatwave after July 4th weekend, I don't know why it seems so much worse than 2010 just for that particular heat wave.  Maybe because that was the last summer I went without AC?  Do you remember it- even JFK had two days above 100 degrees in a row, while NYC had three, and EWR had an astounding 5 (including two in that stretch that reached 105!)  I think EWR finished with an amazing 9 100+ degree days!  Do you think they could ever get 10 of those days?

 

Going back to 1980, I remember that was the first heatwave that I analyzed.  We had an 80 degree average for 2 months- July and August!  That was pretty amazing.  I remember reading that hundreds of people died in St Louis- not so amazing.    But the heatwave covered the country from the third week of June through the third week of September, so pretty much the entire summer.  1983 had one of the hottest three month averages I'd seen, and with the record rainfall, it also had one of the most humid summers we've ever had.  On top of that temps were still hitting 99 in September and still in the mid 90s as late as the equinox and a few days after!

and we must remember this 11 year hot cycle covered the entire continent, so the drought and heat in the west and even the midwest could be the start of a coast to coast megaheatwave.

It is hot out west in places such as Phoenix. I sometimes wonder how people like such heat. The average high out there at this time of year is over 100 degrees. Not only do you have the heat but the average June precip. is only .09 of an inch. I think that constitutes a desert.

without humidity it's pretty good.

100 degrees and low humidity is great weather to run in even here.

Once it gets above 110 I dont like it so much.

The next 8 days are averaging 73degs.(64/81), or just Normal.

Month to date is  73.8[+4.5].         Should be about  73.5[+2.7] by the 21st.

TS in the GoM has most runs into LA., (20th)then a semi-broad turn to the right, so rain misses us w/o phasing.

62*(88%RH) here at 6am, m. clear for now.      Should be cloudy by 1pm.

You can see how many summer top 10s there have been at JFK and other stations just since 2010.

Morning thoughts...

Today will be partly to mostly cloudy and somewhat warmer. Temperatures will likely reach the middle and upper 70s in most places. Likely high temperatures around the region include:

New York City (Central Park): 76°

Newark: 79°

Philadelphia: 79°

The somewhat cooler than normal temperatures will likely persist through midweek. Afterward, a warmer regime could begin to evolve.

Out West, record-breaking heat will develop across the Southwest, including Phoenix. At Phoenix, the temperature will likely reach 115° on multiple days, especially during the Monday-Friday period. It is likely that Phoenix will see its earliest 116° or above temperature on record. The unseasonable heat will likely extend northward into southern Canada including Alberta and Saskatchewan. 

Daily Records for June 13:

Phoenix: 114°, 1936 (Forecast: 112° to 116°)

Tucson: 110°, 1924 (Forecast: 111° to 113°)

*-Forecast range is 1 sigma below and above the forecast mean.

Tucson set a daily record high temperature of 110° yesterday. The old record was 109°, which was set in 1924 and tied in 1933 and 1995.

Clouds burning off here and up to 70.  We'll see how long we can stay sunny before clouds and showers arrive later.  Day 3 of the cooldown which should go through the work week with some warming towards above normal by Tuesday before Wed - Fri turn cooler. 

Rockies ridge firing on all cylinders and should produce may records into the deserts and northern plains 6/14 - 6/19.  Pieces of the heat factory  heat look to spill east in the 6/19 - 6/21 period and offer our next shot at 90s, but ridge position should push storms in to the region in that period as well. 

Beyond there 6/22 and on hints of  more widespread warmth and heat plus looks to build east as riding.  Its 10 days away but perhaps a more steamy pattern.  We'll see if the WAR building west gains any persistence in the coming forecasts,  Warm to hot June overall.

You knew that the ridge had to eventually pull back to the West with cooling from the Plains east. It’s just too difficult for the Upper Plains to run a +15 or higher monthly departure during the summer. That is more like what happed during some recent winter and early springs.

ECM has 850 temps >18C building into the upper MW/ GL by next Saturday again.  It May be a 5 - 7 day break before theyre  back into the frying pan perhaps shunted south a bit from the prior record heat.  We'll see if we can see that spill east Fathersday and the week of 6/21.
