I hear many people mention the term alarmist in regard to climate change. But I see very little alarmism in terms of the actual global response to climate change. Complacency will probably turn out the biggest risk that we face.

Many people who have been leaving California relocated to around Boise, Idaho. That is one of the hottest property markets in the country right now. A bunch of Hurricane Maria refugees from Puerto Rico wound up in Buffalo. Past history Is full of examples of people migrating from the tropics to more temperate zones. But this will probably accelerate in coming decades. Is Idaho prepared for climate refugees from California? https://www.idahostatesman.com/opinion/readers-opinion/article237278474.html Wildfires in California are igniting more than chaparral and forest. They are firing up additional reasons Californians will seek safer, blackout-free homes in Idaho. An Oct. 28 San Francisco Chronicle article sounded an ominous alarm: “fires intensified fears California has become almost too dangerous to inhabit.” This is exceedingly bad news for Idaho. For our state to remain the place we love, Idahoans should be cheering for California to address its problems lest they soon become our own. We should acknowledge that the entire arid American West shares a common danger, and Idaho is not exempt.

The major trend over the years has been a migration of our population to places which have been subject to a record number of billion dollar weather and climate disasters. The West has been drying out with an record amount wild fire damages. The big population increase in Texas has been hammered by record flooding and hurricane damages with storms like Harvey. Florida has had a double whammy of sea level rise and billion dollar hurricane damages. So now their residents are seeing steep property insurance increases. The same goes for fire prone areas of the West. My guess is that the coming years will see a reverse migration away from these areas. Property insurance increases will price residents out of those markets. So they will look for areas of the country that don’t see as many billion dollar events. The future of population growth may be back to cooler parts fo the country. But such a change may take time since people love living in the Sun Belt.

Their water usage has actually been declining in recent years. So it shows you how historic this current drought is. If the Colorado Basin doesn’t see an increase in precipitation the next few years, then they will have to institute drastic cuts. It looks like the first level of cuts will begin by by later this summer. https://www.circleofblue.org/2020/world/remarkable-drop-in-colorado-river-water-use-a-sign-of-climate-adaptation/ Use of Colorado River water in the three states of the river’s lower basin fell to a 33-year low in 2019, amid growing awareness of the precarity of the region’s water supply in a drying and warming climate. Arizona, California, and Nevada combined to consume just over 6.5 million acre-feet last year, according to an annual audit from the Bureau of Reclamation, the federal agency that oversees the lower basin. That is about 1 million acre-feet less than the three states are entitled to use under a legal compact that divides the Colorado River’s waters. The last time water consumption from the river was that low was in 1986, the year after an enormous canal in Arizona opened that allowed the state to lay claim to its full Colorado River entitlement.

The Northeast is getting warmer and wetter while the Southwest is becoming warmer and drier.

Somebody out West may be able to finish the month at +10 or greater. Looks like the pattern tries to reshuffle a bit later in June. More of a WAR and Plains trough with ridging along the West Coast.

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.

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

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.

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 EPS forecasts

Weekends since late May have been alternating between record heat and backdoor cold fronts. May 22-23 had record heat and May 29-30 featured record cold and wet. June 5-6 we were back to record heat. Now this weekend will feature clouds with breaks of sun and a cooler onshore flow.

This was the warmest first 10 days of June on record at Newark. But the maximum temperature of 97° came in lower than the 99° in 1999 and 102 in 2011. So a continuation of the difficulty in reaching 100° in recent years. The 100° temperatures were located to our west where the most extreme drought conditions were located. The record heat and ridging will pull back to the West during mid-June intensifying the drought conditions there. While the drought locations and intensity is different from 1999 and 2011, those years both featured record heat in July for our area. Perhaps this means we can make a run on 100° in July. But we have seen how the maximum temperatures in early June were 2 to 5°lower than 1999 and 2011. So it will be interesting to see how July turns out. As for the tropics, the first potential for this year looks to be near the TX/LA Western Gulf region. This would follow the recent stuck pattern of cooler and wetter in that region undercutting the ridge across the north.

This is turning out to be a new benchmark for early season heat in Minnesota. https://www.dnr.state.mn.us/climate/journal/june-2021-heat-wave.html Minnesota has had many historical heat waves that were "worse" than this one on numerous counts. However, at many locations, this was the longest and most severe heat wave to occur so early in the season. It's not unusual have have several days or more of 90-degree weather during the middle of July, but it is unusual to do so during (or before) the first half of June. In the Twin Cities, where the heat-retaining urban and suburban infrastructure helped elevate temperatures even further, this heat wave has tied the record for consecutive high temperatures of at least 90 F on or before June 15, and obliterated the record for similar early-season consecutive low temperatures of at least 70 F--both officially at six straight days through June 8th. The low temperatures in particular have been incredibly high in the Twin Cities, and so even though other historical heat waves produced higher daily maximum temperatures, not have come anywhere near this one in terms of daily average temperatures. Records of note set during June 2021 heat wave: Duluth, June 4-5: earliest-in-season occurrence of two consecutive high temperatures above 90 F International Falls, June 4: highest temperature on record so early in the season (98 F) Twin Cities, June 5: highest minimum temperature on record so early in the season (78 F) Twin Cities : most consecutive low temperatures at or above 70 F so early in the season (six, ongoing) Below is a table of daily highs and lows at Minnesota's five major climate stations, from June 3 through June 11, 2021.

The closer you were to New England, the hotter the last several summers have been. A very impressive run of summer heat across the region since 2010. We never had this many top 10 warmest summers in such a short period of time. 2020 was the warmest summer on record at LGA, BDL, BTV, and CAR. It was the 2nd warmest summer for ISP and BDR.

BTV is the place to be if you like record warm early season water temperatures. This tweet was back on May 21st. Our local SSTs usually peak in July into August.

Yeah, mid to upper 90s is still plenty hot especially with the higher humidity since the super El Niño. This has been the longest streak at Newark not to reach 100°. So you can see how unusual this more onshore flow summer heat pattern has been.

The record heat last several summers in New England is overlapping the lingering cool and wet pattern in Texas since the historic Arctic outbreak.

So far this season, the ridge axis has been pushed up to the north of our latitude. This was the same story from 2018 to 2020 with the most impressive record highs to our north. This lead to more onshore flow and record high dew points. Plenty of mid to upper 90s heat with the 100°+ maxes at places like LGA and points north. Almost like a version of the SE US Coastal summer moist trade winds pattern. Those places have very high 90° day counts but not many 100° days. Our last widespread 100°s at all stations from EWR to ISP was back the 2010 to 2013 era. The ridge axis was right over the Great Lakes with a strong westerly flow pattern. Same for the July 1995 heatwave. The ridge axis in recent years has stretched further north allowing the warmest 850 mb temperatures to go to our north. That difference has allowed more of a southerly component to the flow than westerly. So we’ll have to see how the ridge axis rebuilds once we get to late June and July. June 2021 so far Peak July heat pattern since 2018 2010-2013 pattern with mid July 1995
