Vermont Temperatures In June Were A Roller Coaster

Story of June, 2020. In a dry month, this thunderstorm teased
by poking above the treeline behind my St. Albans, Vermont house
then quickly scooted away, making sure I didn't get
any needed rain. Photo taken June 23.
Most of the time, I rate June and September in Vermont as the mellowest times of the year in the weather department.

True, months like June can have some pretty impressive rainfalls, floods and severe storms. But the two months I mention aren't generally known for temperature extremes, or big swings from one day or week to the next.

This June, though, was a roller coaster for sure.

In the first half of the month there were a couple days setting date records for the chilliest high temperatures - reaching only the 50s.

By the second half of the month, we were in a record heat wave.

Burlington's swings were common for what the state saw in June. We awoke to temperatures in the 30s on June 1, with frost in the cold spots. By the 5th, it was 90 degrees.  On the 13th, high temperatures were only in the 50s. By the 18th, Burlington was starting its June record breaking six consecutive days in the 90s.

Also in Burlington, there was very little rain all month, until the last two days, when 1.14 fell.

Overall in Burlington, the average temperatures for the month worked out to 69.0 degrees. That was 3.1 degrees above normal and enough to make June the tenth warmest on record.

June's temperature was closer to normal in towns away from the Champlain Valley, I think mostly because unlike the Champlain Valley, partial clouds and daily scattered thunderstorms tempered that long heat wave a little over the Green Mountains and points east.

So far this year, we've had nine days at or above 90 degrees in Burlington. Average for an entire year is five, so were off to a fast start in the hot weather department.

Pretty much everyone in Vermont was dry in June. Despite the rainfall in the last two days of the month, Burlington ended with only 1.88 inches of precipitation for June, which is right around half of normal.

Most other places in Vermont had similar precipitation deficits. An exception was Montpelier, which was lucky enough to be in the path of several thunderstorms during the month. They were only a third of an inch shy in rainfall, with a June total of 3.47 inches.

As always, what the next month will bring could be anything. However, there is a pretty remarkable, but not universal consensus that July will be hotter than average in New England. The first few days of the month, at least, look to be warmer than average.

Long range forecasts have been putting us in a moderate risk of a heat wave during the second week of July. We'll see how that pans out.

It could have been worse.  Miami, Florida just endured more than six days in which the heat index was 90 or more. This includes every hour during that period, including nights. Ugh!

Hot Times Go On: Worldwide, May Was Hottest, Or At Least Tied For It

Extreme warmth, relative to average, in Siberia was a big contributor to
make May, 2020 the warmest on record for the globe. Eastern North
America was one of the few coolish spots. 
Last week, the numbers came out on how the world fared climate wise in May.

To almost nobody's surprise, we're #1 again.

May was the hottest on record for the world as a whole, according to several monitoring agencies, including NOAA's Centers for Environmental Information.

It's been a hot decade, too.  Each of the seven warmest Mays have occured in the past seven year, according to NCEI.

Siberia basically pushed the world over the top in terms of May heat.  Relative to average, that part of the world was off the charts warm.

The only relatively cool spots were eastern Canada, eastern United States, Australia and parts of eastern Europe.

If anything, the trend in global warming has accelerated in the past several year. Each of the past 12 months have either been the hottest or second hottest on record on a global basis.

According to Jeff Masters, writing for Yale Climate Connection:

"The year-to-date period January-May ranks as the second warmest such period on record, just 0.06 (degrees Celcius) behind the record set in 2016.  According to NCEI's annual temperature outlook, the year 2020 has more than a 99.9 percent chance to rank among the five warmest years on record, and a 49 percent chance of being the warmest year on record. If so, calendar 2020 would mean each of the past seven years would be among the seven warmest on record."

As noted last month, global economic lockdowns to slow the spread of the coronavirus will probably reduce carbon emissions by 5 to 8 percent from the record highs of 2019. Even with that reduction, carbon dioxide concentrations in the atmosphere will continue to grow.

Plus, the coronavirus crisis might only last another year or two.  That's way too long for us humans, who hate to see these tragc deaths and illnesses from the virus. In the grand scheme of things, though, the coronovirus problems won't last long enough to cause any dent at all in atmospheric carbon concentrations.

According to USA Today, Kennth Gillingham, a climate economist at Yale University was pretty clear on this, saying, "The only reason emissions dropped is that we're all stuck at home....As soon as the lockdowns lift, they are likely to rise again."

For those of you keeping track, May, 2020 was the 425th consecutive month with above normal global temperatuires.

Roller Coaster May Was Near "Average" But Not Really

A St. Albans, Vermont daffodil shivers in the snow on May 9. By
the end of the month  the same gardens were wilting in record heat
If you like changeable weather, May was surely your month here in Vermont.

The weather gave us a little bit of everything: Snow, record heat, subfreezing cold and severe weather.  No locusts that I'm are of, though.

This was the only May on record in Burlington with both measurable snow and 90 degree heat. As reported last week, that 95 degree reading on the 27th was the hottest temperature on record for the month of May, besting the old record by two degrees.

If you take all the extremes we had this month, you end up with a May with near normal temperatures.  Never mind that there were few actual days that were near normal.  Combine near record cold with record heat and you get something lukewarm, I guess.

In Burlington, the mean temperature for May, 2020 was 57.9 degrees, or 1.6 degrees above normal. Most other weather stations in northern Vermont, including Montpelier, St Johnsbury and Morrisville,  had a month that averaged out a little on the cool side.

If you ignore the Mother's Day weekend snows, the record heat near the end of the month and two severe weather outbreaks - which is a lot to ignore - the month overall was quite pleasant, with plenty of sunny days.

It was a dry May in Vermont, meaning garden irrigation got off
to an early start 
The inevitable result of all those sunny days, of course, is a dearth of precipitation. All of Vermont was solidly on the dry side in May.

That ranged from just a bit below normal in St. Johnsbury to more than a half inch below normal in precipitation elsewhere.

Both Burlington and Montpelier were on the dry side by nearly an inch, and Springfield's May precipitation was nearly an inch and a half below normal.

When it did rain in May, it was sometimes accompanied by dangerous weather. One round of severe weather prompted a tornado warning in southwestern Vermont on May 15. Though no tornadoes touched down in Vermont, there were aeveral reports of wind damage in the southern half of the state.

Another round of severe weather caused scattered damage throughout Vermont, but especially in the southwestern part of the state again.  I also saw some minor erosion damage around from torrential downpours. You can get that during dry months, even.

True to form, May closed with another wild shift in the weather with another cold shot. Snow was reported yesterday atop Mount Mansfield. Especially during light rain showers, mid-afternoon temperatures dipped into the 40s across northern Vermont at a time of day and year when it should have been around 70 degrees.

As June opened this morning, scattered frost iced up a few parts of Vermont and surrounding areas. It was 27 degrees in Saranac Lake, New York this morning and 32 degrees in Bennington. It was 39 degrees in Burlington, making it I believe the first time in several years that Burlington got under 40 degrees in June.

Upcoming May Heat Wave Could Bring An Odd Weather Record

Like yesterday, more comparison photos. One of my frozen gardens
in St. Albans, Vermont on May 9, this year.,.........
Kudos to WPTZ-TV meteorologist Tyler Jankoski, who alerted us to one of those weird potential records that fascinate us weather geeks.

This is Vermont, afte rall, so there's been measurable snow in Burlington during several Mays in the 128 years of weather records there.

There have also been several Mays with temperatures of 90 degrees or hotter. But those two things have not happened during the same May in this past century and quarter.

Until likely this year. Barely, though.

On May 9 this year, 0.1 inches of snow accumulated at the official National Weather Service site in South Burlington. Now, there's a decent possibility that temperatures in Burlington could reach 90 degrees Tuesday, and possibly Wednesday and Thursday. That would be a new one for May!

I've been comparing this month a lot to May, 1977, when basically the same thing happened. It snowed in most of New England that year on May 9 - the same day of the month it snowed this year. However, Burlington only received a trace of snow in May, 1977, so it wasn't measurable there.

Same garden this morning as we ramp up toward 90 degree
heat later in the week. 
By May 21-23, 1977, the temperature was in the low 90s.  It was only one of two official May heat waves in Burlington. (It's officially a  heat wave in these parts if the temperature is 90 degrees or warmer on three or more consecutive days).

And on May 23, 1977 the temperature reached 93, to establish an all-time high temperature for the month of May.  That record was subsequently tied in 2017.

It's unclear whether we'll get three days in a row with 90 degree temperatures this upcoming week. It's even more doubtful we'll get to 93 degrees or past that, but you never know.

However, it's amazing how weather has repeated itself so precisely in May, 1977 and 2020.

I'm not sure I'm loving the idea of such hot weather already. Sure, I detested the snow earlier this month and have really enjoyed the sunny, warm, but not hot conditions over the past week.  It will turn more humid during the upcoming hot spell as well, so it will be uncomfortable.

Fortunately, it looks like we'll continue the pattern of May, 1977 this year. That year, in 1977, high temperatures cooled to the 60s and 70s during most of the final days of that month. Longer range forecasts suggest the same will happen this year.

Not that history will keep repeating itself - it probably won't - but the subsequent summer of 1977 was for the most part coolish except for one week of exceptional heat in mid-July that year.

Weather Channel To Interview Presidential Candidates On Climate

The Weather Channel will interview nine presidential candidates
on the subject of climate change. 
The Weather Channel is wading into the politics of climate change.

The popular weather network will interview nine presidential candidates on the topic of climate change, according to the Associated Press.

Rather than  have a town hall style thing or a debate, which just usually devolves into "I'm better! I'm better!" the Weather Channel will conduct individual interviews.

However, Donald Trump declined to be interview.  He doesn't believe climate change is anything to worry about. Probably a Chinese hoax or something, he says.

Arguably the Democratic front runner, Joe Biden, wasn't interviewed. His campaign said the problem was scheduling conflicts, reports the AP.

Candidates will be interviewed at specific sites that highlight climate change.  For instance, Sen. Bernie Sanders will discuss the issue in a California town wrecked by wildfires. Sen. Kamala Harris will talk at a flood-prone spot along the Mississippi River.

The AP says all three Republican challengers to Trump agreed to interviews. They are Joe Walsh, Bill  Weld and Mark Sanford.

Besides Sanders and Harris, other Democratic candidates to be interveiwed are Sen Cory Booker, Sen. Elizabeth Warren, former Rep. Beto O'Rourke and Mayor Pete Buttigieg.

The Weather Channel admits that some people find the network a refuge from politics and might be dismayed by this series. But the network says a lot of viewers are interested in the subject.

I agree. I hope these are thoughtful interviews and I hope the journalists questioning the candidates don't let the politicians slide by with platitudes. The candidates  need to back up their statements and  reveal, as thoroughly as possible, their plans.

Climate change is finally becoming a big concern to voters and not a moment to soon.  It will be a major issue in the 2020 campaign, so kudos to the Weather Channel for doing this.
