Chilly nights!

Last Zero
The last couple of nights have been chilly across New Brunswick with overnight lows in the low single digits.

While Greater Moncton fell to 5.5°C which was a few degrees away from the record, the same minimum in Bouctouche was cold enough to set a new low.

Edmundston dipped to a nippy 1.1°C which tied its record as did Grand Manan when it dropped to 3.8°C.

Over the last six years in Greater Moncton, the chart above shows temperatures have not fallen to the freezing point or lower after early June.

Thundersnow in B.C.!

A thunderstorm with snow is called thundersnow and it struck the British Columbia Interior just two days before the start of summer!

An unstable air mass bringing cold air from Alaska is to blame for the rare thundersnow which covered mountainous terrain in the Okanagan Valley with about 10 cm.

Snow fell above 1500 metres with a snow/rain mix down to 1100 metres and a chilly rain at sea level.

About 10 cm of snow was also expected in the Alberta Rockies from a similar system.

April 2019 – Wet and chilly

Spring can be the most disappointing season of the year in New Brunswick and April 2019 was no exception with cloudy, cool and often wet conditions.

Surprisingly, Greater Moncton was close to normal in temperature but double the average amount of rain fell along with slightly more snow than usual.

Melting snow and heavy precipitation led to more disastrous flooding along the St. John River – almost as bad as last year’s historic water levels.

Only one day was fully below freezing and while nights weren’t that cold, daytime highs often struggled to reach the double digits.

Juneuary!

When it snows in June it might as well be January which gives us a new month called Juneuary!

It may now be summer but an icy rain changed to snow in central Newfoundland and the Cape Breton Highlands today.

Gander set a new record with 2 cm of snow and Environment Canada said it has never snowed on 26 June before.

Thanks to a chilly rain, Greater Moncton reached a daytime high of only 11.0 C yesterday which was colder than the average overnight low of 12 C.

Average temperatures in Southeast New Brunswick have been running about three degrees below normal this month.

Goodbye Spring!

Dorchester Beach, NB, 17 June 2018 (Dearing)

Spring had its inevitable ups and downs in Southeast New Brunswick but overall the average temperature was close to normal for March, April and May.

March was very stormy with a parade of Nor’easters which led to the highest snow depth of the winter in Greater Moncton by the end of the month.

April was slightly colder than normal with chilly nights until mid-month and the last measurable snow fell on the 21st.

May had slightly above normal temperatures overall thanks to 14 days with daytime highs of 20 C or more but nights remained cold with single digit lows.

So far this June, the mean temperature is running three degrees below average with a hard frost on the 4th which was the coldest minimum since 16 April.

Record lows in Maritimes

Temp0degrees
We are now several weeks into the growing season and temperatures are dropping to dangerously cold lows.

Farmers are concerned about damage to crops after a cool air mass and clear skies led to a frigid low of -4 C in parts of New Brunswick and Nova Scotia overnight.

Greater Moncton dropped to -3.2 C early today which broke the old record of -2.2 C from 1903 and records go back to 1881.

The following new record lows were set on 04 June:

  • Kouchibouguac National Park, NB -3.8 C (records since 1924)
  • Grand Manan, NB -2.2 C (records since 1883)
  • Port Hawkesbury, NS -2.6 C (records since 1875)
  • Ingonish, NS -2.2 C (records since 1950)
  • Summerside, PEI -1.9 C (records since 1898)
  • Charlottetown, PEI -1.0 C (records since 1872)

Despite chilly weather, snowbanks are melting in NE Moncton, 16 April 2018 (Dearing)

Mid-April is here already but temperatures certainly haven’t been improving very much lately in New Brunswick.

Overnight lows continue to be abnormally cold with records set on Sunday, 15 April.

Greater Moncton fell to -9.1 C which breaks a record low of -8.6 C from 1981.

New records were also set in Bouctouche at -8.6 C and Miscou Island at -9.3 C.

Mild for Santa’s arrival

The Greater Moncton Santa Claus Parade is the unofficial start to the Christmas season in Southeast New Brunswick.

The weather was cooperative for Santa’s arrival this year with a mild 10 C when the parade started at 5pm with light winds under clear and dry conditions.

It was a different story last year with a chilly 3 C under a mostly cloudy sky with damp conditions.

An estimated 100,000 spectators come out to see the parade every year and this year the crowd seemed even larger.

Clear skies and an Arctic air mass lowered temperatures in Greater Moncton to a chilly -9.0 C on November 12th and 13th.

Recent data shows temperatures that low (within 2 and 3 degrees of record lows) typically don’t occur until later in the month and the thermometer failed to climb above freezing on the 12th which is also earlier than normal.

A new record low was set at the Saint John Airport when it fell to -11.3 C on the 12th.

Quite a contrast from just a week ago when several communities in New Brunswick climbed into the low 20s Celsius.

Decent first half of July

For whatever reason, summer seems to go by faster than the other seasons and here we are already at the midway point of July. 

After 16 days, Greater Moncton has been having a decent month with an average temperature of 19.3 C which is 0.5 degrees above normal. 

Daytime highs have been warm but not hot with a peak of 29.4 C on 16 July while overnight lows have been mild except for a chilly low of 8.9 C on  05 July. 

The only concern is a lack of rainfall. 

The tally is 19.8 mm so far – less than a quarter of the monthly total – but keep in mind we are entering what is traditionally the driest period of the year in Southeast New Brunswick.
