Autumn arrives in N.B.

Hints of fall in Irishtown Nature Park, NB, 13 Sept 2020 (Dearing)

The days are getting shorter and the leaves are beginning to change colour.

Fall is here in New Brunswick with the official arrival of the autumnal equinox at 10:30 a.m. ADT.

The sun is directly above the equator and day and night are roughly equal.

The sun moves southward to the Tropic of Capricorn until the winter solstice on 21 December – the shortest day of the year.

The sun then starts moving northward again with the days gradually get longer.

Environment Canada and the Weather Network are both forecasting above normal temperatures this fall for Greater Moncton.

Frost-free season ends in Greater Moncton

A light, scattered frost appeared in Greater Moncton this morning with a chilly record-breaking low temperature of -1.3°C.

Unofficially this is a record low for 20 September and it also means the frost-free period – which on average lasts 134 days – is now over.

While 04 October is the average first fall frost date, Environment Canada notes how there’s a 33 percent chance it can occur before 21 September.

The frost-free period was much shorter in 2020 at only 102 days thanks to a late spring frost on 10 June when the thermometer dropped to -0.6°C.

UPDATE – Numerous record lows were broken early Monday morning including: -Greater Moncton broke record of -1.1°C set in 1904. -Edmundston dropped to -6.2°C which broke record of -3.0°C from 1986.

Hot & Cold in the West

High pressure allowed skies to clear and temperatures to drop across the Prairies with widespread frost in the final days of summer.

Environment Canada says record lows were set in all three provinces on 08 September.

Saskatoon sank to a bone-chilling minimum of -6.9°C, Crowsnest Pass, AB plummeted to -5.6°C and Melita, MB dropped to -3.4°C.

Meantime, the heat is on in British Columbia with daytime highs climbing into the low 30s C even along the Pacific coast.

The hot weather is combined with air quality statements about smoke for parts of the province from wildfires in the U.S. Pacific Northwest.

August 2020 – The heat continues

A stretch of warm, dry weather which started in mid-July continued through August in Greater Moncton.

Daytime highs climbed above 30°C on 11 days which is well above the average of 5 days during an entire summer.

Cooler conditions prevailed during the last few days of the month after a thunderstorm rolled through New Brunswick.

Rain was once again scarce – only two major events – which only worsened the severe drought across the region.

AVERAGE 20.2°C (about 2.0 degrees ABOVE normal)

Extreme HIGH 32.6°C (09 Aug)

Extreme LOW 6.5°C (29 Aug)

RAINFALL 42.9 mm (about 45 percent BELOW normal)

An early frost?

Environment Canada has issued a frost advisory for New Brunswick except along the Fundy coast and Grand Manan Island.

Temperatures could drop to near the freezing point in low lying areas thanks to a clear sky, light winds and a cool air mass.

This is the last day of meteorological summer, but the average first fall frost date in Greater Moncton is 04 October for a 134 day frost-free season.

The probability of frost before mid-September is only 10 percent which increases to 50 percent by month’s end.

UPDATE – No frost in Greater Moncton with low of 5.8°C but possible patchy frost up north with low of 2.0°C in Edmundston.

August heat comes to abrupt halt

A cold front crossing New Brunswick brought a strong series of thunderstorms today with watches and warnings posted for much of the province.

Greater Moncton experienced a brief but intense thundershower by early afternoon as much-needed rain fell in downpours.

The passage of this front will mark the beginning of a cooler trend which will likely last until the end of the month.

Environment Canada is forecasting highs of around 20°C over the next few days with overnight lows falling as low as 7°C – a stark difference compared to the summer so far.

Rain helps douse NW Ontario forest fire

The so-called fire, Red Lake 49, was declared under control earlier today after coming within two kilometres of the Northwestern Ontario community a few days ago.

The roughly 4,000 residents of the gold mining municipality are now allowed to return home after having been evacuated earlier in the week.

Environment Canada says a strong low pressure system brought almost 60 mm of rain to the Red Lake area with lesser amounts falling further to the south.

Although local officials say the fire did not damage any homes or businesses, some power and phone lines were impacted.

Another tornado touchdown in Manitoba

Severe thunderstorms in southwestern Manitoba produced heavy rain, quarter-sized hail, strong wind gusts – and a tornado.

Environment Canada confirmed the tornado on Friday and assigned it an EF-0 rating with winds ranging from 90-150 km/h.

The twister touched down in Alexander, just west of Brandon, shortly before 6pm Thursday, causing some minor damage but no reports of anyone injured.

Six days ago to the west, an EF-2 tornado hit the Virden area where two people were killed and another injured when their vehicles flipped over.

Winds of up to 190 km/h snapped trees, downed power lines and damaged farms.

Hot, dry summer continues

Environment Canada calls summer 2020 ‘very unusual’ in New Brunswick given the extended periods of hot, humid weather.

As of today, Greater Moncton has recorded 25 days at or above 30°C this year – extraordinary given the average is 4.6 days.

If you want to cool off, head to the much cooler Fundy coast where only one day has climbed above 30°C in Saint John.

Unfortunately for farmers and gardeners, the heat comes during an extremely dry period with below normal precipitation in every month since last December.

As of 31 July, Agriculture Canada noted how Southeast and Northwest New Brunswick along with most of Prince Edward Island are now in a severe drought.
