Teddy proves to be tepid

Nova Scotians breathed a sigh of relief today as Post-Tropical Storm Teddy packed a bigger bark than a bite.

The Canadian Hurricane Centre says the expansive storm made landfall near Ecum Secum, along the eastern shore of Nova Scotia, around 8 a.m. ADT with heavy rain and winds up to 105 km/h.

Large destructive waves were hazardous along the Atlantic coast and authorities urged storm watchers to stay home for their own safety.

Teddy quickly moved over Nova Scotia into the Gulf of St. Lawrence on its way to western Newfoundland.

A rainfall warning was issued for Southeast New Brunswick with Greater Moncton getting about 30 mm of rain and a peak wind gust of 80 km/h.

Autumn arrives in N.B.

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.

Fall sneak preview

For the first time since mid-July, the daytime high in Greater Moncton didn’t reach 20°C.

On Friday, the daily maximum was 15.5°C which is also about five degrees below normal for mid-September.

The fall-like weather arrived after a cold front moved across New Brunswick replacing warm, humid air with cooler, drier conditions.

This morning’s chilly low of 4.0°C was the coldest since 10 June when the temperature fell slightly below freezing – enough for a light frost.

While some parts of the province had scattered frost, my neighbourhood and my tomatoes were spared.

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.

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.

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.

July 2020 – Warm & dry

Warm summer-like weather continued throughout July after finally getting started in mid-June across New Brunswick.

Several heat warnings were issued with daytime highs reaching 30°C or more on eight days – the normal is two.

The overall average may have been even higher for Greater Moncton had it not been for cool overnight lows early in the month.

July 2020 still falls a bit short of the very warm July 2018 which reached 21.4°C.

The drought worsened and although rainfall was higher compared to June it was still 25 percent below normal.

AVERAGE 20.3°C (about 1.6 degrees ABOVE normal)

Extreme HIGH 32.0°C (20 July)
