October 2010 – Wet and mild

Halloween in Moncton

October in Greater Moncton proved to be a continuation of September with mild temperatures and wet conditions with more than 45 mm of rain falling on the 2nd alone.

The warmest weather was during the first few days of the month with an overnight low of 21.2 C on the 1st which was the warmest low so far of 2010.

The fall foliage season was longer and more brilliant than past years with many trees holding on to most of their leaves until the last week of the month.

A cold snap on Halloween weekend brought the first snow flurries of the season to the region.

Weather Bomb!

Intense fall storm over Great Lakes, 26 Oct 10

An intense autumn storm, known as a “weather bomb” (a low-pressure system that develops rapidly), has blown across the Prairies and Midwestern U.S. and has moved into Ontario.

As much as 20 cm of snow and winds gusting to 80 km/h impacted parts of Saskatchewan.

Winds were also a problem in Ontario with gusts of 100 km/h reported in Sudbury and gales strong enough to blow transport trucks off the road near Chatham.

Forecasters say the storm was a little stronger than the one that sank the Edmund Fitzgerald, a freighter, to the bottom of Lake Superior in 1975.

Southern Ontario snow

Snow in Barrie, ON, 22 Oct 10

Snow may be early for Southern Ontario but not that unusual for late October especially in the snow belt regions.

Environment Canada issued a special weather statement indicating that wet flurries were possible east of Lake Huron to Waterloo and north to Barrie.

Still, snowflakes were also falling as far south as Markham, just east of Toronto.

Snowshowers were also reported at Toronto’s Buttonville Airport.

Hurricane season not over yet

The 2010 hurricane season still has a little over a month to go before it is officially over – ending November 30 – and forecasters say more action is yet to come.

Two major hurricanes, Earl and Igor, both had a devastating impact on Atlantic Canada.

Hurricane Earl slammed into SW Nova Scotia on September 4, bringing powerful winds, heavy rain and knocking down hundreds of trees leaving thousands without power.

On September 21, a massive hurricane named Igor sideswiped Newfoundland, bringing unprecedented damage to the province.

Roads were swept away, entire communities flooded and thousands had no electricity for days.

Fall foliage reaches peak

Boyd Mountain near Elgin, NB, 17 Oct 10

The fall foliage has reached its peak in Southeastern New Brunswick. 

The colours were never as brilliant as they were this weekend as I discovered during a tour of Albert County and a trip from Riverview to Elgin.

The above picture was taken on Boyd Mountain near the village of Elgin.

The peak colours were about 10 days later than usual this fall due to the prolonged warm weather and the lateness of the first killing frost of the season.

Nor’easter on the way

Greater Moncton and the rest of Atlantic Canada are bracing for the first Nor’easter of the season – this one bringing heavy rains and high winds.

Anywhere from 20 – 50 mm of rain is expected to fall in the Maritimes on today and winds could be gusting up to 100 km/h.

A Nor’easter is a relatively strong coastal storm with three ingredients: cold clashing with warm, a good source of moisture and a strong jet stream disturbance.

Depending on the season and temperature, a Nor’easter can bring rain, freezing rain, snow, ice pellets and even thunderstorms if enough warm air is in place.

UPDATE – Greater Moncton reached almost 30 mm of rain during the storm and wind gusts up to 70 km/h.

Killing frost!

Greater Moncton had its first killing frost of the season this morning when the temperature dipped to a chilly -1.8 C.

This was the third morning in a row for frost although today was the most severe and enough to kill tender plants.

This was also the first time since May 13 when the thermometer dipped below the freezing mark in Greater Moncton.

First frost warning of fall

It had to happen sooner or later and it looks like frost could finally strike overnight according to Environment Canada:

Monday 11 October 2010
Frost warning for Moncton and Southeast New Brunswick

This is a warning that at or near zero ground temperatures will cause frost in parts of these regions.

On average the first frost of fall in Moncton is Sept. 27, so we have been pushing the envelope this year.

Temperatures have dipped as low as 0.8 C but cloud cover and winds have prevented frost from occurring to date.

Thanksgiving heat on Prairies

Omega pattern in jet stream keeps west mild

A ridge in the jet stream has made this Thanksgiving weekend feel more like summer in the Prairie provinces with temperatures in the low- to mid-20’s.

Some places climbed even higher, like Drumheller, Alberta, which hit 29°C on Sunday – the hottest spot in Canada.

On Saturday, the hot spot was in Brandon, Manitoba, at 25.8°C.

It was the warmest October 10 ever in places like Edmonton (24°C), Lloydminster, Alberta (23°C), and Prince Albert, Saskatchewan (22°C).
