Sharp drop in temperature!

Temperature contrast 8pm, 12 Nov 2019 (earth nullschool.net)

Snow began falling in Southeast New Brunswick Monday night and later changed to freezing rain and then rain by Tuesday afternoon.

The temperature climbed to a balmy 14°C in Greater Moncton and 18°C in Greenwood, Nova Scotia.

But as the low pressure system moved out of the Maritimes toward Newfoundland, winds shifted to the northwest causing the thermometer to drop rapidly Tuesday night with a return to snow when it fell to freezing again.

Overnight low records could be challenged in the region by early Thursday as cold Arctic air takes hold.

Heavy, wet snow creates chaos

Some drivers were prepared when snow entered the forecast for the first time this week and had their winter tires installed.

But many drivers were caught off guard by the heavy, wet – sloppy – snow which fell across Southern New Brunswick, Prince Edward Island, northern Nova Scotia and southwestern Newfoundland.

A low pressure system brought rain on Thursday but snow fell by evening as the temperature dropped to the freezing point.

The snow continued throughout Friday creating slippery roads which left plow operators scrambling to deal with the early blast of winter.

Many minor accidents were reported with vehicles sliding into the ditch.

The Trans Canada Highway at Cobequid Pass was forced to close for several hours Friday night after numerous tractor trailers got stuck in snow and blocked the road.

Snowfall amounts (Thu-Fri) in cm:

  • Corner Brook 19.4
  • Greater Moncton 18.8
  • Fredericton 10-15 (estimate)
  • Deer Lake 13
  • Saint John 8.9
  • Halifax Stanfield 5.8
  • Charlottetown 3.9

First snow of the season

Snow
A low pressure system moving through the Maritimes brought the first snow of the season to Southeast New Brunswick today.

A cold rain eventually turned to snow in Greater Moncton and 7.2 cm fell with Environment Canada calling for up to 10 cm tomorrow.

As the above chart shows, the first measurable snow in the region is typically recorded from late October to late November.

Tire shops have reportedly been busy this week as drivers scramble to get their snow tires installed.

A Blustery Halloween!

Fewer trick or treaters are expected to be spooking neighbourhoods in Greater Moncton thanks to heavy rain and strong winds.

A low pressure system could bring at least 30 mm of rain to Southeast New Brunswick over the next 24 hours.

Potentially hurricane-strength winds are expected tomorrow ahead of a cold front but temperatures will be warm reaching the high teens.

Environment Canada has issued wind warnings with gusts from 60-90 km/h and possibly up to 110 km/h in the Tantramar Marsh.

Forecasters say the wind may cause damage to buildings such as to roof shingles and windows.

The wind may not die down until early Saturday.

More rain & wind for Maritimes

Another low pressure system moved through the Maritimes on Wednesday bringing a lot of rain to the region especially to western New Brunswick.

Winds were also a factor with this storm but for a shorter period of time even though the peak gust was 81 km/h which was slightly higher than last week.

Here some rainfall totals (mm):

  • Saint John  59
  • Edmundston  59
  • Bathurst  49
  • Fredericton  48
  • Miramichi  37
  • Sydney  30

Fast and furious storm

A so-called bomb cyclone with wind and rain moved through the Maritimes in just a few hours today.

The intense low pressure system brought winds gusting up to 89 km/h in Saint John which uprooted some trees already weakened by Hurricane Dorian last month.

Greater Moncton recorded a peak gust of 78 km/h along with 20 mm of rain which caused some localized flooding as leaves clogged storm drains.

The winds were even stronger in Nova Scotia with a gust of 101 km/h at Halifax harbour and 106 km/h in Lunenburg which brought trees down knocking out power.

The highest gust was near Cheticamp on Cape Breton Island at 148 km/h.

Rainfall amounts across New Brunswick and Prince Edward Island ranged from 15 to 30 mm with more than double those amounts in Nova Scotia.

Strong fall storm coming

An intense low pressure system is heading to the Maritimes.

Heavy rain will start during the morning hours in Greater Moncton and strong winds will develop by midday.

Environment Canada says rainfall amounts could reach 50 mm while easterly wind gusts of 70 km/h or higher are likely.

Some trees may be at risk of falling after being weakened by Hurricane Dorian last month.

Many leaves will undoubtedly drop which could plug storm drains causing localized flooding.

September snow in the West!

Autumn began just a few days ago but it already looks and feels like winter in parts of British Columbia, Alberta and Saskatchewan.

A strong low pressure system prompted snowfall and winter storm warnings as up to 100 cm of snow fell across southern Alberta.

Gusty winds behind the system created blowing and drifting snow making highway travel treacherous.

Many early season snowfall records have been broken.

Snowfall amounts (in cm) as of 1pm MDT, 30 September:

  • Calgary 32
  • Claresholm  40-45
  • Lethbridge  50-60
  • Taber  60
  • Cardston area  70-90
  • Waterton Park  95

Erin drenches Maritimes

Post-tropical depression Erin interacted with an incoming low pressure system to produce lots of rain in the Maritimes.

Environment Canada says the heaviest amounts were recorded in northern Nova Scotia and the Annapolis Valley – Parrsboro and Greenwood each had more rain from this storm than all of July and August combined.

Some roads were damaged and even washed out by surface runoff or flooding.

Erin’s direct path along Nova Scotia’s south shore produced wind gusts up to 80 km/h.

The storm brought tropical air with a high of 23°C in Greater Moncton on Friday but a humidex of 32.

Rainfall totals (mm):

  • Parrsboro 162
  • Greenwood 127
  • Kentville 115
  • Summerside 67
  • Fredericton 56
  • Moncton 50
  • Halifax (city) 48
