Autumn 2018 in review

Autumn2018
Meteorological autumn spanning the months of September, October and November proved to be cooler and much wetter than normal in Greater Moncton.

While September felt more summer-like, it turned decidedly colder by mid-October and a big drop by mid-November with a low within two degrees of a 30-year record.

Precipitation was heavy with more than 100 mm of rain falling above normal and snow first appeared in late October and again in heavy amounts by late November.

Bitter cold ahead of more snow

Temperatures sunk early Monday across the Maritimes with some New Brunswick locations shattering records by almost five degrees dating back to the 1880’s.

The bitter cold precedes another storm system which could bring up to 25 cm of snow to southern New Brunswick, most of Prince Edward Island and northern Nova Scotia.

While it plunged to -14.7°C in Greater Moncton, the 1936 record still stands at -16.7°C.

Here are some of the new record lows set in the region on 19 November:

  • Bathurst, NB -22.5°C
  • Woodstock, NB -21.4°C
  • Miramichi, NB -20.2°C
  • Kouchibouguac, NB -20.0°C
  • Summerside, PE -15.7°C
  • Charlottetown, PE -15.2°C

Early blast of winter

Southeast New Brunswick received about 20 cm of snow from a Nor’easter giving the region its first taste of winter.

Rain or ice pellets did not mix in as forecast for Greater Moncton but the snow was wet and heavy.

Higher amounts of snow fell further north and lesser amounts along the Fundy coast, Prince Edward Island and northern Nova Scotia where more rain fell.

Snowfall totals (in cm):

  • Kouchibouguac 28
  • Bouctouche 22
  • Greater Moncton 20
  • Miramichi 14
  • Fredericton 13
  • Charlottetown 9
  • Saint John 8

  • First snowfall warning for Southeast N.B.

    While other parts of New Brunswick have already had significant snow this fall, the first snowfall warning of the season has been issued for Greater Moncton and the Southeast region.

    Fresh from impacting Southern Ontario, Southern Quebec and the U.S. Northeast, Environment Canada says this storm will bring up to 15 cm of snow with ice pellets and rain mixing in before tapering off later tonight.

    Schools were cancelled in anticipation of the storm with snow beginning to fall by midmorning.

    Prince Edward Island and Cape Breton Island are expecting 15 to 20 cm with lesser amounts for mainland Nova Scotia.

    Here comes the rain (and snow) again…

    Without a doubt, it has been a soggy couple of months in Greater Moncton.

    More 100 mm of rain – almost a month’s worth – has fallen during the first week of November alone and precipitation was 50 percent above normal in October.

    Another low pressure system arrived in the Maritimes this weekend with a mix of rain and snow in New Brunswick.

    Several centimetres of snow fell in Greater Moncton and after a changeover to rain as much as 30 mm could fall before it ends later today.

    October 2018 – Cool and wet

    October 2018 proved to be very different from October 2017 in Southeast New Brunswick.

    While it was warm and dry last year in Greater Moncton (the second warmest October since 1881), it was the opposite this year – cool and wet.

    Temperatures were below normal with only one day reaching 20°C and a hard frost arrived by mid-month.

    Only seven days were dry with three major rainfall events and snow fell on three days – briefly settling on the ground twice.

    Nor’easter follows record cold

    Snow settles in NE Moncton before a changeover to rain, 28 Oct 2018 (Dearing)

    A frosty Saturday morning proved record breaking at the Greater Moncton International Airport when the thermometer plunged to -6.6°C which breaks the previous cold low from 1998 by 0.1°C.

    Frigid temperatures were also set in Edmundston at -12.2°C, Woodstock at -11.7°C and Saint John at -8.4°C with weather records going back to 1886.

    The Arctic cold was soon replaced by a low pressure system with some tropical moisture from the remnants of Hurricane Willa.

    The early season Nor’easter brought snow, ice pellets and eventually rain to the Maritimes along with gusty winds which uprooted trees in parts of New England.

    Say it isn’t snow!

    Snow settles on grass, vehicles and rooftops in NE Moncton, 25 Oct 2018 (Dearing)

    Even by New Brunswick standards, snow in October is not very common.

    But a low pressure system dropped more than 15 cm of heavy, wet snow over western and northern parts of the province creating commuter chaos in Fredericton yesterday.

    After getting drenched with 38 mm of rain, Greater Moncton received a light coating of snow this morning which stuck to rooftops, vehicles and grassy areas but it melted by midday.

    Here are some snowfall totals (in cm) from volunteer observations:

    • Charlo/Belledune area. 23 cm
    • Woodstock. 16 cm
    • Fredericton. 15 cm
    • Miramichi. 13 cm
    • Grand Falls. 10 cm
    • Moncton. 3.4 cm

    Early season snow in N.B.

    Snow has come early for parts of northern and western New Brunswick as a low pressure system brings heavy rain elsewhere in the province.

    Fredericton recorded a few centimetres of snow today while Greater Moncton is expecting mostly rain – possibly 15 to 25 mm – starting tonight.

    Environment Canada says up to 15 cm of snow could fall by Wednesday night in the north and west with greater amounts over high terrain.
