Here comes the rain (and snow) again…

Snow settles in NE Moncton before changeover to rain, 10 Nov 2018 (Dearing)

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.

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.

Leslie responsible for rain

Hurricane Leslie is churning well south of the Maritimes and is not forecast to impact the region directly but the storm is indirectly responsible for heavy rain.

The sheer size of the storm – Leslie is more than 1,000 km wide – caused a low pressure system to stall bringing lots of rain to Nova Scotia, New Brunswick and Prince Edward Island.

Here are some totals from the rain event:

  • Greater Moncton. 32.6 mm
  • Saint John. 46.7 mm
  • Charlottetown. 47.2 mm
  • Halifax Stanfield Airport. 24.7 mm
  • Yarmouth. 43.2 mm

  • September 2018 – Warm and wet

    Warm, summer weather picked up in September where it left off in August in Southeast New Brunswick.

    But the passage of a cold front marked a drastic temperature drop on the 18th and suddenly it felt like fall in Greater Moncton.

    The thermometer continued to plunge and sank to -1.9°C on the 25th with light, scattered frost although most vegetation was spared severe damage.

    Precipitation was actually above normal although heavy amounts fell in a handful of rainfalls.

    A good soaking!

    An intense low pressure system from the Great Lakes moved across New Brunswick Wednesday night and brought heavy rain especially along the Fundy Coast.

    Alma at the entrance of Fundy National Park recorded 121 mm which is more than a month’s worth of rain in just 24 hours.

    While it was a deluge for some, it was definitely much needed precipitation.

    Here are more rainfall amounts:

    • Harvey, NB. 80 mm
    • Yarmouth, NS. 75 mm
    • Saint John, NB. 55 m
    • Halifax Airport, NS. 28 mm
    • Greater Moncton. 24 mm

    July 2018 – Record heat!

    Five Islands, Colchester County, NS, 24 July 2018 (Dearing)

    July was definitely hot and often humid in Greater Moncton with Environment Canada confirming it was the warmest since 1940.

    The average daily temperature was 21.4 C which is 2.6 degrees above normal.

    An official heat wave in the first week was followed by numerous heat warnings being issued.

    The thermometer climbed to 30 C or higher on 11 days during July and never dropped below 18 C during 7 overnights.

    Rainfall was more than 30 percent below normal and much of the precipitation fell during thunderstorms.

    June 2018 – Cold nights, plenty of rain


    Ogilvie Brook, Irishtown Nature Park, 24 June 2018 (Dearing)

    Greater Moncton has endured the coolest June in recent memory and while daytime highs were close to normal – with a few exceptions – overnight lows were cold, even frosty at times during the first half of the month.

    A hard frost on 04 June with a record breaking low of -3.2 C was devastating for agriculture across New Brunswick especially in the Southeast.

    Farmers suffered major damage – in some cases 50 to 80 percent losses – to crops such as grapes, strawberries and blueberries.

    Oddly enough, the temperature had not been that low in all of May and not since 16 April had it been at least that cold.

    Rainfall was about 60 percent above normal and was confined to a handful of major rain events with nine days being completely dry.

    JUNE 2018 ALMANAC (at Greater Moncton Int’l Airport, 1981-2010)

    Average HIGH  20.3°C

    Average LOW  6.6°C

    AVERAGE  13.5°C (about 1.7 degrees BELOW normal)

    Extreme HIGH  29.7°C (01 June)

    Extreme LOW  -3.2°C (04 June)

    RAINFALL  154.0 mm (about 60 percent ABOVE normal)

    TWN unveils summer forecast

    Spring has sputtered in New Brunswick – it was nowhere to be found in March, finally appeared in late April and although May has had a few warm days, the month is still running slightly below normal in Greater Moncton.

    So what about summer?

    In its seasonal forecast, the Weather Network believes a cool June should give way to more consistent warm weather during July and August.

    A humid summer is expected which may result in warmer than normal temperatures at night – overnight lows average about 12 C.

    While periods of dry weather are expected, heavy showers and thunderstorms should bring rain totals to near normal for the season.

    Snow in late May!!!

    While a snowflake or two is common in early May in New Brunswick, accumulating snow is rare in the latter part of the month.

    A cold front pushed through the province today and with a change in wind direction from south to north, precipitation changed from rain to snow and the thermometer plummeted.

    Bathurst and Miramichi both reported snow today and in some areas it began to stick to the ground while thunderstorms rolled through further south.

    In Greater Moncton, the temperature drop was dramatic with a high of 16 C at 11am and by 4pm it was only 5 C.

    Meantime, parts of central Newfoundland are under a snowfall warning with 15 to 30 cm in the forecast.

    Icy weekend in Central Canada

    A slow moving low pressure system brought a wintry mix of snow, ice pellets, freezing rain, rain and strong winds to Southern Ontario and Southern Quebec over the weekend.

    Icy conditions led to more than 1,600 highway crashes, numerous power outages from falling trees and downed lines, cancelled flights, transit delays and school closures.

    Officials were forced to close the CN Tower due to falling ice from the structure.

    Here are some totals from the spring storm as of 16 April at 2pm EDT:

    • Toronto Pearson Airport – 18 hours of ice pellets, 6 hours of freezing rain, 12 cm ice pellets.
    • Toronto Billy Bishop Airport – Peak wind gust of 96km/h
    • London – 14 hours of freezing rain with ice pellets
    • Windsor – 6 hours of freezing rain
    • Hamilton – 11 hours of ice pellets, 6 hours of freezing rain and ice pellets, 8 hours of freezing rain
    • Ottawa – 9 hours of freezing rain Sunday, 6 hours of freezing rain Monday, wind gusts to 70 km/h
    • Montreal – 9 hours of freezing rain Saturday, 4 hours of freezing rain Sunday, 3 hours freezing rain Monday
    • Quebec City – 5 hours of freezing rain Monday
