January 2020 – Warmer than normal

Glancing at the data for January 2020, one would think it was as cold if not colder than normal in Southeast New Brunswick.

The thermometer sank below -10°C on sixteen days while four of those days dropped to -20°C or lower during the month.

Despite the frigid weather, January was in fact almost three degrees above normal in Greater Moncton.

Despite two major snowfalls (including one event near 30 cm) and some rainfall, precipitation was close to the thirty-year average.

Hours of ice pellets!

Back-to-back low pressure systems brought a messy mix of precipitation to much of the Maritimes over the weekend.

Rain began falling Saturday with a near record warm high of 11 C in Greater Moncton which melted any snow on the ground.

However, the next system brought colder temperatures and more than ten hours of ice pellets (sleet) in Southeast New Brunswick sometimes mixed with snow and freezing rain.

About 15 cm of ice pellets and snow accumulated Sunday which forecasters say is quite rare and it was certainly heavy to move.

Mild but stormy conditions

Another intense low pressure system moved through the Maritimes on the weekend bringing a new round of heavy rain and strong winds.

After a bone-chilling start, winds changed direction and a southerly flow pushed the high in Greater Moncton to 13.8°C – close to the record of 13.9°C from 2008.

Winds were strong with gusts up to 87 km/h in Southeast New Brunswick and a peak of 91 km/h reported in Bathurst.

As the storm headed to Newfoundland, cold air plunged into the region and temperatures fell below freezing and may stay that way for several days.

Sharp drop in temperature!

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.

Windy start to November

Blustery but mild weather on Halloween continued throughout the first day of November in Southeast New Brunswick.

A cold front created strong winds with a sustained high of 64 km/h and a peak gust of 94 km/h at the Greater Moncton Airport.

Many trees and branches – already weakened by Dorian earlier this fall – came down onto power lines with NB Power dealing with almost 60,000 customers without electricity by late Friday.

Environment Canada warned of gusts up to 110 km/h in the Tantramar Marsh which forced the shutdown of the Trans Canada Highway between Amherst and Sackville until winds subsided.

The daytime high on 01 November was 19.4°C which was slightly warmer than the October maximum of 19.3°C.

The same storm system also hit Quebec where more than one million customers lost power, one man was killed by a falling tree and a canopy collapsed at a service station.

October 2019 – Gradual easing into fall

Daytime highs were consistently in the mid-teens in Southeast New Brunswick during October which usually sees a sharp drop in temperature as the month progresses.

The average temperature was 0.7°C above normal in Greater Moncton with two days failing to reach 10°C and the warmest maximum on the last day, 19.3°C.

Six days had lows below freezing with some light frost but there was no hard freeze allowing vegetation to flourish.

The precipitation total mostly came from five rainfall events with not a single snowflake recorded.

Fall foliage peaked prior to Thanksgiving weekend and several strong wind events left few leaves on trees by Halloween night.

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.

Warmth returns!

Irishtown Nature Park, 05 October 2019 (Dearing)

Barely a day after the coolest daytime high in five months, temperatures climbed into the high teens in New Brunswick and low 20’s in Nova Scotia.

This proves just how changeable October can be.

Greater Moncton has wrapped a third day at around 17°C.

The maximum October temperature is typically at least 20°C and it is still possible to reach it before the end of the month.

Autumn arrives!

Summer it seems we hardly knew ya!

Fall officially arrived early this morning in New Brunswick with the autumnal equinox at 4:50am ADT.

The sun is now located just above the equator and day and night are about equal.

The nights will continue to get longer throughout autumn.

The first day proved summer-like in Greater Moncton with a daytime high of 25.8°C and a humidex of 32.
