Return to winter

A strong low pressure system is expected to bring a lot of snow, some rain and wind to Southeast New Brunswick starting Thursday night.

About 15 cm could fall in Greater Moncton prompting Environment Canada to issue a snowfall warning.

Strong winds will coincide with high tide along the Northumberland Strait creating storm surge.

This could be the heaviest snowfall event since 01 March when 14 cm fell.

Warm spring day

Finally some warmth!

Southeast New Brunswick is trending slightly above normal for March but real heat has been absent until this weekend.

Greater Moncton reached 9.4°C which was a monthly high.

Liverpool, Nova Scotia hit 13.9°C while Saint John recorded 10.5°C.

Remember the Great March Heat Wave?

Early spring is not known as being particularly warm in New Brunswick, but the early days of spring in March 2012 were a rare exception.

For three consecutive days, the thermometer soared into the 20’s Celsius in Southeast New Brunswick breaking record highs and culminating in an unbelievable all-time monthly maximum of 26.1°C on 22 March 2012.

Beachgoers flocked to the coast to take advantage of the summer-like conditions and some at Parlee Beach even took a dip in the Northumberland Strait despite ice patches still floating in the water.

Although temperatures have been near normal so far this month, Greater Moncton has yet to crack 10°C.

Spring arrives

The spring or vernal equinox arrived at 12:50am ADT in New Brunswick which marks the moment when the Sun is directly above the equator as it continues to move northward.

Days are now about equal in length to nights and the amount of daylight will continue to increase until the first day of summer in June.

Spring may be here officially but consistent warmth is usually delayed in the Maritimes thanks to the surrounding cold ocean waters.

So far this March in Greater Moncton, temperatures have been close to normal overall but precipitation has been well below average.

Warm front brings record highs

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

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