Temperature dropped below 10 C by early afternoon, 02 June 2018 (Dearing)
Unbelievable! Conditions went from hot to cold in just a matter of hours after a cold front swept through New Brunswick today.
In Greater Moncton, the high of 18°C was set early this morning before the front changed the wind direction from south to north and the temperature dropped six degrees in an hour to 11°C by 9am.
This is in stark contrast to yesterday when the thermometer climbed to 29.7°C which was the warmest high so far this year.
New maximum records were set for 01 June in Bouctouche at 32.6°C, Miramichi at 32.7°C and 33.2°C at Kouchibouguac National Park.
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.
Given the recent stretch of below seasonal temperatures in Southeast New Brunswick, I wasn’t optimistic we would reach 20 C anytime soon.
But yesterday the thermometer climbed to 21.2 C in Greater Moncton marking the first time to reach and surpass that threshold in 2018.
Over the last five years, we have reached 20 C over a two week period from mid-April to early May.

Warm spring-like sunshine could be felt on my western facing balcony this afternoon in northeast Moncton and for few precious minutes it almost felt like winter was over.
The thermometer climbed to 12.9 C at the Greater Moncton International Airport which just barely eclipsed the record high of 12.8 C from 1953.
Other record highs were set across the Maritimes including 13.8 C in Cheticamp, Nova Scotia and 10.4 C in Edmundston.
But further to the west, the temperature climbed to a balmy 17.6 C in Sherbrooke, Quebec.

Environment Canada issued a flash freeze warning for much of New Brunswick, Nova Scotia and Prince Edward Island early today.
A low pressure system brought snow, later rain and then snow again after the temperature plummeted as Arctic air pushed back into the region.
The daytime high in Greater Moncton was 3.0 C at 11am and pooling water began freezing when the thermometer dropped below freezing by 3pm.
By early Saturday, forecasters say the low could drop to -20 C but temperatures will moderate on Sunday before falling again on Monday.

The first month of 2018 proved to be quite a roller coaster ride in Southeast New Brunswick.
Bitter cold to begin January was briefly erased by a fast-moving ‘bomb cyclone’ until another Arctic blast sunk the low to -22.3 C with a bitter wind chill of -36.
A record thaw saw the thermometer climb to 16.7 C in Greater Moncton – the highest ever in January – and a new all-time provincial high of 17.3 C in Sussex.
Precipitation was above average overall with near normal snowfall – 25 cm was the heaviest snow event on 30-31 – and about twice as much rainfall.

After a low pressure system brought heavy rain and strong winds gusting up to 74 km/h to Southeast New Brunswick early today, a cold front moved through the region plummeting temperatures below freezing.
The thermometer in Greater Moncton dropped an incredible 14 degrees in just one hour – from 15 C at 11am to 1 C at noon – and then fell below zero shortly afterward.
Today’s daytime high of 16.7 C has unofficially broken the 13 January record of 12.2 C from 1972.

Flooding was reported in various parts of Greater Moncton and the province was forced to close some roads due to high water levels.

A recent heat wave in Australia was so severe that asphalt melted on some highways, firefighters had to battle wildfires and bats fell out of trees after literally boiling to death.
The daytime high reached a scorching 47.3 C in a western suburb of Sydney on Sunday which was the hottest since 1939 and while Melbourne was cooler, the thermometer still climbed to 40 C.
Beaches were so crowded in Sydney, there was virtually no room to move around.
While it is the height of summer Down Under, the normal January high in the New South Wales capital city is 27 C with an overnight low of 20 C.
Snow is piled high in Boston, MA, USA, 05 Jan 2018 (AP)
Much of New Brunswick was under another extreme cold warning this weekend with a near record low of -22.3 C in Greater Moncton today (record is -23.3 C from 1945) and a bone-chilling wind chill near -36.
Environment Canada is calling for temperatures to moderate this week with a return to near normal values and even above freezing temperatures by Thursday.
The Northeast United States has also been under a cold snap and the thermometer bottomed out Sunday with record lows in a number of cities including Burlington, Vermont at -29 C and Portland, Maine at -24 C.
Boston, Massachusetts tied its record low of -19 C just days after digging out from 34 cm of snow during the ‘bomb cyclone’ and being inundated with icy floodwaters from the highest tides in a century.
A sunny but cold morning in west end Moncton, 13 Nov 2017 (Dearing)
Clear skies and an Arctic air mass lowered temperatures in Greater Moncton to a chilly -9.0 C on November 12th and 13th.
Recent data shows temperatures that low (within 2 and 3 degrees of record lows) typically don’t occur until later in the month and the thermometer failed to climb above freezing on the 12th which is also earlier than normal.
A new record low was set at the Saint John Airport when it fell to -11.3 C on the 12th.
Quite a contrast from just a week ago when several communities in New Brunswick climbed into the low 20s Celsius.
