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.

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.
Several weather outlets are forecasting a major winter storm will hit the Maritimes bringing heavy snow and strong winds to New Brunswick just days into 2018.
Blizzard conditions are possible along with large waves and high water levels along the coast.
Nova Scotia may get more rain along the Atlantic coast while a rain/snow mix is likely inland.
Until the storm arrives, Arctic air remains firmly in place with several cities in Ontario setting new record lows on New Year’s Day including -22.6 C at Toronto Pearson Airport and -28.6 C at Ottawa Macdonald-Cartier Airport.

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.
