Thunderstorm activity was common throughout Southeast New Brunswick in June and all but ten days had at least a trace of rainfall.

But precipitation amounts were generally light in Greater Moncton except for two major rain events – 36.6 mm fell on 09 June along with a peak wind gust of 102 km/h and 21.2 mm fell on 24 June.

Temperatures were cool during the first week of the month with an overnight low dropping to the freezing point although frost was generally avoided thanks to cloudy skies.

Summer-like conditions arrived by mid-month and many daytime highs climbed well into the 20’s C and reached 30 C or higher three times.

Warmer weather ushers out cold

At least one New Brunswick location dropped to a new low on 06 June.

Environment Canada says Kouchibouguac National Park set a new cold record of -1.7 C which broke the old minimum of -1.1 C from 1958.

Greater Moncton managed to escape frost this week thanks to cloud cover although the thermometer fell to the freezing point tying a record low.

Following a brief period of very warm air, forecasters say temperatures will reach near seasonal values for the short term.

Near record cold in N.B.

The last couple of days had near record lows in Greater Moncton with temperatures dropping to near the freezing point.

A low of 1.0 C at the airport on Monday was close to the 1947 record of 0.6 C while a low of 0.0 C on Tuesday tied the minimum from 1995.

Fortunately cloud cover prevented frost in most of New Brunswick but another risk is possible by early Wednesday.

Folklore suggests frost can be expected until the full moon in June which is this Friday the ninth.

Winter returns to the U.K.

Snow covers a vehicle in Aviemore, Scotland, UK, 25 April 2017 (BBC Weather)


Arctic air has enveloped the United Kingdom with heavy snow in Scotland and northern England and near freezing temperatures as far south as London.

Forecasters say snow in late April is not uncommon and actually fell over parts of the country around the same time last year.

Temperatures struggled to reach 10 C today after a hard frost early this morning.

This cold snap is a far cry from record breaking heat earlier this month when the thermometer climbed to 26 C in southern England and a mild March which was the fifth warmest ever for the U.K.

October 2014 – Warm and relatively wet

October 2014 definitely proved to be warmer than normal in Greater Moncton with the monthly temperature about 2.1°C above the 30-year average.

Generally speaking the month was mostly dry except for three rain events on 08 Oct, 17 Oct and an extended wet period thanks to a slow moving Nor’easter from 22-26 October.

The temperature fell below freezing only once at -1.1°C on 21 Oct which produced a light freeze but not a killing frost and not a single snowflake was recorded during the month.

For the first time since late May, the thermometer dropped below the freezing point in Greater Moncton this morning to -1.1 C.

Frost was widespread although hardier vegetation appears to have been spared.

For 2014, this means Greater Moncton had above freezing temperatures for 144 days which is slightly longer than the average growing season.

Precipitation remains below normal so far this autumn but that could change with Environment Canada predicting 50-100 mm of rain across New Brunswick over the next few days.
