The passage of a cold front created thunderstorms across New Brunswick yesterday from west to east. 

A brief storm cell moved through Greater Moncton late in the afternoon with ominous clouds and a short downpour. 

The cold front has been replaced by cooler, drier air today with a seasonable high of 22 C today in Southeast New Brunswick.

Summer officially arrived in New Brunswick today at 1:24am. 

This is the longest day of the year at 15 hours and 46 minutes in Greater Moncton. 

The sun has reached its northernmost point over the Tropic of Cancer and now begins moving southward which will gradually shorten days. 

The solstice is celebrated in Stonehenge, England where the U.K. Met Office says a record high today of 32.3 C near Gatwick Airport is the warmest first day of summer ever.

In Greater Moncton, the temperature fell to a new record low of -7.7 C which beat the old minimum of -7.2 C from 1961. 

In Nova Scotia, Halifax Stanfield Airport set a new low of -8.0 C while Parrsboro dropped to -9.3 C. 

Charlottetown, Prince Edward Island recorded a new low of -8.9 C which broke the old low of -7.7 C from 1977. 

Newfoundland records could be described as frigid with new minimums in Deer Lake at -20.3 C beating a low of -12.3 C from 2015 and Corner Brook fell to -14.9 C which broke the old record of -8.8 C also from 2015. 

Greater Moncton hard hit by ice storm

More than seven hours of freezing precipitation (ice pellets and freezing rain) weighed down trees and power lines in Southeast New Brunswick causing tens of thousands of power outages.

At the peak, NB Power reported more than 130,000 customers without electricity and the majority were concentrated in Greater Moncton.

The provincial power utility described the ice storm as a “major weather event” and dispatched at least 60 additional crews to restore the grid.

Environment Canada says at least 30 mm of freezing precipitation was recorded in the region and up to 15 mm of rain could fall today.

Above freezing temperatures are expected to melt much of the ice during daylight hours.

Matthew finally weakens

The U.S. National Hurricane Center finally downgraded Matthew to a post-tropical cyclone today after pounding North and South Carolina with strong winds, heavy rain and record flooding before moving east out to sea.

Matthew made landfall near Charleston, South Carolina yesterday as a category 1 hurricane after hugging Florida’s Atlantic coast.

Hundreds had to be rescued from floodwaters in the Carolinas including one woman who was forced to cling to a tree overnight before emergency workers arrived.

The most powerful Atlantic storm in a decade has claimed at least 20 deaths in the Southeastern United States and more than 900 in the Caribbean, mostly in Haiti.

Latest round of snow to miss NB

An early spring snowstorm blanketed Southern Ontario yesterday with Toronto Pearson Airport picking up 13 cm and Hamilton getting 18 cm.

The same Alberta Clipper moved over to the American Northeast today giving Boston a wintry feel again.

The system will brush the Atlantic coast of Nova Scotia with about 5 cm of snow and lesser amounts inland.

New Brunswick will be spared this round but we won’t escape the cold with overnight lows dipping to -12 C in Greater Moncton.

Almost April Fool’s record high

It was no joke that Greater Moncton almost reached a record high on the first day of April.

Environment Canada says the record is 18.5 C from 2006 and the official high today was 16.6 C.

The last time it was that warm was last fall –  29 October.

A southerly air flow is a far cry from the colder than normal temperatures in late March.
