Thunderstorm moves into Saint John, 12 June 2017 (AKS/Twitter)
After three days of daytime highs above 28 C in Greater Moncton, much cooler weather is coming thanks to a cold front and a change in wind direction.
The warm sometimes unstable air mass has created severe thunderstorms across the region.
Flash flooding was reported in Saint John yesterday after heavy downpours with wind and and hail which were also observed today in northeastern Nova Scotia.
Environment Canada is forecasting below seasonal temperatures for Southeast New Brunswick over the next couple of days.

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.

Forecasters say warmer, more seasonal temperatures will return by Wednesday but not before a risk of frost in Southeast New Brunswick by early Tuesday.

Parts of Cape Breton Island were flooded by a deluge of rain barely six months ago – Thanksgiving weekend – and this week it’s happening again.
The ground is saturated with water after more than 160 mm of rain since the weekend and some Sydney residents are dealing with flooded basements.
Rain and snow melt from the Cape Breton highlands is being blamed for washouts along sections of the Cabot Trail and its side roads.
Road crews are working overtime making repairs before the busy tourism season begins in a few weeks.

After a stormy, rollercoaster winter in Southeast New Brunswick, spring will be especially welcomed today at 7:28am ADT.
The vernal or spring equinox is when the sun’s direct rays move north of the equator from the southern to the northern hemisphere.
At this time, the length of day and night are about equal and days will continue to lengthen until the summer solstice in June.
But winter is not over yet as Environment Canada says a low pressure system will bring snow to Nova Scotia and the possibility of freezing rain for Greater Moncton.

An intense low pressure system tracked across the Maritimes today bringing heavy snow along with strong northerly winds creating blowing and drifting snow.
Environment Canada says this was the fourth storm system to impact Greater Moncton and Southeast New Brunswick over the last two weeks.
Visibility was often very poor and the New Brunswick Emergency Measures Organization restricted travel to snow plows and emergency vehicles on many major highways today.
