Heavy rain during thunderstorm in NE Moncton, 21 July 2017 (Dearing)
The temperature climbed to 30 C for three days in a row in Greater Moncton which is an unofficial heat wave since 32 C is the maximum by definition.
Those warm daytime highs, 30.4 C (19 July), 30.4 C (20 July) and 30.0 C (21 July), still haven’t eclipsed the season-to-date maximum of 30.8 C recorded on 11 June.
A cold front moved west to east through New Brunswick yesterday triggering scattered thunderstorms with heavy rain, gusty winds and even hail.
The heat and humidity have been replaced by a cooler, drier air mass with highs in the low 20’s C which is slightly below normal for late July.

An unstable air mass moved from west to east in New Brunswick producing severe thunderstorms bringing torrential rain, large hail and strong winds.
Environment Canada believes a severe thunderstorm formed near Doaktown and possibly spawned a tornado that moved into the Blackville area last night.
Golf ball size hail and damaging winds with gusts up to 100 km/h were recorded in the Plaster Rock area.
Southeast New Brunswick has seen an above average 18 days with thunderstorm activity this June and a severe thunderstorm watch was issued in the region this afternoon.

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 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.

Environment Canada says a warm, moist air mass that has been responsible for high humidity and severe thunderstorms across New Brunswick is finally moving out of the province.
The storms would often develop in the late afternoon or early evening and produce strong winds, heavy rains, brief localized flooding and even hail in some areas.
Drier and cooler air has moved into the province which is expected to bring near or slightly below temperatures to Greater Moncton with little chance of precipitation.
As you can see above, a double rainbow was spotted over Riverview last night after a brief storm.
According to Accuweather, while a primary rainbow is visible when light is reflected once off the back of a raindrop, a secondary and usually dimmer rainbow is spotted when light is reflected twice in a more complicated pattern.

Hundreds of lightning strikes and winds gusting up to 82 km/h brought branches and trees down on power lines with up to 10,000 outages reported at the storm’s peak.
