Heat wave in the West

Environment Canada issued heat warnings for most of Alberta along with parts of Saskatchewan and Manitoba this week in the wake of sizzling high temperatures.

The weather office says a daytime maximum of 30 C or higher could pose an elevated risk of heat-related illnesses and residents should avoid outdoor activities until cooler hours of the day.

Temperatures could climb to 33 C as far north as Thompson and almost 30 C in Churchill along the Hudson Bay coast.

Forecasters say the extreme heat will continue this weekend but a slight cool down is expected early next week.

Dry July in Southeast N.B.

Lawns are turning brown and gardens are thirsty in Southeast New Brunswick given the light amount of precipitation recorded so far this month.

Environment Canada says 29.8 mm of rain has fallen this July in Greater Moncton compared to an average of 92.1 mm – just under one-third of normal.

No significant rainfall is expected before the end of the month.

By contrast, parts of neighbouring Nova Scotia have been much wetter than normal with 135 mm to date at Halifax Stanfield Airport.

 

Decent first half of July

For whatever reason, summer seems to go by faster than the other seasons and here we are already at the midway point of July. 

After 16 days, Greater Moncton has been having a decent month with an average temperature of 19.3 C which is 0.5 degrees above normal. 

Daytime highs have been warm but not hot with a peak of 29.4 C on 16 July while overnight lows have been mild except for a chilly low of 8.9 C on  05 July. 

The only concern is a lack of rainfall. 

The tally is 19.8 mm so far – less than a quarter of the monthly total – but keep in mind we are entering what is traditionally the driest period of the year in Southeast New Brunswick.

A strong ridge of high pressure over Western Canada has pushed the thermometer into record high territory for British Columbia and Alberta.

The major cities were warm too with Calgary reaching 33 C and Edmonton 30 C.

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.

Heat comes to abrupt end

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. 

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.
