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.

A low pressure system moved into the Maritimes today bringing up to 40 mm of rain to Greater Moncton.
A strong thunderstorm also rolled through Southeast New Brunswick in the early evening with wind speeds clocked as high as 102 km/h.
The brief but powerful gusts downed trees and branches onto power lines and caused thousands of power outages.
Environment Canada had not issued any weather warnings for the region.
The storm replaced a warm air mass which set record highs in at least four New Brunswick communities yesterday.
The hotspot was Kouchibouguac National Park which climbed to 32 C and that beats the maximum from 1992.
Moncton and Doaktown both tied their record highs of 30.6 C for the date.
Winter just doesn’t seem to want to go away!
Environment Canada says numerous communities across New Brunswick set new record lows this morning with Edmundston bottoming out at -28.2 C.
Doaktown and Woodstock both dropped to -22 C.
Greater Moncton had a low of -13.5 C which broke the previous record low of -11.7 C from 1964.

By the time Irene arrived in New Brunswick early this morning, the former hurricane had been downgraded to a post-tropical storm.
The eye of the storm had gotten as close as 70 km northwest of Edmundston as it made its way north from New England to the Gaspe Peninsula and onward to Labrador.
At the storm’s peak, more than 50,000 New Brunswick households had lost power as winds gusting as high as 93 km/h (recorded at Greater Moncton Airport) uprooted trees which brought down power lines around the province.
Most of the rain associated with Irene fell yesterday, with about 20-30 mm in Southeast New Brunswick, and the highest totals at Doaktown and Fredericton with 89 mm reported.
Quebec’s Eastern Townships (left side of storm track which gets mostly rain; right side mostly wind) received the most rain with almost 110 mm at Sherbrooke.
