Regional Impacts
Multiple thunderstorm cells developing during the afternoon over central and southern NB, the main threats are heavy downpours and damaging winds.
Convective Discussion
Today, the focus for organized convection will be along a cold front currently extending east-west across Gulf of St. Lawrence and northern NB. Isolated pulse-type thunderstorms will develop ahead of the front during the afternoon and into the evening. Some of these storms could become better organized and turn into a multicell arrangement especially over central and southwestern regions. The dynamics over the area are minimal, but moisture below 700mb is plentiful and mixed-layer CAPE approaching 1000 J/kg should be enough to produce fairly robust storms. The Caribou upper air sounding from this morning is showing a layer of dry air above 700mb which would suggest a threat of high wind gusts.
By the end of daylight hours the front will reach northern NS and will begin to weaken as it continues to slump southward during the night.
