Convective Discussion…
A trough of low pressure stretching from New Brunswick to Newfoundland will slowly track eastward today and Friday. Embedded thunderstorms are occurring near and ahead of the trough and are giving downpours of 10-20 mm/hr. Some pop-up thundershowers are possible this afternoon over New Brunswick. Cape values are 200-300 J/kg with shear of 40-60 kts. The shear will be too much to assist with the thunderstorm development so these should remain non-severe. More pop-up thundershowers are possible Friday afternoon over New Brunswick but again the Cape values are quite low.
