Regional Impacts
Interior Newfoundland and Northern New Brunswick.. Low probability of isolated showers or thunderstorms giving 10-15mm.
Southern NS.. 25-25mm possible in embedded thunderstorms.
Convective Discussion
Overall instability is somewhat diminished from yesterday which doesn’t bode well for thunderstorm potential, however many areas likely received 10-15 mm yesterday which is similar to todays potential for some showers. No severe thunderstorms are expected in the general airmass thunderstorms and the main focus of interest is with the broader synoptic area to the southwest of NS. Most of the potential for high rainfall should pass just south of NS but rainfall rates of 25-35mm could just clip southwest parts of the province tonight. However this system seems to have less potential for heavy downpours when compared to some of the recent systems which tended to have significant convection and thunderstorm activity, most of that type of weather will remain further to the south. This system does have high precipitable water values approaching 50mm but the instability is not expected to be significant, these weaker updrafts are less likely to realize the full potential rainfall rates, nevertheless some uncertainty remains and this system could track slightly further north than expected.
