Thunderstorm Outlook for Day 1 – JULY 9th
Regional Impacts
Non-severe thunderstorms are forecast for Nova Scotia, PEI, Cape Breton, and parts of New Brunswick as Elsa approaches the Maritimes and passes over this evening.
Convective Discussion
With today’s storms, heavy rainfall and lightning will be the main threats. Convection is possible on Elsa’s eastern side as a warm tropical airmass gets pumped into the region and the circulation brings decent midlevel shear. Freezing levels are very high so hail is not expected. Any discrete cells over the marine district could be marginally severe this afternoon and evening with gusts above 70km/h.
Thunderstorm Outlook for Day 2 – JULY 10th
Regional Impacts
Non-severe thunderstorms are possible for areas of southwestern Nova Scotia and SE New Brunswick, in clearing behind Elsa.
Convective Discussion
Storms will be short lived and very isolated. Highly dependent on back-side clearing of synoptic driven clouds.
