Thunderstorm Outlook for Day 1

 

 

Regional Impacts (Day 2)

 

New Brunswick:  Isolated to scattered thundershowers tomorrow afternoon and evening.  Potential severe thundershowers giving downpours, gusty winds and hail.

NS/PEI/Labrador: A risk of thundershowers tomorrow afternoon and evening.

NFLD: Nil.

 

Convective Discussion (Day 2)

 

A cold front will cross northern New Brunswick tomorrow afternoon and evening. ML cape values near 1000 J/kg are expected and wind shear near 30 kts.  Freezing levels are high but decent cape exists in the hail growth zone. Dry mid layers will allow for gusty conditions. PWAT values will be near 40 mm so rainfall is a concern. The upper dynamics are supportive as well.
