Convective Outlook Valid for Today and Tomorrow

Thunderstorm Outlook for Day 1

 

Regional Impacts

Nothing significant for Newfoundland and Labrador and New Brunswick. A chance for isolated showers with near severe rainfall amounts and gusty winds.

 

Convective Discussion

We continue with a deep ridge south, a deep trough extending from Labrador southwest to the Great Lakes, slanting down to a weak low near PEI with cold front extending southwest. NS is in the warm sector, with a weak thermal ridge moving east and weak cold advection approaching. Moisture is good again with PWATs near 40 mm and dewpoints inland in the low twenties, deep layer shear is near 45 kts. If  some clearing occurs, there’s enough instability to give some healthy thundershowers and gusty winds. Freezing levels are near 14k feet, so significant hail is unlikely.

 

 

 

Thunderstorm Outlook for Day 2

Nothing expected over land.
