Convective Outlook Valid for Today and Tomorrow

Regional Impacts

 

NS/NB/PEI: None

NFLD: A chance of severe wind gusts and downpours this afternoon.

Labrador: Elevated convection giving downpours.

 

Convective Discussion

 

Elevated convection giving downpours is possible in Labrador. Precipital water is 30 mm there and it is in the region of the left exit of a 100 kt jet which is giving it support. Over eastern regions of Newfoundland surface based convection will initiate this afternoon. Precipital water is 40 mm and dry mid layers will allow possible wind gusts to 80 km/hr. A high freezing level of 13,000 feet will limit possible hail size. The sheer is a relatively low 20 kts or less so storms will be mostly pulse in variety.
