Convective Outlook Valid for Today and Tomorrow

Regional Impacts

 

NS/NB/PEI/NFLD: None

Labrador:  A risk for most regions and a chance of gusty winds and hail southeast.

 

Convective Discussion

 

A low pressure system will track across Labrador today. Ahead of the low, daytime heating will allow temperatures to reach 27 degrees. Modifying the upstream sounding at Sept-Iles yields precipital water of 25- 30 mm, cape of 1000 J/kg and unidirectional shear of 30 kts. Additionally the freezing level is fairly low at 9,000 feet.  An upper level jet will approach this afternoon and southeastern Labrador will be in a favourable area of enhanced lift (left exit). The low freezing levels and decent cape above -10 C will support hail growth. The dry mid levels will support possible wind gusts.
