Severe Weather July 21st Potential


CAPE 500-1500 across the region..
Bulk Shear 800-350 level is 35-50 knots
LI -2 to -6 across the region 
Lapse Rates 5.5- 6.5
Air loft in the 500 mb region cooling to -12 to -14 degrees celcius..

With low pressure developing along the stationary front and moving off towards the NE..this is going to serve as a trigger across the area to perhaps cause some thunderstorms to become severe! I am still not expecting a widespread outbreak but more isolated in nature. Main concern will be hail and heavy rain with any thunderstorms.
