Convective Outlook Valid for Today and Tomorrow

Thunderstorm Outlook for Day 1- July 24th, 2021

 

Regional Impacts

 

New Brunswick…Isolated thundershowers are possible this afternoon with locally heavy showers and small hail.

 

Convective Discussion

 

A slow moving low pressure system over Newfoundland will slowly drift eastward today while a ridge of high pressure builds into the western Maritimes. There is little in the way of dynamics today, but with solar insolation along with some coastal convergence and cooler air aloft, there may be enough instability to kick up some isolated showers with the risk of a thundershower this afternoon mainly over eastern New Brunswick today. PWAT of 20-25 mm with freezing levels around 9500ft mean that some brief heavy downpours and very small hail are possible.

 

There will also be some showers and Newfoundland and isolated showers in Nova Scotia today.

 

 

Thunderstorm Outlook for Day 2- July 25th, 2021

 

No thunderstorms are expected during the day tomorrow. A trough will be approaching from the west Sunday night and there is the possibility of overnight convection into the early morning hours on Monday.
