We are currently watching an area in Northern Ontario for the development of severe thunderstorms.


Thunderstorm Forecast, for Northern Ontario. Issued July 4th, 2019.

Areas extending between the United States border near Quetico Park and Cloud Bay through to portions of Far Northern Ontario near James Bay expect some isolated to scattered severe thunderstorms today. This includes Armstrong, Nipigon, Thunder Bay, Nakina, Ogoki, and Fort Albany. This is highlighted in green and marked with a '1'.


Thunderstorms are expected to develop from Quetico Park through to Gull Bay and Armstrong. These thunderstorms will move east where further intensification and development is likely to occur. This is highlighted in the 'area of interest'. This is where severe thunderstorms are most likely to form. This includes Thunder Bay, Nipigon, Nakina, and Beardmore. The thunderstorms will mainly be isolated but could quickly become scattered with multiple clusters of thunderstorms.


Into the evening, the storms are likely to 'stall' before weakening, this could lead to some localized flooding. Severe thunderstorms may continue east and/or have a low development chance towards the Geraldton, and Longlac regions as well as between Fort Albany and Moosonee.


The main threats in the severe thunderstorms are large hail between 1-3cm, damaging winds between 70 and 90km/h and heavy rain over 50mm. There is a non-zero tornado risk in the 'area of interest' as well.


Otherwise, non-severe thunderstorms are possible in the blue region which is marked with a '1'.
