Conditions are favourable for the development of severe thunderstorms with the potential to produce tornadoes. These severe thunderstorms will also have the potential to produce very large hail..Flooding rain..Deadly lightning and powerful winds. Use this time to secure outdoor property and to ensure family members and co-workers are prepared to take action should the severe weather approach. Environment Canada continues to monitor the situation closely for severe thunderstorm development and possible tornado warnings. Please continue to monitor your local media or weatheradio for further updates. Should severe weather approach or if you feel threatened do not wait for warnings to take action..Take shelter immediately. Should you spot a funnel cloud or tornado...And only if it is safe to do so...You can call 1-800-239-0484 to report your sighting. Please note this phone number is for reporting severe weather only.
Details
An approaching low pressure system which gave large hail in portions of Southwestern Saskatchewan today will tap into a very hot and humid airmass as it tracks northeastward tonight. Upper level winds combined with very unstable air will give the potential for tornadoes within portions of the tornado watch area. Severe thunderstorms are also possible further east, up to the Manitoba border. The tornado threat for Prince Albert, Melfort, and Nipawin has diminished with the main threat now being further south.

Tornado Watch Alerts: Saskatchewan http://www.theweathernetwork.com/index.php?product=alerts&pagecontent=prov&provcode=sk
Summary
Conditions are favourable for the development of funnel clouds and tornadoes. These types of tornadoes form out of weak thunderstorms and are usually not as destructive as their severe thunderstorm cousin. They are difficult to track with Doppler radar and can appear without warning. They normally move slowly and can last for many minutes. They often appear as a giant column of dust from the ground to the bottom of the thunderstorm. Their destructive power is usually felt over a very small area. Treat all funnel clouds and tornadoes seriously and avoid when possible. Should one develop nearby take shelter underground or in a reinforced structure like a bathroom or interior closet. If you are in your vehicle try to move away from the tornado at right angles. Environment Canada continues to monitor the situation closely. Please continue to monitor your local media or weatheradio for further updates. Should you spot a funnel cloud or tornado...And only if it is safe to do so...You can call 1-800-239-0484 to report your sighting. Please note this phone number is for reporting severe weather only.
