Severe thunderstorms affecting SW Manitoba this morning.. showers/tstorms spreading into RRV this afternoon into tonight

Severe thunderstorms have developed over SW Manitoba this morning in advance of a warm front pushing north from North Dakota. This front is pushing in very unstable air aloft which has triggered strong to severe thunderstorms with large hail and very heavy rain across SW Manitoba. Quarter to golf ball size hail has been reported in some localities with 25 to 45 mm of torrential rain falling within 1 or 2 hours, in areas that are still recovering from 50 to 75 mm of rain from earlier this week. The severe thunderstorms will continue this morning with additional showers and thunderstorms spreading into the Red River valley this afternoon into tonight. Some storms may continue to be severe with locally large hail and very heavy rainfall. Stay tuned..

  2. Some good storms on radar...might see a little sunlight by 3 or 4 this afternoon, but I think that after we're done with these storms, we'll be done for the most part.

    Impressive hail pictures out of SW MB being posted onto the the Weather Network photo gallery.. some almost as big as baseballs!

  4. Torrential rainfall rates with these cells to the north.. personal weather station in Selkirk recorded 37 mm of rain in 20 minutes between 2:40 and 3 pm. That will cause some drainage problems..

  6. Check out EC's forecasts for northern Alberta and Saskatchewan! Unbelievable! It's June 3 tomorrow and they (Slave Lake, Fort McM, Peace River, Collins Bay) are all expecting highs near the freezing point, with snow. Snow forecast for Edson and Jasper as well. This makes it the 3rd lousy June in a row.

  11. Yeah, those Lake Manitoba pictures are devastating.. in some areas, it really does look like a tsunami hit them. On top of that they got hit with heavy rain and hail today. They can't catch a break this year.. just relentless.
