Moderate to High Risk Saturday and Sunday #MBSTORM #SKSTORM

Saturday and Sunday looks like it will be a moderate to high risk for severe weather in south east Saskatchewan and southern Manitoba. Baseball size hail with long lived supercells, significant tornadoes, dangerous lightning and damaging winds. Begin your tornado precautions NOW if in these areas, Yorkton south through Regina into Montana, east to the Red River Valley and all of south west Manitoba. Make your plans now and stay safe, monitor weather alerts closely and with full attention, charge weather radios, cell phones, and stock candles and food.
A detailed map will be outlined later tonight as models come in line with the forecast.
Here is the Saturday 6pm NAM Supercell Composite:

Sunday's GFS shows the Supercell Composite Index with soundings at 69.1 (translating to a PDS Tornado, "Particularly Dangerous Situation) just south of the Saskatchewan/Manitoba/North Dakota border intersection:

#abstorm More Small Hail In Large Amounts Today - #mbstorm Landspout Tornadoes

Copious amounts of moisture across the southern prairies today combined with high temperatures will combine to mix in a little of everything, or lot of little things. Yesterday reports out of Okatoks, Alberta showed huge amounts of small hail covering the highways as snow plows had to be called in for what is quite a normal major hail event for the foothills as summer storm season hits its prime time of late June (pictures and tweets below). More of the same is forecast for today with an added bonus of a possibility of landspout tornadoes in southern Manitoba, especially in the Red River Valley. Strong pulse storms will begin early in the day with some becoming near supercellular size in areas south and east of Red Deer Alberta. Southern Saskatchewan could also see some storms reach severe levels with hail and heavy rain as the main factors. Here is a forecast map as drawn up at 7am: This map may be updated as needed later this afternoon. Photos and tweets from yesterday's amazing hail storms in the southern Alberta foothills:

"Several areas to watch this afternoon.." [1pm Updated Risk Map]

Several areas to watch this afternoon for the development of severe thunderstorms. Heavy rain, flash flooding, large hail and intense lightning are the main concerns today and into the overnight. In the north, slow moving storm cells may trigger flash flooding and large hail throughout the afternoon and into the evening. Further south, mainly in south western Manitoba, a strong cold front will trigger supercells late this afternoon and move east overnight. Extreme amounts of precipitation with large hail and possible microbursts could cause localized damaging wind gusts. Very intense lightning will also be of a concern, especially near game time in Winnipeg as the CFL season kicks off there tonight. Here is the latest detailed risk map for today:
