Looks like another setup for possible severe thunderstorms to develop across Southern MB late Thursday into Thursday evening. A low pressure system and trough will be moving across southern SK Thursday moving to the SK/MB border by Thursday evening. A warm front extending east of this system will lie across the MB/ND border by evening which will be the focus for thunderstorm development. South of the warm front, warm and humid air will be advecting north from the Dakotas and will nose into Southern MB especially south and west of Winnipeg. Favourable low level wind shear and an increasing jet stream aloft will set the stage for supercell storms to develop across the Dakotas and southwest MB, with the potential for large hail and possible tornadoes. The limiting factor in this setup will be how much moisture can de drawn into this system in a short period of time, since dewpoints are quite low across the northern Plains today. As a result, the severe weather threat may be late Thursday before sufficient moisture can be drawn into this system. Stay tuned..
