Shower and storm activity is expected across several areas of the country through the weekend with some severe weather and heavy rain expected with some of the stronger storms.
First, a disturbance tracks westward through the Southeast through the weekend bringing scattered showers and storms to the western Carolinas, GA, FL, MS, AL, and MS. An isolated severe storm is possible, but much of this activity should stay below severe criteria.
Next, a monsoonal pattern will be in place across parts of the west with scattered storms expected through the weekend in UT, AZ, CO, and NM. The main hazard with this activity should mainly be heavier downpours.
Finally, a storm system will move through Canada through the weekend with a cold front draped well south into the US. A strong disturbance is expected to accompany this front and move through the Northern Plains tonight, Upper Midwest Saturday, and then into the eastern thirds of the country on Sunday. A highly unstable air mass develops today across the Plains and into MN and northwest WI and will set up a threat for severe storms beginning late this afternoon into the evening and building east into the overnight. Initial development is expected in the central Dakotas and northwest NE this afternoon and will move east and increase in coverage through the night. The best chances for severe storms will come in the eastern Dakotas and northwest MN this evening with the possibility as far south as KS and could advance as far east as northwest WI by Saturday morning. By Sunday the cold front will bring showers and storms to areas from the eastern Great Lakes to the Gulf Coast.
