July 15th Severe Weather Outlook

715

Stationary front has moved further south across the deep south. Low pressure is off the coast of the carolinas attached to this stationary front.

This is the low pressure that some weather outlets were talking about tropical development but as long as it would be associated and attached to a frontal system it can not be considered tropical.

Anyways that stationary front goes back west to another area of low pressure over Mississippi/Alabama border…to a low pressure over SE Colorado.

Another frontal system with an area of low pressure over SE Montana.

The low over Montana is going to slowly move east pushing a warm front to the north and east.

A cold front from a low pressure system over Canada will catch up with this area of low pressure and warm front.

So by 00z we have a warm front with a area of low pressure over the Dakotas with the warm front stretching towards upper Michigan. The cold front on top of this area of low pressure and then stretching back west to the PNW with multiple pieces of energy.

This will be the focal point for storms in that region.

And it will be the stationary front across the south that continues to provide showers and thunderstorms with the potential for some to be severe.

The main threats of severe will once again be large hail and winds though isolated tornado’s can not be ruled out across parts of the region. Mainly the NE side of the low pressure system .
