Severe weather threat for Friday

A strong cold front will be bringing the threat for severe storms to the area Friday afternoon and evening. There are a few things that may reduce or enhance the chances of severe storms. Mainly the timing of the front and the amount of heating and instability that is achieved prior to arrival of this front. Right now that arrival and threat appears to be late afternoon and evening with the primary threat being straight line winds. If the front arrives sooner then the threat could be diminished but if it arrives slower during the heating of the late day and evening then the severe threat could increase. Below is a video discussion of the potential event.
