These are very good questions Anthony. Yes the first system will likely have an effect on the second one, and the second one will have an effect on the third, due to arrive early Friday afternoon.

At this time, I am most concerned about the first one and the one early Friday afternoon if it develops. The first one looks to develop along a prefrontal trough and comes through with the best instability (heating and moisture). The earlier this line reaches us, the more severe it is likely to be since it will benefit from more heating. I'm less concerned about the second batch of showers, due to arrive early Friday morning. This disturbance will not have the benefit of much heating and will likely be robbed of some of the moisture from the previous squall line. Lastly, if we are able to get some sunshine in here Friday morning or very early afternoon, then along the cold front itself I would expect a narrow but possibly intense line of storms to develop. This one would be capable of some large hail and damaging winds. That is if, we get some heating.

Moral of the story, we need to be on our toes late Thursday and into early Friday afternoon.

Stay tuned and keep studying the weather!
