The dashed black lines are "surface troughs." This type of boundary is an elongated area of low pressure that typically marks changes in wind direction and/or humidity. Temperature changes are usually modest with surface troughs.
Thanks for contacting us.

What do the black dashed lines (look like fronts) on the national weather map mean? I know the reds and blues, but the black lines are not explained.
Thanks
