First off looks like we dodged the more dense fog. Most of the advisroies are to our south and east. The cause I bet is the approaching cold front. I think the first portion of the cold front will push through around 9 / 10AM and then work in phases throughout the day. Here is the temp outlook.
Tuesday Wednesday Thursday Friday Saturday
H 46 H31 H26 H28 H34
L 19 L19 L14 L18 L17
As winds begin to switch Thursday this will bring moisture into the area which could kick off some snow. I would say up to 1 inch will be possible. I will have more details tonight on that.
