Weekend warm up will come with fog

Look at these overnight temperatures!  Thankfully, Thursday night isn't looking nearly as cold.  Southwest winds and increasing cloud cover will cause temperatures to rise overnight into Friday morning.

While temperatures will warm into the weekend, we won't feel the full effects of it thanks to snow cover and fog.  Temperatures a few thousand feet above the surface will warm well above freezing, but closer to the surface remain right around 32 degrees.  With the warmer air Friday night into Saturday this will cause what meteorologists call an 'inversion' to develop.  Inversions during the winter time are usually notorious for keeping cloud cover and fog around.  With the added moisture in the atmosphere from some snow melt Thursday and Friday, fog will likely form overnight Friday.  With temperatures still below freezing, freezing fog will be possible by Saturday morning - and likely throughout the day Saturday.  The combination of cloud cover, fog and snow will limit how far temperatures rise on Saturday.  Highs will get close to freezing, but not too much above.  Saturday night will be relatively mild as well, but light freezing rain will be possible Sunday afternoon with another clipper that moves through by Sunday night.
