Ok. I know there was an event back in Atlanta last year where we got .1-.2" of ice (enough to cause issues on roads) and all that was issued was an SWS during the event. I assume the NWS didn't expect there to be icing, but I had always thought there was a threshold level to issue an advisory/warning.
Either way looks pretty insignificant. Back to watching the models for the weekend system...
The thresholds for State College CWA are here
. I'm not sure about that event... but it .1-.2" of ice definately meets the requirements for a FRA or a WWA if there are several precip types involved, especially in the south.
But precip is expanding nicely to our west (although bright banding is making it look more ominous than it really is). Looking at spc mesoanalysis, were probably still below freezing at most levels and could see a little accumulating snow/sleet at the start. Pavement temperature hovering around 31°F.
