I worked in meteorological services research a long time ago.

BTW, the storm was predicted (which is why I knew about it). You listened to the wrong meteorologists. :-)

Today's hint: The best forecasts are probably still done by the government/military, and those forecasts are the ones done for airports (only). The ice storm warning I saw was for Hartsfield and was issued Monday for Tuesday.

Private services like Accuweather and the Weather Channel will probably give better current local conditions (other than at the airport, of course). Other than that, my advice would be to go with local airport forecasts/conditions and look at the radar over the past few hours.
