New short term model guidance is favoring slightly stronger cold air damming at the surface. This translates to the possibility of a more prolonged period of freezing rain, perhaps lasting through 6am. Model QPF suggests up to a tenth inch of accretion is possible. By 6am, surface temperatures should be above freezing, with plain rain.
(Added at 930pm) As for delay potential, it's another somewhat tricky forecast, because just a half of a degree in surface temperature makes a huge difference. However, I do not think road conditions tomorrow morning will be worse or even comparable for that matter to this past Monday morning.
