An absolute mess is occurring across the region with surface observations showing below freezing temps across much of the interior. With moderate to heavy rain falling, ice accretion remains a fairly significant concern. Freezing rain will slowly transition to rain this evening as warm air noses in from the east. This transition will be slow to occur especially over inland areas. Storm total ice is likely to be in the .25-.5″ range which is in line with my forecast from last night.
Rain will continue to increase in intensity this evening and the heaviest precip will arrive in the form of a line of showers and thunderstorms late tonight into early tomorrow morning. By this time, cold air should be pushed well to the north and no icing concerns are expected. The concern with this will be winds and heavy rain which could lead to power outages and some nuisance flooding respectively. Winds could gust to 45mph in the stronger storms.
Winds and rain move out Thursday afternoon with some breaks of sun possible. Clouds move back in Thursday evening and a little more snow is possible for the mountains as upsloping kicks in. Accumulations should remain under 3″ and will be confined to the higher elevations.
