Thursday will be unsettled and slightly warmer with the FL rising to around 1000 m. Friday morning at this time looks to be overcast as a weak impulse of moisture moves through with isolated flurries in the morning, improving to unsettled by the afternoon. Models are not consistent past Thursday so stand by. Saturday is looking unsettled before a frontal band arrives for Sunday with some more snow. Snow conditions at this time are very good. Enjoy the day.
