The latest storm arrived in far western and southern parts of the state early this morning. This storm will be slow to spread north and east through the afternoon. The rain/snow line is a big focus for this storm. Coastal York and Cumberland county have seen rain through the morning thanks to a strong east wind. It won't be until late today into tonight that Portland sees a change over to snow. The heaviest precipitation from the storm is expected late today into tonight. Snow tapers early tomorrow morning, but we are left with snow/rain showers right through Saturday.
This Afternoon - Rain at the coast. Snow and some sleet mixing in for inland locations. The snow will be heavy at times. Winds will increase through the afternoon and could gusts up to 40mph at times. Plan for a slippery evening commute for Waterville and points west. Bangor will start to get into the leading edge of the precipitation late in the afternoon.
Tonight - Snow will be heavy at times. Most places along the coast should see that transition over to snow. Snow will be wet and heavy so power outages are likely. I have posted predicted snowfall amounts in the "weather extra" section. Notice the tight snowfall gradient close to the coast. That is because of the rain/snow line. I think a couple miles inland will make a huge difference in how much snow we see.
Thursday - This storm tapers during the early morning hours to showers, but the threat of snow and rain showers continues through the day. Winds will ease up, and temperatures will once again warm above the freezing mark for most locations. The winter storm warning posted from the NWS is set to expire at 3pm on Thursday.
Extended Forecast - Clouds and rain/snow showers continue through Saturday. Additional light accumulation is possible. By Sunday that low should be heading out of here and we may see a few breaks of sunshine. Quiet weather kicks of next week.
