From the WABI-TV5 & CW Forecast Center:
A WINTER STORM WARNING is now up for Sunday into Monday. Heavy, wet snow is likely in these areas and will accumulate to between 8-16″. A WINTER WEATHER ADVISORY has been posted due to the likelihood for sleet, freezing rain, and snow in the areas away from the coast. Areas also the coast are under a FLOOD WATCH because of the heavy rain (over 2″ possible) that is expected over the next couple of days. (The colors in Canada are snowfall warnings and off the coast ae marine gale watches.)
High pressure will bring fair and milder weather to Maine today as temps climb into the low 40s up north and into the mid 40s to near 50 over southern parts of the state. Clouds ahead of our next storm will begin to return to our region later this afternoon, but conditions will remain dry until later in the evening. The new storm will slide off the Mid-Atlantic Coastline tonight and then very slowly move northeast just to our south Sunday through Monday. This new storm will bring a mixed bag of precipitation to Maine beginning later tonight and continue thru Sunday and into early Monday morning. The exact track of the storm will determine precipitation types across our region, but at this point it appears northern parts of Maine will see mostly snow, with central areas seeing a mixture of snow, ice and some rain. Southern and coastal Maine will likely see mostly rain, with a little snow and ice mixing in from time to time.
The storm will produce significant amounts of precipitation across our region, with areas that stay mostly snow likely seeing over 6” pile up. The combination of the wet snow and ice along with a gusty wind will likely cause problems with power outages. Flooding will be the main concern over southern and coastal Maine where 1 to 3” of rain combined with melting snow will cause rises on area streams and rivers. The storm will finally pull away from our region later Monday afternoon or night, with approaching high pressure bringing some partial sunshine back to Maine Tuesday.
Today: Partly sunny then increasing clouds, with high temps in the 40s.
Tonight: Thickening clouds, with rain, sleet, freezing rain and snow developing and low temps in the mid 20s to mid 30s from north to south.
Sunday: Blustery, with snow and ice likely north, rain and ice likely south, with high temps in the 30s.
Monday: Lingering mix and blustery, with high temps in the mid 30s to low 40s.
Tuesday: Partly sunny then increasing clouds, with high temps in the 40s.
Wednesday: Variably cloudy, with possible scattered rain and snow showers and high temps in the upper 30s to mid 40s.
