 SYNOPSIS: A vertically stacked area of low pressure over the tip of Labrador heads for southern Greenland. Upper-level ridging to the west brings a surface high in from the Great Lakes. An upper-level trough over Western Canada brings a clipper system into the region for Friday. WEDNESDAY: A mainly sunny day is expected south and east of the mountains. The northwest breeze from the Labrador storm continues for the hills, north, and east, where it may gust around 15-20 mph. High temperatures range from around freezing along the Quebec border to the mid-40s along the coast. Wind chill values will knock 5-10° off actual temperatures, making it feel like the 20s & 30s. WEDNESDAY NIGHT: High pressure settles in, the breeze drops, and the sky clears over the mountains. Areas with snow on the ground can expect a chilly night as radiational cooling sets up. Single-digit low temperatures are possible in the valleys of the western mountains along the border, to the teens over much of the interior, to the low to mid 20s along the coast. THURSDAY: With the surface high overhead, it will be a mostly sunny day statewide, with little wind and thus slightly warmer temperatures, with mid-30s in the north and mountains, and mid-40s along the shorelines. THURSDAY NIGHT: A few high clouds may stream in from the west, but it appears mainly clear. Low temperatures range in the teens for the mountain valleys to around 30° at the shorelines. FRIDAY: A clipper is expected to pass through the region. Early-week ideas showed a bit of substance with the system, but it has turned into a Bronx cheer. Precipitation arrives along the Quebec border mid-morning to noon. Some elevation snow is possible with rain showers in the valleys and north. Areas to the south may get a sprinkle, and the eastern regions may not get much more than that. High temperatures range from the upper 30s in the interior to the upper 40s on the coast. THE WEEKEND: Saturday looks breezy and chilly, with snow showers possible in the mountains as the northwest wind picks up. Sunday looks fair with less wind.  EXTENDED OUTLOOK: The graphic here covers the bases. This pattern is very similar to what the region experienced last winter. The ongoing drought situation will fluctuate from week to week, with some improvement and some worsening depending on the activity and region. Fingers crossed for another backloaded winter, but that is not a lock at this point. The only concern I have through early December is the potential for wind at times. This annoying pattern of being in the area of early storm development, which blows up to the east/northeast and gives Atlantic Canada most of the precipitation, while Maine is left with the backside wind and charity snow showers along the Quebec border region. A great weekend ahead for an oceanside escape! |
