Low pressure tracks to the northeast WEDNESDAY: A vertically stacked area of low pressure just west of the Great Lakes at 4 AM tracks to the northeast toward western Quebec. A warm front to the south tries to jam its way into the region, but it will be cut off by a trailing cold front along the Illinois/Indiana border as the system moves to the northeast. Early morning showers taper off from southwest to northeast. Patchy fog is possible as dew points rise, especially over interior areas with a snowpack. Isolated light rain showers and/or patchy drizzle are possible across the region. High temperatures range from the mid-30s north to near 60° in the York/Kittery area. Wind is expected to be light and variable. WEDNESDAY NIGHT: The cold front approaches the region. Rain shower chances increase for interior areas into the evening, with isolated activity to the south and east. Cold air works in on the back side and may bring an inch or two of pasty snow to the higher elevations. The northwest wind picks up as daylight approaches on the backside of the boundary. Low temperatures range from around 30° in the north to around 40° along the shorelines. THANKSGIVING DAY: Any rain/snow over the north to start tapers to snow showers by mid-morning. A west/northwest wind blows cooler air into the region and becomes gusty in the 15-25 mph range (ski slopes 25-35 mph). Upslope snow showers are likely in the mountains. High temperatures range in the 30s along the Quebec border region to the upper 40s along the shorelines, but the wind chill makes it feel like the 20s and 30s. THANKSGIVING NIGHT THROUGH SATURDAY: The chill of the breeze and elevation snow showers persist through the period. Low temperatures to start Friday are expected in the 20s, with high temperatures around 32° in the interior and the low 40s on the coast, with feels-like temperatures in the 20s and 30s. Saturday starts in the teens and 20s, with highs in the 20s and 30s, as the breeze gradually diminishes. EXTENDED OUTLOOK: A warm front approaches from the southwest and may bring snow showers to interior areas Sunday afternoon. Interior snow, with pockets of ice, then changing to rain, is possible Sunday night, with the coastal plain seeing rainfall. Snow showers are likely for the mountains on Monday. The next potential system is possible Tuesday/Wednesday next week. Could this be the coastal areas' first decent snow/junk event, or is that the model hype train again? It all depends on the trough working in on Monday into Tuesday. A stronger trough means charity flakes for the shorelines; a weaker trough means the snowplows may be needed. Stay tuned!
