Unsettled weather is in the forecast for today as a coastal storm intensifies to our southeast, and a strong cold front approaches from the west. Unfortunately, these two features won’t join together until they’re well east of our area, so we’ll have to wait a bit longer for a blockbuster snow event.
That said, an inverted trough has developed between the offshore system and the cold front back to our west. While not intense enough to qualify as a Norlun trough, the dynamics powering this feature are similar and a narrow band of snow showers has already developed along this feature from Casco Bay to Bethel, as seen on radar imagery below.
This light snow will linger for another couple hours this morning with a coating-1″ of accumulation expected. This afternoon, steady snow will be replaced by more isolated snow showers and squalls as the cold front moves in from the west. These showers and squalls will be most intense in the mountains, where an inch or two of accumulation is expected in the higher terrain. Dustings are more likely in the valleys.
Cold air will begin pouring into the region on west-northwesterly winds behind the cold front this evening. Winds will gust up to 30 mph overnight, which will be enough to push wind chill values into uncomfortable territory but shouldn’t cause any major disruptions.
High temps will range from 25 in the mountains to 40 along the NH Seacoast.
