Morning Forecast September 25, 2026

0:00Good morning! From the Fairbanks Museum in St. John'sbury, welcome to this morning's edition of an Eye on the Sky. Mainly clear skies and light winds have delivered yet another chilly start to the day, not quite as chilly as yesterday, with scattered frost limited to the cold spots, as well as dense fog and the deeper river valleys. High pressure, though slightly weaker, remains over southern Quebec, nosing south through the central Appalachians, expected to drift northeast during the day today. We'll still see plenty of sunshine for western and northern areas, while the sun begins to fade through some increasing high clouds spreading north from Massachusetts into southern and eastern Vermont and most of New Hampshire. They are the four runners of a significant change this weekend, though well advertised, as the developing storm over the western Atlantic becomes an early season nor Easter, complete with some tropical characteristics. This morning finds that storm 500 miles or so east of the Virginia caves and several 100 miles south of Cape Cod. As it tracks north through tomorrow morning, the clouds will continue to increase, thinnest

1:03northwest and thicker through Massachusetts, southeast Vermont and New Hampshire, with a chance of showers from the storm reaching southernmost locations late to tonight or early tomorrow morning. This storm has been developing apart from the primary airflow and the weather pattern established by the jet stream. In weather terms, it is called a cut-off low, because it is literally cut off from the general airflow. As a result, it will behave more independently in terms of its location and track, requiring forecast to be revised as the details of the storm change over time. Now that the storm has formed and strengthened over the past 24 hours, a more confident forecast is emerging for the weekend. First, the storm will continue to intensify as it spins north, remaining south of Cape Cod by tomorrow morning. Long winds and lashing rains will be buffeting the New England and Long Island shores, decreasing in intensity, but spreading north into our region first as the high clouds today, then thickening clouds tonight and finally periods of rain and showers in Massachusetts, reaching our

2:06southernmost counties late to night or early tomorrow. For those in the St. Lawrence Valley and in northern parts of the Adirondacks, the clouds should stay thin, even a few glimpses of sun, also running a few to several degrees warmer. Meanwhile, the storm stalls and then potentially curls more to the west near or south of Long Island tomorrow night and into Sunday. As the clouds sweep west around the storm, rain and gusty winds are likely from Saturday night through Sunday night, south of the White Mountains root for an Adirondacks with a good chance of showers north to the Adirondacks and root to decreasing to spotty showers north toward the Quebec border. Sunday night into Monday, the storm weakens and slides northeast, causing the showers and clouds to slowly diminish from west to east lingering in New Hampshire right into Tuesday. Now to the forecast details, areas of dense valley fog to start, mostly sunny, mixing with some high clouds north of Route 2 and west of the Green Mountains, sun fading behind increasing clouds through New Hampshire, eastern and southern Vermont, highs mid-60s to low 70s, warmest

3:10north, a light northeast wind. Tonight, periods of clouds north of Route 2 and west of the Green Mountains, cloudy east and south, a chance of showers late near the Massachusetts border, lows in the 40s. Saturday, some limited sun but lots of clouds from the Adirondacks and Route 2 north, mostly cloudy elsewhere, arising chance of showers south of the White Mountains and Route 4 becoming likely in the afternoon, possibly reaching Route 2 late. Hives ranging from 60 south to 70 north, winds increasing out of the northeast, gusting up to 25 miles per hour. Friday night, raining showers likely south of the White Mountains, Route 4 and Adirondacks, a good chance north through Route 2, spotty farther north, lows 40s to near 50 and Sunday. Rain and showers continue often on south of the White Mountains, Route 4 and Adirondacks, still a good chance of some scattered showers north to Route 2, highs upper 50s south to the mid-60s north and west. That's the Weather Story from the Fairbanks Museum in St. John'sbury. Take it a great day, I'm E. B. R. I.R.L.A.R.K.B.E.N. with an eye on the sky.
