Recreational Forecast

Mountain Forecast:
Today starts with any sun giving way to increasing and lowering clouds, then scattered showers developing through the Adirondacks, spreading east to the Green Mountains, perhaps a shower late in the White Mountains. South to southwest winds will increase to moderate, while temperatures warm several degrees. On Tuesday, the clouds will be in and out across the southern summits, a few showers, while the clouds obscure the northern summits, with a good chance of showers. Lighter south to southwest winds, and a continued warming trend. The outlook for Wednesday features clouds frequently obscuring the mountains, with a good chance of showers. Temperatures will cool a few degrees, while winds become light, mostly from the southwest.

***During spring, many higher elevation trails are closed. If a trail is muddy, find an alternative trail. Hiking on or around muddy trails increases erosion and damages plant life. ***

Wind At Lower Elevations:
Winds today light, becoming south near 10 mph, increasing to 10 to 15 mph, gusting to 25 mph west of the Green Mountains. For Monday night, south winds 10 mph or less, except 10 to 15 mph in the Champlain Valleys, gusting to 25 mph. On Tuesday, south winds continuing 10 to 15 mph, with gusts to 20 to 30 mph, strongest in the Champlain Valley. The outlook for Wednesday calls for light winds, becoming northwest less than 10 mph.

Detailed Discussion

Through the weekend, various periods of clouds, and some localized showers made it a challenge to see the tremendous displays of Northern Lights – aurora borealis – but where they were seen, they were breath-taking. Our periodic, changeable conditions were the result of a rotation in the upper atmosphere, one of several dotting Canada and the US, each featuring a pocket of colder air above, while inviting a rising motion in the atmosphere, resulting in several somewhat localized, stormy clusters of clouds and showers. For us, Saturday featured limited activity, then more clouds and showers yesterday, Mother’s Day, most frequent through areas from the Green Mountains west, with a specific swirl over NY, some fragments wandering off to the east and north in the afternoon and evening. This morning shows that deteriorating system well off the East Coast, while a minor wedge of high pressure that followed last night, giving us a clearing trend, already slipping off the East Coast as well. That means the periods of morning sun will give way to more clouds this afternoon, along with a rising chance for a few localized, passing showers this afternoon, nothing widespread or long-lasting, spreading from NY into western VT, more localized from the Green Mountains east. Those showers belong to complex of storms and fronts to our west, which spells a better chance of showers, possibly a thunderstorm, from tonight, off and on through Wednesday night. A cold front runs from a storm near James Bay to our northwest, to a second storm along the front in the Great Lakes, continuing southwest to the eastern Plains. A warm front branches southeast from the Great Lakes system, heading our way tonight and tomorrow. Ahead of the warm front, expect milder air and a greater chance of showers tonight into Tuesday, then the warm front lifts them mainly into northern areas during the day tomorrow. Meanwhile, the cold front edges slowly toward us, sparking additional, localized showers or a thunderstorm tomorrow afternoon. With the warm front for northern areas, more scattered to south as the cold front takes its time arriving. Perhaps the best chance of showers comes Tuesday night into Wednesday, with these same weather systems taking their time progressing east. As long as they continue to move along, the end of the week, Thursday and Friday, look drier, though I can’t rule out the potential for a localized shower each day, in part owing to the lack of any significant high pressure coming in to clear things out. Though chaotic, some episodes of rain and intervals of sun, along with seasonably mild temperatures will bring out more leaves, flowers, and the greening of the landscape climbing up from the valleys into the mountains.
