Recreational Forecast
Mountain Forecast:
For the summits, today calls for sun, mixed with afternoon clouds and just an isolated shower in the Adirondacks, with northwest winds decreasing, turning to the southwest, and temperatures climbing a few more degrees. On Tuesday, partly sunny skies, with more afternoon clouds north, and a few localized passing showers or a stray thunderstorm. West to southwest winds increasing to moderate from the southwest, and temperatures continuing to warm. Wednesday’s outlook features variable clouds and sun, along with a few localized, passing afternoon showers or a thunderstorm. Moderate northwest winds decreasing, then turning to the southwest, and temperatures remaining quite warm.
***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. ***

Detailed Discussion
The weekend started unsettled Saturday, with some clouds and a few localized showers, part of a weather front from the west, as well as moisture coming in from the Atlantic, thanks to an ocean storm creating an easterly airflow. This storm kept clouds over eastern VT and NH much of the day yesterday, in the 60s to low 70s, but lots of sunshine west sent readings to the 70s to near 80. Weak high pressure has been building in over the past 24 hours, giving a clear night last night, with upper 40s and 50s, and some river valley fog to start the day today. That fog is already burning off, setting us up for an early summer day, plenty of sunshine, and temperatures climbing to the upper 70s to low 80s this afternoon. That high drifts to the east coast by tomorrow morning, with another mainly clear, mild night, and an even warmer day tomorrow, mostly in the low to mid 80s, though a few warmer valleys will approach 90. With the high slipping a bit more to the south, a weak cold front to our north will attempt to edge closer, sparking a few localized showers or a thunderstorm later tomorrow afternoon into the evening, mainly through Quebec and into our northern counties. They become a little more numerous tomorrow night as a minor disturbance tracks east through Quebec, then move out Wednesday morning, with a very warm, more humid summer day, in the 80s to perhaps a few low 90s, close to record highs for the date. While warm air expands through the eastern US, cold air drops into the west, marked by a storm and energetic cold front. It creates a potent situation for strong to severe thunderstorms in the Great Plains and into the Midwest. By Wednesday night, that system approaches us, with an increasing chance of showers and thunderstorms, continuing into Thursday. How widespread the showers will be, and the potential for thunderstorms depends on several factors, including the timing of the front, and how strong it is by that time. If the front is slower, the atmosphere will have more time to warm up, leading to more numerous showers, and possibly stronger thunderstorms, a situation that will be monitored as it gets closer. Cooler, drier air follows for the end of the week.
