Higher Summits Forecast
Mountain weather is subject to rapid changes and extreme conditions. This forecast is just one tool to help you plan a safe trip (if in doubt, turn around!). Always travel with adequate clothing, shelter, food, and water, and be prepared to make your own assessment of travel and weather conditions. You should never visit the higher summits unprepared.
Summit Forecast Summary
A slow-moving low pressure system will bring increasing rain chances to New England this forecast period. Moist advection will have overcast skies moving across the area by this morning. This system may also introduce widely scattered rain showers or drizzle today, mainly during the afternoon when diurnal instability is greatest. The added diurnal instability may also produce a thunderstorm or two this afternoon. A weak ridge will nudge its way toward New England by Thursday evening. This may allow the higher summits opportunities for clearing Thursday night, but intermittent fog will likely stick around, with neighboring valleys seeing partly sunny skies by Friday. Despite the fog, the higher summits will see winds decrease and possibly become light and variable at times overnight Thursday and into Friday. A warmer day is expected on Friday, with daytime highs forecast to reach the lower 50s at the higher summits. The ridge will eventually exit to the east on Friday, with the slow-moving low pressure arriving in New England by nightfall. Scattered rain showers and thunderstorms are anticipated with this system for Friday afternoon and overnight. The chance for showers and thunderstorms will continue into Saturday, with this weekend looking more wet than dry for most of the region.
