Recreational Forecast
Mountain Forecast:
Across the summits today, a few clouds will give way to lots of sunshine, except more clouds and possibly a shower lingering over the White Mountains. Light northerly winds, and temperatures a few degrees cooler. Wednesday offers morning sunshine, giving way to increasing and lowering clouds, as showers and thunderstorms develop in the Adirondacks, heading east mid to late afternoon, accompanied by light to moderate southwest winds, and little change in temperatures. The outlook for Thursday calls for periods of clouds breaking for increasing sunshine. An isolated shower is a slight possibility, mainly northeast. Light winds shifting to the northwest and becoming moderate, while temperatures cool just a few degrees.
Wind At Lower Elevations:
Winds today light, with waves on the open waters of Lake Champlain less than 1 foot. Tonight, winds light and variable, with waves on the open waters of Lake Champlain 1 foot or less. On Wednesday, winds light, main south to southwest 5 to 10 mph from the Green Mountains west, with waves on the open waters of Lake Champlain less than 1 foot. The outlook for Thursday calls for light, variable winds.

Detailed Discussion
Our cooler, refreshing weekend reverted back to summer-mode yesterday, with plenty of humidity, along with plenty of clouds, clouds which kept readings in the 70s and low 80s, pretty much on track for mid-August. The clouds included some patches of showers and a few rumbles of thunderstorm, stirred up by a weakening cold front easing through yesterday afternoon and evening, more or less falling apart as it reached the western Atlantic. Its unconvincing passage has left some humidity in place, as well as mild temperatures, in the 60s to start the day. The weak airflow behind the front wasn’t very effective in terms of clearing, so we find a fair amount of low clouds and patches of fog as well. This morning we do find a modest wedge of high pressure slipping in from the west, which should gradually increase the sunshine, slowest through NH, where a stray shower or two can’t be ruled out. As the high drifts over us tonight, it should cool a few more degrees, and channels of fog will form through the river valleys, and thermometers dipping to the 40s and 50s. The high weakens over us Wednesday, in part a response to the next weather system heading our way from the Great Lakes. Some morning valley fog burns off to sunshine, and temperatures warm to the 70s and low 80s. But as the front gets closer, the sun gives way to increasing clouds, with a rising chance of showers or thunderstorms by late morning in NY, perhaps holding off until late afternoon east of the Green Mountains into NH, and evening then, mainly north of Rt. 4, with only a few widely scattered showers south late in the day into the evening. What showers there are will fall apart Wednesday night, followed by somewhat cooler and less humid air for Thursday, permitting increasing amounts of sunshine. Although a stray shower can’t be ruled out, the chances are low, and would be mainly confined to the higher terrain. High pressure through the Great Lakes builds east Thursday night into Friday, clearing the skies for a seasonably cool, fairly sunny end to the week. It appears this high should lead us into a pleasant start to the weekend before our next weather system arrives either Sunday or Monday, depending on its timing. At this point, it is still several days away, with any details awaiting more information that comes in during this week. The primarily northwest airflow should deflect any significant warmth and humidity from reaching us over the next several days.
Farm & Garden
Rainfall Forecast:
Mainly dry today, a few stray showers in NH covering 20 percent of the area, with amounts of 0.10 inches or less. A rising chance of showers west to east in northern areas Wednesday afternoon, edging south in hit-or-miss fashion Wednesday night, covering 40 percent of the region, leaving localized amounts of 0.10 to 0.20 inches. An isolated shower possible Thursday, mostly from the Green Mountains east, but generally no rain expected Thursday through Saturday.
Drying Conditions:
Good drying conditions today, only an isolated shower in NH, with minimum relative humidities near 45 percent. Drying conditions becoming fair south, then poor in northern areas Wednesday afternoon as showers spread east. Minimum relative humidities from near 45 percent east to 65 percent west. Good drying conditions return Thursday, with minimum relative humidities near 40 percent. Drying improving to good to excellent Friday and Saturday, after any morning dew and fog gives way to sunshine and lowering humidity.
Frost:
No frost for the foreseeable future.
