General:

Areas of low clouds and fog breaking for intervals of morning sun, then scattered to numerous showers or a thunderstorm, mostly in the afternoon. Highs in the 60s to low 70s. Light winds becoming west up to 10 mph in the afternoon.

Brief:

A welcomed, showery day yesterday for areas from the Green Mountains west, and through most southern counties into MA, but disappointingly unproductive for northeastern areas, mainly because clouds had released most of their moisture before reaching there. After last evening’s showers and storms settled down, lighter winds and some partial clearing helped patches of low clouds and fog to develop, and are lingering this morning. Today’s situation is similar to yesterday, with a poorly organized storm extending from New Jersey north into Quebec, and a more defined storm in the upper atmosphere to our north. Yet there are some differences. First, some periods of sun today will add a bit of energy and lifting of the atmosphere, favorable for clouds and shower development, including some thunderstorms. Second, a weak cold front is approaching from the west, offering additional energy to create showers and thunderstorms. The result with be scattered to numerous showers and thunderstorms midday and afternoon, a few with some gusty winds and small hail. As the front swings through overnight, the showers and storms will taper off, giving way to clearing from west to east. This leads to a cool but much drier day Wednesday, with readings in the 60s to low 70s, and a fresh northwest breeze. Some fair weather cumulus will show up near the mountains, and a stray mountain sprinkle is possible north late in the day. The rest of the week looks quiet, as large high pressure builds in over the eastern US. By Friday, as it works east into the Atlantic, a warmer southwest wind brings us a warming trend, though nothing more than some 70s to low 80s, close to seasonal averages for mid-June. As this high moves east, it makes room for the next weather front pushing in Friday night and Saturday, with our next chance for showers.

Winds:

At lower elevations, light southwest winds becoming west near 10 mph, with waves on the open waters of Lake Champlain near 1 foot. Tonight, winds becoming northwest near 10 mph, with waves on the open waters of Lake Champlain building to 1 to 2 feet. On Wednesday, winds from the northwest 10 to 15 mph, with waves on the open waters of Lake Champlain 1 to 3 feet. The outlook for Thursday calls for light winds, becoming west near 10 mph, with waves on the open waters of Lake Champlain 1 foot or less.

***winds and waves may be higher in the vicinity of thunderstorms***

Mountain:

The summits today should remain mostly cloudy, maybe a break of morning sun, then clouds in and out across the summits with numerous showers or a thunderstorm likely. Light southwest winds becoming northwest, and little change in temperatures. Wednesday’s forecast calls for sunshine, mixing with afternoon clouds through the Adirondacks into the northern Green and White Mountains. Winds moderate from the northwest, while temperatures cool several degrees. The outlook for Thursday brings lots of sunshine, light to moderate west winds, and temperatures perhaps edging up a degree or two.
