General:

Mostly sunny, with some high clouds mixing in during the afternoon. Not as cool. Highs ranging through the 60s. Winds north to northwest near 10 mph, gusting to 25 mph east of the Green Mountains.

Brief:

Yesterday’s gusty northwest winds returned the familiar chill we’ve had most of the spring, with temperatures averaging a little below normal from April through the first three weeks of May. Flotillas and clouds and passing showers, mainly in northeastern areas, added to the chill, so it comes as no surprise that the colder mountain valleys of the Adirondacks have dipped to 30 degrees. The good news is that cool, dry high pressure will build over us today, which means lots of sunshine, not quite so blustery, and several degrees warmer than yesterday. It will still be breezy and cool, but a considerable improvement. That high will edge to the East Coast for tomorrow morning, while some moisture attempts to push east. We’ll see a hint of that with some high clouds this afternoon, and increasing clouds overnight. By Thursday, a storm tracking northeast into the Great Lakes will lift a warm front toward us. It means a rising chance of afternoon showers Thursday, especially west of the Green Mountains, while the developing southerly airflow lifts thermometers back to seasonable levels. The warm front will quickly be followed by a cold front as the storm slides from Montreal southeast into Maine Thursday night. Showers will become numerous late Thursday through NY, and thunderstorms, a few of them strong, will develop, reaching western VT, but just showers east of the Greens. The showers taper off Friday morning, though some leftover moisture Friday will leave us with an unsettled day – variable clouds, some sun, and a leftover shower. Yet another storm system approaches Saturday, with a rising chance of showers, becoming likely in the afternoon. If that timing holds, the showers will move out Saturday night, leaving Sunday with generally fair skies and seasonable temperatures. By Memorial Day, Monday, the next weather system races in, with a chance of afternoon showers or a thunderstorm.

Winds:

Winds today from the north to northwest 10 to 15 mph, gusting to 25 mph east of the Green Mountains, with waves on the open waters of Lake Champlain 1 to 2 feet, subsiding to near 1 foot. Winds overnight from the north near 10 mph this evening, diminishing to light east of the Green Mountains, and becoming southeast from the Green Mountains west near 10 mph, with waves on the open waters of Lake Champlain near 1 foot. On Thursday, winds becoming south near 10 mph east of the Green Mountains, and 10 to 15 mph, gusting to 30 mph from the Green Mountains west, with waves on the open waters of Lake Champlain building to 2 to 3 feet. Friday’s outlook calls for northwest winds 10 to 15 mph, gusting to 30 mph.

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

Mountain:

Mostly sunny skies expected across the summits, with any clouds capping the Presidential Range lifting and breaking. Moderate northwest winds decreasing, and temperatures moderating, though still cool for late May. On Thursday, some sun giving way to increasing and lowering clouds, with a rising chance of afternoon showers and potentially strong thunderstorms in the Adirondacks, reaching the Green Mountains and Berkshires later in the afternoon, and mainly showers in the Northeast Kingdom into the White Mountains toward evening. Winds becoming south to southwest and increasing to moderate, as temperatures continue to moderate. Friday’s outlook calls for summits in and out of the clouds to start, with a few passing showers, and some breaks of sun. Winds moderate to strong from the northwest, and temperatures a few degrees cooler.
**The late melting snow and saturated ground mean that hiking trails are NOT all ready for foot traffic. Please avoid muddy trails through the end of the month, as conditions gradually improve.**
