General Forecast:
Mostly sunny and seasonably cool. Highs in the upper 60s to low 70s. Winds light, becoming north near 10 mph.
Brief Discussion:
We start with a rather chilly morning for this time of year, in the low to mid 40s, even some mid 30s in the colder mountain valleys north. It dipped to a frosty 32 at Saranac Lake in the Adirondacks. Light winds and moist ground has also promoted some river valley fog, quite dense in a few spots. But our early sunrises, clear skies, and strong sunshine will take care of the dampness and chill, burning off the fog, and sending temperatures into the upper 60s and low 70s. While that is cool for June, it's warmer than many days recently. Most noticeable – no rain! In fact, for most locations, we should remain dry into the better part of the upcoming weekend.
High pressure, which originated across the tundra of northern Canada – accounting for the chill, is centered this morning just to the north and west of Ottawa, stretching from central Quebec southwest through the Great Lakes. This is our weather maker, keeping the skies mainly clear, and the winds light. Because this high has moved south from the tundra, the sun is gradually warming this airmass, so we can look for a warming trend heading into the weekend.
With the high pressure system cresting over us tonight, we’ll have one more cool, crisp night, including some 30s once again, in the colder mountain valleys north. The high edges to the east tomorrow, taking the coolest air with it. In addition, a light southerly wind will start to moderate the cool weather, climbing into the 70s. A weak cold front will drift south into southern Quebec Thursday night into Friday, mainly promoting some clouds, though an isolated afternoon shower is possible north Friday afternoon. This boundary will weaken, but what is left will drift over us this weekend. It won’t be enough to affect temperatures, but it could be just enough to help a isolated shower or thunderstorm develop in the afternoons. Regardless, the temperatures and increasing levels of humidity will set the stage for much more typical summer weather next week.
Mountain Forecast:
The summits will enjoy sunshine and relatively light winds through Thursday, excellent visibilities, and a gradual warming trend.

Sunrise on this 19th of June was at 5:06, and will set this evening at 8:37, 15 hours and 31 minutes later.
Some of the hottest weather of the 20th century was scorching our normally temperate region on this date in 1995. The mercury soared to 100 degrees in Burlington, VT, as well as in North Conway, NH, and did the same in Vernon, VT the following day. These figures not only set records for the dates, but gave Burlington its hottest June temperature on record, and only the second time the thermometer had ever reached 100 or more.

Rainfall Amounts: No rain expected today through Friday, although an isolated shower can't be ruled out Friday afternoon. Saturday and Sunday will be mainly dry, though a few isolated showers or thunderstorms are possible.
Drying Conditions: Drying conditions today and Thursday will be good to excellent, with minimum relative humidities near 30 percent. Good to excellent drying continuing Friday and Saturday, though an isolated shower is possible. Good drying on Sunday, with an isolated shower or thunderstorm possible, and increasingly levels of humidity inhibiting some of the drying.
Frost: We are now past the average last date of frost in the cold spots of the region. No frost forecasts will be issued on a regular basis until September 1st, unless conditions warrant.
