General Forecast:
High pressure centered over the Great Lakes this morning, and low pressure heading for Labrador will help generate a gusty northwest wind, and deliver a mostly sunny day. Some periods of clouds will develop over portions of southern Quebec and the northern mountains this afternoon. Clear skies and diminishing winds will lead to widespread frost and freezing temperatures tonight. Sunny, milder weather expected Friday, with lighter winds, as the high moves over us. A weather front well to our north Friday night into Saturday morning may bring northern sections a few clouds, otherwise sunny and warmer weather continues through the upcoming weekend.

Some periods of clouds will develop over portions of southern Quebec and the northern mountains this afternoon. Clear skies and diminishing winds will lead to widespread frost and freezing temperatures tonight. Sunny, milder weather expected Friday, with lighter winds, as the high moves over us. A weather front well to our north Friday night into Saturday morning may bring northern sections a few clouds, otherwise sunny and warmer weather continues through the upcoming weekend.
Frost: Clear skies and calm winds tonight will lead to frost and freezing temperatures in many locations, especially low-lying valleys. Temperatures near Lake Champlain will be closer to 40 degrees, but even there, sheltered locations could see scattered frost. A warming trend should follow into the weekend.
Rainfall Amounts: Dry weather expected through the weekend.
Drying Conditions: Sunny, dry weather is expected today and Friday, extending into the weekend. Good to excellent drying conditions, with minimum relative humidities near 30 percent.
