High pressure will crest and move east today as an area of developing low pressure moves northward from the mid-Atlantic. Today, the fog will lift early but skies above will be increasingly cloudy as the low moves north. Clouds will start as cirrus before thickening and lowering for the overnight hours. Overnight, clouds will be above the summits but associated showers with the low should remain south. Tomorrow, things moisten up allowing for fog to start reforming on the summits. A few showers may spread inland as the low moves north into the Gulf of Maine. Showers will be a mix of freezing rain, sleet and snow as temperatures hover around freezing. As fog forms, rime and glaze ice will generate ice, which can get thick this time of year, making for some slick conditions. Wind chills will be 0-10 above rising 15-25 above today falling back to 0-10 above overnight rebounding to 5-15 above tomorrow.
