The sun had been out over southern portions of Maine, but this will not last too much longer. A cold front headed in from the west will push clouds and showers through all areas later this afternoon. Temperatures are expected to climb into the lower and mid 60s in southernmost sections of both states this afternoon. The cooler 50s are going to be more common in the northern half of New Hampshire and the northern two thirds of Maine. Westerly winds will strengthen behind the cold front at first, but then settle down a bit overnight. Low temperatures by morning will head below freezing in most locations. Coldest spots are going to be in the more protected mountain areas where mid and upper teens can be expected. After that chilly start to our day, we will see partly cloudy conditions in most locations on Wednesday, although a few instability showers will be popping up through the mountains. Dry conditions are forecast for the day away from the mountains with plenty of sunshine. Daytime highs should be close to normal well south in both states, and just below normal levels in the central and northern areas. A weak disturbance swings in from the northwest Wednesday afternoon so showers of rain and snow will develop over the mountains and North country. Dry air follows later in the night, with fair skies and dry conditions setting up shop right into to the first part of the weekend. Daytime temperatures are probably going to be pretty steady during the period, warming only slightly at weeks end even as an area of surface high pressure builds in. === The weather observed at WHITEFIELD, NH at 10:52 AM EDT was: === The skies were mostly cloudy.
