The area of showers and thunderstorms over the Great Lakes and New York state Saturday and last night, continued to dissipate as it moved our way. A few sprinkles appeared to be traversing southern New Hampshire at mid morning, although surface observations did not bear this out, as it appeared none of this precipitation was reaching the ground. On top of Mount Washington was the only report of any rain at all. Clouds were breaking across the mountains at mid morning, and the back edge of the mass of clouds overhead was pushing south out of Canada, so sunshine is expected to break out this afternoon across much of the region. A cold front to our north will bear down on the region later today. Ahead of this front an area of cloudiness will spill into the region from the northwest. This may kick off a few showers, and possibly a thunderstorm today. Temperatures should still be very warm today, despite having less sunshine than yesterday. Afternoon highs should top 80 just about everywhere, except the coast where 70s will be more common. The front will drop south of the region tonight. This will allow winds to shift to the northeast bringing in cooler air. High pressure will build south from eastern Canada on Tuesday creating an easterly flow off the cold ocean. This will give us much cooler temperatures on Tuesday despite a fair amount of sunshine. The coldest weather will be felt along the immediate coast, though the oceans influence will spread well inland with the easterly winds. The high will settle out over the ocean on Wednesday allowing winds to turn more southerly. This will reduce the impact of the ocean on our temperatures, especially over New Hampshire. A cold front will bear down on the region late Thursday, bringing a chance of showers to the mountains. Low pressure will form along this boundary, causing it to slow down. As the low and front drag slowly across the region the threat of showers will spread to the coast Thursday night and continue into Saturday, before a ridge of high pressure brings some improvement on Sunday. === The weather observed at WHITEFIELD, NH at 09:52 AM EDT was: === The skies were clear.
