However, the thicker and lower clouds remained to our south as high pressure over the Maritimes continued to extend southwest into our area. 4 am temperatures were in the 30s and lower 40s. For today, the high over the Maritimes will weaken allowing low pressure centered south of New England to meander northward. Sunshine will disappear as we head through the day as clouds gradually lower and thicken. Light rain and drizzle may work into coastal and adjacent interior sections by late in the day. The onshore wind will limit highs to near 60 along the coast, and to the 60s further inland. Rain will become more widespread tonight, then linger through Wednesday, as the low remains to our south and the onshore flow persists. Clouds and precipitation will limit temperatures the next day or so with readings generally within a few degrees either side of 50. This system will weaken by Thursday, and we may see a brief break in the wet weather before another more significant system arrives by Friday. This second system will inch eastward from the Great Lakes and provide cool unsettled weather into the upcoming weekend. There are signs that high pressure over the Maritimes will try to build southwest into the area for the second half of the weekend. If this occurs, it will push the Great Lakes system a bit further west and dry out Maine and much of New Hampshire for much of Sunday and early next week. === The weather observed at WHITEFIELD, NH at 08:52 AM EDT was: === The skies were clear.
