This set up a easterly flow across northern New England, resulting in a rather dreary and showery night. At 300 am radar showed showers across most of Maine, and eastern New Hampshire. The showers were not particularly heavy, with generally less than a quarter inch overnight. Temperatures were in the upper 40s to around 50 across the entire region. The warmest temperatures were in the mountains, inland furthern from the cool ocean waters. The upper level pattern responsible for for the rainy weather the past couple days will remain in place well into next week. Low pressure will remain near the Great Lakes, with high pressure anchoring in northern Quebec. This will set up a persistent easterly flow, which will bring rain to most areas today and tonight. Across southern New Hampshire, this rain will be heavy at times, with storm totals well in excess of two inches possible. A flood watch is in effect for some counties in southern New Hampshire. Temperatures will remain cool through the day, with highs in the lower 50s. On Saturday, high pressure will slowly build in from the north, ending rain in northern and eventually central Maine. Rain will linger across southern New Hampshire through Saturday and possibly into Saturday night. Daytime highs this weekend will be in the 50s in southern sections, but in the mountains where there will be some sunshine, daytime highs will be in the 60s. Another wave develops in association with the upper level low, lifting closer to the region Monday, than across the region Tuesday and Wednesday. This will bring a chance of rain to all areas during this period, with continued cool temperatures. === The weather observed at WHITEFIELD, NH at 08:52 AM EDT was: === The skies were mostly cloudy.
