This set up a moist easterly flow overnight, bringing rain to Maine and New Hampshire. So far, over two inches of rain has fallen in a narrow band from Brunswick, to Lewiston, to to rumford. This has caused rivers in that area to rise to near or above flood stage. Elsewhere, less rain has fallen, however, most locations have seen between a quarter inch and an inch of rain so far. Rainfall has been convective, with some bands much heavier than others. Radar continues to show several bands of heavier rainfall streaming in off the Atlantic. A flood watch is in effect for southern New Hampshire. The heaviest band is setting up across southern New Hampshire, where the flood watch is in place. Temperatures were in the upper 40s in nearly all locations, with patchy fog. Winds were out of the northeast, running 10 to 20 mph. Low pressure will remain to the south, with high pressure to the north. This will cause rainfall to continue across New Hampshire, and the southern half of Maine today. The heaviest rain is expected across southern New Hampshire and far southern Maine, where additional rainfall of 1 to 2" is expected today, with more rain tonight and Sunday. Daytime highs will struggle to top 50 today, except in northern Maine, where breaks of sun will allow highs to climb well into the 60s. Most areas, however, will be raw with rain, northeast winds gusting to 30 mph at times, and cool daytime temperatures. Conditions will only improve slightly Sunday, as high pressure tries to ridge south from Canada. The biggest improvement will be central Maine, where some sun and warmer temperatures are expected. Rain will continue across far southern Maine, with changeable conditions between. The moist pattern will continue through next week, as another wave of low pressure will slowly lift across New England Monday and Tuesday. This will bring more rain to most locations, keeping daytime highs in the 50s. The overall pattern will continue to be a wet one, with a chance of rain or showers lasting through late last week. === The weather observed at WHITEFIELD, NH at 08:52 AM EDT was: === The weather reported was light rain.
