Some clearing may develop this afternoon as high pressure sets up across the region. Temperatures will top out in the 40s for most areas this afternoon. Expect some highs only in the 30s in the mountains and some southern New Hampshire towns may peak out around 50°. The high will become anchored over the Maritimes tonight and Sunday. This will create an east or northeasterly flow across the region which will spread Atlantic moisture inland in the form of some cloudiness for Sunday. Gradually the high will extend its influence further south causing the clouds to break up for Monday. The high will maintain its influence over our weather right through Thursday with fair skies and no precipitation expected. Temperatures will average out above normal except along the coast where occasional daytime sea breezes will keep temperatures a little cooler. The dry warm days and cool nights for the next several days will create ideal conditions to slowly melt the dense snowpack that covers much of northern New England. Otherwise, a rapid snowmelt combined with significant rainfall would produce a serious flood threat. === The weather observed at WHITEFIELD, NH at 06:52 AM EST was: === The skies were cloudy.
