A wide band of rain remained over southern New Hampshire into the early morning hours. Snow and sleet were mixed with the rain over some higher terrain. Rainfall totals for the 6 hour period ending at 1 am showed that .01 to .03" of rain fell in western Maine during the period. New Hampshire totals ranged from .01" in the north to almost a quarter of an inch in the southwest. A nearly stationary front extends from Montana to Nebraska and east to the Atlantic coast south of New England. Any number of low pressure centers are moving east along the front. South of the front temperatures are 50 to 60° or warmer, while north of the front it is still wintry, with temperatures generally in the 30s and colder. A high pressure system centered west of Hudson Bay extends a narrow ridge southeast into New England. The ridge is presently holding precipitation at bay for most of the region, and that should continue today. As the ridge pulls away to the northeast, precipitation will edge back into the region this afternoon, and become more widespread tonight. Nighttime precipitation should be mostly light snow. The chance for snow will continue Friday, mixing with or changing to sleet or rain in southern sections. Rainy and snowy weather will continue over the region to some degree through Saturday. A shift in the pattern will take place as a low pressure system develops in the mid west and begins its trek toward New England. Passage of the low will bring a little warmer air, and make mixed precipitation more likely Saturday. High pressure will build in behind the departing low Sunday with sunny and windy weather. === The weather observed at WHITEFIELD, NH at 08:52 AM EST was: === The skies were mostly clear.
