Although the calender reads April 5th, it certainly looks like mid-winter at this mornings first glance out the window. It started with low pressure near the Great Lakes, which spawned a low in the mid Atlantic along a frontal boundary yesterday. The coastal low deepened as it tracked to Nantucket through the early morning hours. The system brought significant snow to most of New England, with the heaviest snow falling overnight. So far, many locations in the foothills and mountains were approaching a foot of snow. As of 400 am, hollis reported around a foot, Auburn had 10" on the ground, around 9" here at the office in Gray Maine, 8" at Cape elizabeth and Waterville, and 7" in durham and boothbay harbor. This is just to name a few reports, with some additional snow accumulation expected through the early morning hours. Radar shows moderate to heavy snow across nearly all of Maine, and northern New Hampshire. Snowfall has tapered off across most of southern New Hampshire, as the area of heavy snowfall gradually moves north and east. Temperatures were in the upper 20s north, and the lower 30s elsewhere, with all locations cold enough for snow, as we remain in the cold sector of the storm. The low will track across eastern Maine today. This will cause snow to taper off through this morning, from southwest to northeast. However, snow showers will linger in the mountains through the day. Temperatures will remain cool today, with highs only in the 30s. The low will move into northern Quebec late tonight and Friday. Snow showers should linger in the mountains through Friday, with a chance of a snow shower making into the foothills as well. Highs will continue to be on the cool side, ranging from the lower 30s in the mountains, to the lower 40s in far southern New Hampshire. Looking ahead to the weekend, low pressure will remain across Quebec, with another area of low pressure tracking well to the east, intensifying through Sunday. Although significant snowfall is not expected, can't rule out a snow shower on Sunday. Highs will be in the upper 30s in the mountains, up to the mid 40s in southern Maine and New Hampshire. === The weather observed at WHITEFIELD, NH at 07:52 AM EST was: === The skies were mostly cloudy.
