Growing-up here in the Bangor area, I remember many winters when we would have sub-zero temperatures for many days in a row. That's not the case with our latest cold snap, as we've got some milder air coming to the rescue tomorrow. Thanks to a wind shift (from northwest to southwest) some milder air will flow into Northern New England tomorrow, with most locations topping-out well into the 20s. Not exactly a heatwave, but certainly more tolerable than the artic air we've had in place lately.
Look for some cloud cover with some northern snow showers Friday as an area of low pressure tracks to our north, with sunshine and brisk conditions returing for Saturday. The clouds will return on Sunday with a risk of snow showers Sunday as another low pressure system influences our weather pattern.
Looking to next week: a broad southwest flow will bring some fairly mild air (30s) by mid-week. We may even see some rain showers later in the week mixing with some snowflakes.
