    Parole Hearing for Man Convicted of Killing Teen in 1981

    A man convicted of killing his teenage friend in 1981 is asking to be released from prison. Meanwhile, the victim's family is calling for George MacNeill to remain behind bars.

    (Published Tuesday, Jan. 15, 2019)

    With a First Alert issued by our weather team for both Friday morning and Sunday, we’re on borrowed time with quiet and dry weather. But for now, New England remains cool and quiet.

    A light wind Tuesday couples with sun and high-altitude clouds to make high temperatures in the 30s actually feel like we’re pretty close to that in the absence of any significant wind chill. Tuesday night’s clear sky and light wind will allow temperatures to drop into the teens but, again, no significant wind chill is expected.

    A moisture-starved storm system moving along the Canadian border Wednesday will pull a cold front toward New England, inducing a strengthening southwest wind that will gust 25 to 30 mph Wednesday afternoon. This system will also be ushering in enough milder air to nudge temperatures into the 40s.

    Of course, a busy wind negates some of our warming, leaving wind chill values in the 30s at the warmest time of day Wednesday. Clouds return Thursday and snow develops overnight Thursday night.

    This snow will be continuing through Friday morning and make for a slick commute before a change to rain progresses from north to south across Southern New England. This rain will continue from morning to midday before precipitation shuts down for the afternoon.

    We’ll dry out Friday afternoon through Saturday, then our next storm comes calling – an energetic storm loaded with both Pacific and Gulf of Mexico moisture that ensures heavy precipitation across the area and another First Alert for Sunday.

    The key on Sunday is exact placement of the rain/snow line, which may end up as far north as Central or Southern New Hampshire for the heart of the event depending on storm track, but regardless of where it lands, extremely heavy snow will fall north of the track, followed by cold air for the MLK holiday.
