A mild day aheadSATURDAY - The warm front that passed through early this morning brings seasonably mild temperatures with partial sunshine. A westerly breeze helps warm things up through midday. A weak cold front passes through in the afternoon, cooling things down as the wind shifts to the northwest. Wind gusts range from 15 to 25 mph. High temperatures range from the upper 40s along the Quebec border to the low 60s along the south coast. SATURDAY NIGHT - The sky clears away from the mountains, and the wind diminishes. Overnight lows range from the teens in the Allagash region to the low to mid-30s along the shorelines. Light mixed bag to rain Sunday into Monday Clouds increase Sunday with an east/northeast breeze picking up through the day. Outside of a chance of an outflow shower in the mountains, the daylight hours are precipitation-free. A neutral trough that has set up a weak area of low pressure to the south of New England rides along it. The low is in the early stages of development and consequently does not have much to offer in terms of precipitation amounts.  A cold air damming signal has been present for the past couple of days, and it continues, but it is not alarming. The high to the north is on the weaker side, and with the low on track to enter Penobscot Bay/DownEast areas and track north, I don't expect any surprises with this one. Temperatures are marginal, varying by a degree or two Celsius, in the higher elevations. The east-northeast wind flow off the ocean brings in warmth from the 50° water. This is another progressive system. Precipitation begins overnight Sunday and continues through Monday, ending for most areas Monday night. Snow showers in the mountains are expected to continue into Tuesday.  The bottom line is that this is more of a nuisance event for the interior. I don't expect any issues, except for a few slick spots, which are possible on Monday morning, especially closer to the Quebec border. Snowfall appears minimal, with the Allagash region potentially picking up an inch or two that will wash away. Some light ice is possible in the transition, but that will melt away as temperatures rise. Liquid equivalent precipitation amounts are generally expected to run between ¼-½" through Monday morning, with an additional ¼-½" possible in the form of rain through Monday night. Below-normal temperatures with weak clippers passing through are expected to persist throughout the remainder of the week, bringing snow showers to higher elevations and light rain showers to the valleys. I will update again on Sunday morning. Family owned emergency service The PTW Weather Wall updates 24/7 Your financial support keeps the lighthouse lit |
