Wednesday a damp one for the coast A frontal boundary approaches the state from the west. Low pressure forms out ahead of the front that will move through the Gulf of Maine into Maritime Canada. For the mountains of western areas up into the Allagash, this appears to be a light snow event. A light rain/mix is possible over the foothills on up into southern Aroostook, rain elsewhere. Southern areas see the shower activity end early afternoon, early evening for Washington County. A few flakes are possible on the backside of the front, but nothing to cause any real concern.  The main area of precipitation is over coastal areas. Low pressure enhances as it travels into the Bay of Fundy, bringing higher amounts DownEast.  Any snow accumulations will be light in nature. This graphic also includes potential for snow shower activity Thursday night into Friday morning.  High temperatures for the day appear to range in the 30s for the mountains and north, 40s to around 50 for the shorelines. As the front passes, temperatures steadily drop off in the mid-afternoon into the evening.  It will be on the breezy side as a west/northwest wind picks up which should help dry any damp areas out. With the cold air coming in, the wind chill will certainly be noticeable. If there is patchy ice potential, it is possible for the MidCoast into DownEast areas where the heavier rain amounts are expected to fall. This would occur late Wednesday night.  All areas appear to start Thanksgiving Day in the 20s, with wind chill indices in the single digits to teens for the mountains and north. Thanksgiving a chilly one The day will feature some high clouds around as a weak warm front tries to nose into the area which may milk the sun a bit. A weak clipper system will slide through the region Thursday night which may bring some light snow to the mountains and north, and flakes possible elsewhere.  Temperatures for the day range in the 20s to near 30 for the north and mountains, with 30s elsewhere. These are running between 5° - 8° below our season normals. No issues for Black Friday For those heading to the malls for the official kick off to the Christmas shopping season, there will be no weather related issues to be concerned with. A mainly sunny day, with highs in the 40s for the coastal regions, 20s and 30s for the mountains and north.
I am tracking the system over Manitoba and the system near Florida for the second half of the weekend. Saturday may bring a chance for snow or rain showers. Sunday may bring the same. I will have more details on that on Wednesday. - Mike |
