Today's update is presented by Crowe’s Restoration of Arundel. For emergency fire & water damage (pipe bursts), mold, or biohazard issues in western and southern Maine, call them at 207-467-3152, and thank you for supporting PTW! Another round of Arctic air moves in As I worked on this discussion at 5:10 AM, a snow squall warning was issued by NWS Caribou for parts of northern Maine. It's rather odd to get snow squall warnings at that hour as they are convective in nature and require some heat and lift that is more common in daylight. This is a clear indicator that this Arctic front means business. While the short term ideas show the squall line breaking down as it transcends into the region, the risk is there for locally heavy snow showers or a squall until late morning. Stay alert for rapidly changing road conditions. By early afternoon, the front will be offshore, and cold will be pouring in from the north with the assistance of high pressure to the west. The daytime highs happen in the morning hours. Expect temperatures to fall in the afternoon, with s stiff breeze to slap a bitter cold wind chill in your face later in the day. A cold weather advisory may be issued for the mountains and north for the overnight as the wind chill may dip into the -20s. An Alberta Clipper passes through the region Wednesday Wednesday Midnight (05z) to Thursday Midnight (05z) - Snow works in from the west in the wee hours of Wednesday and moves far enough east where the morning commute could be affected. While snowfall appears generally light in the morning, the fluffy nature of it is likely to create slick travel conditions. While northern areas sit this one out other than a few charity flakes, blowing snow may cause localized issues there. The snow gradually tapers off over the west and east in the afternoon. The concern for the south for the evening commute comes from the potential of weak low pressure forming over the Gulf of Maine that could bring localized heavy snow and/or a squall as the system departs. This could cause concerns for the evening commute. The bottom line is to expect a slow commute on both ends of the workday.  Along with the falling snow comes the wind that will blow it around which will reduce visibility along the coast. There could be lulls in the breeze at times, but as the clipper and developing ocean low departs, the wind picks back up in earnest Wednesday night into Thursday morning. With the new fallen snow, brief whiteout conditions are possible and slick roads are expected into the overnight as northwest winds increase and gust 20-35 mph across much of the area. A frigid start to Thursday While it may not be as ridiculously cold as it was last week, it will be cold enough. Expect wind chill values in the double digits below zero over the interior all day as the biting wind continues. The breeze appears to diminish Thursday night. Snow showers are possible overnight into Friday as a weak warm front moves into the region. Questions remain about Friday into Saturday There is still no clear picture as how Friday is going to play out. The assorted guidance idea and ensembles are having a hard time with the timing of the phase between the polar jet and southern stream. At this point, the coast gets the best chance of something, but precipitation type and amounts are still to be determined. Stay tuned!
