A dry Sunday for most areas, a rainy Monday for all Looking at all of the features going on in the region early Sunday morning, the one that stood out to me the most is the upper low over Labrador. It has run into a roadblock upstream and backed in to the southwest. The weak area of high pressure near the state is doing its job drying out the air column. The combination of the two has altered the forecast precipitation amounts to a lower amount, but we'll take what we can get at this point.  Sunday 6 AM to Monday Midnight - This not radar here. I've opted for the 1-hour forecast precipitation idea from the NAM3km due to the dry air around from the surface high. I don't expect much in the way of some sprinkles or a light shower across southern areas through the day. Northern areas see cloud cover increase during the day, and the sun will benefit warmer temperatures in the 50s, where southern areas may not get out of the 40s,  Monday Midnight to Tuesday Midnight - Dry air from the high keeps northern areas dry until around midday on Monday, with showers prevalent elsewhere. As the surface low tracks into the Gulf of St. Lawrence, it shuts off steady rainfall, but there could be some areas of patchy drizzle and fog around southern and eastern areas until Monday night. As the cold front slips through, I expect a chilly northwest breeze to develop, with 20-30 mph range. Expect windchill values in the 20s over western and northern areas to the low 30s heading into Tuesday morning. Light precipitation in the form of valley rain showers and snow shower for the mountain tops along the Quebec border region persist through Tuesday and shut down on Wednesday as the upper level low and associated trough move into the North Atlantic.  Given the dry air around, precipitation amounts have been reduced. Higher elevations have the best chance to pick up 1" of rainfall that will mix with and change to snow as temperatures crash Monday afternoon into Tuesday. I am still thinking 1-3" of snow for the higher hilltops by the time the snow machine turns off by Wednesday, with Katahdin and the Whites in the 3-6"+ range. I do not expect any travel issues, but for those hiking, be aware of it. Without your support, there is no PTW Always have MULTIPLE ways to receive weather alerts.
