Detailed Discussion

Cool, unsettled weather this weekend might not have been as pleasant for outdoor plans, but the showers encouraged spring’s green to paint more of the landscape, though not climbing up the slopes all that quickly, with snow whitening the mountain peaks. Skies cleared for a time last night, but additional clouds and some scattered showers have been working back in from the west since midnight, the first in a series of weather systems that will create daily changes through this week. The source of our unsettled weather this weekend has deepened into an intense low pressure system in the Gulf of the St. Lawrence, lifting northeast toward Labrador this morning, with warm high pressure well south, off the southeastern US coast, while low pressure is tracking east through Ontario, north of the Great Lakes. The high supplies a milder west wind, while the storm to our west pushes a minor ripple in the atmosphere through, responsible for the periods of clouds and localized showers this morning. This minor disturbance decays, allowing periods of sun to develop as the showers peter out. The intervals of sun should encourage thermometers to climb to the 60s in most locations this afternoon, a few upper 50s in the far north with more morning showers and less sun this afternoon. The storm north of the Great Lakes curls northeast and north tonight into Tuesday, steering a cold front around it, so that it approaches from the northwest tomorrow. Ahead of it, the warming trend continues, offering some 70s tomorrow afternoon. At the same time, as the cold front edges closer, clusters of clouds will build, leading to localized showers, and perhaps an isolated afternoon thunderstorm, more likely through NY, Quebec, and into northwest VT closer to the front, and less likely south and east. This front slows down Tuesday night into Wednesday, which will steer a parade of showers and occasional rain east along the front. The question is where the front will be located. At the moment, the rain showers are most likely through the eastern Adirondacks, VT, the Berkshires, and from the Lakes Region in NH north into the Eastern Townships, with cooler temperatures north of the front, in the 50s, and some warmer 60s south of the front. These details will be refined as we develop a better idea as to the position of the front. This continues to be a factor later in the week. Latest guidance sends the front south of New England, resulting in cool temperatures, and a few localized showers, mostly in the afternoon with the marginal warming of the atmosphere each day. Should the front remain closer to the region, so will the clouds and showers, particularly with another wave of low pressure and enhanced showers riding along the front. Regardless, the air behind the front is cooler, which means highs mostly in the 50s through northern areas Thursday and Friday. In southern areas, 50s are also expected, either with greater push of cool air, or with more clouds and showers keeping temperatures in the 50s.
