Today, I have been sifting through the data and the guidance as of the 00z runs 10/3 and they are showing me the signs towards winter are upon us. New England weather is rather volatile the further we get from the summer and we get deeper into the season of Fall and then winter. As the holidays approach we are reminded how lucky we have been to live life as long as we have, and to have people who care about us in this world. As the holidays approach we are reminded of this constantly. As winter approaches abruptly and the only way Nature knows how, we get warning signs that the weather machine is ready to change gears and this is what I am seeing on the guidance this morning. There is rather strong agreement that a clipper will develop a secondary low off the coast of Cape Cod and Nantucket (ACK) as we head into the weekend. This system will carry a cold air mass on the north side and then northwest side and bring a change of temperatures to the region from the backside winds. Before that happens, we will experience spotty rain, until you are north of Concord, NH where rain will become more steady and then changeover to snow as one heads into the mountains of northern NH/VT/ME and the mountains of this region in the weekend. Saturday will be rather raw and spot showers at times, and then Sunday will be quite beautiful and rather chilly compared to what the last few days have given us.
Also, another sign of the change in seasons is the rather rapid build-up of cold deep arctic air masses into northern Canada and then into the central and southern Canadian Prairies. This will begin to dive into the northern third of the US, above 40N from MT to ME as we head into the mid-month period and then the end of the month and beyond. Rather active weather pattern will begin to impact the US as multiple troughs will swing through the northern tier, this is rather common in neutral ENSO patterns. I will have another update after the 12z EURO if something changes in the guidance.
