Berkshire County Forecast-Monday, November 4

SummarySurface high pressure is cresting over the region today. This made for an ideal radiational cooling night last night (clear, calm and dry) with temperatures bottoming out in the teens. This system was also responsible for the beautiful late fall/early winter day today. As it drifts to our east over the next few days, a return southerly flow around the backside of the high will bring milder temperatures but also more cloudiness into the region. We will remain dry until Thursday, when a surface low pressure system will pass well to our north, through the Great Lakes and into Quebec, dragging its trailing cold front through with some rain showers. Surface high pressure will then return for the end of the week and at least the first part of the weekend. This repeating surface pattern, and the jet stream wave pattern responsible for it, have been very persistent for the past several weeks.
