A brief interlude of southwest winds helped temperatures sneak their way up to around 40F Wednesday afternoon. However, a cold front passed over the area late in the afternoon and shunted the “milder” air out of the region and sent temperatures tumbling overnight. Readings fell to the lower and middle 20s across most of the Cape and will be slow to recover today, despite plenty of sunshine. Highs should top out in the upper 20s to around 30F.
A weak, fast-moving weather system will approach the area tonight and pass through the region Friday morning. This system doesn’t have much “juice” to it but will spread a shield of clouds and areas of light precipitation eastward through the Northeast and New England late tonight and through the first part of Friday. As a result, we can expect clouds to thicken up tonight and for some spotty flurries and snow showers to develop after midnight. This light activity will continue into Friday morning before somewhat milder air invades the area and allows for any light snow shower activity to transition to some light rain showers. There could be a light coating of snow in spots and that may result in some slick roads first thing Friday morning…especially given the very cold ground/surface temperatures. So keep that in mind if you are headed out early Friday morning.
Behind Friday’s weather system, a reinforcing surge of cold air will spill into the region, setting us up for a Saturday that will be very much like today – dry but quite chilly with temperatures again struggling to crack the freezing mark.
Beyond that, attention will turn to a far more substantial weather-maker that will reach the region Saturday night and impact the area throughout the day on Sunday. Initially, this storm center will bring us a period of accumulating snow Saturday night…but a transition to sleet and rain will occur relatively quickly and we can anticipate a wind-driven rain throughout much of the day on Sunday.
