Discussion
On Friday, a “clipper” low pressure system will drop to the south and east from the Great Lakes region at the same time low pressure starts to form over the western Atlantic Ocean. These two systems may combine to produce rain and/or snow showers in the region early Friday and then snow showers – perhaps even a period of steadier snow – from later Friday into early Saturday. Accumulations of snow on the order of a coating to a couple of inches are on the table by early Saturday morning.
As the low pressure system intensifies on Saturday and pulls off to the northeast of here, the coldest air of the season so far will pour into the region for the latter part of the weekend and early part of next week. Temperatures on Sunday will be confined to the middle 20’s for afternoon highs – the coldest day so far this season - and the overnight lows by early Monday morning could be near 10 degrees across many suburban locations.
