Lake effect snow bands continued to impact portions of the western Mohawk Valley early this morning. A westerly wind was responsible for the longevity of this band, as the cold breeze blew over the relatively warmer waters of lake Ontario, feeding the band necessary moisture. Through the morning hours today, winds are expected to veer to the west-northwest, which should aid in shifting the band southward, down the Mohawk Valley and into the Capital Region. This situation will be further aided by a weak and fast moving area of low pressure over northern Canada, and a weak cold front. Some very minor accumulations are possible over the Capital Region, perhaps a coating of snow from time to time.
Clouds are forecast to hang tough tonight, as another fast moving system approaches from the upper Great Lakes. In the meantime, an area of low pressure is forecast to develop over the Tennessee Valley region early Tuesday morning, and move to the vicinity of the Delmarva Peninsula by late Tuesday morning. This system looks to make a beeline out to sea by Tuesday night, being well southeast of Cape Cod, and thus not posing a threat to the Capital Region and vicinity. The westerly wind flow over the Capital Region will continue to be prevalent through this entire period, and thus, the lake effect snow bands should tend to migrate back to the north of the region.
High pressure briefly builds into the region by Thursday, before another system approaches for the weekend, bringing the threat of a mixed bag of precipitation.
