Cloud cover as result of lake effect processes off of Lake Ontario will grudgingly give way to some intervals of sunshine this morning. Clouds will quickly increase once again by this afternoon, however, as a duo of low pressure systems begins to impact the Capital Region.
A disturbance over the central Plains is forecast to move south and east and join forces with a moisture rich area of low pressure moving north and northeast from the Gulf of Mexico. Snowfall will begin this evening as the region experiences the effects of the central Plains low pressure area. As the Gulf of Mexico system integrates northward through the overnight hours, and lends its moisture to the scenario, a steady, fluffy snowfall should result. The snowfall looks to last through the day on Thursday, and into Thursday evening before slowly tapering off Thursday night and early Friday morning. Significant snowfall accumulations are expected in the Capital Region, with perhaps a bit more further south, and a bit less further north.
Friday into the first part of the weekend will be dominated by cold Canadian high pressure. The combination of this high pressure, clearing skies, light winds, and a fresh and deep snow pack will send temperatures plummeting, most likely well below zero on Friday night. As the high pressure area moves east of the region on Saturday, and a southerly wind flow slowly picks up, temperatures will begin a slow upward trend, though it will still remain very cold.
Another weather system looks to approach the region to close out the weekend and open up the first full work week of 2014. There are still quite a few ambiguous details to be sorted out concerning this storm’s track and evolution. It looks to be mainly a frozen precipitation event at this point in time, and it also looks to be followed by another bitterly cold airmass. Stay tuned for later details.
