A cold front, of Arctic origin, will pass through the region during the afternoon and evening hours today. Some snow showers will likely develop along and in advance of this frontal system. Lake effect clouds and showers may persist for most of the morning across the north country and favored locations in the lee of Lake Ontario where several inches of snow are likely to accumulate.
High pressure will nose into the region Thursday morning, however, a very cold airmass will be in place, and with a persistent westerly wind flow in the low levels, lake effect processes should be optimized to the north and west of the Capital Region once again. A chilly end to the work week is in store, as temperatures struggle to escape the 20’s during the daytime hours despite a mix of sun and clouds. Overnight lows look to be quite chilly as well, dipping into the teens, except for those areas that see accumulating lake effect snow showers, where overnight minimum temperatures may fall into the single digits above zero.
The weekend continues to be monitored closely for the potential of a winter storm to impact the region. Another Arctic boundary looks to cross the region on Friday. Although this front does not look impressive with regard to moisture, it will play an important role in the upcoming weekend’s forecast as it appears to stall to our south and interacts with a developing area of low pressure that moves from the Four Corners region on Friday to the lower Mississippi Valley on Saturday, and the mid Atlantic coast by Sunday morning. Strong and cold high pressure anchors itself to our north through this period, and thus, any precipitation that falls over the weekend may be predominantly in the form of snow. Stay tuned for further details in future forecasts.
Behind the weekend system will come a true taste of ‘Old Man Winter’, as a bitter cold Arctic airmass infiltrates the area with well below normal temperatures.
