High pressure centered over northern New England brought the region some bone-chilling cold last night and early this morning. Winds shifted to the south and southeast as the high pressure area drifted east of our region, and temperatures are now slowly rebounding thanks to the wind shift and some early January sunshine. Fair weather is forecast today, and overnight tonight. Low temperatures will not be as cold as last night’s lows tonight, though it will still be quite cold.
A storm system, organizing over the southern Plains will move toward the middle Mississippi Valley through the day Saturday, and into the Ohio Valley through the day on Sunday. This system will be associated with a potent Arctic cold front. However, unlike the previous storm, the low pressure center will remain to the west and north of the Capital Region. This will allow for relatively warmer air to be pumped northward ahead of the approaching frontal boundary, bringing our region some above freezing air for Sunday. Of course, we will run the increased risk of precipitation as well, but the majority of the precipitation should be rainfall over the area as temperatures rise during the day on Sunday, and essentially remain steady overnight on Sunday. Some patchy, locally dense fog, may occur on Sunday night as well.
Our brief soiree into milder temperatures will be gate-crashed on Monday morning as the Arctic cold front blasts through the region during the morning hours. What will likely begin as rainfall over the region early Monday morning, will be slowly replaced by a transition to some light snow as the front passes, and temperatures drop through the 30’s during the day on Monday. Brisk west and northwest winds will kick up. These winds will remain with us through the next couple days as some bitter cold air pays the region a visit yet again through the midweek period.
The remainder of the week sees another week and unimpressive system pass to our north on Thursday, followed by an area of high pressure building in for the end of the week. This high pressure moves offshore over the Atlantic for the coming weekend and brings a moderation in temperatures back to seasonal averages for this time of year.
