Monday will start off mostly cloudy with the colder air settling in across the Commonwealth. Some light snow will likely develop into the afternoon, and especially evening hours with most areas seeing just a dusting. The timing of the snowfall will likely be around the evening commute, so some slick spots are possible, but again, accumulations will be slim. Highs today will be in the lower to mid 30's. Winds could gust around 20 mph at times.
The real arctic chill builds in for tomorrow and Wednesday when afternoon highs will be closer to 20 degrees. Expect a few flurries from time to time, with blustery conditions. Winds could gust over 30 mph through Thursday. The best chance for flurries would be, as usual, northwest of Harrisburg. Lake effect snow showers typically don't amount to much for our region, but there could be a fresh coating up toward Lewistown and Mifflintown through midweek.
As we approach the weekend, a storm system will try and develop for Friday. At this point, temperatures would point toward a region-wide snowfall, but it is way too early to talk about any potential snow totals. Suffice it to say, it will be a cold week ahead, as we start to wrap up January. We have definitely settled into a winter pattern.
