January is on track to end on a dry note for most of the area, as a developing snowstorm south of the area brushes coastal locations with light snow on Wednesday, followed by a more sustained warming of temperatures into the 30s starting on Friday. Light rain and possibly snow are expected for Saturday-Saturday night, likely ending in time for the Super Bowl on Sunday evening, although signals for a more significant system exist towards the middle of next week (Image credit: NCEP MAG).

Today – Friday: Cold Pattern Ends This Week
The significant cold that has affected the region in waves starting in early January, leading to the coldest month since January 2009 and the most number of single digit lows in a month in NYC since January 2005, is on track to end this week, but not before a final round of cold today. A strong arctic air mass entered the Midwest again over the last 1-2 days, with high temperatures well below zero, although the models overestimated the intensity of the cold air mass entering the Midwest, and as a result have backed off the magnitude of the cold over the region. Temperatures today are expected to reach the 15-20 degree range for most of the area with partly sunny skies and a breezy west wind, leading to wind chill values in the single digits.

The cold front that pushed south of the area yesterday will stall near the southeast US, where a low pressure will develop later today into tomorrow, leading to a snowstorm affecting locations unusually south, including Georgia, South Carolina and North Carolina, with ice and freezing rain extending into coastal locations and even northern Florida. As the low pressure tracks northeast, most of the snow will stay offshore, although light snow showers are likely to brush Long Island, with up to a coating of snow possible in far eastern Long Island. Partly to mostly cloudy skies are otherwise expected with highs in the low to mid 20s. A gradual warm up will then continue into Thursday and Friday, with highs reaching the upper 20s-low 30s and the low-mid 30s, respectively.
