A series of several strong cold fronts will surge south through the area in the first week of the new year. High temperatures on Monday, January 2nd, are likely to be about 15 to 20 degrees colder than what was observed on New Years Day in the wake of Sunday's first cold front. Breezy northwest winds will set up across most of the area, with highs in the mid-to-upper 50s. The secondary cold front, and the shallow arctic air mass, will arrive Monday evening.

The cold air mass will linger on Tuesday. High temperatures may struggle to reach the low-to-mid 40s. Combined with breezy northwest winds, the wind chill during the warmest part of Tuesday afternoon will be in the upper 30s to around 40 degrees. As high pressure settles into the region late Tuesday, winds will decrease and temperatures will drop quickly as the sun sets.
