*Extreme cold is headed to the north-central US – potentially historic for places like Chicago, Illinois - and it will spread to the east coast at mid-week…single digits here by Thursday morning.* High pressure is in control today as we begin a new work week, but the quiet weather will change on Tuesday as a strong cold front slides toward the eastern seaboard. Low pressure will form along the cold frontal boundary zone on Tuesday and a mixed bag of precipitation here is likely to change to all snow later in the day. Accumulations are possible by later tomorrow evening on the order of 1-3 inches and travel may become hazardous as temperatures fall. An Arctic boundary will slide through on Wednesday with strong wind gusts and possible snow showers - perhaps even a heavier snow squall. The brunt of the Arctic blast arrives on Wednesday night and temperatures by Thursday morning should be in the single digits with a minimal warm up expected on Thursday afternoon.
