*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…near zero degrees likely 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 or early tomorrow night. 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 are likely to be near zero degrees with a minimal warm up expected on Thursday afternoon.
