Discussion

Very cold air has gripped the nation from California to Texas to the Great Lakes, but here in the East, mild air has made a return. In fact, today will be the mildest day of the week, but this warm up will be rather short-lived. After a day with highs near 65 degrees, a strong cold front will slide through the region by early tomorrow and reverse our temperature trend. In fact, temperatures may peak in the morning on Friday and then drop slowly during the afternoon hours. This gradual transition from mild-to-cold will be accompanied by periods of rain from tonight into tomorrow night. It could get just cold enough by late tomorrow night for the rain to mix with or change to sleet and/or snow before ending in some of the northern and western suburbs.

After a dry Saturday afternoon and early evening, attention will turn to the Deep South as moisture will head our way from that part of the country at the same time strong Arctic high pressure settles in to our north. The end result could be an extended period of ice in this area as there will likely be below freezing temperatures at ground level, but above freezing in the upper parts of the atmosphere. The precipitation is likely to change to plain rain by Sunday night or early Monday and then we’ll be looking to our northwest for the arrival of another very cold Arctic air mass on Tuesday.
