Temperatures will quickly rise, peaking near freezing Sunday afternoon. On Monday, the high will exit the Atlantic coast while a large northward budge of the jet stream occurs across the Eastern U.S. which will set the stage for much warmer air to the return to the East early this week. Low pressure will travel from near Lake Michigan Monday morning to Lake Ontario by evening, while a warm front attached to the low approaches from the Ohio Valley.

Cold air in the lower part of the atmosphere will remain stubborn east of the Appalachians, however, which will affect our weather in two ways. First, it will allow for a brief period of ice on Monday morning, which may be mixed with snow north of the city. Any frozen precip. will turn to plain rain before midday, turning to liquid quickest in the city and points south, and lastly NW of the city. We expect that the northern suburbs could pick up a coating of snow early Monday morning before turning to ice and then rain. Untreated roadways will become slick.

Tuesday will feature milder breezes from the south, as temps climb into the 50s. Patchy fog and a few drips will occur. Active breezes from the southwest will then bring unseasonably warm air on Wednesday ahead of a cold front which will move from the Ohio Valley in the morning to the East Coast at night. The first half of Wednesday should be dry as temps climb well into the 60s in many places, likely the warmest weather since last November! Heavy rain, with some thunderstorms will occur in the evening. Some of the storms could produce damaging winds and enough heavy rain to cause flooding in poor drainage areas.
