We’re living in a snow globe this morning as light lake effect snow showers continue due to cold air advection and northerly wind flow caused by large Canadian high pressure ridge to our north. While little accumulation is expected over much of the area, southern Cook County and Lake County in NW Indiana are favored for some accumulating snow. This set up will continue tonight into tomorrow, but as some drier air filters expect some partial clearing overnight inland, as clouds and snow showers continue along lakefront areas into tomorrow with partial sun inland. Still cold through the weekend, but more sun and less wind on Sunday, the better of the two weekend days. Monday into Tuesday brings next chance for more snow to the metro area as fairly impressive clipper approaches from the northwest. Guidance has varied in placement and timing on this feature the past few days, so this forecast comes with a caveat. Future runs may alter current thinking. For now looks like decent band of snow will set up here, or close by with some accumulation likely. If snow does arrive, looks to be just after Monday morning rush hour ending late day, then a break before next wave moves just to our southwest, but close enough to keep light snow chance into Tuesday. After that high pressure ridge brings dry conditions and moderate warming trend Wednesday into Thursday, which will more than likely be warmest day in the extend forecast with mid 40s expected. All systems good.
