Enjoy your outdoor activities.
Cold air advection will continue today, Friday, as an upper-level low lingers over the eastern Great Lakes. A north to northeasterly flow combined with cooler air will support lake effect precipitation, with a few snowflakes occasionally mixing in across northern areas. High pressure builds in on Saturday, keeping conditions dry across southern portions of the region through the weekend. However, a passing shortwave may bring light precipitation to northern areas on Sunday. Friday will be the coldest day of the forecast period. Temperatures will gradually recover, with highs returning to the 50s across southern areas by Saturday and expanding northward by Sunday into Monday. Predominantly north to northwesterly flow throughout the forecast period is expected to keep fine particulate concentrations in the Good range.
