Cold high pressure over the Upper Midwest/Ohio Valley will slowly move eastward off the East Coast by Saturday, February 2, NWS forecaster Ziegenfelder noted January 31.

Temperatures will slowly begin to moderate as the air mass slowly warms. The wind chills will range between -45 to – 28 °C (-50 to -20 °F) over parts of the Upper Midwest on Thursday.

The cold air and upper-level energy will aid in producing lake effect snow, that will be heavy at times, downwind from the Great Lakes through Friday, February 1.

Meanwhile, upper-level energy over the Northern Plains will move southeastward to the Ohio Valley by Friday and off the East Coast by Saturday, February 2.

The energy will aid in producing light snow over parts of the Northern Plains that will move into the Ohio Valley by Thursday evening and into the Ohio Valley/Central Appalachians by Friday morning. The snow will move into parts of the Northern Mid-Atlantic overnight Friday, ending by Saturday morning.

In addition, a front will develop over parts of Central Canada overnight Friday moving southeastward into the Upper Great Lakes by Saturday morning. The boundary will aid in producing light snow over parts of the Upper Great Lakes/Upper Mississippi Valley overnight Friday into Saturday.
