ECMWF Snowfall Forecast(10:1 Ratio) : Forecast ending Friday 1/7/22
❄ We are tracking significant changes in the overall pattern across the United States as we head deeper into the New Year! Strong troughing in the Western States, which led to record warmth in the east during all of December, is showing signs of breaking down and heading east. With Heavy Snow blanketing parts of Appalachia and the Mid-Atlantic region today, another storm system will drop south from Western Canada on Tuesday. This storm has the potential to deliver accumulating snowfall and other Winter Weather hazards to areas that have been void thus far in the season.

A developing low pressure system in the Tennessee Valley is likely to deliver Wintry Weather to the Ohio Valley by mid-week.
While the storm responsible for this week's snow potential is currently located over portions of the Pacific Ocean, models have come into better agreement overall, with the main outlier still being the GFS. This model has seen poor run-to-run consistency after being the lead model during the forecasting of the current Appalachian storm, but this morning's 6z Operational model package is showing signs of better agreement.

Other reliable models continue to indicate that heavy snow could fall for many across several states, especially during the day Thursday. Additional snowfall is expected across eastern Ohio and Pennsylvania Thursday night as the system pulls into the Northeast.

We will monitor this system over the next 48 hours and provide specific details as they become available.
