A cold upper level trough will continue to dig into the northeastern United States today. A disturbance will rotate around the back side of this trough tonight and Wednesday reinforcing it.
At the surface, a cold westerly flow will continue today and tonight with areas of light snow and snow showers across much of the region. The most persistent snow showers will occur downwind of the lakes in the favored snow belt areas. The highest snowfall amounts will likely fall to the east of Lake Erie across northwestern Pennsylvania and the ski country of western New York. In these areas, several inches of snow could fall through tonight.
The surface flow will shift to the northwest Wednesday night and Thursday as the trough axis shifts to the east. Lake effect snows will reorient in the northwesterly flow impacting areas further west and inland including northeastern Ohio.
Through Thursday, temperatures across the region will remain well below average for this time of year making for a cold start to Spring.
The lake snows will finally wind down Thursday night and Friday as high pressure briefly builds across the region. Temperatures will moderate a little by the end of the week, but still remain below average.
