Lake effect snow showers and squalls will organize and intensify today as cold air continues to pour across the lake. Several inches of snow could accumulate across the favored snow belts of Erie and Crawford counties and a Lake Effect Snow Warning is in effect for these counties.
It will be windy today as well with areas of blowing and drifting snow expected. Some locations will experience local white-out conditions.
The snow showers will gradually diminish tonight as drier air overspreads the region. Thursday will be mainly dry with just a slight chance of a few snow showers or flurries.
A storm over the Plains States on Thursday will track toward the Great Lakes on Friday. Clouds will increase across the area Thursday night with precipitation arriving by Friday morning. This precipitation will likely fall as snow.
During the day on Friday, milder air will stream northward across the region. This will cause the snow to become mixed with sleet and freezing rain, possibly changing to all rain by Friday afternoon. Some accumulation of snow and ice is possible.
It will remain unsettled through the weekend, but milder temperatures should keep most of the precipitation in the form of rain.
