The weather pattern over the weekend was dominated by what Meteorologists refer to as 'Northwest Flow'. This means the jetstream is positioned from northwest to southeast across the United States. Storms systems, known as Alberta Clippers, are usually common within this type of weather pattern and often times bring fluffy, dry snow with them.
By midweek a shift to more of a zonal flow (west to east pattern) within the jetstream will occur meaning any storm system that tracks across the Plains and Great Lakes will likely have more of a mild, Pacific influence than an Arctic one. This is exactly what our next storm system will have that will move in late Wednesday night. A mix of rain/snow will occur likely after midnight Wednesday as overnight temperatures rise and continue into Thursday. Temperatures will try to rise above freezing at the surface but with the recent snowfall may fall short by Thursday afternoon meaning a slushy accumulation of snow will be possible as a cold front moves through. We may end up with a couple inches of slushy snow by Thursday evening.
