A quick moving but potent storm system will impact Saturday with cold, soaking rain. We'll be on temperature watch in the upper levels of the atmosphere as they will be flirting with freezing. The strong dynamics with this system will help pull that cooler air down into the region. Starting as rain, the cooler air settles in throughout the day and a mixture of rain/snow is possible Saturday afternoon into the evening. A slushy accumulation is possible, but due to the wavering track and uncertainty of the overall warm late April scenario, snow totals are tough to pin at this stage in the game.
The possibility is there, especially for southern Minnesota for the opportunity. Checking the model ensembles, we're seeing widely varying results for Rochester, due to the reasons mentioned above.
Regardless of rain/snow, Saturday will be less than desirable as a wind kicks up late, temperatures fall and the damp feeling that is being presented.
Into Thursday, the picture should become far more clear as to the impacts to be expected.
To put into perspective how rare these late season snows are, 1" or more of measurable snow after April 26th has only occured nine times in recorded history. The last time being April 29th, 2014 when 1.2" fell.
