Super Strong Spring Storm

Well this storm is incredibly tricky to forecast with temperatures fluctuating between above and below freezing. Right now it looks like there will be two strong waves of snow, the first being in the NW section of the state, this will occur tonight and into Monday. When temps rise up above freezing we'll see a mix of rain and snow and sleet, making conditions super sloppy. You can see there is a gap between 12+" snow accumulation - that's the area that could see 12+ inches of snow, but most likely won't as the system will be producing more of a rain/snow mix so they won't see just snow thus not as much accumulation. The more snow on the Eastern half of the state will come from the intensification of the low pressure system. It will be a product of long lasting wrap around snow Monday night through Tuesday evening.

So right now we are in the region where the black arrow are... this is ahead of the low, also the reason we are seeing some rain right now due to the southerly winds bringing up the moisture. That moisture wraps around the low pressure because winds circle counter-clockwise around a low. When the moisture catches up to cooler air being brought down from the north, that's when we get "wrap around snow". And since this system will intensify as it slowly moves over our region, we're going to see a whole lot of it in Eastern SD, producing snow totals close to what you saw earlier.

Cody and Aaron will keep you posted as this storm progresses - hope you didn't put away your snow boots!
