Freeze Depth

With all the wind events this winter, the snow has been moved and shifted several times.  Many of you may be aware that the North Dakota Agricultural Weather Network has soil temperatures probes situated around the region.  In turn, you can get an idea of the freeze depth.  Because of this shifting of snow, there are many bare areas where the frost depth goes down to five feet and probably deeper.  Yet under the drifts the frost depth is two feet or less in other areas.  This spot to spot variation is very common for us which always makes it difficult to determine has quickly that frost will end up melting once spring finally arrives.
