Snowpack 24-Hours Later

In a post yesterday, we noted the widespread, deep snowpack still in place over Northeast Oklahoma, Northwest Arkansas and adjacent portions of Kansas and Missouri.  Below is the latest snow depth analysis, 24 hours later, from the National Snow Analysis Center:

As you can see, significant melting took place over the last 24 hours, as temperatures stayed above freezing for the longest period in nearly 10 days.  High temperatures on Saturday reached the 50s across most of the snowpack:  

At the official NWS observation site for Tulsa (at the airport), the temperature only briefly went back down to freezing early this morning before rising back up again shortly thereafter.

This, coupled with expected high temperatures in the upper 50s to lower 60s across much of the region will spell more widespread snow melt today.

The melting snow is also serving to moisten the ground quite well.  Here is the latest estimate of the water equivalent of the snow that is left on the ground across the region this morning:
