Updated 5/10/17

I'll keep this short. In the previous post on Saturday the 6th (you can read it by clicking here) I discussed the storm that is currently upon us.  It's evolution has been almost identical to the ice storm that impacted the high plains on or around the 15th of January.  But, obviously this is May and that January system was during the dead of winter.  The upper level is identical (how it developed, how it has moved, and how it WILL move and weaken) , the impacts will not be.  Here is the latest satellite image as of this Wednesday afternoon:

A close up shows how the air aloft is diffluent and diverging:


The impacts so far for the high plains have been several rounds of at least scattered thunderstorms.  More storms are expected into tonight and isolated to scattered showers as the storm departs and weakens on Thursday.  Here is the expected precipitation amounts, on average through Sunday:

Some will get more, some will get less.

Beyond this system, the atmosphere will become very spring-like.  Each day next week should have a risk of thunderstorms (and some will likely be severe).  This far out, it is impossible to pinpoint just where in the plains.  As we get to that point, I'll try and post an update.  Also next week I'll try and give an outlook going through the remainder of the spring and into the summer.  Stay tuned.
