Update 10/13/15

In the post I did on the 5th (click here) I discussed an upper low that was spinning across California and moving towards New Mexico.  As expected the low became cut off from the flow and never made it past Albuquerque.   As a result, the rainfall across much of Kansas was limited although a few locations got over an inch!  The bulk of the rainfall, as expected, was across New Mexico and west Texas.  Here is the map of the 7 day rainfall ending yesterday.


In a typical pattern the low would have moved out into the plains and would have brought copious moisture to many areas.  But in this case, the low drifted south and then west.  What is somewhat amazing is that this low is still alive and well!  As of Tuesday afternoon the low was southwest of San Diego and drifting north.  Here is the satellite image....(click for a larger map)


There is a small chance that the jet stream across the Pacific could move this low towards the plains by the end of the weekend.  The only problem is that it would likely undergo a degeneration process as it does.  The result would be only a small chance for precipitation.  But even if it does decay, the trough across the Pacific (the dip in the jet stream or green line) will be approaching and this may be enough to bring some showers and storms to the center of the country.

The Weather Prediction Center offers the following precipitation possibility through next Monday....

That is not a lot of moisture for the wheat belt, unfortunately.  Looking slightly ahead to the balance of the month, there is only a small indication of decent moisture towards Halloween.  I'm leaning on the pessimistic side right now.  I'll try and update at the end of the week and see if anything starts showing up.  As far as a freeze, there is nothing significant in the near term although scattered frost could certainly occur later this weekend.
