 | Title : Standard Chill Unit
 | Date  : 10 Apr 10:40 PM
 | Author: Daryl Herzmann
 | URL   : http://mesonet.agron.iastate.edu/agclimate/display.php?prod=12
 +----------------------------------------------

I have updated the ISU AgClimate pages this evening and have 
included a new accumulation plot of Standard Chill Units.  This 
value is somewhat abstract to understand, but has relevant 
application for fruit growers in the state.  The link mentioned
in this news item contains more information on the plot.

I have also updated the daily plots to make them look much 
cleaner and fix long standing plotting bugs (display only).

If you have ideas for new plots, please let me know.

 | Title : Enough of the northwest flow
 | Date  : 10 Apr 07:20 AM
 | Votes : Good: 33   Bad: 5
 +----------------------------------------------

The featured image is a wind rose for the Des Moines Airport this month.  It is fairly obvious that northwest flow has dominated and is a big reason why temperatures have been below normal. The first in a series of storms will help break up this persistent flow pattern, but warmer temperatures will only be brief.  A considerable amount of snowfall is even expected in Northern Iowa with these next storms!
