In contrast to my grumpy review a year ago this versions seems to work very well
and is very pretty
the radar map downloaded instantly and changing location procedure is now effortless
however
unless one needs the 7 day history or one of the neat automated features such as
"sound an alarm, send e-mails or SMS text messages, or run an AppleScript when severe weather alerts are issued by the NWS"

all the basic information is available for free (as the author notes) at

http://radar.weather.gov/radar.php?rid=cbx&product=N0R&loop=yes
and
http://www.wrh.noaa.gov/forecast/MapClick.php?site=BOI&llon=-116.606247&rlon=-114.923747&tlat=44.002084&blat=42.322084&smap=1&mp=0&map.x=61&map.y=59

The urls above are specific to Boise but easily be changed
Suggest the author add a link to "http://radar.weather.gov/Conus/full_loop.php" where one gets a nice live weather map of the entire country

from the entire country map a click on your location brings up the local radar and a link to the forecast page
