There is some good information at on the Agweather site that can certainly benefit grape growers.  Follow this link to see what I mean:

Look on the left to see the “Grape” tab.  Click on that and a drop-down menu comes up.  Links under Irrigation, Pest Control, Marketing, and Professional Resources all provide excellent information for any grower.  One thing I found out is that Stillwater is forecast to hit a low of 35 F on Sunday night.  Enough to make me get a little nervous.
