OK.  Now, I am confused.  Here is what Gerry said:

---------------------------

I can't do it before Monday (real bad connectivity 'til I get to  
Boulder) but I'll make shapefiles available for download from  
mesonet.tamu.edu for warnings, updated every 15 minutes (for mow, may  
make them more frequent depending on load).  Should have done that a  
long time ago.

I'll post the page.  These will be shapefiles, with names consistent  
with the type of short-term warning.  If I'm real good, I can also  
create a counties-outline shapefile, although we are now all  
officially doing storm-based (polygon) files.

I also believe that NWS now makes these available.  google for 'NWS  
warning gis' and see if that doesn't help.  Like this: http:// 
www.weather.gov/regsci/gis/shapefiles/

As you can see in the first paragraph, I assumed from the 15 minute  
update interval, that the get_NWSdata script would have to be run,  
too.  I have not looked at the shape files, but perhaps they know  
when to get updates, and have the URL built-in to accomplish this.   
If we're talking about county weather alert data, they need to be  
updated often during the bad weather, right?

Maybe it's just a misunderstanding on my part as to how the NWS  
warning data updates xastir maps.  Please clear up my befuddled  
thinking. . . . .

Good, just confirmation on what I thought about my install.  Thanks.
