Kathy,
This mornings KFSD state forecast was in the 99022610.stfcst file
and is not being retrieved by nwx.

The reason that nwx can't find the report is that St. Louis (KLSX) has
a "null" character in their report which makes nwx stop reading-
and therefore cannot find any station further down in the file.

Here is a quick fix...
cd $TEXT_DATA/pubprod/stfcst
mv 99022610.stfcst 99022610.stfcst.bak
cat 99022610.stfcst.bak | tr -d '\000' > ! 99022610.stfcst

The above command will delete all "null" characters from the file.

A longterm fix will be to make nwx more forgiving of imbedded
null characters and other garbage in the data stream.
