Here's a bash function I use to do something very similar.  It relies on 
the fact that when dates are in YYYYMMDD format, comparing the dates as 
integers has the same result as comparing them chronologically.  It does 
use some bash-specific variable substring enhancements to avoid running 
processes to get the remind output in YYYYMMDD format.

remind_after_today() {
   local today=$(date +%Y%m%d)

   while read date x x x x rest; do
     if [ "${date:0:4}${date:5:2}${date:8:2}" -ge "$today" ]; then
       echo "$date $rest";
     fi
   done
}

Place in the script that calls remind (or your .bashrc if you want to 
use it from the command line).  Use like "rem -s3 | remind_after_today".
