my job disappears without trace - parallel-processing

Question

I am running a weather forecast model and I want to automate the modek runs via crontab. When I submit my job interactive through:
qsub -I -l nodes=8:ppn=8 -l walltime=2:00:00
The job runs ok.
When I submit through crontab, the job disappears without any trace, no error file any where, no output file, except mail which reads as:
From: root#master.cluster (Cron Daemon)
To: test#master.cluster
Subject: Cron <test#master> PATH=/opt/torque/bin:/usr/bin:/bin:. qsub /home/test
/WRF/SCRIPTS/wrf_00_run.sh

Here is my crontab entry
50 09 * * * PATH=/opt/torque/bin:/usr/bin:/bin:. qsub /home/test/WRF/SCRIPTS/wrf_submit_00.sh
and wrf_submit_00.sh has two dependent jobs to run consecutively
#!/bin/bash
cd WRF/WRFV3/run
FIRST =`qsub wrf_initialise.sh`
echo $FIRST
SECOND = `qsub -w depend=afterok:$FIRST wrf_00_run.sh`
echo $SECOND
exit 0
and the first job is
#!/bin/bash
#PBS -l nodes=8:ppn=8
cd WRF/WRFV3/run
echo -n "this script is running on: "
hostname -f
date
echo ""
echo "### PBS_NODEFILE (${PBS_NODEFILE}) ###"
cat ${PBS_NODEFILE}
echo ""
mpirun ./real.exe
exit 0
When I submit the two jobs separately through crontab I get the same disappearance.
Please help!, am stuck. Google search of a similar problem gives me no clue.
