Set this line to false to get rid of the NWS records.
$useWU = true; // set to false if you do not want to use "new record High/low" image
To removed the storm rain find and delete the following.
<tr>
<td class="data1" nowrap="nowrap">Storm Rain: </td>
<td style="text-align: right;" class="data1">
<?php echo strip_units($vpstormrain).$uomRain; ?>
</td>
</tr>
The fire risk looks like you don't have the images or you have the directory set wrong.
