[GEMPAK #UJV-485868]: snlist/sndslist data ordering

Hi Kelton,

I see this with some stations, it doesn't look good to output out of order like 
that, but from looking at snlist source code I don't see any easy fix.  
However, I did notice that the mandatory pressure levels being reported showed 
-9999 (missing) TMPF:

 SNPARM = PRES;TMPF                                                             

 STID = DNR           STNM =    72469    TIME = 140617/1200         
 SLAT =  39.77     SLON =  -104.87   SELV =  1625.0
 STIM =  1200


      PRES     TMPF
    832.00    52.52
   1000.00 -9999.00
    925.00 -9999.00
    850.00 -9999.00
    831.00    53.60
    830.00    55.40

I changed to "SNPARM = tmpf>-9999" and now:

      PRES     TMPF
    832.00    52.52
    831.00    53.60
    830.00    55.40
    827.00    61.52
    820.00    65.48

Hopefully this helps...

-Michael
