MOS Comparison Tool

Following model trends is invaluable to producing a good forecast. Twister's MOS-Comparison tool allows you to quickly view how MOS products have changed since their last run.

Values are color-coded to help use this utility:

  • Orange numbers display the decrease in value since the last run
  • Green numbers display the increase in value since the last run.
  • Gray numbers (always 0) indicate that the value has not changed.

Enter a 4 letter station identifier (e.g. KCMH) below to use this tool. Use our station lookup tool if you need help finding a station.
