NWS Lincoln taking part in 'mixed case experiment'

Send a link to a friend

[July 31, 2013]  Starting Wednesday at 1 p.m., the National Weather Service office in Lincoln will begin issuing a small set of its published products using mixed case characters.

What does that mean?

This means that for a few of the public announcements and many of the river and climate materials, both uppercase and lowercase letters will be used in the body of the message, as well as numerous special keyboard characters, instead of all capital letters and only a few punctuation marks.

Why do most NWS products use all capital letters?

For decades, the National Weather Service was limited to using only capital letters and a small set of punctuation marks because of the teletype machines and wire services that were used to disseminate and receive the text products, such as weather forecasts and warnings.

Some computer systems that receive the messages are still programmed to receive the NWS information in the ALL CAPS form. This experiment will allow users and partners to update, identify and correct any problems in their systems with the reception of messages containing an expanded character set, with uppercase, lowercase and special symbols).

What products will be part of this experiment?

Three public products and 11 hydrologic and climate products will be part of the experiment. The public products are:

  • AFD -- Area Forecast Discussion

  • PNS -- Public Information Statement

  • RWS -- Regional Weather Summary

The 11 hydrologic and climate products are:

  • ESF -- Hydrologic Outlook

  • FFA -- Flood Watch for Forecast Points

  • FLW -- Flood Warning for Forecast Points

  • FLS -- Follow-up to Flood Warning for FP

  • FLS -- Flood Advisory for Forecast Points

  • RVS -- Hydrologic Statement

  • RVA -- Hydrologic Summary

  • RVD -- River and Lake Forecast Product

  • HYx -- Hydrometeorological Data Summary
