Announcement of New Web Graphic for LAMP Probabilities and Thresholds

LAMP Announcement

February 10, 2009

TUESDAY FEBRUARY 10, 2009

LAMP Users,

On or about February 10, 2009 a new graphic will be available on the LAMP web page. The graphic shows LAMP probability forecasts and associated thresholds for the aviation elements of:

  • Ceiling height
  • Conditional ceiling height (conditional on precipitation occurring)
  • Visibility
  • Conditional visibility (conditional on precipitation occurring)
  • Probability of Precipitation on the Hour
  • Probability of Freezing
  • Probability of Freezing or Snow

This information is available for all LAMP stations, and all LAMP cycles. The precipitation type information is available on the "Uncertainty Plot" tab.

The intent of this web page is to allow users to easily see the probabilities for critical aviation categories and elements, and to see how they relate to their associated thresholds which together determine the best category selected in LAMP.

The web page is available from the main LAMP Products Page under "Probability Plots":
http://weather.gov/mdl/gfslamp/gfslamp.shtml

or directly from :

http://weather.gov/mdl/gfslamp/uncertform.php

Documentation explaining what is offered on the page can be found at:

http://weather.gov/mdl/gfslamp/docs/uncertplots_info.shtml

and a powerpoint presentation "tutorial" explaining this in more detail can be found at:

http://weather.gov/mdl/gfslamp/docs/uncert_help.ppt

We hope that you might find this information useful. Please let us know if you have any questions or comments.
