Notice of Flaw in GFS-LAMP Thunderstorm Forecasts
THURSDAY JULY 27, 2006
Attention LAMP users:
The GFS-based LAMP thunderstorm probability and categorical forecasts,
which became official in the NWS on 25 July 2006, presently contain a
noticeable problem. The problem consists of choppiness/roughness in the
forecast patterns and a slight degradation in accuracy. A fix for
the problem is presently scheduled for implementation on or about August 1st.
Thank you for your interest in LAMP.
Dr. Jerome Charba and Jerry Wiedenfeld
