Meeting Minutes
The most recent meeting of the Central Illinois Chapter was held 15
May 2002 at The Depot restaurant in Lincoln, Illinois. After dinner, a
brief business meeting was conducted. President Holicky polled group opinion
on hosting a regional AMS conference. There was interest and a decision
whether or not to pursue hosting the conference is expected to be reached
at the next meeting. The evening's speaker was Brad Ketcham, forecaster
at the Central Illinois National Weather Service Forecast Office. His topic
was "The Interactive Forecast Preparation System (IFPS): A Digital Forecasting
Process." IFPS is a new component of the Advanced Weather Interactive Processing
System (AWIPS). It allows the forecaster to view and edit gridded fields
of weather information. It also allows the forecaster to blend and manually
modify model forecasts. Users may generate these fields with any combination
of model forecasts, other guidance products, observations, or premade user-generated
gridded forecasts. IFPS gives users the ability to generate products from
the digital database into various formats such as tabular, text, graphical
imagery and gridded files. With IFPS, the forecaster can present the forecast
products in a number of ways to suit the public's requirements and desires.
Initial nationwide implementation of IFPS is underway but development will
continue for some time. It promises to be an exciting addition to the NWS
forecast process that should take the weather agency into the 21st century.---Scott
Kampas.
The second meeting of the year for the Central Illinois Chapter was
held 7 March 2002 at Marcia's Waterfront Restaurant in Decatur, Illinois.
The evening's speaker was delayed due to air travel difficulties. Dinner
was begun slightly late, followed by a brief business meeting. The secretary
and treasurer's reports were read, and then Vice President Ed Kieser talked
briefly on some chapter news. President Ed Holicky had to leave promptly
due to a family emergency, so other announcements were pushed back to the
next meeting. Finally, the evening's program commenced. Roger Edwards of
the Storm Prediction Center presented "Forecasting and Observing the May
3, 1999 Central Oklahoma Tornadoes." This day was among the most prolific
severe weather days ever. The current count is over seventy tornadoes,
with nearly fifty fatalities and over $1 billion in damage. This event
was poorly forecasted by the numerical models; and even the morning of
the event forecasters at the Storm Prediction Center did not realize the
threat. The "saving grace" for the dayís forecast was that the upper
air environment was sampled well enough for forecasters to realize conditions
were setting up for a major event. Combining the tremendous shear in phase
with the high instabilities, and the atmosphere was primed for an epic
severe weather event. Storm initiation time and place remained uncertain
until mid-afternoon. It is thought that a break in a cloud field, in conjunction
with a horizontal roll triggered storm initiation. An area of confluence
and the predominance of warm, moist downdrafts are among the factors under
study as contributing to the severity of the tornado outbreak.---Scott
Kampas.
The Central Illinois Chapter held its final meeting of the 2001 calendar
year on 6 December. The meeting, a joint meeting with the Indiana Chapter,

University in Indianapolis. His program was ìThe Development of
a New Wind Chill Temperature Chart.
The chapter held its first meeting of the year on 4 February 2002. The
meeting was held at Marciaís Waterfront Restaurant in Decatur, Illinois.
Brief secretary and treasurer reports were read. Dave Kristovich followed
