WSI Introduces MarketFirst(TM)

WSI Corporation, the world's leading provider of weather-driven
business solutions, today announced WSI MarketFirst(TM), a
proprietary, patent-pending technique to predict the forecast of
future weather model runs, including the Global Forecasting System
(GFS) model issued by NOAA. The product is unique in that it is a
"forecast of a forecast", rather than a forecast of the weather.

Because weather drives the natural gas, electricity, and
hydro-electric energy markets, WSI MarketFirst is issued one hour
before the GFS Operational run, providing early, valuable information
to energy traders. WSI MarketFirst predicts future model runs
correctly 70 to 80 percent of the time.

"Energy traders are looking for unique, innovative products that
give them an edge in the market," said Ira Scharf, WSI's Vice
President of Energy Services. "This kind of information has been on
energy traders' wish lists for a long time and WSI has met the
difficult challenge and delivered it. WSI MarketFirst is truly a
breakthrough product that no one else in the industry can offer."

About WSI MarketFirst

WSI MarketFirst predicts changes in the 12Z GFS Operational run,
relative to the 00Z GFS Operational run, and is available one hour
before the 12Z GFS is released. Available in the US and in Europe, the
product is comprised of individual forecasts for each day, from day 6
to day 15, as well as two aggregate forecasts, one each for the 6-10
and 11-15 day periods. Since the 12Z GFS model is one of the primary
market movers, WSI MarketFirst gives customers potentially lucrative
advantages in the market.

The aggregate skill of the technique, expressed in terms of
directional correctness, is 70 percent. However, for the 40 percent of
WSI's forecasts in which its confidence is highest, skill increases to
80 percent.
