Potential Wx Concerns
D. JuddWestwide Avalanche Network
• Forecasts of Precipitation in the Mountains• Forecasts for tiny sports venues at precise
fixed times• Heavy Snow• Strong Winds• Too Warm for Snowmaking• Rain on Snow• Low Visibility: Fog or Snow• Lightning• Avalanches
• Air Pollution
![Page 13: Weather Support for 2002 Olympic Games Dr. Tom Potter SLOC Weather Coordinator and U. of Utah Meteo Dep’t](https://reader035.vdocuments.net/reader035/viewer/2022062320/56649d565503460f94a34428/html5/thumbnails/13.jpg)
Actual Weather
• Nearly Perfect for Winter Games : Colder & Drier than Normal, with no big
snowstorms, strong wind gusts, or low visibilities
• Few Weather Delays/Postponements - Mostly from Winds - Only one postponement from snow - Potential Wind/Lightning effects at all 4
Opening/Closing Ceremonies
![Page 14: Weather Support for 2002 Olympic Games Dr. Tom Potter SLOC Weather Coordinator and U. of Utah Meteo Dep’t](https://reader035.vdocuments.net/reader035/viewer/2022062320/56649d565503460f94a34428/html5/thumbnails/14.jpg)
Forecast Results
• Overall, forecasts were excellent, according to customers.
• Superb data sets and wide range of models available to experienced forecasters who coordinated well.
• Had high resolution analyses/forecasts.• MM5/MOS forecasts for venues were quite
accurate.• Detailed,precise forecasts for
Opening/Closing Ceremonies were exceptionally good.

Ongoing scientific issues
• QPF!!!– When, where, how much
• Highway surface modeling/guidance
• Snow-surface temperature/structure
• AQ during cold pools/inversions
