Discussion. June 26... Weather synopsis along the X-Pyr course...
This summary table combines common forecast elements into a single quick review for a day's soaring potential.

Vertical velocities
This table shows vertical velocity profiles across daylight hours for the selected day. Only the boundary layer levels are shown. The vertical velocities depicted here are strictly convective and do not include the contribution of ridge lift, gravity or mountain waves, or general upslope flows. The presence of these other mechanisms for soaring must be deduced by the general meteorlogical conditions. When sufficient triggers are present, these are the expected vertical velocity profiles and their respective top of usable lift.

Subtracting a glider's sink rate from the thermal updraft velocities gives the usable, realized velocity.

When cumulus cloud can form by lifting the parcel, the lifted condensation level (LCL) moment is depicted with a cloud icon. The effective top of usable lift will therefore be at the LCL.
This table depicts the surface temperatures around the selected location for select elevations throughout the day. For , an area within a radius of 10 km shows the minimum elevation is and the maximum elevation is .
Surface temperatures (2m)
This table is NOT a representation of the air temperature aloft, rather, it attempts to provide context for the expected air temperature at different surface elevations. In mountainous regions, a single temperature value does not tell the entire story of what to expect on ridge tops, etc.
Winds aloft
This table shows winds aloft through much of the lower atmosphere.
Mean sea level pressure
This table shows the mean sea level pressure trend across the day. These pressures are not adjusted using the typical method of the averaged 12 hours of temperature.
Relative humidity aloft
This table show the relative humidity profiles across the day by hour. Areas where RH values exceed 95% often indicate the presence of cloud. Moderate moisture in the lower boundary layer capped with dry air above is often what we soaring pilots look for. When conditions are relatively unstable and high levels of moisture exist through and above the boundary layer, large scale convection can occur, often resuling in thunderstorms and large cumulus cloud development.

The forecasts along a route show the general lift potential with other useful weather elements. Lift profiles can appear misleading at times if taken at face value. For example, the origin of thermals are often not directly underneath the realized tops due to upslope flows and winds aloft in general. In mountainous terrain, such as the Alps, this is particularly prevelant. The forecasts along a route are intended to provide guidance and trend information about the day's soaring potential. Winds are depicted on every route plot as wind barbs. Barbs are extremely helpful symbols to convey both wind direction and speed without the need for number labels.

Welcome to the X-Pyr weather and soaring forecast application. XC Skies and X-Pyr have teamed up to provide real-time weather and forecasts along the race course. Use this application to review forecasts and conditions at turnpoints and athlete locations.

Click a turnpoint, route segment or anywhere on the map to review detailed weather and soaring conditions for today and the next upcoming days. The forecast data used in this application is updated 4 times a day at roughly 04, 10, 16, and 22 UTC.

Athlete positions will update every few minutes when selected, courtesy of Flymaster LiveTrack.

Having trouble viewing this application on the X-Pyr website? Click here to open the app in a new window.

All times are shown in local Central European Summer Time (CEST). The selected forecast times are highlighted in yellow.

This application uses forecast data from the ICON European nested model, run by DWD. XC Skies then initializes parameterization and downscaling techniques to arrive at detailed forecasts for every 1km within the domain. Other forecsat models are available as xcskies.com, including Arome 2.5 km and the ICON 2.2 km, among many others.
