Will the thermal wind kick in at Walchensee today?
LI -3.2 β thunderstorm risk destroys the thermal
How the day was forecast at the time, before the rules were recalibrated β shown for comparison only.
| Rule | Signal | Reason |
|---|---|---|
| Pressure gradient (Munich β Innsbruck)? | no_go | Ξ=-2.0 hPa β pressure gradient pushing against the thermal |
| FΓΆhn (Bolzano β Innsbruck)? | go | no FΓΆhn pressure signature (Ξ=-1.3 hPa) |
| Overnight cooling? | go | clear night: 53% cloud cover |
| Solar radiation? | go | peak solar radiation 816 W/mΒ² β₯ threshold |
| Dew-point spread? | maybe | dew-point spread 6.5Β°C β marginal |
| Boundary-layer height? | go | boundary layer 2615 m β deep mixing |
| Ground moisture / rain? | go | dry ground (soil moisture 0.22 mΒ³/mΒ³) |
| Atmospheric stability? | no_go | LI -3.2 β thunderstorm risk destroys the thermal |
| Daytime cloud cover? | go | 13% low cloud β slopes in full sun |
| Upper-level wind (850 / 700 hPa)? | go | upper wind from 257Β° @ 700 hPa 17 kt β neutral |
| Synoptic-flow override? | go | no overwhelming synoptic flow |
