Ξ=-2.0 hPa β pressure gradient pushing against 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? | no_go | 99% overnight cloud cover β weak inversion |
| Solar radiation? | no_go | peak solar radiation 505 W/mΒ² below 600 |
| Dew-point spread? | maybe | dew-point spread 3.0Β°C β marginal |
| Boundary-layer height? | go | boundary layer 1515 m β deep mixing |
| Ground moisture / rain? | no_go | 15.6 mm rain yesterday β solar energy lost to evaporation |
| Atmospheric stability? | go | LI 0.6β¦2.8 β stability in normal range |
| Daytime cloud cover? | no_go | 87% low cloud during the day β slopes shaded |
| Upper-level wind (850 / 700 hPa)? | go | upper wind from 281Β° @ 700 hPa 22 kt β neutral |
| Synoptic-flow override? | go | no overwhelming synoptic flow |
| Thermal ignition (live)? | go | ignited at Mittenwald/Obb. |
