📊 Chart Parameters

MSLP & 3h Precipitation
Mean Sea Level Pressure contours overlaid with 3-hourly precipitation shading. Shows where weather systems are located and where rain or snow is falling.
Thickness & Precipitation
Atmospheric thickness contours overlaid with precipitation. Blue contours indicate cold air masses; red/purple contours indicate warm air. A useful guide to whether precipitation is falling as rain or snow.
850 hPa Temperature
Temperature at approximately 1,500 metres above sea level. A good indicator of the overall warmth or coldness of an air mass affecting a region.
500 hPa Temperature
Temperature at approximately 5,500 metres above sea level. Cold air at this level is associated with instability, thunderstorms and heavy precipitation.
700 hPa Relative Humidity
Humidity at approximately 3,000 metres above sea level. High values indicate moist air and cloud at mid-levels, often associated with significant rainfall or snowfall.
Accumulated Precipitation
Total rainfall and snowfall accumulation from the start of the model run. Useful for identifying regions receiving persistent or heavy precipitation over the forecast period.
Snow Level
The altitude (metres above sea level) where precipitation is falling as snow. Lower values mean snow is reaching lower elevations. Only shown where precipitation is occurring.
