<div class="eI2">Geopotential height (tens of m) at 925 hPa (solid line) and Temperature (&deg;C) at 925 hPa (coloured, dashed line) </div>
This chart helps to identify areas of densely packed isotherms (lines of equal temperature) 
indicating a front. Aside from this you can use the modeled temperature in 925 hPa (2000 ft a.s.l.)
to make a rough estimate on the expected maximum temperature in 2m above the ground.
However, this method does not apply to (winter) inversions.
