We were in the grips of the main part of the 2012 heatwave at this time last year. The hottest day, overall, in the viewing area was July 6.
Below are our WLFI weather stations & weather stations set up at spotters’ homes.

In extreme heat events with light winds, soil moisture often dictates how high temperatures get in an overall very hot regime. The drier the soils, the hotter the temperature. The wetter soils show up very well in these high temperature graphics with upper 90s where more rain had been falling. However, in areas that could not buy a drop of rain, specificially areas with sensors over sandy loam or sandy soils common in parts of the area, temperatures were exceptionally high.
