Forests that historically had large areas with no snow on the ground for two to four months and high moisture loss from soils and vegetation in spring and summer have seen the biggest increases in wildfire in early spring snowmelt years (for example, the northern Rockies and parts of the Sierra Nevada).
Six Chinese scientists used remotely - sensed imaging data, including leaf area index (LAI), normalized difference vegetation index (NDVI), an enhanced vegetation index (EVI), gross primary production (GPP) and net primary production (NPP), coupled with other data (temperature, soil moisture, evapotranspiration, albedo and wind) over the period 2003 to 2014 to analyze the effects of a wind farm on summer vegetative growth in a region of northern China.
Even in areas where precipitation does not decrease, these increases in surface evaporation and loss of water from plants lead to more rapid drying of soils if the effects of higher temperatures are not offset by other changes (such as reduced wind speed or increased humidity).5 As soil dries out, a larger proportion of the incoming heat from the sun goes into heating the soil and adjacent air rather than evaporating its moisture, resulting in hotter summers under drier climatic conditions.6

Dependence of extreme daily maximum temperatures on antecedent soil moisture in the contiguous United States during summer
[Response: Your argument misses the point in three different and important ways, not even considering whether or not the Black Hills data have any general applicability elsewhere, which they may or may not: (1) It ignores the point made in the post about the potential effect of previous, seasonal warming on the magnitude of an extreme event in mid summer to early fall, due to things like (especially) a depletion in soil moisture and consequent accumulation of degree days, (2) it ignores that biological sensitivity is far FAR greater during the warm season than the cold season for a whole number of crucial variables ranging from respiration and photosynthesis to transpiration rates, and (3) it ignores the potential for derivative effects, particularly fire and smoke, in radically increasing the local temperature effects of the heat wave.
Planting a bit early, if the fields are dry enough to support farm machinery, can improve results — but that outcome depends on having enough soil moisture, and having no peak temperature during the summer high enough to stop seed from forming.
Rising summer temperatures are reducing soil moisture, he pointed out, leading to increased irrigation demands that threaten to strain water resources.
Now, however, researchers from China, France and Switzerland have found that including information about precipitation frequency may also significantly improve our ability to explain variations of moisture in summer soil.
