Downpours of rains in mid-August have broken a stretch of mostly dry conditions during the first half of August 2019, in radical contrast to the wetness of June-July.

Temperatures_Summer 2019

Abundant summer rainfall and clouds have kept air temperatures significantly cooler in the high country of the High Knob Massif, with latent heat fluxes related to the evapotranspiration of water ruling the surface energy budget.  A review of mesonet data from the University Of Virginia's College At Wise Undergraduate Research Program illustrates this very well.

This is a Saddleback Caterpillar (Acharia stimulea), with stimulea being a very appropriate species name as you will certainly be stimulated if touching this little fellow.
