Southern Plains Drought Early Warning System

Conditions for the week of September 13–19

Short-term dryness brought modest expansion of dryness (D0) and moderate to severe drought (D1 to D2) to various areas.  Topsoil moisture rated very short to short increased at least 10 percentage points each of the last 2 weeks to reach 57% by September 17 in Texas, and 47% in Oklahoma, according to the U.S. Department of Agriculture.  Winter wheat planting is underway in the region, and the crop will soon need rain to support proper autumn establishment.  In Texas, 14% of the intended winter wheat acreage had been planted by September 17; Oklahoma had planted 11%. While deteriorating conditions affected parts of Kansas and environs.  In fact, some additional severe drought (D2) was introduced in Kansas, where topsoil moisture rated very short to short (by the U.S. Department of Agriculture) jumped from 38 to 58% during the 2 weeks ending September 17.
