As of August 7th Western Clarke Co Iowa was (IA-CL-3) -1.74" below normal for the growing season year (October to September) Or -2.74” below normal for the calendar year. Currently checking multiple counties of Union, Clarke, Madison, Adair, Warren Counties all are seeing signs of drought /abnormally dry conditions. abnormally dry conditions and now noted via farmers and grassland area checks in the above noted counties cracking and farmer showing concern as 3rd cutting of grassland for cattle feed is look to NOT going to be possible. All grassland and crops growth has slowed considerably or has stopped altogether. Lakes, Ponds are all showing minor decreases in activities and levels. Rivers and creeks are below normal. CoCoRaHS for the area of southern Iowa are all showing decreases in amounts and increasing drought. The dry conditions are showing surface cracking of the ground, cracking is increasing dramatically in Western Clarke County Iowa cracks are up to 1 3/4” Wide and depth checks showed some at 20” deep before bottom was hit. These signs are noted ALL across Clarke County and noted in Union County Iowa also causing accelerating drought conditions. All of Clarke County and areas west are in D-1, corresponding areas of drought are also creeping northward. D-0 Abnormally Dry conditions are are now on the door step of the Des Moines Metro Iowa area, and I would expect a good 15-20 mile advancement to the North and West in Iowa. Signs of dryness reach Interstate 80 Corridor. Humidity is also reduced, and a slight Arid climate is starting to be noted in daily high temperatures and drop offs in low temperatures. Humidity is lower than normal for this time of year.
