August 2015 was very wet in some areas but near normal in temperature

Precipitation across Georgia in August 2015 varied from over ten inches near the coast and in north central Georgia to less than 2 inc hes in the southwest corner of the state.  A few isolated areas received over 15 inches during the month, according to CoCoRaHS observers.  Temperatures were very close to normal across the state. The coolest areas were generally also the wettest.

Coastal areas of Georgia as well as areas to the east of Atlanta were the wettest parts of the state.  The driest area was in the southwest near Thomasville.

Three daily rainfall records were set in August.  Columbus received 3.80 inches on August 6, breaking the old record of 1.65 inches set in 1966.  Brunswick received 4.07 inches on August 31, breaking the old record of 1.36 inches set in 1991 and Alma received 4.65 inches on August 28, breaking the old record of 1.64 inches set in 1954.

The highest single-day rainfall from CoCoRaHS stations was 5.22 inches west of Valdosta in Lowndes County on August 31, followed by 5.04 inches received west of Bethlehem in Gwinnett County on August 23. The highest monthly total rainfall was 18.55 inches, observed east of Savannah in Chatham County.  Another nearby observer reported 16.06 inches in August.

Severe weather was observed on 15 out of 31 days during the month.  Almost all of them were due to scattered wind damage.  A microburst caused significant tree damage to the Rock Eagle 4-H facility near Eatonton on August 6 along with widespread wind damage in other parts of the state on that day.

Crops generally did well in August across the state, although dry conditions caused some stress and increased pest pressure.

The Drought Monitor shows that drought increased across the state again in August.  Drought conditions across large parts of the state are expected to increase for the next three months.  However, if El Nino conditions come early this winter, wet conditions could reduce dryness drastically.  This could occur early this year due to the strength of the El Nino, so farmers should harvest in a timely manner, especially on fields that are prone to flooding.  Temperatures in September are expected to be above normal across the state and may aid in maturing crops.  The expected dry conditions could hamper efforts to plant wheat, cool season vegetables, and fescue.
