September 2016 - Report and Summary

The month of September 2016 was warmer and drier than normal. The thirty-day outlook had called for near normal temperatures and below normal precipitation. When revised on August 31, it called for above normal temperatures and below normal precipitation. Compared with September 2015, the month was 0.5 deg. Cooler, and 1.18 inches wetter. Year-to-date rainfall through September 30 was 11.28 inches less in 2016 than in 2015. Upper air high pressure dominated the area's weather for the first two weeks of the month. This resulted in very little rainfall, and temperatures which ran slightly above normal. There were a few showers with weak cold fronts on the 3rd and 10th, which also lowered temperatures back to near normal values.

Between the 14th and 18th, the area was sandwiched between a tropical low over the Gulf and low pressure over the Plains. This resulted in showers daily during the period, with coverage most extensive (never more than 40 percent) on the 15th and 17th. Upper air high pressure returned on the 19th, again warming temperatures. Drier air arrived on the night of the 20th, which lowered minimum readings for a couple of days. Gulf Moisture along with upper air high pressure returned on the 22nd, keeping temperatures warm and permitting a few showers on the 23rd and 24th.

A significant pattern change came on the 25th when a cold front and upper air low arrived. This brought numerous showers, and lowered temperatures to near normal levels through the end of the month.

The reporting period for temperatures and phenomenon on each day is for the twenty-four hours ending at midnight hours GMT--6 p.m. CST and 7 p.m. CDT. The reporting period for precipitation is for the twenty-four hours ending at noon GMT--6 a.m. CST and 7 a.m. CDT.
