September RecapAs the 4th hottest summer (June-August) on record ended, September provided little relief overall with well above average heat continuing. Overall very warm conditions lasted until the last few days of the month with highs in the 90's on 20 of the first 25 days of the month. In addition, September was a very dry month with most locations in the metro receiving less than an inch of rain. The last two weeks of the month saw "abnormally dry" conditions officially give way to "moderate drought" for portions of the metro, including southern Shelby County into north MS. There was no severe weather during the month.
|The Drought Index for the Mid-South at the beginning of October shows moderate drought (D1) over the southern metro and abnormally dry (D0) conditions for the rest of the metro.|
