Episode narrativeepisode_narrative	A broad cutoff upper low, which had been located over central Texas, was beginning to move very slowly east by the 16th. This upper low, in combination with unusually deep tropical moisture across the region for mid-September, began an extensive period of showers and thunderstorms with very heavy rain. The deep tropical moisture was largely the result of a persistent 850 mb flow from the Gulf of Mexico. The pattern changed very little for nearly a week as the upper low drifted very slowly east, completely cutoff from the main belt of westerlies, which were located well to the north in southern Canada. The first flash flood event of an extended period of historical and record flooding across north and central Georgia, began on the 15th in Gilmer county. A few storms became strong to marginally severe as well.\|\|A historical, record, and catastrophic flood event began to unfolded during this period, mostly in the west central Georgia area, including the western and northwestern suburbs of Atlanta. Major flooding was noted in many other areas of north and central Georgia, including the eastern suburbs of Atlanta, northwest Georgia, and parts of central Georgia. The culprit was a very stagnant upper atmospheric pattern featuring a weak upper low that developed in early September across south Texas and slowly migrated east-northeast through September 22nd, until a more significant upper trough dropping south into the southern plains finally moved the pesky upper low northeast of Georgia. In addition, an unusually deep tropical flow was noted throughout this period. Precipitable water values exceeded 2.0 inches across the area during this time, resulting in extremely efficient rain producing cells. Persistent heavy rain showers and thunderstorms began to plague the area on the 16th, and persisted daily across parts of north and central Georgia.
