South: Another round of moderate to heavy rainfall — partly associated with remnants of Hurricane Sergio in the eastern Pacific — was responsible for additional widespread reductions of drought intensity and coverage. Much of central and eastern Texas was doused with 2 to 10 inches of rain, with amounts locally more than 12 inches from the Edwards Plateau to Lufkin. This rain fell on top of last week’s downpours, pushing 30-day totals to locally more than 20 inches. During the 7-day monitoring period, the axis of heavy rainfall (2-6 inches) extended east-northeastward across southeastern Oklahoma, Arkansas, northern Louisiana, into western Tennessee; widespread 1- and 2-category reductions were made to the drought analysis, and with more rain falling after the Tuesday-morning cutoff, additional reductions in the lingering Abnormal Dryness (D0) are likely.
Looking Ahead:Mostly dry conditions will prevail across the contiguous U.S., with the threat of additional heavy rain confined to Texas. Showers will accompany a strong cold front over the eastern third of the nation Friday into Saturday, but amounts will be generally light. This same front will bring sharply colder weather on gusty winds as well rain and high-elevation snow showers to the northeastern quarter of the nation. In contrast, high pressure will maintain mostly dry weather across the central and western U.S., save for lingering rain and snow showers over the Four Corners States.
The NWS 6- to 10-day outlook for Oct. 23 – 27 calls for near- to above-normal precipitation over much of the nation, with the greatest likelihood of wetter-than-normal conditions in the Pacific Northwest, southern Plains, and eastern Gulf Coast. Drier-than-normal weather will be limited to the Great Lakes and Northeast. Warmer-than-normal weather across the eastern half of the nation — save for warmth across the central and eastern Gulf Coast — will contrast with above-normal temperatures from the northern Plains to the Pacific Coast States.
