An upper-level disturbance in the jet stream combined with a moist atmosphere to produce widespread rain and thunderstorms Tuesday and Wednesday. Locally heavy rainfall fell at several points around central Louisiana.
According to high-resolution Doppler radar, the heaviest rain fell across portions of Winn, Grant, Natchitoches, and western Rapides Parishes. This trend verified well with the extensive rain gauge network of the National Weather Service and KALB-TV. Here are the top two-day totals:
Otis/Hineston...5.00 inches; Winnfield...3.65 inches; Aloha...3.40 inches; Oak Hill...3.21 inches; and Montgomery with 3.00 inches.
For the remainder of the week, the disturbance will lift out of the area and a seasonally strong ridge of high pressure aloft will rebuild. This will increase temperatures and lower rain chances.
