Significant rainfall is forecast over south Louisiana beginning Thursday afternoon and lasting through Saturday. A total of 1-3 inches of rain could fall, with some areas seeing upwards of 3.5 inches.

As a rainmaker exits Texas, showers and thunderstorms will begin to increase in coverage over Louisiana Thursday afternoon. Chances of rain remain scattered through Friday morning, around 30 percent coverage. However, rain overtakes the area, around 80 percent coverage, by mid-morning Friday.

The Stormtracker33 Futurecast model predicts Baton Rouge will measure over 1.5 inches of rain within the next 48-hours. Further south, Donaldsonville and Morgan City, Louisiana could measure over 2 inches.


Several weeks have passed since south Louisiana's last measureable showers and thunderstorms fell; the most recent being April 14, 2014.

As a whole, the April 2014 was dry one. Only 4 days of the month brought rain totals over a tenth of an inch in Baton Rouge. The highest rain measured, and closest amount to the next 48-hour forecast, fell over a month ago on April 6, 2014. As mentioned earlier, south Louisiana is forecast to measure from 1-3 inches from Thursday afternoon through Saturday.

(Side note: April 18, 22, 27, 28, 29 and May 1 only measured  0.02 inches or less, making them less than significant events.)

Other than a few heavy downpours embedded within the thunderstorms on Friday. No widespread, severe weather is forecast heading into the weekend.
