BATON ROUGE, La. (WAFB) - Deep tropical moisture is forecast to remain over top of the Baton Rouge metro area through at least Saturday. This will cause a continuation of the nuisance-type flood threat for the area through at least Saturday.

Jeff Morrow and the WAFB First Alert weather team give an update on What We're Tracking Next on Wednesday, July 20.

The Weather Prediction Center has placed the area under a Marginal Risk (1 out of 4) for excessive rainfall now through Saturday. Rain chances are listed in the likely category Thursday through Saturday, but chances will begin to decrease into the weekend.

Pockets of heavy rain could lead to very small 2-4″ bullseyes in the coming days. Any flash flooding would likely be of the nuisance variety (i.e. roads, streams, bayous, and ditches). Low-lying, poorly drained areas are most at risk. The Weather Prediction Center has outlined 1-2″ of additional rainfall on average through the next three days. These totals would be manageable for most if it is spread out over the three-day period.

High pressure will expand from the west as we move into next week. This won’t completely cut off rain chances but we should transition to a mainly dry pattern albeit briefly. Rain chances will be 30-40% Sunday through Wednesday of next week. This will give most a chance to dry off and maybe do some much-needed yard work.

Unfortunately, the break from the rain doesn’t look to last long as long-range models indicate the potential for another stretch of wet weather days as we end next week.
