On Wednesday, weak low pressure of tropical origin moves slowly north from Louisiana into the Mid-South. As it does, moisture values increase to very high levels as lift provided by the approaching low and mid-level energy combine to produce showers and thunderstorms across the region. Though a few will be possible throughout the morning, chances increase to "likely" by lunchtime or just after in the metro. Severe weather is not expected as wind energy remains low and instability (the fuel for the fire) will be present, but not overly concerning.A few storms could produce some wind gusts, but the main threat we'll be monitoring will be heavy rain and the potential for low-end flash flooding.

|NOAA/NWS predicts heavy rainfall over the next 5 days south of the Ohio River into the Mid-Mississippi River Valley. The Memphis area could easily see 2-3" of rain with some areas that get thunderstorms receiving more.|
By early next week, high pressure aloft begins to re-build over the region, squashing rain chances and bringing a return of summertime heat. That process will take place gradually the first half of next week.
