Tonight
As Tropical Storm Bertha pushes northwest, the outer bands will move across the Gulf Coast, bringing showers and thunderstorms in West FL and southern AL, MS, and LA. Localized flash flooding is possible throughout these states. Also, a line of thunderstorms will move into TN during the evening, bringing high winds and possible hail.
Thunderstorms are forming along the cold front moving through the Midwest, which is why there is potential for severe storms in TN tonight. Northern TN is under a slight risk for severe thunderstorms, while southern TN is under a marginal risk for severe thunderstorms. From the evening into the nighttime hours, TN should expect isolated to scattered severe thunderstorms.
As for Tropical Storm Bertha, the most intense winds will be concentrated over western FL, stretching to southeastern MS.
Most of the rainfall will stay just off the coast in the Gulf. Southern LA will receive the most rainfall, with around 1.50 inches, possibly more in localized areas.
Extended Regional Outlook
The CPC outlook has our region experiencing above-average temperatures and near-normal to above-average precipitation from July 29th to August 4th.
Below, we have 3 of the most accurate models blended into one model. This gives us an idea of the possible outcomes from July 29th (7 am) to August 4th (7 am). Based on this blend of models, I agree with the CPC. There are no anomalies in the south, so this would bring the south near normal precipitation conditions. We will still have warm and humid temperatures with the nearby ridge and regular summer conditions. With the shortwave trough set up over the eastern Gulf near the FL Panhandle, this area could see localized thunderstorms that could potentially be severe.
