9/6 – Brittany’s “Mostly Cloudy” Tuesday Evening Forecast
Mississippi is still under the influence of upper level troughing which is slowly moving east while further west has a large ridge with a cutoff low. This trough has been the primary driver of our current unsettled weather with large cloud deck with showers and thunderstorms over much of southern Louisiana. For the most part, storms have primarily remained over the Gulfwaters where some storms have been able to crop up. While these storms could be extremely efficient rainmakers, have not really seen this materialize today due to lower coverage of showers/storms over land along with relatively fast storm motions. Expecting a similar diurnally driven trend tomorrow as well.
Starting around Thursday, the upper level trough develops into an upper level low centered around the northern Gulf coast. Where precisely this said low develops will make a difference whether or not we`ll be wetter or drier forecast wise. One option is the low develops further east of us, which gives us that onshore flow bringing plenty of moisture from the Gulf into the area. The alternate is if it ends up west of us, drier air from inland would help cut down on PoP chances.
