Today through Thursday...

Warm humid conditions are expected to persist through the day today 
as the high off to our east continues to funnel in onshore flow from 
the Gulf. A low that is moving towards Wisconsin has trailed a cold 
front through our northwestern peripheries, causing a thin line of 
rain showers. This front will progress partway through the region 
today allowing for widespread showers and embedded thunderstorm 
development, fueled by the ample moisture that has settled into the 
region over the last week or so. Expect those showers to develop 
across most zones by the afternoon and transition to embedded 
thunderstorms thereafter. This setup will persist through the rest 
of the day as the front stalls across the CWA. That being said, 
locally heavy rain is possible with this continuous rainfall so 
caution is advised when travailing on more rural thoroughfares 
today. A marginal potential for a few severe thunderstorms can not 
be ruled out with this system through much of south and central 
Mississippi; however, shear values indicate that any strong/severe 
storms that do develop in this area will be short lived. While the 
front is set to push into the area a bit more today its slow 
plodding pace will eventually stall through central Mississippi by 
tonight. Thunderstorm activity will transition to showers overnight 
tonight, and this general pattern of daytime thunderstorms and 
nighttime showers will persist through Thursday.

Friday onwards...

The front will begin to erode by Friday morning, bringing forth a 
cessation of showers through the southeastern half of the area. 
Northwestern portions will maintain the cyclical forecast lined out 
above. There could be a few upper level disturbances that transit 
the area over the weekend that could force a reorientation of the 
surface front and attendant upper level dynamics, that causes a 
subsequent reorientation of showers and thunderstorms. In general, 
northern zones will remain wet, and southern zones will see some 
short-lived relief from continuous rainfall./OAJ/
