Issued at 359 AM CDT Mon Apr 21 2025
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/
