Today through next Tuesday night:

An upper-lvl/surface ridge continues to shift eastward, resulting in another quiet and humid day for the ArkLaMiss region. Patchy fog will be possible across south/southeast MS around sunrise. By this evening, rain chances are expected to return as several shortwave disturbances begin to progress through the area. In addition to the shortwaves, a slow-moving cold front to the northwest will push southward over the next couple of days.

Wednesday night, CAMS are showing a remnant MCS from the mid-west, pushing into the region during the overnight hours. This activity is expected to diminish as it moves eastward. Re-development of afternoon showers/storms will be possible Thursday. Should the airmass recover from overnight rainfall, sufficient deep-layer shear, SBCAPE, and lapse rate could promote some strong to severe storms. As a result, a "Slight" risk for severe weather areas along and north of Natchez Trace was introduced by SPC. Damaging wind gusts and hail (up to quarter-size) will be possible. Will update the severe HWO graphic to include the "Slight" risk and HWO graphic for "limited' fog remain unchanged. Shower/storm chances will continue into Friday as the frontal boundary progress towards the southeast but severe weather isn't anticipated at this time. Rain chances are expected to end as the boundary push toward the Gulf coast; however, models are uncertain if another shortwave disturbance will develop and keep rain chances through Saturday afternoon.

Once the front pushes through, high pressure is expected to center over the Ohio Valley through the weekend, bringing quiet conditions along with seasonal average temps to the CWA The aforementioned high pressure will gradually move eastward and allow for rain chances to return near the end of the period. /SW/
