DISCUSSION
Issued at 115 PM CDT Tue Mar 17 2026
Tonight through next Monday...Under continued northwest flow aloft, high pressure at the surface is settling into the region. Another chilly night will prevail across the forecast area tonight, but not as cold as last night. This is thanks in large part to a mid/upper level disturbance passing to our north. This will result in increasing cloud cover over mainly central and northern portions of the CWA overnight.
Although temperatures will moderate up, lows Wednesday morning will range from the lower 30s across the eastern half of the forecast area to around 40 across areas along and west of the Mississippi River. This, coupled with calm winds, could lead to some patchy frost forming, particularly across east and southeast Mississippi. However, the aforementioned cloud cover could put a hamper on this. Where ever any frost indeed forms, it could once again result in some minor damage to sensitive and unprotected vegetation.
The weather overall remains quiet this weekend into early next week. Temperatures will steadily rebound during this time, with highs eventually climbing back to above normal readings and into the 80s Saturday through next Monday. Lows will likewise follow suite, but remain cool through the period. Come this weekend into Monday morning, lows too will be above normal as they struggle to fall out of the middle and upper 50s. /19/
