A cold front will pass through South Mississippi by Monday morning bringing a few light showers and cooler temperatures. Patchy fog will be possible ahead of this front. Low temperatures Monday morning will be in the 50s. Highs in the low 60s with mostly cloudy skies. Some sunshine is possible by the afternoon, especially north of I-10. The cool spell is short lived as warm, moist air returns Monday night ahead of another system approaching from the west. This will bring the chance for off and on showers each day this week, with perhaps our best chance for heavier downpours being on Wednesday.
