Mississippi – Frost clings to rooftops and windshields this morning as Jackson wakes to a quiet but chilly December start. The air feels crisp now, but wetter and warmer weather is already lining up later this week.
According to the National Weather Service, patchy frost developed early, mainly before mid-morning, with temperatures hovering in the mid-30s. Drivers should watch for slick spots on bridges and shaded roads, especially during the early commute. Scraping windshields may be needed before heading out.
Clouds increase as the day goes on, but conditions stay calm. Highs rise into the mid-50s, keeping the daytime feel cool but manageable. Tonight turns cloudy again, with temperatures settling near the low 40s.
By Wednesday, Jackson warms noticeably. Afternoon highs climb into the low 60s, and humidity begins to increase. A few light showers are possible later in the day, signaling a pattern shift. Roads may turn damp at times, though widespread impacts remain limited for now.
The main weather change arrives Thursday, December 18th. Showers become more likely by afternoon, with embedded thunderstorms possible after mid-day. Gusty winds could reach 20 mph at times, and brief heavy rain may reduce visibility. Wet pavement could slow traffic during peak travel hours.
Behind the rain, slightly cooler air filters back in Thursday night. While a hard freeze is not expected, temperatures dip into the upper 30s, which could create slick spots where water lingers.
Friday turns drier and brighter. Sunshine returns, with highs near 55 degrees and lighter winds. The weekend looks favorable for travel and outdoor plans. Saturday and Sunday stay mostly sunny and warm, with highs pushing toward the upper 60s by Saturday.
Looking ahead to Christmas travel week, this frost-to-rain pattern is an early sign of winter’s back-and-forth grip across Mississippi.
