Lafayette County Tornado Watch Canceled, Freeze Warning Now in Effect

A tornado watch that had been in place for Lafayette County on Sunday, March 15, was canceled, and frigid temperatures quickly became the more pressing concern as the National Weather Service put a freeze warning and subsequent freeze watch into effect across the area.

The freeze warning ran from 4 a.m. through noon on March 16, according to the National Weather Service. That evening, at 8 p.m., a freeze watch took over, remaining in effect through noon on March 17. The Lafayette County Sheriff's Office posted notice of the tornado watch cancellation and the incoming freeze warning on social media, alerting residents to the shifting threat.

NWS bulletins covering southeast Mississippi warned of sub-freezing temperatures as low as 29 degrees Fahrenheit. The impacts outlined by forecasters extended beyond personal discomfort: frost and freeze conditions carried the potential to kill crops and other sensitive vegetation, and could damage unprotected outdoor plumbing. The broader regional alert picture, drawn from NWS offices in both Mobile, Alabama and New Orleans, Louisiana, placed southeast Mississippi within a freeze warning valid through 8 a.m. on March 18, part of a wider Southeast freeze event affecting portions of south central and southwest Alabama and northwest Florida as well.

The whiplash from tornado threat to hard freeze reflected a stretch of unstable mid-March weather across north Mississippi. Conditions at the time of the alerts showed temperatures in the low 40s under clear skies, with a northwest wind at 3.6 mph, offering little insulation against the overnight drop forecasters were projecting.

The National Weather Service advised residents to take precautions against the cold, including protecting outdoor plumbing and bringing in or covering sensitive plants before temperatures fell below freezing.
