Ice Storm — Jefferson Davis, Louisiana

2021-02-17 · Jefferson Davis, Louisiana

Event narrative

Freezing rain pushed into the region before sunrise on the 17th. Up to 1 tenth of an inch of ice had accumulated by noon when temperatures rose above freezing as low pressure moved in from the Gulf of Mexico.

Wider weather episode

The first in a series of Arctic Cold Fronts arrived during the 12th pushing tide levels down along the coast, however the subfreezing temperatures and winter weather did not arrive until the 14th. The event on the 14th began at many places as a light glaze of freezing rain, but quickly changed over to sleet or snow. Another round of winter weather occurred on the 17th, however this round was mainly freezing rain. The long duration event set many records in the area and rivaled the historic freezes of the region. The event was likely the longest and coldest since December 1989.
