Winter Weather Advisory for Mardi Gras

Although it's March and Mardi Gras, it seems this winter has known no bounds....and no end.

A Winter Weather Advisory was issued for Acadiana Monday afternoon from 3:00am through 12:00pm Tuesday.  The advisory could expand or be upgraded to a Winter Storm Warning if trends warrant the status change through Tuesday morning.

A fast moving upper level disturbance will approach Louisiana overnight through Tuesday as cold air settles into the region. This disturbance will likely produce patchy sleet, freezing rain and plain old rain for Acadiana's Mardi Gras.

Temperatures will be right near freezing through midday Tuesday so any precipitation that falls could potentially freeze on the surface (mainly bridges & overpasses) but totals are expected to be light/low, thus the advisory...for now.

There may be a few hours where icy conditions could develop especially along and north of the I-10 parishes...as always with winter weather systems in Acadiana, there is little indication on "if" and "where" any icy conditions could develop until the actual precipitation is on the local radar.

In general a glaze of 1/10th of an inch will be possible, but models late Monday evening were "icier" showing 1/4" or more possible, which could certainly lead to hazardous travel.

Temperatures should get above freezing (but stay in the mid-upper30s) for the afternoon as precipitation ends quickly.

Milder conditions are expected for the latter part of the week into the weekend as highs get back into the 70s Saturday...Louisiana weather!
