NOTE: This information from the National Weather Service was current as of 5 p.m. Thursday.

While the Thursday forecast for the severity of Friday morning's icy weather had lessened from the initial alert, the National Weather Service left a winter weather advisory in place for Tangipahoa, Livingston, St. Helena, St. Tammany and Washington parishes.

The update also turned an eye toward freezing temperatures that will last through the weekend.

Early Thursday, the NWS stated that the likelihood of impactful wintry precipitation had decreased but that minor accumulation of freezing drizzle was still possible 8 p.m. Thursday to 10 a.m. Friday for most of Tangipahoa Parish and 1-8 a.m. Friday in areas south of Hammond.

Lingering ice will likely have melted by 11 a.m. south of Hammond and by 1 p.m. north of Hammond, when the temperatures are forecast to rise to the mid-to-upper 30s.

The precipitation Thursday night may have ended before surface temperatures drop below freezing, but the advisory remained in place since the timing made the forecast "very sensitive to changes," the NWS alert said.

Accumulation, if present, is still most likely to be found on elevated surfaces and bridges. However, even a light glaze of ice can cause travel hazards.

Looking ahead, freezing conditions are expected each night this weekend through Sunday night, with temperatures falling into the low-to-mid 20s in north and central Tangipahoa Parish and into the upper 20s to mid 30s in the south.

These temperatures can damage sensitive agricultural crops and unprotected pipes and will be dangerous for pets living outdoors.

NWS reminds the public to bring outdoor pets inside and to check on the elderly.
