Another round of winter weather

A hazardous weather outlook was issued Tuesday morning by the National Weather Service for Forrest, Lamar, Jones Lincoln and Marion counties.

The outlook warns of low temperatures near or below 20 degrees Tuesday night. Hypothermia is possible with prolonged exposure and there will be a possible danger to exposed pipes.

Sub-freezing temperatures through Wednesday morning may limit the melting

potential in parts of the region, and puddles of melted ice and sleet may refreeze overnight and cause areas of slick black ice on roads and bridges, NWS reported.

Another winter storm is expected Wednesday morning through Thursday, NWS reported, which could result in dangerous travel conditions and numerous power outages. This winter storm will result in significant icing and snow accumulations for portions of extreme southeast Arkansas, northeast Louisiana and west-northwest Mississippi.

Areas of South Mississippi are expected to see a mix of precipitation on Wednesday followed by rain Wednesday night.

The Mississippi Emergency Management Agency said the storm system could result in possible severe weather across portions of the Pine Belt and the coastal counties. 

The Pine Belt is at a marginal risk with the main threat forecast to be damaging wind gusts.

On Wednesday, there is a chance of sprinkles and flurries before 11 a.m., then a chance of sprinkles between 11 a.m. and noon with rain showers likely after noon. The expected high is near 48. The chance of precipitation is 60%. with new precipitation amounts of less than a tenth of an inch possible.

Wednesday night there will be showers and possibly a thunderstorm with a low around 35. Winds could gust as high as 20 mph, and the chance of precipitation is 100%. New rainfall amounts between three quarters and one inch are possible.

Coldest Feb. 15 on record

According to data from NWS, Monday was the coldest Feb. 15 on record for Hattiesburg with a low of 20. The second coldest Feb. 15 on record was in 1960 when the low was 25.
