Snow could fall on South Mississippi this week. But it may get even colder after that.

Snow could fall in South Mississippi this week, the Harrison County Emergency Management Agency warns.

A much-anticipated cold front is expected to quickly drop temperatures and bring rain showers on Wednesday. The National Weather Service in New Orleans predicts a continued flow of moisture to the Coast and freezing or near-freezing temperatures, which would bring a mix of rain with sleet or light snow.

The best chance for “light winter precipitation” is Thursday night into early Friday morning for areas north of Interstate 10, the Harrison County agency said.

The forecast is still very uncertain, but “minor accumulations can not be ruled out over elevated surfaces Friday morning.”

The weather service also advises an “even stronger cold front” is expected Friday, and wind chill could send temperatures into the 20s.

“Many areas across the north half of the forecast (area) will experience morning lows in the 30s Thursday through next Monday and below normal temperatures Wednesday through Monday.”

Falling temperatures will be noticeable by Wednesday and chance of rain is 90 percent, rising to 100 percent Wednesday night with a low around 40. Thursday has a 70 percent chance of rain, falling to 60 percent at night with an overnight low around 35.

Rain chances remain high, about 80 percent on Friday, when some snow showers could happen before 9 a.m. Skies should clear by Friday night, when temperatures are expected to be the lowest of the week, around 31. Saturday and Sunday highs are expected to only right the upper 50s with lows in the mid 30s. And Monday should start the warming trend with a high in the mid 60s and low near 40.
