Updated models predict snow for the Lowcountry, but disagree on everything

CHARLESTON, SC (WCSC) – Two forecast models demonstrate the uncertainty in the range and humidity that will determine how much wintry weather the Lowcountry sees starting Tuesday.

Live 5 First Alert meteorologist Chris Holtzman said it now looks like snow will be the primary type of precipitation, although some forecasts call for more of a mix, which would reduce the amount of accumulation.

But how much accumulation is possible? That, he says, depends on the forecast models, which were still varying drastically as of early Sunday morning.

The most extreme predicted between 1 to 5 inches for the Lowcountry, while another predicted less than an inch total.

Live 5 First Alert meteorologist Bill Walsh said wintry weather will affect the area Tuesday and Wednesday with a possible second shot coming Thursday when another wave passes to the east.

Before the wintry precipitation, an arctic blast will move in on Monday and last through next week. Sunday’s high of 65 degrees will give way to a temperature of just 41 degrees on Monday, with the temperature dropping to 25 degrees on Monday night.

The storm system that will deliver the wintry precipitation is set to arrive Tuesday afternoon and continue to affect the area through Wednesday morning. Walsh says it will be a fast-moving system.

The team declared Tuesday, Wednesday and Thursday as First Alert Weather Days because of the chances that parts of the Lowcountry could see wintry weather.

Any impact on travel could be felt from Tuesday afternoon, he says. Any precipitation that melts during the day freezes overnight when temperatures drop below freezing.

Lowcountry school districts have not yet announced plans on whether to hold classes or switch to eLearning days due to the wintry weather.

Those decisions are expected to begin coming over the next few days as the track of the storm continues to come into sharper focus.
