Three chances for wintry precipitation

Freezing Rain Potential Overnight

THE BIG PICTURE - Cold air has moved in and it will actually get colder through late week. That leads to two chance for wintry precipitation over the next week.

THURSDAY NIGHT - FRIDAY MORNING - Late tonight into early Friday morning a storm system will pass well off the coast. There could be just enough moisture along the south end of the Grand Strand to produce some patchy light freezing rain or sleet. Little or no accumulation is expected, but even the lightest glaze on bridges and overpasses can cause travel issues. For that reason and out of an abundance of caution, the National Weather Service has issued a WINTER WEATHER ADVISORY for Georgetown county from THURSDAY 10pm - FRIDAY 9AM. Keep in mind, it is still entirely possible we don't get any precipitation.

MONDAY - If I had a nickel for everytime a forecast model predicted snow for the Carolinas and it didn't snow, I would retire right now as a very wealthy man. 9 times out of 10, snow in the long range doesn't actually happen here. Over the past 24 hours, the models are in much better agreement and consistently showing no snow in our area. I'll keep the chances at 20% for now, but if the trend continues, I'll take precipitation completely out of the forecast.

WEDNESDAY - Once again, we have a situation where one forecast models is showing snow while the other nothing at all. The disturbance that COULD produce a storm is still in the middle of the Pacific ocean where there is very little data. In other words, no one is launching weather balloons out there to sample the atmosphere to properly determine the size and strength of the disturbance. If data going into a forecast model isn't providing an accurate depiction of the atmosphere, then you can bet the forecasts produced by that model will be off and change considerably. We'll see how things trend through the weekend before I get excited about snow. At this point, snow is possible, but so is nothing at all.
