As of Monday morning, weather models continue to show a storm developing over the Gulf of Mexico on Monday, then tracking off the North Carolina coast on Tuesday. At the same time a cold Canadian air mass will be building along the east coast Monday into Tuesday.
Right now the bulk of the weather data suggests a cold rain event for a large portion of eastern Carolina. Temperatures may be cold enough initially for a brief period of snow or sleet before the changeover to rain, but this is for NW & inland locations (See Graphic). If those areas do see any wintry precipitation it would likely result in very little accumulations on grassy surfaces.
As is always the case with our snow chances, the forecast may change a bit before tomorrow, but not much. If the storm tracks closer to the coast, milder marine air would likely ensure all rain for all areas. A track a little further offshore would increase the probability for wintry precipitation. If the storm stays too far offshore most of the weather would miss us altogether. We will continue to keep a close eye on how the weather models evolve in the next few days and adjust the forecast accordingly.
Although it's very late in the season to be talking about snow, it is not unprecedented. 31 years ago, on March 24th and 25th of 1983 we saw 4 to 8" of snow over counties along and west of highway 17.
Some areas even reported a few inches of snow as late as April 11th in 1988.
