Snow for midweek: Barely any or inches?

Most weather models call for little or no accumulation when possible snow comes late Tuesday or early Wednesday, but a model produced by meteorologists in Europe is less rosy.

The region will get a little warmer as the week begins, and we may have a dusting of snow in store at midweek. Or maybe more than that.

The National Weather Service office in Raleigh is calling for precipitation -- if it appears to begin as rain late Tuesday because the forecast high that afternoon is in the mid to upper 40s.

As the thermometer falls back toward freezing during the night, however, there is about 50-50 chance of snow, the weather service said.

No accumulation is likely, though. Or so say most of the computer weather models.

But, as ABC11 meteorologist Steve Stewart said Sunday, that verdict is not unanimous, and the calculations known as the European Model is saying the area might see a few inches.

That model, Stewart said in his online forecast, has “also been the most consistent with the snow coming in on the heels of another Arctic Front.”

Air coming from our northwest usually loses its moisture as it goes up over the mountains, Stewart explained, but the cold air moving in on Tuesday may have more to it than usual.

The European model also says a low-pressure system might form off the coast, and that would add moisture to the cold air.

Sunday, mid-afternoon temperatures were sitting a little under freezing in most of the Triangle. There were slightly higher readings to the south and slightly lower ones tho the west.

Overnight lows this week are slated to be below freezing, with the possible exception of Tuesday night.

There is no question that it’s still winter, and an unusually cold one. Normal overnight lows at Raleigh-Durham International Airport in mid-January are degree or two below 32, but the temperatures Sunday night, Monday night, Wednesday night and Friday night will be more like 18 to 22 degrees, the weather service said.

Historically, daytime high temperatures now average around 50 degrees.
