Cold weather pattern for D.C. boosts snow chances, starting Sunday.

Several models show the possibility of a storm Sunday into Monday.

The first 10 days of January produced nearly 10 inches of snow in Washington and the weather pattern for the next two weeks may be promising for more. The next chance of snow forecasters are watching is Sunday into Monday.

Computer models show the possibility of another storm coming up from the south. The big question is whether the storm, as it tracks toward the Carolinas, comes up the East Coast and socks us with heavy precipitation or turns out to sea leaving us mostly dry.

If the storm comes up the coast, it could be a substantial snow producer although there’s also some chance it draws in enough warm air for a wintry mix or even cold rain.

It will take at least a couple of more days to have a good idea what scenario is most likely.

At the moment, we’d say there’s about a 40 percent chance of at least an inch of snow and 20 percent chance of at least 3 inches. These numbers are on the conservative side because the storm system is still about six days away and a lot of ingredients have to come together for this storm to meaningfully affect the area.

As of Tuesday afternoon, three of four major modeling systems simulate a major storm affecting the Mid-Atlantic on Sunday into Monday. Here’s what they are projecting:'>>>

2. You're welcome, friend.

'At least' we've been warned.

3. As my father said decades ago, those were the ones to watch out for.

My maternal grandmother was born in Illinois. She'd always watch the storms coming in from the Midwest. My father held that it was the storms coming up from the South that were the ones that brought the big snow.
