Rain and lingering cold in parts of Maryland could spell trouble for late-night (or early-morning) motorists tonight as a storm system moves in from the Ohio Valley. The National Weather Service has issued a freezing rain advisory for the northern tier of counties, from Harford west to Allegany. Normally colder valleys may be especially vulnerable.

Heading north? There are winter storm watches and warnings up for eastern Pa., northern N.J. and the NYC area. That means 4 inches of snow or more. Click here.

Things should warm up here in the morning - at least enough to erase the ice threat. And the rain will cease. But it won't be anywhere near the balmy 65 degrees forecast earlier in the week. The cold air to our north has lingered more than forecasters expected, and the warm weather to our south will stay there, holding temps here to about normal for this time of year - mid-to-upper 40s in the daytime, 20s at night.

But once we're clear of the rain tomorrow, the sun will come out, and stargazing should be good for the weekend. And forecasters seem confident that the coastal low that's expected early next week will not push far enough north to affect our region. If it does, cold air here could mean frozen precipitation.
