WEATHER BLOG: Chilly Rain
The latest storm that is sliding along the Virginia-North Carolina border Tuesday morning is going to bring varying types of precipitation to the area. First of all, we need to made it clear that Baltimore and most places located near I-95 are probably just going to see rain, which has already started in many places. But, while the Inner Harbor was 45 degrees as of 4 a.m., York, Pa was in the mid 30s, and there will be several places less than 40 miles from the Baltimore City that will get an accumulation of wet, slushy snow.
A Winter Weather Advisory has been put up for Frederick and Carroll counties until noon, because there will be a general 1-2 inches of “slop.” The advisory in York County, Pa. runs until 1 p.m. and they will probably see even more (3 or 4 inches).
Temperatures will hover in the low and mid 40s at BWI, but it will obviously be no higher than the 30s well north and west of the city. All precipitation will come to an end Tuesday afternoon from west to east. But, we should then be talking about temperatures dropping to near freezing later Tuesday night in many of the larger cities and the 20s farther inland, because any untreated surfaces could become icy overnight, and some slush could freeze. Behind this wave of low pressure late Tuesday and Wednesday, there will be a fresh injection of chilly air invading the Northeast and the mid Atlantic states.
