Alberta Clipper tracking eastward across western PA is weakening as supporting upper level trough weakens and opens up so we are not expecting much in the way of precipitation in Baltimore.
Sunday will turn out more tranquil than Saturday, certainly the “better day” of the weekend.
Unusually warm air will get pushed northward today on a southerly wind.
The first half of the day will be a little icy.
The last time it has been this cold is 8 degrees on Jan 24, 2011.
Rain moving northward. There will be strong low-level warm air advection over the mid-Atlantic Sunday afternoon.
Today certainly the pick of the weather through the forecast period for those who like things on the mild, dry and sunny side.
Numerous high temperature records were broken Saturday across mid-Atlantic and
parts of the Northeast.
With calendar Winter officially arriving at 12:11 p.m. this afternoon, it’s only fitting that the temperatures challenge the record highs for the weekend.
Very little snow accumulated in Baltimore Saturday afternoon before the snow changed to rain. However, just west and north of town there were reports of 1-3″, with the 3″ amounts along the Mason-Dixon Line.
Looks like the way things are shaping up with most of the precip, at least for BWI Marshall where it’s spotty and light, we have to wait until about afternoon to get into the shield of precipitation as moistening in the warm advection zone continues.
It is cold enough for precipitation to start out as snow, which is expected to begin mid- to late morning.
