Discussion
Weak low pressure will push across the Mid-Atlantic region today and result in a relatively minor snow event and primarily to the south of the PA/MD border. Clouds will rapidly increase this morning and snow should break out in the mid-to-late afternoon hours and continue into early tonight. Small accumulations of a coating to an inch or so are possible from this system in the southern and western suburbs, but roads should hold up pretty well given the borderline afternoon temperatures and daytime snowfall. After a dry day on Saturday, a more important system with more moisture will push rain into our region later tomorrow evening and it could start as a wintry mix in the normally colder higher elevation suburban locations. The rain will end early on Sunday and afternoon temperatures could end up not far from the 60 degree mark with breezy and mainly cloudy conditions. A strong cold frontal passage will usher in colder air on Monday and it'll stay moderately cold on Tuesday and Wednesday. Elsewhere, another major snowstorm will take place this weekend in the Northern Plains and there will likely be another severe weather outbreak on Saturday across the Lower Mississippi Valley including possible tornadic activity.
