There is a lull in the action right now across SE PA with respect to today’s precipitation event, but heavy snow bands exist upstream across south-central PA and occasional snow will resume later this afternoon possibly mixed with sleet at times. Snow accumulations are likely from today’s fast-moving low pressure system across SE PA; especially, on grassy surfaces and in higher elevation locations, and some of the snow will may come down quite hard for a brief time. Another snow threat exists for SE PA early Monday as the next system in this active weather pattern approaches the region from the southwest. Furthermore, while today’s system is producing only rain in the DC metro region, this next system could produce snow as far south as DC come late Sunday night/early Monday at the onset of the next precipitation event. Eventually milder air will cause a changeover of the snow to sleet and then to plain rain later Monday and the rain will likely fall quite heavily at times from Monday night into early Tuesday as a strong cold front plows towards the east coast. That cold front will usher in more cold air for the Mid-Atlantic region and the remainder of the month of March continues to look quite a bit colder-than-normal with no sustained spring weather in sight.
