Discussion
Many ingredients are coming together for a very active Arctic frontal passage this weekend that will include rain transitioning to accumulating snow/sleet on Saturday and high winds and very cold conditions on Saturday night and Sunday. The rain will begin late tonight and continue for awhile on Saturday morning and then transition to snow in the late morning following the passage of the Arctic front. This transition to snow may include some sleet and will will progress from west-to-east across the Mid-Atlantic region. Wind gusts of 50+ mph are possible later Saturday and Saturday night and that kind of intensity raises the possibility of downed tree limbs and power outages in the Mid-Atlantic region. The weather will calm down some by later in the day on Sunday, but it’ll remain much colder-than-normal for this time of year and then a warm up begins on Monday.
