Discussion

Arctic air has pushed into the Mid-Atlantic region and temperatures today will do no better than the lower 30’s for highs and temperatures will plunge to bitter cold levels by early tomorrow not far from 10 lonely degrees in some spots. Winds will be noticeable today out of the northwest making it feel even worse that the actual air temperatures. High temperatures on Saturday will again be confined to the lower 30’s - well below-normal for this time of year where the normal high in Philly is 43 degrees. Strong high pressure will then push off the east coast late Saturday and temperatures will ease on Sunday with highs back in the 40’s and the 50’s are likely again early next week. One final note, the rocket launch that was originally scheduled for late Sunday afternoon at NASA’s Wallops Island Facility has been rescheduled for this afternoon at 3:43 PM and it may be visible throughout the Mid-Atlantic region. The original launch was scrubbed due to a faulty sensor issue which should be resolved by week’s end. Weather can be an issue as winds will be quite gusty out of the northwest throughout the Mid-Atlantic region.
