Discussion
Strong high pressure from Canada is building southeastward and will combine with low pressure off the Mid Atlantic coastline to continue to produce an onshore flow of air into our area. The low pressure system will push slowly northwestward over the next couple of days and the result will be periods of rain in the DC metro region this upcoming weekend and perhaps lingering into Monday as well. Coastal locations could experience above-normal high tides, rip currents and even some beach erosion over the weekend given the expected long-lasting onshore flow of air and these effects will be exacerbated by the full “supermoon” which takes place on Sunday.
