Discussion

Strong high pressure from Canada will build southeastward over the next 24 hours and this will combine with low pressure off the Mid Atlantic coast to continue a persistent 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 an increasing chance for showers around here as we head into the weekend. 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.
