.SYNOPSIS FOR THE TIDAL POTOMAC AND MD PORTION OF THE CHESAPEAKE BAY...
A warm front will lift northward through the area today, before a
cold front moves through tonight. A strong area of high pressure
will build to our north tomorrow and remain in place through much of
the week, leading to a prolonged period of onshore flow. Small
Craft Advisories will likely be needed for much of the Monday
through Thursday time period, and a few low-end Gale gusts can't be
ruled out on Tuesday or Wednesday.
