224 PM EDT Mon May 25 2026
.SYNOPSIS...
A stalled frontal boundary stretching across the Mid-Atlantic states
and the Ohio, Tennessee and lower Mississippi Valleys will lift
slowly northward tonight and Tuesday as Atlantic high pressure
centered near Bermuda expands westward towards the southeastern
seaboard. Breezy southeast to southerly winds will continue through
midweek across our local waters, with Caution conditions prevailing
during the afternoon and evening hours as wind speeds surge to just
below Small Craft Advisory levels. High pressure positioned off the
southeastern seaboard will weaken later this week as a cold front
shifts southward towards our local waters during the upcoming
weekend. Scattered showers and thunderstorms will tend to develop
during the overnight and morning hours on Tuesday and Wednesday,
with activity then increasing in coverage and frequency from Friday
through the upcoming weekend.
