.SYNOPSIS...
A strong low pressure system will move across the southeast states
today with an associated cold front and pre-frontal squall line
expected late this afternoon and evening. Strengthening south winds
and building seas today will support Small Craft Advisory across all
waters with potential for gale force gusts. The cold front
associated with the low will send the squall line of showers and
thunderstorms through the waters late afternoon and evening. A few
strong to severe storms are possible with this line of storms. High
pressure ridging will then build back down the southeast coast on
Monday before weakening and shifting east of the Florida Peninsula
once again mid week.
