.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. Ahead the low and cold
front, a warm front will lift north of the area this morning.
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.
