.SYNOPSIS...
A backdoor front will push into the waters this evening, shifting
prevailing wind to northeasterly Tuesday and Wednesday. The onshore
flow will keep thunderstorm activity well inland through the middle
of the week. The front will settle south of the waters through
Saturday before it lifts back northward into the area as remnant
inverted trough Thursday resulting in an increase in rain and storm
chances. As surface high pressure builds to the south, a weak
southwesterly flow will develop into the Independence Day holiday
weekend and increase chances for thunderstorms.
