DISCUSSION

KEY MESSAGE 1...Above normal temperatures, at least 5 to 10 degrees above average, expected Tuesday through late week.

KEY MESSAGE 1 DESCRIPTION... A large high pressure system will move east across the Mid Atlantic coast and out to sea on Tuesday. Areas to the N of the high will be influence by the WSW flow. This will bring mostly sunny skies and warm temps, at least 5 to 10 degrees above normal for this time of year. However, the SW flow will keep coastal temps much lower due to the sea breeze. The hot weather, combined with some modest instability and weak low pressure waves moving through the area, should also help to develop some isolated to scattered showers and thunderstorms each afternoon beginning Wednesday and continuing through the end of the week. No severe potential is expected at this time due to the limited instability.
