.WHAT HAS CHANGED... Winds are going to be close to Small Craft Advisory conditions, though most likely fluctuate between 15-20 knots this afternoon. Marine Weather Statements or Small Craft Advisories could be issued later this morning. Strong to severe thunderstorms possible this afternoon/evening, though coverage will be low. Higher chances for severe thunderstorms Friday and Saturday.

.KEY MESSAGES... - 1) Hot, humid conditions persist into next week, along with daily chances for shower and thunderstorms.

KEY MESSAGE 1...Hot, humid conditions persist into next week, along with daily chances for shower and thunderstorms.

The Bermuda High remains in place across the western Atlantic into next week. PWATs (Precipitable Waters) will be near or greater than 2" in the valleys with 1-2" in the mountains. South to southwesterly flow is maintained over the Mid-Atlantic. Hot and humid conditions each afternoon, with highs reaching the upper 80s to low 90s, and heat indices in the low 100s each of the Blue Ridge.

A surface trough is forecast to remain over the area through Friday. Aloft, pieces of shortwave energy continue passing overhead and help trigger scattered showers and thunderstorms each afternoon. Deep layer shear is forecast to increase through the weekend as the subtropical jet stream strengthens. Hotter conditions may cause relatively steeper low-level lapse rates and the wind field strengthens a bit (especially Friday). This is going to bring an increasing chance for strong to severe thunderstorms each day, with Friday and Saturday looking to have the highest chances. On Saturday, a more potent shortwave trough is forecast to move overhead that could aid in stronger, more organized severe convection. Damaging wind gusts will be the main threat.

A quasi-zonal flow aloft will develop Sunday into into next week. Sunday could bring a short reprieve as dry conditions prevail. Seasonably hot, humid conditions along with daily chances for showers and thunderstorms return Monday through most of next week.

Marine
Small Craft Advisories could be needed for parts of the waters at times through Saturday, mainly in the late afternoon to evening. Otherwise, winds remain around 10 knots. Daily showers and thunderstorms expected each afternoon into next early week. Special Marine Warnings would accompany any of the stronger thunderstorms capable of producing frequent lightning and wind gusts over 35 knots.

Tides / Coastal Flooding
Anomalies climb late this week in response to return southerly flow. Periods of coastal flooding are possible at times of high tide at sensitive locations.
