Marine Weather and Tide Forecast for Aquia Harbour, VA

NEAR TERM /THROUGH WEDNESDAY/
Clouds remain across the bay associated with a departing area of low pressure. Continued clearing is expected overnight to the east, while clouds increase to the west in the Alleghenies.
Much drier air moves in tonight as a dry cold front approaches.
This will bring cooler air into the area as well. Lows will fall into the mid/upper 40s west of the Blue Ridge and low 50s to the east.

SHORT TERM /WEDNESDAY NIGHT THROUGH THURSDAY NIGHT/
The aforementioned moisture starved cold front makes its way through the area during the day Wednesday. Temps will be warmest to the south of the front, in the low to mid 70s south of I-66. To the north, cooler air prevails keeping highs in the upper 60s to around 70F. Breezy conditions again due to downsloping northwest winds gusting around 20 mph during the afternoon. Did lower Tds a tad behind the front given forecast mixing.

Turning colder Wednesday night through Thursday night as Canadian high pressure builds into the region. Lows Wednesday night drop to the 30s to mid 40s across the area. A few spots in the Alleghenies could get close to freezing, mainly the valleys where the winds likely decouple. Widespread frost is not likely Wednesday night due to a persistent, though light, northwest wind.

Sunny and cool Thursday with highs in the low to mid 60s. Main concern Thursday is the potential for some fire wx concerns depending on how dry the forecast trends. Winds are borderline for SPS (~20 mph). Will continue to monitor.

The coldest temps of the week are likely Thursday night as the high settles over the eastern OH Valley to PA. Lows likely drop to the 30s everywhere west of I-95, and the low 40s to the east.
Much better setup for frost/freeze Thursday night with the high overhead. Frost and freezing temps are possible, especially along/west of US-15.

LONG TERM /FRIDAY THROUGH TUESDAY/
High pressure will be overhead Friday before slowly working eastward on Saturday. Dry conditions will continue with some warm advection increasing some clouds along the way Friday night into Saturday. Near normal temperatures Friday will rise above normal on Saturday.

A trough will dig toward the eastern US as a closed low moves across the northern Plains toward the eastern Great Lakes Saturday into Sunday. A surface cold front will race eastward across the Great Lakes and eastern Ohio Valley Sunday and bring a chance for showers and possibly a thunderstorm. The threat for showers or a thunderstorm could linger into Monday depending on the speed of the cold front. Temperatures will drop back below normal Monday behind the front.

AVIATION /00Z WEDNESDAY THROUGH SUNDAY/
