Marine Weather and Tide Forecast for Marumsco, VA

NEAR TERM /THROUGH TONIGHT/
Temperatures are steadily increasing early this afternoon, now in the 70s across the area. Expect upper 70s to low 80s for mid to late afternoon. A warm front that lifts through the area will keep conditions mild tonight, with lows in the 60s.

Breezy conditions are expected this afternoon and early evening, with gusts around 25-30 mph. In the VA/MD Piedmont and some of the mountains locally higher gusts around 35-40 mph are likely for a few hours. Winds decrease after sunset, though breezy conditions continue through the night (gusts around 15-25 mph).

SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/
A sharpening mid-level ridge over the Southeast U.S. nudges its way toward the Mid-Atlantic on Saturday. This is going to produce the warmest day of the year so far, with highs reaching the mid to upper 80s. A cold front approaches from the OH Valley, though the ridge is likely to keep this system well north/west of our area. Isolated to scattered showers reach the Alleghenies Saturday night, otherwise we remain dry east of the mountains. Still mild Saturday night with lows in the upper 50s to mid 60s.

The front moves into the area Saturday night into Sunday. The main impact from this is expected to be less warmer temperatures and cloudy skies for Eastern Sunday. Highs are forecast to be in the 70s, though a few spots in Central VA could reach 80F and those in Northeast MD struggling to reach 70F. Easterly flow returns Sunday night with lows in the 50s.

LONG TERM /MONDAY THROUGH FRIDAY/
A surface low pressure system will track NE across the Great Lakes on Monday with the associated cold front pushing through the forecast area Monday night. As the cold front moves through the area, precipitation chances increase with rain showers possible. The more favorable conditions for convection will remain to our west, although isolated thunderstorms are possible.

In the wake of the frontal passage, high pressure builds over the Mid-Atlantic through midweek. Conditions dry out Tuesday as cloud cover decreases. As high pressure shifts offshore, southerly flow ushers in moist air aloft with cloud cover expected to increase.
Additionally, a cold front approaches from the northwest with low end PoPs forecast throughout the day on Thursday.

High temperatures will be in the 70s to low 80s each day with overnight low temperatures in the 50s (40s in the mtns) for most.

VFR conditions are expected through the weekend. Gusty southerly winds around 25-30 knots this afternoon, diminish to around 20 knots tonight, then increase again to 20-25 knots Saturday afternoon. Winds diminish Saturday night into Sunday.

As precipitation chances increase overnight Monday into Tuesday, sub- VFR conditions are possible. Southerly winds on Monday shift to westerly on Tuesday.

MARINE

Winds slowly shift from south today to southwest on Saturday. Winds diminish Saturday night as a cold front moves south into the area, causing winds to become northerly, then easterly by Sunday evening.
