Marine Weather and Tide Forecast for Sykesville, MD

SHORT TERM /THROUGH FRIDAY NIGHT/
A very dry airmass resides over the region as subsidence continues to dominate on the north side of an area of low pressure slowly moving offshore the VA/NC border. This can be seen in the subsidence inversion in the 12z IAD RAOB, as well as decreasing cloudcover across the region in satellite imagery.
Any lingering clouds should thin through the day today as the cold front associated with aforementioned area of low pressure sags further south and high pressure continues to build in from the north.

Thursday will feature more sun with only patchy high clouds expected with continued dry weather. Today & Thursday will be very similar temperature wise, with highs in the low to mid 70s today, and a couple degrees warmer Thursday. Lows will be in the upper 40s to mid 50s both nights. RH values will fall into the 30% range each afternoon, but the lack of wind and increasing green-up should prevent any widespread fire weather concerns.

As low pressure moves toward the upper Great Lakes Thu night, the frontal zone to the south and west will begin lifting north as a warm front. While clouds may start to increase, any rain will likely hold off until Fri afternoon/evening. However, not looking at any widespread rain until the cold front moves through Sat.

LONG TERM /SATURDAY THROUGH TUESDAY/
Sharp cold front associated with a southern Ontario and northern New England upper low will cross the area around 18Z Sat with showers and possible t-storms impacting the fcst area during the morning into early afternoon. High pressure builds over the area Sat night through Monday morning supporting cooler temperatures and fair weather conditions. High pressure will move offshore Monday afternoon with srly flow developing and returning moisture into the area. Another cold front will cross the area during the middle of next week bringing the next chance of showers for Wed night and Thu of next week.

AVIATION /13Z WEDNESDAY THROUGH SUNDAY/
VFR conditions are likely through Thursday as high pressure builds nearby. Winds become light out of the E/NE today, before becoming more SE Thursday. As a warm front approaches, overrunning moisture could result in some sub-VFR ceilings by late Thu night into Friday. Any restrictions associated with rain showers likely wait til late Friday.

Sub-VFR conditions likely continue into Saturday as a cold front approaches and moves through the terminals. Southerly winds ahead of the front shift to west/northwesterly in the wake of the frontal passage. Showers and thunderstorms are possible Saturday. VFR conditions return Sun.

MARINE
Monitoring the potential for northerly channeling down the bay in the predawn as low pressure moves off the coast. May best be handled with an MWS if it materializes given anticipated short duration.

Otherwise, high pressure will build across the area today and Thursday, resulting in light winds. NE to E winds Wed will become SE by Thursday.

SCA criteria winds are possible on Fri due to southerly channeling ahead of a cold front. Showers and thunderstorms impact the waters Fri and Sat with winds shifting to northwesterly in the wake of the front. Small Craft Advisories are likely on Sat.
