Synopsis
High pressure remains over the area through Saturday. A cold front crosses the area Saturday night. Canadian high pressure builds across the local area Sunday.

Near Term - Through Tonight
As of 910am EDT Thursday... Much of the fog has burned off this morning. The region will remain under high pressure today, with a stationary front well to the NW of the area. Partly to mostly sunny this afternoon, with temps remaining warm. Highs this afternoon around 80 for most, and a bit cooler at the coast.

Short Term - Friday Through Sunday
As of 310am EDT Thursday... Fair this eve with fog/low clouds developing after midnite. A few CAMS are hinting at addntl moisture dvlpng across the Delmarva (light rain/drizzle) after midnite. Given the lack of agreement, kept a dry forecast attm with a Probability of Precipitation around 10%. Lows upper 50s-lwr 60s.

Morning low clouds/fog burn off Fri morning giving way to a pt sunny aftrn. Highs mid-upper 70s except lwr 70s at the beaches. Ditto, Fri nite with late nite fog/low clouds. Lows upper 50s-lwr 60s.

Low pressure tracks from the Gt Lakes region into southern Canada Sat. This results in pushing the trailing cold front east of the mts, crossing the local area late Sat aftrn/eve, pushing south into the Carolinas after midnite. Enough moisture/lift forecast for scattered showers to accompany the frontal passage Sat aftrn with enuf lingering moisture noted behind it for scattered showers to continue Sat nite (30-40 PoP). Not much Quantitative Precipitation Forecast with this event, generally and one tenth inch. Highs Sat mid-upper 70s. Lows Sat nite from near 50 north to near 60 se.

The front pushes into the deep south Sunday with Canadian high pressure building in from the north. Latest data suggests a dvlpng moist NE flow keeps the threat for widespread cloud coverage along with scattered showers Sunday morning, continuing into the aftrn hrs across the se. Cooler with highs around 60 north to around 70s south.

Long Term - Sunday Night Through Wednesday
As of 355pm EDT Wednesday... Monday and Tues will be warmer with highs ranging from the low 70s NW to the upper 70s to near 80F SE. Another cold front moves through Tues into Tues evening and will remain mostly dry with just a few isolated showers (25-30% PoPs). This cold front will drop the highs Wednesday into the low 60s NW and into the low 70s SE. Lows will range from the low 50s NW to the low 60s SE Sunday, and Tuesday nights. Lows will range from the upper 50s NW to the low to mid 60s SE on Monday night and from the upper 40s NW to the upper 50s SE on Wednesday night.

Marine
As of 310am EDT Thursday... SCAs (Small Craft Advisories) remain in effect for all of the coastal waters and the mouth of the Bay and these have been extended through Friday night (4th period) for now.

High pressure will remain in place over the region through Friday before finally breaking down as a cold front approaches the region on Saturday and crosses the area by early Sunday morning. With the area of high pressure in place for the next few days expect generally light onshore winds of 5 to 10 kts through Friday with a more SSW flow by Saturday morning ahead of the next cold front. Seas will be on the increase later today as swell from Hurricane Epsilon begins to arrive, then seas will remain elevated in the 5-6 ft range into the weekend. Expect that some of this energy will also creep into the lower Chesapeake Bay, and so will carry 3 to 4 ft waves for the mouth of the Bay; 1-2 ft elsewhere.

On Saturday, with the cold front moving through the waters will see a wind shift from SW to the N and NE Sat night into Sunday behind the front. Guidance is not showing much of a surge behind the front so not anticipating the need for SCAs (Small Craft Advisories) due to wind at this time. The offshore flow combined with Hurricane Epsilon being pushed away from the coast should begin to reduce the approaching swell and allow seas to start falling. However, still anticipating the need for SCAs (Small Craft Advisories) on the coastal waters due to elevated seas through Sunday.
