Synopsis for the tidal potomac and md portion of the chesapeake bay -
high pressure will Wedge into the region for the end of the week, then move offshore over the weekend. Small craft advisories will likely be needed for portions of the waters both Friday and Saturday afternoons. Extensions may be needed due to southerly channeling Sunday into early next week. The next substantial front to cross the waters looks to arrive by Tuesday bringing renewed chances for showers and Thunderstorms.

AREA FORECAST DISCUSSION National Weather Service Wakefield VA 329 AM EDT Fri Apr 26 2024
SYNOPSIS
High pressure remains centered over New England today. High pressure slides offshore tonight, moving south into early next week with a ridge building over the area and temperatures well above normal through next week. An unsettled pattern sets up from Tuesday through late next week with daily chances for showers and storms.
NEAR TERM /THROUGH TONIGHT/
As of 325 AM EDT Friday...
Onshore flow has resulted in a stratus layer over NE NC and SW VA early this morning. While some redevelopment of this stratus layer is possible (mainly across NE NC), satellite trends suggest CAMs are overdoing sky cover with most areas currently under clear or partly cloudy skies along the coast. A mixture of cirrus and stratus remain inland early this morning with mostly cloudy to partly clear skies.
Temps as of 3 AM ranged from the upper 30s across interior portions of the MD Eastern Shore to low-mid 40s inland and upper 40s to around 50F along the coast. Morning lows a degree or two cooler.
Inland portions of the lower Maryland Eastern Shore should see clearing early this morning, and with decoupling winds, could see lows in the mid to upper 30s just before sunrise. This could result in patchy frost in typically cooler, more sheltered areas, but given the short window of time, don't expect widespread frost.
Clouds clear across E portions of the FA by this afternoon with at least scattered clouds (partly to mostly cloudy) lingering across W portions of the area through the day. Highs today in the mid-upper 60s inland and upper 50s along the coast. However, if clouds remain thick enough across W portions of the FA, temps will end up cooler than currently forecast (low-mid 60s). Otherwise, dry today with increasing clouds tonight and a slight chance of a brief, light shower across far W portions of the FA late tonight.
SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/
As of 325 AM EDT Friday...
A ridge builds over the area Sat, building into early next week with a warmup expected. However, the warm air will be delayed until Sun due to high pressure lingering off the New England coast on Sat allowing for one more day of cool, onshore flow. A weak piece of shortwave energy moves towards the area Sat and may provide just enough forcing (combined with isentropic ascent over the cooler airmass in place) for isolated, light showers across N portions of the FA. Models continue to be in disagreement with global models showing more coverage than hi-res models. As such, have kept PoPs at slight chance. Any showers taper off Sat evening with dry weather Sun as the high moves S and winds become SW. Highs in the lower 60s NE to around 70F SW Sat and upper 70s to lower 80s Sun. Lows in the lower 50s (upper 40s across the MD Eastern Shore) Sat night and upper 50s to around 60F Sun night.
LONG TERM /MONDAY THROUGH THURSDAY/
As of 325 PM EDT Thursday...
A high amplitude upper ridge axis will be in place over the eastern seaboard to begin the day on Saturday, with surface high pressure settling in just off the New England/northeast coast.
Meanwhile, a low pressure center will weaken as it drifts north across the upper midwest, sending a warm front across the Ohio River Valley and into the northern Mid-Atlantic Saturday morning. It may extend just far enough south to give us a slight chance of a rain shower, particularly across the northwest section of the CWA Elsewhere, expect a partly to mostly cloudy sky and slightly higher temperatures. Highs in the upper 60s to around 70 degrees inland, and in the low to mid 60s along the coast.
As high pressure builds offshore and settles in the western Atlantic late in the weekend through early next week, expect temperatures to quickly trend back up above normal through the period; highs jump into the 70s along the coast to low 80s inland on Sunday, with highs in the mid to upr 80s for most locations away from the immediate coast on Monday through Wednesday, before the upper ridge finally starts breaking down by the middle of next week. The next front approaches from the west Mon/Tue next week. Our next chance for showers and isolated storms will be possible with the frontal passage itself by Tuesday and Wednesday.
AVIATION /08Z FRIDAY THROUGH TUESDAY/
As of 140 AM EDT Friday...
Generally light and variable winds inland and NE winds 5-10 kt along the coast continue until sunrise with E/ENE winds increasing to 5-10 kt inland and 10-15 kt with some gusts to 20 kt after mid morning today. Given the onshore flow, a low stratus layer continues to linger across far S VA and mainly NE NC early this morning with IFR CIGs . Satellite trends suggest this cloud deck will continue to move SW with CAMs suggesting some redevelopment is possible near ECG. As such, have a TEMPO for IFR CIGs at ECG through 10z with prevailing MVFR conditions (~1000 ft CIGs ). Elsewhere, CIGs were generally VFR/MVFR with additional stratus possible at RIC/PHF/ORF through mid-late morning. Clouds push W of I-95 by this afternoon with VFR conditions returning under mostly sunny skies for the local terminals (partly cloudy at RIC).
Outlook: Dry/VFR conditions are expected at all terminals through the weekend.
MARINE
As of 245 AM EDT Friday...
Early this morning, high pressure remains centered over New England.
Winds are generally out of NE and range from 10 to 15 knots over the Chesapeake Bay/rivers and 15 to 20 knots over the coastal waters.
Winds will continue at similar speeds for much of the day today, before gradually diminishing later this evening into tonight. High pressure remains over the Northeast US or just offshore today through Saturday which will lead to continued onshore flow. As a result, seas remain elevated around or in excess of 5 feet today into tonight, before a gradual diminishing trend on Saturday. SCAs remain in effect for the coastal waters (and mouth of the bay)
through late this evening.
High pressure builds into the area this weekend before becoming suppressed to the south next week. Winds become southerly late Saturday night into Sunday, and then S to SW later Sunday into the middle of the week, generally ranging around 10 to 15 knots.
TIDES/COASTAL FLOODING
As of 845 PM EDT Thursday...
-Added a Coastal Flood statement for the middle peninsula and northern Neck to cover the upcoming high tide cycle. Water levels may potentially reach minor flood thresholds (or at least should be withing a few tenths) at Lewisetta, Windmill Pt, West Point, and Tappahannock.
A prolonged period of NE flow is expected to last into the weekend. Mainly nuisance flooding is possible across the lower bay, James River, VA Atlantic- facing beaches, eastern Currituck County, and Dorchester County with tonight's high tide. As such, Coastal Flood Statements are in effect for these locations. Locally minor flooding is possible along the S/W portion of the James River during this evening's high tide due to a favorable fetch of swell given NE winds. Smithfield will likely reach minor flood stage (potentially high-end minor) with Sewell's Point also showing the potential for reaching minor flood stage. As such, a Coastal Flood Advisory has been issued for these areas.
AKQ WATCHES/WARNINGS/ADVISORIES
MD...None.
NC...None.
VA...Coastal Flood Advisory until 4 AM EDT early this morning for VAZ089-093-095>097.
