Synopsis for the tidal potomac and md portion of the chesapeake bay..
high pressure will remain near the waters through Wednesday before pushing offshore Thursday. A strong cold front will cross the waters Friday into Saturday. High pressure returns Sunday with several weak pieces of energy crossing the waters early next week. Small craft advisories may be needed late Friday, and will likely be needed behind the front on Saturday.

Area Forecast Discussion National Weather Service Mount Holly NJ 315 AM EDT Wed Oct 4 2023
SYNOPSIS
High pressure will become more centered to our east and northeast through tonight, however it will continue to extend across our region. The high weakens and shifts more to our northeast Wednesday into Thursday. A strong cold front moves through on Saturday, which brings a colder and much drier air mass into our region over the weekend through early next week.
NEAR TERM /THROUGH TONIGHT/
A clear sky and light wind allowed areas of fog to develop during the night, mainly in the valleys of eastern Pennsylvania and northern New Jersey, and in the Pine Barrens of southern New Jersey.
The fog is expected to lift and dissipate during the mid morning hours.
High pressure extended from the southeastern states up into New England early this morning. The air mass will build slowly eastward today and tonight, bringing continued dry weather to our region.
A light southerly wind is anticipated to develop for this afternoon, with a light and variable wind returning for tonight. Maximum temperatures this afternoon will again be well above normal, with highs mostly from the upper 70s into the middle 80s. Tonight's lows should favor the 50s with some fog expected.
SHORT TERM /THURSDAY THROUGH FRIDAY NIGHT/
Temperatures still on the mild side, however a downward trend begins.
Despite high pressure becoming more and more centered to our northeast, it will still remain in control of our weather through Thursday. While some high clouds may start to arrive Thursday morning, conditions look favorable once again for early morning patchy fog especially in parts of eastern Pennsylvania and northern New Jersey. We will begin to see some signs of change on Thursday, as there should be at least some increase in high clouds by the end of the day. Overall though, expect one more mild and dry day with highs mostly in the mid to upper 70s. More of an east to east- southeast wind though will keep in cooler along the coast.
Thicker clouds will start to overspread our region Thursday night into Friday morning. The low-level flow will be from the east to southeast, and this will start to increase the lower level moisture with time. Some stratus may develop later Thursday night and Friday morning as moisture advection teams up with some increase in the warm air advection. This could also result in a few showers or even some drizzle assuming the stratus forms. Confidence remains low on how this plays out therefore kept the PoPs through midday Friday on the low side. Guidance generally agrees that a weak shortwave will be approaching our area from the west-southwest Friday afternoon, well in advance of the main upper-level trough and associated surface cold front tracking across the Great Lakes and the Ohio Valley. Deeper moisture and forcing as well as instability looks like it will be limited at that time, so while some thunder cannot be completely ruled out, opted to keep a mention out for now.
Conditions will still be mild and even more humid with highs in the 70s. The showers should then start to increase some Friday night, especially across the western areas.
LONG TERM /SATURDAY THROUGH TUESDAY/
Summary...Turning much cooler to colder and eventually much drier over the weekend into early next week. Showers Saturday as a strong cold front moves through, then mainly dry.
Synoptic Overview...An upper-level trough looks to close off as it shifts across the Great Lakes and vicinity Saturday, then remains across the East Sunday through early next week. A strong cold front crosses our area Saturday, then cyclonic flow and much cooler to colder air dominates through early next week.
For Saturday...A sharp upper-level trough is forecast to close off across the Great Lakes Saturday as it gradually shifts eastward. A strong shortwave is forecast to round its base across the upper Ohio Valley and the eastern Great Lakes. As surface low pressure occludes across the eastern Great Lakes, a trailing cold front is forecast to cross our area during Saturday. Forcing for ascent with the cold front and trough aloft will maintain showers. The strongest forcing may remain to our west given the main trough hanging back well to our west until Saturday evening. Isolated thunder cannot be ruled out, especially across the northern areas as some enhancement to a band of showers may occur in the afternoon as the main trough starts to arrive. It is there were some guidance shows an axis of weak instability potentially becoming more focused. Given that the instability looks to be on the limited side and the strongest flow hangs back to our west, severe thunderstorms are not anticipated.
Temperatures will depend on how quickly the front clears the region, but may feature highs occurring earlier in the day. Southerly winds will increase some ahead of the cold front, then quickly become west to northwest in the wake of the cold front and increase more as strong cold air advection takes over. Much cooler to colder air and tumbling dew points will overspread the area in the wake of the cold front, and any showers should be ending Saturday night.
For Sunday through Tuesday...An upper-level trough/closed low is forecast to dominate the East. Cyclonic flow along with cold air aloft may result in stratocumulus developing overhead or spreading in from the west at least during Sunday and Monday. A tightened pressure gradient coupled with deeper mixing within the boundary layer will result in a chilly breeze which will also be gusty for much of this time frame. The flow however may start to back to the west-southwest Monday and Tuesday as the closed low may shift westward some across the Great Lakes region. There should be some lake response, however much of those showers should remain closer to the eastern Great Lakes especially as the flow backs more with time.
Still cannot rule out some brief showers or sprinkles Sunday into Monday manly for the Pocono region. High temperatures in the 50s to low 60s Sunday and Monday (some 40s in the Poconos), then a little milder Tuesday as the air mass starts to slightly warm aloft.
Widespread 40s at night are forecast, with even some upper 30s mainly in the Poconos.
AVIATION /07Z WEDNESDAY THROUGH SUNDAY/
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas...
Today...Early morning restrictions are expected due to fog.
Otherwise, VFR under a mostly clear sky from late this morning into this afternoon. Variable wind 5 knots or less, becoming southerly 4 to 8 knots in the afternoon. Medium confidence in the extent of the morning fog, otherwise high confidence in VFR conditions for the late morning and afternoon.
Tonight...VFR under a mostly clear sky. Areas of fog may impact some of our TAF sites after 06Z. Variable wind 5 knots or less. Medium to high confidence.
Outlook...
Thursday...VFR. Some low clouds may develop however late at night.
Light and variable winds becoming southeasterly 5-10 knots. Low confidence regarding low cloud development.
Friday...A period of MVFR, possibly IFR, with a chance for some showers during the day and especially at night. Southeast winds 5-10 knots. Low confidence.
Saturday...MVFR/IFR conditions with showers. Southwest winds 5-10 knots becoming west to northwest 10-15 knots and possibly gusty. Low confidence.
Sunday...Mainly VFR. Westerly winds 10-20 knots with gusts to around 25 knots. The winds should diminish some at night. Moderate confidence.
MARINE
A light and variable wind this morning is forecast to become south to southeast 5 to 10 knots this afternoon. The wind is expected to back toward the east tonight. Wave heights on our ocean waters are expected to be 2 to 3 feet, with waves on Delaware Bay at 2 feet or less.
Outlook...
Thursday...The conditions are anticipated to be below Small Craft Advisory criteria.
Friday and Saturday...Small Craft Advisory probable, mainly due to seas on the ocean zones that may build to 5 feet Friday night then to 5-7 feet Saturday. Southeast to southwest winds will increase some, however the strongest winds (possibly gusting to 25-30 knots)
should occur Saturday with a wind shift from the west and northwest in the wake of a strong cold front.
Sunday...Small Craft Advisory conditions probable due to gusty winds and elevated seas.
