NEAR TERM /THROUGH TODAY/
Starting to see another round of fog/stratus develop as the high off to the northeast continues to foster an onshore flow, reinforcing moisture in the low-levels. With mostly clear skies expected yet again, some radiational fog is expected, some of which could be dense. The one potential wrinkle is that winds within the low-levels look to be a touch stronger compared to last night, which could keep things mixed just enough to prevent the widespread development of dense fog. As a result, will hold off on issuing any advisories. If an advisory is needed, thinking it would be for the NJ coastal plain, similar to where it was for last night. Lows will drop into the mid to upper 50s and low 60s.

For Friday, the fog/stratus mixes out by mid to late morning and another nice day is expected to close out the week. Expect mostly sunny skies and temperatures in the upper 70s and low 80s.

SHORT TERM /TONIGHT THROUGH SUNDAY/
Upper-level ridge centered over the Great Lakes region Friday night meanders just bit to the southeast with time through the term. Generally speaking, the upper-level pattern looks to remains fairly stagnant. At the surface level, high pressure centered to our north/northeast Friday night will slide to the south with time. Overall, surface high pressure maintains influence over the region through the term.

Not a whole lot to discuss weather wise given the pattern. No precipitation is expected; no PoPs included in the forecast.
Mainly clear to, at times, partly cloudy skies through the term.
Patchy fog is likely during the overnight periods with the stagnant pattern and some light onshore flow.

LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/
A rather complex and uncertain long term forecast is on the horizon. The ensembles indicate an upper-level pattern which will remain fairly stagnant through the term; main upper-level features in play not changing much in the grand scheme of things. Forecaster confidence is low overall; multiple factors will be in play including upper-level ridge erosion and surface low pressure development.

At the surface level, fair confidence remains that surface high pressure will maintain influence over the region into Tuesday as it remains centered over or offshore of our region. However, a stationary boundary offshore of the southeastern CONUS may spawn a surface cyclone sometime Sunday into Tuesday; a scenario which will need to be watched carefully. A frontal boundary over this location this time of year should never be trusted, as subtropical or tropical development could be in the cards.
Guidance suggests the surface low pressure which may spawn should then want to move north/northwestwards with time, possibility bringing us precipitation potential later Tuesday into the rest of the long term as it moves forwards.

We will just need to watch carefully as the forecast evolves.
Stuck with NBM for this forecast given the situation. Dry forecast for Monday with PoPs approaching the south/southwest later Tuesday onwards.

AVIATION /06Z FRIDAY THROUGH TUESDAY/
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas.

Tonight...VFR to start. Fog and low stratus at most terminals between 07-09Z though confidence remains low. However, thinking between low stratus and fog that does develop, conditions will drop to IFR/LIFR. Winds light and variable. Moderate confidence in timing and extent of restrictions.

Friday...IFR/LIFR to start with fog/low stratus. Conditions lift to VFR by 14-15Z with a few afternoon clouds. Winds generally out of the east around 5-10 kt. Moderate confidence overall.

Outlook...

Friday night through Tuesday...Mainly VFR with no significant weather expected. Patchy to areal fog possible at night may cause temporary visibility/ceiling restrictions.

MARINE
No marine headlines expected through tonight, though some fog potentially develops in the upper Delaware Bay and nearshore waters, inlets, and bays. Will keep an eye on observations to see if a Marine Dense Fog Advisory is needed. Winds generally out of the east around 5-10 kt with seas 2 to 3 feet.

Outlook...

Friday night through Saturday night...No marine headlines anticipated.

Sunday through Tuesday...SCA flag possible. Seas may grow to around 5 feet Sunday before possibly becoming 5-7 feet Monday/Tuesday.

Rip currents...

For both Friday and Saturday...East winds will develop at 10 to 15 mph. Breaking waves will average 2 to 3 feet with an 8 to 9 second period. With this onshore flow, there is a MODERATE risk for the development of dangerous and life threatening rip currents for both the Jersey Shore and the Delaware Beaches both days.
