The local office's own words before this special weather statement went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Philadelphia/Mount Holly wrote its last area forecast discussion before this special weather statement went out at Sep 4, 6:40 PM EDT, 3 hours 16 minutes earlier.
Area forecast discussion, Sep 4, 6:40 PM EDT, 3 hours 16 minutes before
Area Forecast Discussion National Weather Service Mount Holly NJ 640 PM EDT Wed Sep 4 2019 .SYNOPSIS... A cold front will cross the region tonight before stalling to our south. High pressure builds toward the Mid-Atlantic on Thursday. Hurricane Dorian will cross eastern North Carolina on Friday before moving quickly to the northeast and past our area Friday night. A weak cold front will move through the region later Saturday, followed by a return to high pressure for Sunday into the new week. && .NEAR TERM /UNTIL 6 AM THURSDAY MORNING/... 630 PM...Some storms developing near I-95 corridor and some of these could still be strong to severe early this evening as the front moves south. However not much developed farther north in the area that was in the Watch so this has been cancelled. The cold front will move SE into the Delaware Valley around dusk then offshore NJ/DE by 10PM or so. Drier and cooler air will arrive behind the front. Clouds will decrease late and with the dry air, not much in the way of fog is expected overnight. Low will drop into the low/mid 50s N/W and low/mid 60s across srn NJ and Delmarva. Winds will shift to NW this evening behind the front then the go N or NE towards dawn. && .SHORT TERM /6 AM THURSDAY MORNING THROUGH 6 PM THURSDAY/... The cold front will be SE of the area Thursday morning while weak high pressure builds to the north. Hurricane Dorian will be moving slowly N/NE along the S Carolina coast. The (thicker/lower) clouds in advance of Dorian will be arriving across Delmarva during the morning and into NJ/ern PA by afternoon. A slowly increasing NE winds will also our region. A couple showers may arrive across srn NJ and Delmarva late, so some chc pops are in the fcst for these areas attm. It will be cool on Thursday with highs only in the low/mid 70s. Winds will be mostly northeast at 10 to 15 mph, but gusts around 25 mph are expected along the DE/NJ coastal areas. && .LONG TERM /THURSDAY NIGHT THROUGH WEDNESDAY/... The main feature of this period is what will occur with Hurricane Dorian as it makes it way up the Mid-Atlantic coastline. Current NHC tracks Dorian through eastern North Carolina on Friday, crossing Hatteras and then pushing up the Mid-Atlantic coast on Friday and continuing into the North Atlantic waters on Saturday. Based on the current forecast track, we would likely start to see some of Dorian's rain arrive Thursday night with the bulk of the impacts not felt until Friday. The majority of the impacts will be along the immediate coast due to their proximity to the storm and the further inland you go there will be less impacts. Rainfall will be heavy at times and around 1 to 3 inches of rain may fall, with the heaviest across southern Delaware and up along the New Jersey coast. Winds will ramp up quickly, especially along the coast and winds of 30 to 40 mph with gusts around 50 mph are possible, again mainly right along the coast. The main takeaway with Dorian is keep an eye on the forecast and monitor the track of the storm. Impacts are closely tied to just where the storm goes so if it stays further or closer to our area, the impacts will change. && .AVIATION /00Z THURSDAY THROUGH MONDAY/... The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas. This evening...Scattered thunderstorms will continue to move across the region with MVFR and psbl IFR with any tstm. Winds will be mostly S or SW this evening and then turn W or NW once the tstms/showers move thru. Improving conditions late. Tonight...VFR returning to the terminals as tstms move away. NW winds will bring in drier air overnight. After midnight, winds will become N then NE. High clouds increasing across Delmarva and srn NJ towards dawn. Thursday...VFR expected. Increasing clouds from SE to NW thru the late morning and afternoon. A few showers are possible late across Delmarva and srn NJ. I have not included them in the 18Z tafs however, since chance is low. Outlook... Thursday night and Friday...MVFR ceilings along with some possible rain developing for a time mainly at MIV and ACY especially on Friday, otherwise VFR ceilings. Northeast winds 5-15 knots Thursday, increasing to 10-20 knots Friday with higher gusts especially at MIV and ACY. Winds becoming north to northwest Friday night and diminishing. Saturday and Sunday...VFR. Northwest winds 10 knots or less Saturday, then light west-northwest Sunday. && .MARINE... Winds and seas slowly increasing out ahead of a cold front which will cross the waters early tonight. Winds and seas will locally be higher with the tstms, but overall conditions will remain below SCA tonight. Seas on the ocean will be 3 to 4 ft. SMW may be issued for tstms this evening. Winds will shift from SW before the front to NW behind it. Later tonight, winds will become N. Thursday...Sub-SCA, but winds will increase from the N then NE thru the afternoon. Showers will arrive across the srn NJ and DE waters late during the afternoon. Seas mostly 3 to 4 ft on the ocean. Outlook... Thursday night through Friday...Strong northeast winds developing, especially Friday, with dangerous seas. Wind gusts of 35-45 knots are probable, with these peaking during Friday. Gusts in excess of 50 knots are possible, mainly across the Delaware and extreme southern New Jersey coastal waters. The winds become north and diminish during Friday night. Saturday and Sunday...Northwest winds rapidly diminish Saturday, then becoming southwesterly at night and Sunday. Rip Currents... We are expecting a somewhat chaotic swell pattern for today, with swells arriving from the east, southeast and south. As a result, we will carry a moderate risk for the development of dangerous rip currents. Otherwise, there will be a southerly wind at the beaches increasing around 15 MPH with breaking waves around 3 feet. At least a moderate risk for the development of dangerous rip currents Thursday, then a high risk is anticipated for Friday as the center of Hurricane Dorian passes by our region well offshore. The large swells and gusty onshore winds will result in dangerous surf and rip currents. The conditions are expected to improve over the weekend. && .TIDES/COASTAL FLOODING... A prolonged onshore flow is expected from Thursday into Friday night. As a result, water will build up along the coast. We may experience some minor tidal flooding along the coasts of Delaware and New Jersey Friday afternoon. Depending on the forward speed of Dorian, we will need to keep an eye on Friday night's high tide and possibly Saturday afternoon's high tide for additional minor flooding. && .PHI WATCHES/WARNINGS/ADVISORIES...

MARINE...None. && Synopsis...Meola Near Term...Fitzsimmons/O'Hara Short Term...O'Hara Long Term...Gorse/Meola Aviation...Gorse/Iovino Marine...Gorse/Iovino/Meola Tides/Coastal Flooding...
