MPSWhat forecasters said that day
The local office's own words before this severe thunderstorm warning 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 severe thunderstorm warning went out at Jun 29, 2:15 PM EDT, 54 minutes earlier.
Area forecast discussion, Jun 29, 2:15 PM EDT, 54 minutes before
Area Forecast Discussion National Weather Service Mount Holly NJ 215 PM EDT Sat Jun 29 2019 .SYNOPSIS... Low pressure tracking to our north today will pull a strong cold front across our area tonight with a secondary cold front moving through during the day on Sunday. High pressure builds in for Monday, then a weak disturbance and associated cold front moves through Tuesday before stalling just to our south Wednesday into Thursday. The front may potentially lift back to our north as a warm front Friday. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... Severe Thunderstorm Watch 462 now in effect for Kent county, Maryland and the rest of the eastern shore of Maryland and Kent and Sussex counties in Delaware and Sussex county. Severe Thunderstorm Watch 461 remains in effect. Thunderstorms are moving through the State College area. They are still a couple hours away from Berks county and several from the I95 corridor. Besides this more organized cluster of thunderstorms, additional thunderstorms could develop out ahead of it. Previous discussion... Off to a warm start this morning with 9 am temperatures around 80 degrees in many locales. Some low to mid 80s also being reported. Dewpoints were around 70 degrees...although they should mix lower this afternoon. The forecast is on track. SPC has kept much of the forecast area in slight risk with their morning update. The afternoon, the region will be in a highly forced and unstable atmosphere. Wind still looks to be the biggest threat with the thunderstorm's later today. In general, most organized convection should work west to east hitting our western zones mid to late afternoon, the I95 corridor late afternoon/early evening, and the beaches this evening. Previous discussion... A muggy start to the day, and the heat is expected to peak this afternoon as a cold front arrives. Severe thunderstorms are possible this afternoon and evening, roughly between 3 PM and 9 PM. An upper-level trough overspreads the Northeast later today, and surface low pressure tracks into New England. An associated strong cold front will be sliding southeastward across our area later this afternoon. Temperatures this afternoon peak into the lower to perhaps mid 90's for many places ahead of any convection, and this combined with humid conditions will result in peak heat indices into the mid to upper 90's especially in the I-95 urban corridor and also southern New Jersey and Delmarva. The urban I-95 corridor from Trenton to Philadelphia to Wilmington has lower heat index criteria (98-104F) through June 30th for a Heat Advisory. While there is some potential for the criteria to be met, it is not a certainty as some guidance suggests the surface dew points lower some this afternoon for some spots during peak heating. This is quite possible as the forecast soundings show a well-mixed boundary layer which could easily bring down some drier air. This will greatly impact the heat indices. As a result, held off on a Heat Advisory. Ahead of the front, the surface winds should turn more southwest to west- southwest and this will result in very warm air at most beaches especially the Delaware Beaches. Showers and thunderstorms are expected to accompany the cold front especially in the afternoon. Strong northwest flow aloft will occur with the upper-level trough nearing the Northeast. In addition, 30- 35 knots of flow in the mid levels will provide enough shear for storm organization. The forecast soundings show rather steep low- level lapse rates given a hot and well mixed boundary layer, and this results in an inverted-V signature. The soundings also show some drier air in the mid levels and this combined with the above along with water-loaded downdrafts can result in damaging winds. The instability should increase to near 2,000 J/KG of MLCAPE this afternoon, and with strong updrafts and high enough precipitable water frequent lightning will occur with the stronger cores. Marginally severe hail cannot be ruled out with the stronger storms. The hi-res guidance suggesting a line or broken line of storms developing along or just ahead of the cold front, however given the instability forecast more isolated convection should develop out ahead of it. The SPC continues a slight risk for severe thunderstorms for our entire area. A mention will continue in the Hazardous Weather Outlook. As with any convection, locally heavy rain can occur however storm motions are expected to be faster today which should lower the flash flood threat. && .SHORT TERM /6 PM THIS EVENING THROUGH 6 AM SUNDAY/... As a potent closed low moves into the Northeast overnight, surface low pressure will be exiting New England and its cold front will be settling southward and probably clears our area by daybreak Sunday. A line or broken line of thunderstorms, some potentially severe, should settle south and east of our area by late evening. The leading edge of more pronounced height falls arriving later this evening into the overnight may result in some redevelopment of showers or thunder behind the main line. A wind shift to the west and northwest occurs behind the cold front, however the surface flow should go light and much of the area is forecast to not see any significant lowering of the dew points tonight. This will result in a muggy night, and patchy fog cannot be ruled out as clouds thin out. && .LONG TERM /SUNDAY THROUGH FRIDAY/... Synoptic Overview: The extended period begins with a mid-lvl closed low diving southeastward through the area which kick off a second round of cold advection (mostly aloft). Upstream of this feature a SW-NE oriented ridge will prevail over the Central US, with an inverted trough residing south of the ridge over Texas. The central-US ridge axis relocates southeastward Monday into Tuesday, eventually centering itself over the southeastern US as broad troughing develops over the Western US. Various shortwaves moving over-top the eastern US ridge will likely impact the area starting Tuesday morning, with the flow generally becoming more zonal as the ridge axis flattens. A stalled boundary looks to set up near the area by the middle of next week with various convectively-enhanced shortwaves likely sparking diurnal convection over our area. Dailies: Sunday... As the mid-lvl trough axis passes just north of the area Sunday there will be another chance of showers and thunderstorms, with the highest chances over the northern part of the area closer to the greatest height falls. Despite increasing mid-lvl lapse rates as the mid-lvl cold pool passes overhead. don't think these storms will be particularly strong as the low-lvls will be drier than Saturday. High temperatures, Sunday will generally be in the 80s with breezy northwest winds and mid-lvl stratocumulus likely. Monday... High pressure briefly builds in SW of the area on Monday resulting in a quiet day. High temperatures will likely be similar to Sunday, with lighter winds and less clouds. Monday night/Tuesday... A shortwave will pass through the area Monday night into early Tuesday morning with a brief round of showers (and possibly a few thunderstorms) possible. Diurnal timing does not favor particularly strong storms and the system should be progressive with precipitation largely out of the area by Tuesday afternoon. Highs will be about 5 degrees warmer than Monday with a weak cold front pushing through later in the day. Wednesday-Friday... Wednesday will likely be dry and warm for most places, although there may be a chance of storms late in the day over Delmarva. Moisture will increase Thursday and this moisture combined with convectively-enhanced mid-lvl waves, and a nearby boundary will likely result in (at least) scattered convection Thursday/Friday (and potentially into the weekend). It looks like it will be fairly muggy with dewpoints around 70s and highs in the upper 80s to low 90s Thursday/Friday. && .AVIATION /18Z SATURDAY THROUGH THURSDAY/... The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas. Today...Local MVFR visibility early due to fog, otherwise VFR. Showers and thunderstorms arrive from northwest to southeast mainly this afternoon, especially after 18z, with MVFR/IFR conditions at times. Locally strong wind gusts are possible with some thunderstorms. Light and variable winds, becoming southwest to west- southwest 8-12 knots with local gusts up to 20 knots this afternoon. Tonight...Showers and thunderstorms early this evening, especially from the PHL area south and east with MVFR/IFR conditions for a time, then VFR overall. Local MVFR visibility cannot be ruled out for a time due to fog. West winds diminishing to near 5 knots, then becoming northwest or even locally light and variable. Outlook... Sunday...Mainly VFR with periods of mid-lvl (4-5k ft.) cloud cover. NW increasing to around 15 kts, with gusts 20-30kts. Sunday night...VFR with N/NW winds diminishing to 5-10 knots or less. Monday...VFR with light winds around 5 knots or less. Monday night - Tuesday...Mainly VFR. A shower or thunderstorm possible Monday night into Tuesday morning. West winds 5-10 knots becoming NW Tuesday. Tuesday night - Wednesday...Mainly VFR with light winds. && .MARINE... The conditions are expected to remain below Small Craft Advisory criteria through tonight. Southwesterly flow will increase some today with gusts to 20 knots possible, then diminish some tonight and become west to west-northwest. Some thunderstorms this afternoon and evening may produce local wind gusts of 34 knots or higher. Outlook... Sunday through Sunday night... Sub-SCA conditions expected, although winds near the shore may gust near 20-25kts Sunday afternoon/evening. Monday through Wednesday...Sub-SCA conditions expected with 3-4 seas Monday decreasing to 2-3 ft for Wednesday. Rip Currents... There is a low risk for the development of dangerous rip currents today with southwesterly winds 10-15 mph and waves (6-9 second period) in the surf zone around 2 feet. && .EQUIPMENT...
