What forecasters said that day
The local office's own words before this flash flood watch 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 flash flood watch went out at Jun 16, 9:21 PM EDT, 6 hours 30 minutes earlier.
Area forecast discussion, Jun 16, 9:21 PM EDT, 6 hours 30 minutes before
Area Forecast Discussion National Weather Service Mount Holly NJ 921 PM EDT Sun Jun 16 2019 .SYNOPSIS... A quasi-stationary frontal boundary will remain in place across the northern Mid-Atlantic through much of the upcoming work week. Several waves of low pressure are expected to develop along this boundary and pass across the region leading to several rounds of showers and thunderstorms through late this week. A stronger system and frontal boundary will pass through the region late Thursday into early Friday resulting in quieter weather in its wake. && .NEAR TERM /UNTIL 6 AM MONDAY MORNING/... The showers and thunderstorms that fired up over Lancaster and York counties this afternoon are now off the coast. Scattered showers and thunderstorms finally initiated across the Baltimore area a short time ago and are now moving across the Delmarva into southern NJ. The line of showers running from Scranton to Pittsburgh are in closer proximity to the front itself, but are slowly decaying. The larger area of showers and thunderstorms across the lower Ohio Valley are not modeled to make it here. For the evening update, I took out the severe threat mention and took out the likely PoPs. For the remainder of the overnight, chance or slight chance PoPs remain. With winds going light, fog is more likely overnight where it rains. Previous discussion... We still haven't seen much redevelopment with what remains of the earlier MCS now over northern VA/central MD. That will be key to potential for thunderstorms this afternoon and evening. The front has inched ever so slowly south, and is now across northern PA, but still north and west of our region. Of note, most high res guidance has had a warm bias over the last several hours. Additionally, conditions further west don't look much different than in our area. However, we do still have a few hours left of diurnal heating which could mean that by the time the trough reaches our area, there will be more opportunity for showers and thunderstorms to develop. Therefore, I'm not ready to write off the potential yet this afternoon and evening. If we see convective initiation, there remains a risk for severe storms, primarily for damaging winds. Instability is limited (especially if this trend continues with guidance being too warm), but it may be sufficient enough with bulk shear values of 20 to 30 kt to result in limited coverage of severe storms. Overnight, the front is expected to continue to slip south into our region. As it does so, fog may develop, especially in the vicinity of the front. However, where exactly this front will end up by morning is still quite uncertain. Some models have it almost entirely south of Delaware by morning, though the majority of guidance appears to keep it near ILG and PHL. Given the progression we've seen so far today, I'm inclined to believe the further north solution will be correct. && .SHORT TERM /6 AM MONDAY MORNING THROUGH MONDAY NIGHT/... Another short wave trough will be riding along the front (which should once again be stalled). There is some uncertainty with how much instability we will have if we see as persistent low clouds and fog as what has occurred today in the vicinity of the front in NY (and as mentioned above, where this front will stall is still very uncertain). None the less, at this point it looks like another round of showers and thunderstorms will be possible, mostly late afternoon through the evening. As for the risk of severe storms, the main threat will be south of the front, and will be mostly a wind and hail threat. Shear may be more limited tomorrow than today, especially south of the front where the highest instability will be. The main threat tomorrow however, looks like it will be a heavy rain and flooding threat. Along and south of the front, there could be several risk factors, including very high precipitable water values (above 2 inches) and a very deep warm cloud layer. There is potential, especially Monday evening, for training storms, since the mid and upper level flow will be almost parallel to the front. Held off on issuing a flash flood watch at this time given the uncertainty with where the front will be, and thus where the threat area will be. If the front stalls near ILG, then the main threat area will be over northern Delmarva and far southern NJ (Salem, Cumberland, Atlantic, and Cape May). && .LONG TERM /TUESDAY THROUGH SUNDAY/... Summary: Long term forecast was updated using the latest national blended guidance. No significant changes were made to the previously issued long term forecast. The medium range continues to look quite unsettled, with chances of strong convection and heavy rain multiple times through late Thursday. A stronger system and frontal boundary will clear the area by early Friday leading to at least a brief lull in the active and wet week ahead. Global guidance indicates much of the eastern CONUS will remain in quasi-zonal upper to mid-level flow through late Thursday with numerous shortwave troughs and perturbations propagating through the flow during that time. At the surface, a quasi-stationary frontal boundary will remain in place across the region generally near the northern part of the forecast area. This pattern will result in a few rounds of showers and storms through late Thursday. As typical with this type of pattern, global scale guidance does not handle the details of convective evolution of timing very well, neither do mesoscale model beyond about 24-36 hours. Therefore the timing, evolution, and strength of showers and storms remains uncertain through much of the long term at this time. That being said, a few rounds of convection during this time may bring the potential for strong to severe thunderstorm and/or flash flooding. The details on the evolution of the convection will be better resolved in the short/near term (24-48 hours) time period. By early Friday, a stronger system looks to push through the region ahead of a higher amplitude medium wave trough. This will bring an end to the active period we have ahead of us this week. Some chances for showers and/or storms appear to return into the weekend. As previously mentioned, most of the area will be in the vicinity of a weak frontal boundary with southerly to westerly flow along and south of it. This will result in dewpoints in the upper 60s to around 70 degrees and temps roughly within a few degrees of normal. Persistent, although intermittent, cloud cover will moderate temps such that night time lows will be relatively warm (mostly upper 60s) and daytime highs relatively cool (mostly low 80s) compared to climatological normals. Honestly not too bad considering the time of year! && .AVIATION /01Z MONDAY THROUGH FRIDAY/... The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas. Rest of this afternoon...Mostly VFR conditions should continue. However, there remains a chance for showers and thunderstorms. The highest risk of TSRA is mostly from KRDG and KPNE southward. Southwesterly winds 10 to 15 kt should continue through the afternoon, though gusty and erratic winds are possible in the vicinity of thunderstorms this afternoon and evening. Tonight...Chances for storms continue for the first part of the evening. Additional showers and possibly a thunderstorm or two could develop behind the main line of convection, but coverage would likely be limited. After 06Z, once storms dissipate, there is a chance for localized BR to develop, especially for any areas that receive heavy rain this evening. Confidence in this occuring is quite low. Southwest winds near/below 10 kts becoming light and variable overnight. Monday...starting VFR. A chance for showers and thunderstorms returns after 18Z. MVFR and even IFR conditions will be possible with the afternoon showers and storms. Winds will be light and variable in the morning, becoming southwesterly 5 to 10 kt by the afternoon. Outlook... Monday night...IFR conditions with showers and thunderstorms possible especially through 06Z. Depending on if any terminals receive heavy rain, localized BR may again develop after 06Z. Winds are expected to become light and variable overnight. Tuesday through Thursday night...An unsettled and stormy pattern is expected through late week. Mainly VFR conditions are expected outside any showers and storms, however showers and storms may briefly lower conditions to sub-VFR at times. Winds generally from the west or south around 5-10 kts. High confidence on the overall pattern, but low confidence on timing of precipitation. && .MARINE... For the evening update, the SCA will be cancelled around 930 for the southern waters. The SCA was extended for another couple hours across the northern waters. Previous discussion... Seas will gradually diminish through the evening. The Small Craft Advisory will continue on the coastal waters through 10 PM EDT. Once seas drop below 5 ft, winds and seas should stay below SCA criteria tonight and tomorrow. However, strong winds will be possible in the vicinity of any thunderstorms both this evening and again Monday afternoon and evening. Outlook... Tuesday through Thursday night...Sub-advisory conditions are expected through the outlook period, however seas and winds may be high in and around scattered showers and thunderstorms through the period. Seas may build to 4-5 feet Thursday night. && .PHI WATCHES/WARNINGS/ADVISORIES... PA...None. NJ...None. DE...None. MD...None. MARINE...Small Craft Advisory until midnight EDT tonight for ANZ450>453. && Synopsis...Staarmann Near Term...Johnson/Kruzdlo Short Term...Johnson Long Term...Staarmann Aviation...Johnson/Staarmann Marine...Johnson/Kruzdlo/Staarmann
