FitzsimmonsWhat 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 Jul 29, 4:16 PM EDT, 14 minutes earlier.
Area forecast discussion, Jul 29, 4:16 PM EDT, 14 minutes before
Area Forecast Discussion National Weather Service Mount Holly NJ 416 PM EDT Thu Jul 29 2021 .SYNOPSIS... A warm front will lift north of the area this evening before a cold front moves across the area tonight. High pressure located across the Mid West on Friday will build toward the east coast on Saturday. Another cold front is forecast to move across the area later Sunday into Sunday night. High pressure may briefly affect the area before an area of low pressure lifts north offshore of the east coast on Tuesday. The frontal boundary to our south may lift northward and affect the area for the middle to end of next week. && .NEAR TERM /UNTIL 6 AM FRIDAY MORNING/... A Tornado Watch is in effect for the entire forecast area through 9 PM tonight. The warm front continues to push northward this afternoon, as we have seen some destabilization occur fairly quickly behind it. The remnant MCV that moved through the Great Lakes is pushing into eastern Pennsylvania and should move off of the New Jersey coast this evening. Most of the region remains in a slight or enhanced risk for severe weather, as issued by the SPC. The threats are damaging winds, large hail, and an isolated tornado. The primary threat time will be this afternoon into evening. While there are clouds clearly seen on visible satellite across the area, there are many breaks occurring with peeks of sun coming through. This is enhancing our instability and as a result confidence has grown that we will see convection develop and move through our area this afternoon and evening. Some early showers and thunderstorms have started to pop up across Delmarva and New Jersey with the main line of storms off to the west in central PA. There is still support for effective bulk shear values of ~45 kts, which will be more than sufficient to support rotating updrafts. Some upscale growth is forecast as multiple cold pools start to be deposited and merge. While areas to the north may see less of the action this afternoon, there is still the possibility for some strong to severe storms in those areas. To the south and east, we have seen much more clearing and temps have risen appreciably in response. Dew points have climbed into the upper 60s to lower 70s, and heavy down pours remain another threat today though the storms should have sufficient motion so flash flooding is not as high on the threat list at this time. However, there is potential that along the frontal boundary we could see some back building so we will need to monitor those areas for flooding concerns. As the storms clear the coast, surface low pressure will be located near the NY/Canada border and be dragging a surface cold front through the area. Winds will slowly turn from the northwest through the night with skies slowly clearing from the west. && .SHORT TERM /6 AM FRIDAY MORNING THROUGH FRIDAY NIGHT/... Surface low pressure moves off to the northeast with its attendant cold front offshore by Friday morning. With the front offshore, the flow across the region will turn to the west and settle out of the northwest. Winds may become gusty through the afternoon, with gusts around 25 mph or so. Skies will be relatively clear through the day and with dew points dropping down into the 50s (potentially 40s in spots) it will feel nice and dry and pretty comfortable for late July. The cooler air being drawn into our region will be slightly below normal with highs into the 70s through the southern Poconos, northwest New Jersey and the Lehigh Valley and low to mid 80s through the rest of the region. Depending on how far offshore the front moves, we could see some temps remaining in the upper 80s for a while across southern Delaware and nearby eastern Maryland. Friday night will be cold when compared to what we typically see in late July. The clear skies will help with radiative cooling and with the winds dropping off overnight, we should see things drop off decently overnight. Overnight lows will be a chilly upper 40s to low 50s across the northern zones through the Lehigh Valley and into portions of central New Jersey. Around the urban corridor and through Delaware, Maryland, and southern New Jersey, temperatures will be in the mid 50s to lower 60s. && .LONG TERM /SATURDAY THROUGH THURSDAY/... The first half of the weekend is expected to be quiet, before the potential for unsettle weather returns for the end of the weekend through much of next week. On Saturday, high pressure to the west will control the weather, providing a dry forecast through Saturday night. Below normal temperatures are expected through Saturday night as well. On Sunday, active weather could once again return to the forecast. An area of low pressure is forecast to move across southeast Canada and bring a frontal boundary/surface trough across the east coast Sunday into Sunday night. Meanwhile, an area o flow pressure may form along the frontal boundary to our south and move to the northeast offshore of the Mid Atlantic coast. There will be a chance of showers and thunderstorms through the day Sunday, most likely associated with the approaching frontal boundary coming from the west. The low off the coast may remain far enough offshore to not bring any impacts to the area. On Monday, our area will be in between the departing system from the weekend, and another potential coastal low that is expected Tuesday. Therefore dry weather is expected on Monday. However, on Tuesday, another coastal low is forecast to develop to our south and may end up inching close enough to the coast to bring a chance of showers and thunderstorms to the area. As we go through the second half of the week, unsettled weather is possible to continue for Wednesday and Thursday as the front to the south may begin moving back northward and into the area while a couple of low pressure systems may develop and move near the area as well. Temperatures for the long term period are expected to be near or slightly below normal for the weekend into much of next week. && .AVIATION /20Z THURSDAY THROUGH TUESDAY/... The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas. Tonight...Showers and thunderstorms will move the terminals from west to east this afternoon, ending between 22Z-03Z. Conditions will drop to MVFR/IFR in and around any storms. Winds may gust in excess of 30 knots in and near thunderstorms. Conditions are expected to be MVFR for a period of time behind the storms before returning to VFR by late tonight. South to southwest winds around 10 to 15 knots, becoming northwest around 5 to 10 knots overnight. Moderate confidence overall with low confidence in thunderstorm timing. Friday...Mainly VFR. Northwest winds around 10 to 15 knots with gusts up to 25 knots possible in the afternoon. High confidence. Outlook... Saturday-Saturday night...VFR. Northwest winds 5-10 mph during the day, light and variable overnight. Sunday...Mostly VFR. Chance of showers and thunderstorms which may temporarily lead to lower conditions. Southwest winds 5-10 knots, gusts 15-20 knots possible. Sunday night...Chance for conditions to lower below VFR overnight. South winds early, becoming northwest overnight. Monday-Monday night...Mostly VFR expected. Northwest winds 5-10 knots during the day, light and variable overnight. Tuesday-Tuesday night...Mostly VFR. Chance of showers and thunderstorms which may temporarily lead to lower conditions. Northwest winds 5-10 knots during the day, light and variable overnight. && .MARINE... SCA remain up for the ocean waters through midnight tonight. Winds will gusts around 25 knots on the ocean in response to a tightening pressure gradient. Winds will start to drop off tonight. Seas around 3 to 4 feet. Mainly sub-SCA conditions are expected for Friday. Northwest winds around 10 to 15 knots with gusts around 20 knots. Seas will remain around 3 to 4 feet. A few gusts may near 25 knots late afternoon into Friday night in the strong northwest flow, especially in the coastal waters off of northern and central New Jersey. However, will hold off on issuing any new SCA's at this time until the current SCA has expired. Outlook... Saturday-Tuesday...Conditions are expected to remain below Small Craft Advisory levels through the period. Rip Currents... Winds will increase to 15 to 20 kts today with gusts at SCA criteria. There will be an onshore component for the NJ coast today as winds veer from the south. Given the above, and the 8 second period forecast, the rip risk for Coastal Cape May and Coastal Atlantic will be MODERATE today. The rest of the beaches will be kept at LOW given the orientation of the coastline relative to the wind direction. Winds shift offshore for Friday, so the rip risk for Friday will be LOW. && .PHI WATCHES/WARNINGS/ADVISORIES... PA...None. NJ...None. DE...None. MD...None. MARINE...Small Craft Advisory until midnight EDT tonight for ANZ450>455. && Synopsis...Robertson Near Term...Meola Short Term...Meola Long Term...Robertson Aviation...Meola/Robertson Marine...Meola/Robertson
