GorseWhat 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 3, 5:00 PM EDT, 2 hours 45 minutes earlier. Its key messages:
- 1. Dangerous heat and humidity will continue across the region through Saturday. All time record high temperatures could be challenged again today with widespread triple digit temperatures. 2. Daily chances for showers and storms will begin across the area today and continue into early next week. Some severe storms are possible each day through Sunday. There is a risk of flash flooding Sunday and Monday.
Area forecast discussion, Jul 3, 5:00 PM EDT, 2 hours 45 minutes before
Area Forecast Discussion
National Weather Service Mount Holly NJ
500 PM EDT Fri Jul 3 2026
.WHAT HAS CHANGED...
Severe Thunderstorm Watch #448 is now in effect for the
southern Poconos, Lehigh and Delaware Valleys including
Philadelphia, and all but extreme southeast New Jersey until 11
pm.
Confidence has increased in potential flash flooding impacts
across portions of the area on Sunday and Monday. Otherwise, the
forecast remains in track.
&&
.KEY MESSAGES...
1. Dangerous heat and humidity will continue across the region
through Saturday. All time record high temperatures could be
challenged again today with widespread triple digit
temperatures.
2. Daily chances for showers and storms will begin across the
area today and continue into early next week. Some severe storms
are possible each day through Sunday. There is a risk of flash
flooding Sunday and Monday.
&&
.DISCUSSION...
KEY MESSAGE 1...Dangerous heat and humidity will continue
across the region through Saturday. All time record high
temperatures could be challenged again today with widespread
triple digit temperatures.
Strong mid-level ridging across the Mississippi Valley, Great
Lakes, and Ohio Valleys has built eastward into the Northeast
and Mid Atlantic and will persist into the holiday weekend. The
flow is west to northwest today. The ridge will finally start to
break and retreat some starting Saturday, and especially into
Sunday.
Temperatures will begin to abate somewhat on Saturday as the
ridge begins to break and retreat to the southwest. However,
high temperatures will still be in the mid 90s to around 100
degrees, hottest along and southeast of I-95. Another day of
west to northwest flow of similar magnitude should once again
support the immediate coastline warming up considerably before
the sea breeze develops. Elsewhere, a gradually weakening ridge
aloft will result in the slightly cooler temperatures. Dewpoints
should mix out again into the upper 60s to near 70 degrees by
afternoon, which results in 100-108 degree heat indices.
Notably cooler temperatures are expected across the region on
Sunday, with high temperatures generally in the upper 80s across
most of eastern PA and NJ, and low 90s for the urban corridor
as well as Delmarva. With that said, dewpoints will remain in
the upper 60s to low 70s, with heat indices getting into the mid
90s to low 100s from the Philly metro and south. By Monday,
with a frontal boundary draped across the area, much cooler
temperatures are expected. Placement of the front is uncertain,
but north of the front temperatures will likely only be in the
mid 70s, and low to mid 80s to the south. South of the front
where temperatures are still fairly warm, the forecast remains
complicated by the potential for widespread showers and storms.
Significant impacts will continue from the 3 to 4 day excessive
heat and humidity, with heat indices reaching into the 100-110
degree range each day. The Extreme Heat Warning for our entire
forecast area (excluding the New Jersey barrier islands) remains
in effect through 8 PM Saturday. The hottest conditions are
forecast to occur through today south of I-78. While heat
indices may fall just shy of warning criteria by Saturday,
impacts will likely be worsened by the multiple days of heat and
busy outdoor holiday festivities.
KEY MESSAGE 2...Daily chances for showers and storms will begin
across the area today and continue into early next week. Some
severe storms are possible each day through Sunday. There is a
risk of flash flooding Sunday and Monday.
Severe Thunderstorm Watch #448 is now in effect for the
southern Poconos, Lehigh and Delaware Valleys including
Philadelphia, and all but extreme southeast New Jersey until 11
pm.
The mid-level ridge looks to break down and retrograde back to
the south and west starting later today, and this will allow a
mid- level trough to dig southeastward into New England. With
several shortwaves riding over the top of the ridge and into the
local area, this will support increasing coverage of afternoon
and evening showers and thunderstorms starting late this
afternoon, but especially on Saturday and Sunday as a cold front
enters the region and then likely stalls. Currently, PoPs are
around 20-30% this afternoon and evening and generally 30-60% on
Saturday. Activity becomes more widespread on Sunday and
Monday, with PoPs around 60- 90% for most of the area.
SPC has highlighted portions of our area in a Slight Risk
(level 2 out of 5) for severe thunderstorms today, Saturday, and
Sunday. As indicated by the PoP forecast above, coverage of
storms is anticipated to be relatively low today, mainly
isolated to scattered in nature at best. Coverage and
organization of storms should be a bit greater on Saturday
though. Damaging winds will be the main threat with any
thunderstorm development.
While there is still some uncertainty in the details of the
thunderstorm activity Friday and Saturday, it is important to
point out that any holiday weekend festivities could be impacted
by thunderstorms (in addition to the extreme heat).
On Sunday, the severe weather threat is expected to become
confined to mainly the Philly metro and points south, but this
will be dependent on frontal placement. However, widespread
showers and storms are also expected north of the front. The
severe weather threat looks low on Monday, but additional rounds
of showers and storms appear likely through Monday night.
Concern has grown this afternoon that a threat for flash
flooding could evolve Sunday into Monday, given a slow moving or
stationary frontal boundary draped across the area, and tall,
skinny CAPE profiles with deep moisture. In fact, model guidance
is indicating PWATs potentially exceeding 2 inches, which is
above the 90th percentile for this time of year and near the
daily observed maximum. Given these factors, rainfall rates in
storms could exceed 1 to 2 inches per hour. As of now, the WPC
has placed a Slight Risk (2 of 4) for the I-95 corridor and
points west both Sunday and Monday, with a Marginal Risk (1 of
4) for the remainder of the area.
The front is expected to finally clear the area Tuesday, with
high pressure at least briefly building back into the region.
However, daily chances for isolated, primarily diurnally driven
convection, could continue through the middle of next week.
&&
.AVIATION /20Z FRIDAY THROUGH WEDNESDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG,
KILG, KMIV, KACY and surrounding areas.
This evening...VFR. Generally westerly winds around 10 kts with
some gusts up near 20 kts. Very low risk of isolated
thunderstorms after 21Z (about 20-30% chance), but for now kept
it as just VCTS. High confidence overall.
Overnight...VFR. West winds near 5 kts. High confidence.
Saturday...VFR overall. Risk of scattered showers/t-storms after
18Z (about 30-50% chance). Winds generally westerly increasing
to 10 kts with some afternoon gusts up to 20 kts. Moderate
confidence.
Outlook...
Saturday night...Scattered showers and storms will be possible,
especially during the evening showers. Sub-VFR conditions are
likely with any heavier showers or storms.
Sunday through Monday night...Scattered to widespread showers
and thunderstorms with sub-VFR conditions expected at times.
Tuesday through Wednesday...Primarily VFR. Isolated to
scattered showers and storms will be possible, especially in the
afternoon hours each day, which could lead to brief periods of
sub-VFR conditions.
&&
.MARINE...
No marine hazards expected through Saturday. South to southwest
winds 10-15 kts. Seas 1-3 feet. 10-20% chance of a
thunderstorm tonight, 20-40% Saturday afternoon, otherwise fair
weather and hazy.
Outlook...
No marine headlines are currently anticipated through Wednesday
with winds below 25 kt and seas below 5 feet. Showers and
storms are possible each day, with activity being the most
widespread Sunday through Monday night. Visibility restrictions
and strong winds are possible with the strongest storms.
Rip Currents...
For Saturday, winds will be from the west to southwest at 10 to
15 mph with gusts up to 20 mph in the afternoon. Breaking waves
will be around 1 to 2 feet. There will be a weak southeast
swell with a period around 8 seconds. This results in a LOW risk
for the development of dangerous and life threatening rip
currents at the Jersey Shore and at Delaware Beaches.
For Sunday, winds will be from the east around 10 mph with
gusts up to 15 mph in the afternoon. Breaking waves will be
around 1 foot or less. There will be a weak southeast swell
with a period around 8 seconds. This results in a LOW risk for
the development of dangerous and life threatening rip currents
at the Jersey Shore and at Delaware Beaches.
