.WHAT HAS CHANGED...
*Lowered dewpoints and minimum RH this afternoon
*WPC added a level 1/4 excessive rain risk for Monday 7/27

.KEY MESSAGES...
1) Pleasant/dry pattern continues into the last weekend of July
2) More humid with potential for strong thunderstorms and heavy
rainfall into next week

.DISCUSSION...
KEY MESSAGE 1: Pleasant/dry pattern continues into the last
weekend of July

Valley fog continues to expand over the N&W Alleghenies per
latest IR satellite loop. Based on 07Z observations, some of
the usually colder sites in this area could print morning low
temps in the upper 30s.

Fog will quickly dissipate shortly after sunrise with temps
also rebounding nicely under abundant sunshine. The pleasant/dry
pattern continues into the last weekend of July. Sounding
profiles supported lowering Td this afternoon further reducing
RH which is already quite comfortable for this time of year.
High pressure migrates over CPA tonight setting up another
seasonably cool/comfortable night with more valley fog into
early Friday morning.

Wind flow shifting from the north to the south signals a slight
warming trend and gradual increase in low level moisture Friday
and Saturday. A stray shower or t-storm can`t be ruled out
Saturday afternoon/evening over western PA with precip odds less
than 20%.

KEY MESSAGE 2: More humid with potential for strong thunderstorms
and heavy rainfall into next week

The pattern looks increasingly unsettled Sunday into the middle
of next week as upper troughing is carved out over the Great
Lakes/Ohio Valley into the Mid-Atlantic and Northeast states.
Ample northern stream system energies set to dig into the upper
trough position will support potential for strong storms and
heavy rainfall. WPC introduced a broad level 1/4 marginal
excessive rain risk for D5/Monday July 27 that covers most of
CPA. Severe storm potential could shift east/southeast on
Tuesday. Confidence in where greater risk corridors may develop
is low, and will largely be influenced by convective evolution
in the Days 4-5/Sunday-Monday periods.

&&

.AVIATION /06Z THURSDAY THROUGH MONDAY/...
High pressure over the central states will slowly build
eastward into Pennsylvania over the next few days. Stratocumulus
and cumulus clouds should erode away overnight as drier air
continues to move in. Tapering winds and clearing skies will
support fog in the deepest valleys across northern PA by
Thursday morning. No impacts are expected at area airfields, but
the current TAF package includes a mention of vicinity fog at
KBFD as that location has the relatively highest chance of
impacts.

VFR conditions should prevail into at least the first part of
Saturday, before the chances of showers and storms increase
later in the weekend. Each day will be marked by dry conditions
and generally tranquil weather - ideal for flying.

Outlook...

Fri...Some potential for valley fog across NW PA Friday
morning; otherwise, VFR conditions expected.

Sat...Generally VFR conditions with low-end (< 20%) chance of an
afternoon shower/storm across western sections of central PA.

Sun...Increasing chances of PM showers/storms, with some
restrictions possible.

Mon...Still a chance showers and storms.

&&

.CTP WATCHES/WARNINGS/ADVISORIES...
None.

...NWS Damage Survey for 07/18/26 Tornado Event...

.Overview...

A damage survey conducted on Monday July 20th confirmed an EF-2
tornado occurred in Franklin Township, Huntingdon County on the
evening of Saturday July 18, 2026. The tornado damaged a few
structures and produced significant tree damage along and just
south of Old Mill Rd. Details of the survey follow.

..Old Mill Rd Tornado...

Rating: EF2
Estimated Peak Wind: 125 mph
Path Length /statute/: 0.53 miles
Path Width /maximum/: 500 yards
Fatalities: 0
Injuries: 0

Start Date: 07/18/2026
Start Time: 08:43 PM EDT
Start Location: 3 NNE Spruce Creek / Huntingdon County / PA
Start Lat/Lon: 40.6551 / -78.116

End Date: 07/18/2026
End Time: 08:45 PM EDT
End Location: 2 W Franklinville / Huntingdon County / PA
End Lat/Lon: 40.6531 / -78.1063

Survey Summary:
The same storm that produced the tornado in Houtzdale (Clearfield
County) continued southeast into Huntingdon County on Saturday
evening. It started producing minor damage again as it crossed
Huntingdon Furnace Road just northwest of Turnpike Rd as it
knocked down some corn stalks. Strong downdraft winds knocked down
several 200+ year old pine trees in front of a farm house on
Huntingdon Furnace Rd along with a couple smaller trees in the
farm field and then the tornado began moments later.

The first structural damage was observed as the roof of the oldest
of 3 large silos was partially blown off toward the northeast,
exhibiting a cyclonic wind pattern. The southern half of a large
barn roof collapsed and was blown northeast as well. An adjacent
barn had several sheets of its tin roof blown northeast into the
adjacent field as well. The circulation then continued east-
southeast paralleling Warriors Mark Run and Old Mill Rd and
produced an incredible amount of tree damage as it moved up a
small ridge. Hundreds of trees were snapped off 20-30 feet up or
uprooted along the path of the tornado. Notably, trees were thrown
in an easterly direction to the right of the tornado path and
northwesterly to the left of the path. This pattern, along with
the evident path of damage left no doubt that the damage was
caused by a tornado.

There were also several cabins in the densely wooded area through
which the tornado passed. One cabin, which was inhabited by two
individuals in their 80s, had a tree fall on one side of it.
Fortunately, both individuals were safely sheltered on the
opposite side of the house and were able to escape unscathed. The
other cabins suffered no damage, though inhabitants were unable to
enter or exit the camp until significant clearing efforts were
undertaken. The tornado continued east- southeastward toward Camp
Kanesatake and lifted as it moved across Old Mill Rd on the north
edge of the camp. Sporadic tree damage was observed downstream at
Camp K, but none of it was concentrated enough to extend the
tornado path at this time.

We would like to thank Huntingdon County Emergency Management and
Franklin Township for their assistance with today`s survey.
