I do

[Yardstickgozinya]

I absolutely hate canadian air and blue bird skies. Reminds of fall and another boring weather periods. If it's gonna be cooler, the sky needs to least be filled with cumulus congestis to keep hopes alive and promote the top water bite.

[Yardstickgozinya]

The sun sucks, cumulus clouds are way cooler to look at.

[Superstorm]

Today is not as bad as I feared it would be. Having said that, I completely agree with the sentiment. 

Only got to upper 80s. Not sure what heat index got to.

Mine never got above 93. Well short of where models had it.

I don't believe all the convection, allowing models bring storms this far south and east, This morning, two of  three brought that early morning Glaks complex through our area with some strong embedded thunderstorms. And that never happened. The other one dropped a complex through western pennsylvania, and that never happened either. Nevertheless, we have thunderstorms heading in this general direction, and we have plenty of a destabilized environment.

Wonder what kept temps down so much today

Storms were pretty bad in Lanco. Lots of thunder and lightning and flooding. Woke me up at 1:00 am.

[Yardstickgozinya]

We're working with stable lapse rates today compared to previous days. We don't have 6 to 7°C cooling per kilometer this evening and these storms aren't maintaining vigor quite like they've been the past few nights. I'm not saying there won't be storms in the area tonight  just pointing out an observation.

I'm talking about the complex that I posted about around 4:30 in the morning that was due to get here around 8:00 9:00 am this morning If it made it.  I stayed up all night last night watching lightning and listening to thunder. Im prepared to do the same tonight If need be, we don't get these patterns too often and i'm not one to miss it.

That was a beautiful bow echo . Even had the hallmark bookend vorticity. Unfortunately, when it exited that small finger of better low-level lapse rates, it just couldn't maintain that kind of storm vigor.. It is going to run into better mid-level lapse rate as it nears the susquehanna river. 

 

[Yardstickgozinya]

   Since i'm already on the bender, I figured why not watch hall y'alls winter forecast. That old four eyed dork is looking as lean and handsome as ever I must say. Anywho, he expects the northeast and mid atlantic will get a snow or ice storm that exceeds expectations.  That sums up his winter outlook for our area.

AUGUST 2026 RECAP

With the active weather the past few days, we have not had a chance to review the final month of Meteorological Summer. Here are the final stats for August 2026 at the Susquehanna Valley's official NWS climate site - Harrisburg International Airport (HIA).

August 2026 tied for the 35th warmest August and 61st wettest August on record (out of 139 years). #PAwx #WGALWeather

SUMMER 2026 RECAP 

We still have a few weeks of Astronomical Summer left, but Meteorological Summer ended earlier this week. Here is a look at the final statistics for Summer 2026 from the Susquehanna Valley's official NWS climate site - Harrisburg International Airport (HAI).

We had 3 days with highs in the 100s. The last time we had 3 days or more in the 100s during a summer season was 1999. Even though we had some incredibly hot days, we were only 0.8° above average for the whole season. This places Summer 2026 as the 15th warmest on record (out of 139 years).

Summer 2026 was dry for some and wet for others in the Susquehanna Valley. At Harrisburg International Airport, it was dry with only 9.05" recorded all season. This is 3.44" below average and places Summer 2026 as the 47th driest Summer on record (out of 139 years).

NOTE - some areas across the Susquehanna Valley saw very heavy rainfall due to scattered showers and thunderstorms. Due to the high variability with rainfall over short distances, the 9.05" recorded HIA may not reflect the Summer season for everyone in the Susquehanna Valley. #PAwx #WGALWeather

[Mount Joy Snowman]

Low of 69 with .01” of rain. One more humid day before some relief arrives. 

[ChescoWx]

We start to see humidity levels drop today and we will see our temperatures return to near normal today and then below normal through the upcoming Labor Day Weekend. Highs through the weekend will be in the mid to upper 70's and lows in the 50's for most spots with some 40's possible in our coldest valley locations by Monday morning. Slight rain chances tonight and again by next Wednesday night.

[ChescoWx]

13 days of forecasts by ChescoWx and so far we have had better accuracy then the NWS point and click every day.

[Yardstickgozinya]

Unless something happens tonight, I never did end up under a core of any cell over the course of the last several days.

Could there been a possible tornado here in Lancaster County this evening? Here is some of the damage from the White Horse area!! Part of a barn roof gone, a one room school house lost its whole roof, trees down on wires, and debris scattered across farm feilds!! All pics taken within a mile of each other.

I believe it might have been confirmed this afternoon.

[Yardstickgozinya]

 Ring of fire pattern returns later next week ?

I was reading over tonight's Nws forecast discussion and was delighted to hear that we may return to a ring of fire pattern later next week. The good news for most of you reading this is that I haven't heard mention of that possibility anywhere else to this point. The spc does mention the return of thunderstorms in the northeast and mid atlantic next thursday but doesn't give any mention of any anomalous ridge  and believes the best large scale assent will remain north of the continental border.

Survey Summary:
At 7:44 p.m. local time on September 1, 2026 an EF-1 tornado,
with maximum wind speeds of 90 mph, touched down in Salisbury
Township northwest of the Mount Vernon Road and Old Philadelphia
Pike intersection with a width of 100 yards. It traveled south as
it ripped off the roof of a barn and threw sections through the
Old Road Mennonite Church graveyard before crossing Old
Philadelphia Pike and paralleling Mount Vernon Road. It ripped a
roof off another barn and snapped many larger limbs from a tree
in the neighboring pasture. Continuing south it took some
sections of roof and loose items from three farm outbuildings and
ejected them throughout the fields. As it continued along Mount
Vernon Road, a clump of trees was hit where many trees were
uprooted and large branches snapped. Farther south, a barn
sustained some minor roof damage before a one room school house
was impacted with its whole roof torn off. At the intersection of
Buena Vista Road and Mount Vernon Road, another tree was uprooted
and a telephone pole was bent. It continued south to the east of
Mount Vernon Road where it crossed Pequea Creek, snapping many
large branches and uprooting a few more trees. Past the creek,
another clump of trees saw large branches snapped before the
tornado dissipated in a field.

We would like to thank Lancaster County Emergency Management and
Salisbury Township officials for their assistance in this damage
survey.

Survey Summary:
During the evening of September 1st, 2026, a supercell
thunderstorm moved southeastward through Montour County, resulting
in a brief EF-1 tornado, which impacted southern portions of the
county in Derry Township. We also found damage due to a downburst
that occurred on the north side of the tornado, associated with
the forward flank downdraft of this supercell. Maximum wind speeds
from this tornado were estimated to be 100 mph, and the tornado
had a maximum path width of 250 yards. Tornadic damage was first
noted in the woods between Steffens Rd and Indian Run Rd, with a
start time of 5:40 PM local time. The tornadic damage was
primarily on Stable Ln and the hairpin turn on Indian Run Rd. In
this location, two large trees snapped and fell on a shed, with a
trail of snapped and uprooted trees into the woods beyond the
property. The tornado continued eastward before dissipating near
Fossil Hill Rd at 5:41 PM local time. Surrounding this track,
numerous trees were snapped and uprooted from straight-line winds,
making a broadly divergent pattern particularly to the north of
the tornado path.

We would like to thank Montour County Emergency
Management, local homeowners, and other members of the local
community for their assistance in this damage survey.

Survey Summary:
On September 1, 2026 at approximately 5:33 PM EDT, an EF-1
tornado impacted areas of eastern Potter County and western Tioga
County in the vicinity of Gaines Township. Maximum wind speeds
were estimated at 110 mph with a maximum path width of 150 yards.

Damage associated with the tornado began north of Galeton near
Phoenix Run in Pike Township, where multiple hardwood trees were
snapped along with numerous large branches on both sides of
Phoenix Road. There was more extensive damage just east of Phoenix
Road, where a larger swath of EF-1 damage was observed with some
uprooted trees alongside snapped trees and large branches. Damage
continued southeastward on Phoenix Road in Potter County with more
sporadic damage including broken large branches and snapped
trees. There was an area where the tornado potentially lifted as
it approached US Route 6 with damage being largely sporadic and
not as concentrated as it crossed the roadway.

Once crossing US Route 6, more widespread damage was observed
across Hanky Panky Road in Gaines Township, Tioga County. Numerous
uprooted and snapped trees were observed across approximately a
150 yard segment with eyewitnesses mentioning that there were
trees across the roadway in a convergent pattern. This damage
continued towards the intersections of Dingman Road and Bloody Run
Road, where concentrated areas of snapped and uprooted trees
continued to be observed. There was another eyewitness that noted
multiple trees uprooted at their residence on Dingman Road with
what appeared to be a convergent pattern. As the storm continued
into Marshlands, multiple large branches as well as uprooted and
snapped trees were in a convergent pattern, with surrounding
vegetation also outlining a convergent pattern. The tornado likely
continued to parallel Elk Run Road just south of the roadway
before dissipating on the north side of the intersection with
Straight Run Road.

We would like to thank Gaines Township Emergency Management,
Tioga County Emergency Management, multiple first responders, and
the multiple eyewitnesses from Gaines Township for their
assistance with this damage survey.
