Superstorm

55.6F

Very nice fall like morning.

56.7 F in Lancaster.


Refreshing.

@MUweather
Due primarily to oppressively warm nights and a slew of days with highs between 89-95F, #July2025 concluded as the 2nd-hottest on record @millersvilleu since 1914. It was also the 10th-wettest on record thanks to a seemingly endless onslaught of slow-moving, drenching T-storms.

1.56” in rain gauge.

Got down to 64F.

Beautiful 68F right now.

1.50" so far.

And so it begins....Flood Warnings have been issued.

From CTP:

Southern/Southeastern PA/Lower Susquehanna Valley
Farther south, this area is more removed from the jet-streak
dynamics to the north. However, this region is closer to the
deepening surface low with strong surface-925mb southerly
theta-e advection directed into the southeastward advancing
surface front. A tropical air-mass (depicted by 2-2.25" PWATs
and low-mid 70s dew points) will coincide within a warm sector
that becomes increasingly unstable (MUCAPE between 1,000-2,000
J/kg). It is worth noting that SST anomalies along the Mid-
Atlantic and Southeast coasts are well above normal too, acting
as an abnormally rich moisture source for southerly low-level
flow to draw from. By this afternoon, low-level WAA into the
front will support storms enveloping the region with additional
storms from the Laurel Highlands/south central Alleghenies
tracking east. Modest vertical wind shear aloft will also
support organized clusters of storms, some of which will have
the potential to backbuild and train between the I-81 and I-95
corridors into tonight. Latest 12Z HREF guidance shows 24-hr
probabilities for >3" of rainfall are high (>70%) across southeast
PA. Just as concerning is this same region sports 30-60%
chances for >5" of rainfall with 24hr PMM/LPMM values close to
the ensemble maxima approaching 8 inches.

That is nuts.  Whoever gets in the deluge will be suffering some serious flooding.

...FLOOD WATCH IN EFFECT FROM THURSDAY AFTERNOON THROUGH LATE THURSDAY NIGHT...

* WHAT...Flash flooding caused by excessive rainfall is possible.

* WHERE...A portion of central Pennsylvania, including the following counties, Adams, Lancaster and York.

* WHEN...From Thursday afternoon through late Thursday night.

* IMPACTS...Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations. Flooding may occur in poor drainage and urban areas.

* ADDITIONAL DETAILS...
- Thunderstorms capable of producing very heavy rainfall rates in excess of 2 inches per hour may result in flash flooding. Rainfall amounts of 2 to 3 inches are expected with localized amounts of up to 5 inches possible.

Unfortunately, it also now appears that flood concerns are elevated on Thursday:

.LONG TERM /THURSDAY THROUGH SUNDAY/...
Models show t-storms accompanying the southeastward moving
front through CPA on Thursday. A wave of low pressure is now
progged to move along the boundary, which has trended slower
with its southward/southeastward progression. There also appears
to be some enhanced large scale lift to support +RA in the form
of right entrance region (RER) upper jet dynamics. High rain
rates combined with ample deep layer moisture will continue to
support an excessive rain/flash flood risk particularly across
the southern tier of CPA on Thursday/D4.

The slower southward movement may also delay north to south
clearing, and we can`t rule out a stray shower lingering early
Friday morning in southern tier/far southeast PA. That said,
much of the area will be firmly in the dry/cooler sector by
Friday afternoon.

Behind the front, a comfortably cooler and refreshing airmass
(much lower humidity) is poised to arrive just in time to begin
the month of August. Slightly below average daytime highs
70-80F and lows 50-60F are forecast along with no rainfall through
the first weekend of August. Dewpoints will plummet into the

This is not good.

In this new climate, the south is going to be unlivable.

Wow, Tampa, FL hit 100F for first time ever.

11:15am and it's 89. Feels so much worse. Late next week can't come soon enough. 

Yesterday was not too bad....today, it is BRUTAL.

From MU:
Here’s a fun little stat: there have only been 3, 90-degree days at @millersvilleu so far this month. However, the high temp has reached 89F on an additional 8 days. One single degree is separating us from having 20, 90-degree days so far this season. Instead, there have been 12.

Well, I got the Tempest elevated. It's above the standard 2m height for temperatures, but now it's more open, and above the fence tops for a better opportunity for more accurate wind speeds and directions.
It's a homemade setup using one of the wife's clothesline props, so time will tell how well it holds up. I may need to get a more rigid post, but for now it's better than where it originally was.
 

Radar estimates of 5 to 6 inches.

Lots of high water rescues being called into Mt. Joy and surrounding areas with numerous reports of over 5".

I can wait.

Depends on what Superstorm got. His area got rocked last evening.

I finished with 1.70".

Very green.

[mention=423]Superstorm[/mention] about to get some legit severe stuff there in the Willow Street area. 

This rain is making yesterday's look pedestrian. It is a monsoon. 

Think I’m seeing a bad scenario starting to develop in Lancaster County again.
