Capital City Airport (KCXY) & Harrisburg International Airport (KMDT) are only about 5.36 miles apart as a crow flies. KCXY is roughly 5.2 miles north and 1.3 miles west of KMDT. I bring this up due to the YTD rainfall of each. As of AUG 9th KCXY was at 34.98” and KMDT was at 40.72”. I thought that was a decent difference (5.74” & 16.4% > KCXY).

I pull up 2017 rainfall for the same dates. KCXY was at 23.00” and KMDT was at 32.02”. Nothing like a 12.02” difference (52.3% > KCXY). Now that difference did close some through the rest of the year (see below). For curiosity sake I went through the last 15 years of data as shown below.




Who knew that 5 miles could mean an extra 4”(11.1% >)(median) - 6.5”(17.6% >)(mean) of rain a year. My favorite is 2011, 73.73” vs 51.28”.

Any Mets want to jump in with some reasons for this little microclimate quark?

Fantastic data. Thank you for researching and sharing.

I am a couple days from leaving for Hell, Texas, and my life is already descending into Hell herei n VA as mom continues her control freak stranglehold on my poor little life.

It is going to be excruciating for the next 5 years at least.

I wish I did not have to go.

I actually would rather be dead. It would be much better, lol.

This is NOT gonna be fun. It will be Hell on Earth.

Tacos and a #4 double from Whataburger will save you.

My nephew is on the Post Oak (TX) team. They should whip most teams in Williamsport - they’re absolutely loaded. 

MDT is 16.51” above average year-to-date rainfall as of today. 

Wow. 

That's awesome!

That line farther north produced  about 3.5" in Reading and Allentown. Parts of the Musikfest festival grounds along the Monocacy Creek in Bethlehem flooded this morning.

Oh wow had no idea. We had mostly right rain but it did get a bit heavy around 10ish. HBg for once missed the heavy stuff - too far west. 

That line from York to Lancaster was impressive. 

Newsflash: it’s still raining

UPDATE: Thy did survive ...

Big line of storms west of a Chambersbirg to Newport Line. Wonder if they can keep it together as they cross the mountains?

Wednesday might be interesting with severe wx.

Back to the weather - while it's about to pour rain again for a few hours here (nice 20 percent chance of rain we had this morning haha), this is INSANE:

@NWSStateCollege
We have now finalized the 5-day rainfall total for Dehart Dam. 16.75" fell between Saturday 7/21 and Thursday 7/26. That total includes a 1-day rainfall of 8.11" on Tuesday. Crazy amounts of rain! #PAwx

so is that why this Meteorologist left the company too? I read all about the others, but she just kinda disappeared. 

I believe so; I don't know her at all but have heard she quickly found a new job and bolted.

I guess Ann Rodden, the weekend weather person at WHTM is now gone too. What the hell is going on at that station?

Combo of sexual harassment and gender bias. Hopefully Flora's lawsuit goes through and they all win and put them out of business.

Well....that was a really sad storm through the carlisle/camp hill area gotta say. Glad we didnt get heavy rain but man did it disappoint in terms of anything. Guess we'll see what next week brings

It looks less and less serious. 

Thankfully that was a massive nothingburger for the HBG region. No wind at all, light gray skies, light rain for 20 or so minutes. I got .15” at my house.

Very glad we finally caught a break.

Is it me or does the system next week look like it's not going to end up being too much of an issue - just random passing showers for a day or two?

Oh cool another FFW.

...FLASH FLOOD WATCH IN EFFECT FROM 1 PM EDT THIS AFTERNOON
THROUGH THIS EVENING...

The National Weather Service in State College has issued a

* Flash Flood Watch for a portion of central Pennsylvania,
  including the following areas, Adams, Dauphin, Lancaster,
  Lebanon, Schuylkill, and York.

* From 1 PM EDT this afternoon through this evening

* Showers and thunderstorms will develop this afternoon and
  continue through late evening, with heavy rainfall rates
  likely. Given saturated soil from this week`s excessive
  rainfall, flash flooding may again result.

The Susquehanna at Harrisburg crested an hour or so ago at 17’ even and is now falling. The city itself got extremely lucky it was so low prior to Sunday.

I don’t like the wording CTP is using in the discussion. 

.LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/...
Med range guidance remains in fairly good agreement into next
week, all of which track surface high pressure across the state
this weekend. By next week, a deepening upper trough over the
Miss Valley, combined with an anomalous upper ridge off the
east coast, could potentially result in another atmospheric
river setup along the east coast.

A generally dry and seasonable weekend appears likely, as high
pressure drifts across the state. However, can`t rule out a
stray shower each day in association with the passage of a pair
of shortwaves.

Early next week is looking increasingly wet, as deep plume of
tropical moisture overruns an approaching warm front. Med range
models indicate warm front is likely to lift north of the state
Tue/Wed. However, central Pa will remain within belt of
anomalous pwats and susceptible to widespread, diurnally-driven
convection into midweek.

I am putting down I ended with 10.75" rain from this event. It likely is off because my gauge was knocked over twice but looking around at totals I feel comfortable there. 

The river is quite angry this morning. I'll get some photos or videos after work if the light is OK. If not tomorrow morning I will. 

I think it’s finaly over ...

It’s backbuilt in strength, which I didn’t expect.

Also, I have this nagging feeling that when it does reach my location, the back edge will be moving faster than the leading edge and it'll be in and out in 15 minutes. If you've watched my posts, the radar, and the general weather pattern in and around Tamaqua, you'll see that it's been this way for years. No matter what kind of event, set up, or season.

Hell, even the worst storm in probably a century (Sandy) was rather benign here. There is definitely something about the geography and topography of northeastern Schuylkill County that tames or prevents any kind of severe event here.

I mentioned this the other day but I’d be very interested in a thermal dynamics study.

The lower Susquehanna Valley for a decade or more has cashed in on all sorts of extreme setups - snow, rain, wind. The exact same spots.

I’m in it now and this is the heaviest I have seen from this whole event 

That first cell skirted the city proper - it rained but we’ve had heavier - but it appears our luck(lol) runs out soon,
