I knew it was, I was surprised you were still droughted.   I hope Summer 2024-2025 you can drive to the far Western LSV and see lush grass (or jsut beyond in my case).  
Haha, I'm guessing for the great valley to have lush green in heart of summer that he will be driving there on his evacuation route due to Marysville flooding under 25" of rain.

State College radar has some sprinkles, but remember the beam is at 7200 ft and Sterling's beam at Harrisburg is at 8500ft. Which is why everyone's been waiting for that dopplar radar in Lancaster to open. Speaking of which does anyone have any idea what's going on with it?KCCX - Super-Res Reflectivity 1, 5_35 PM.jpg

I don’t believe it’s being made public, which absolutely stinks if true.

Just goes to show how hard this stuff is to predict and how there are always surprises. I don’t think anyone out that way was expecting anything that vigorous this early.

Mesoscale Precipitation Discussion 0841
NWS Weather Prediction Center College Park MD
631 PM EDT Thu Aug 08 2024

Areas affected...Portions of the Mid-Atlantic...

Concerning...Heavy rainfall...Flash flooding possible

Valid 082230Z - 090400Z

SUMMARY...Back-building efficient tropical showers. Banded
streaks of enhanced rainfall and flash flooding likely to continue
through early overnight period.

DISCUSSION...Regional RADAR depicts a tightening mid-level
deformation/FGEN zone highlighted by the more dense stratiform
shield extending from the Blue Ridge across central MD toward the
Delaware River Valley. CIRA LPW and 850-700mb RH analysis
suggests the core of the warm conveyor belt is directed from the
Outer Banks directly up the Chesapeake Bay. It is at this
intersection that the strongest deep layer moisture convergence is
analyzed and 22z surface streamlines veer slightly through the
Delmarva peninsula to enhanced surface moisture convergence. This
has resulted in prolonged training event across N DE with 5"+
rainfall has already fallen; the wave and deformation zone is
lifting slowly into SE PA, but given strong intersection
convergence with the deformation zone broader ascent and a
favorable back-building environment still will remain with very
slow northward progress over the next few hours. Combine this
with frictional convergence affects and additional convective
bands may start to develop across N MD and maintain across W MD/E
WV as well.

A wedge of weak to modest instability (500-1000+ J/kg) is forecast
to maintain given advection off the warmer eastern Atlantic
through the evening. The core of 2.25-2.5" TPW in the warm
conveyor belt will continue to be advected on 40-50kts of 850mb
flow, so efficient flux convergence will continue to support
shallow tropical warm core convection capable of 2-3"/hr rates.
As such, narrow streets of 3-5" remain possible. The MPD area
also aligns with lowered FFG due to recent Predecessor Rainfall
Event (PRE) in the last couple of days. Hourly FFG values less
than 1.5" stretch much of the area of concern with 3-6hr FFG not
much higher at 2.5-3" with exception of Northern VA/southern MD
and S NJ. As such, focused bands of flash flooding are likely
though given the bands will be relatively narrow and widely
scattered.
