That line on the eastern shore is just sitting there... I wonder if it is being helped by some sea breeze.

Got to be. Seabreeze rolling in on the Atlantic side in Rehoboth, but no initiation here for whatever reason.

Damn. 0.59" in 14 minutes. Needed the rain but that was pretty intense.

Nothing here, but JUST to my west a barely moving storm with red and white radar returns..... I'd say they are getting quite wet.

From this morning LWX AFD re heavy rain threat

Flash Flood Threat: This is likely to be the biggest threat of the
day as multiple rounds of showers and thunderstorms move across the
area. WPC has expanded the Slight Risk of flooding to encompass most
areas along/north of I-66, the northern Shenandoah Valley, and
Alleghenies. Widespread rainfall amounts of 1-2 inches is likely,
with isolated amounts up to 3-4 inches is possible.

A very important feature to watch is the subtle surface boundary
located from Central VA to around Norfolk early this morning. The
increasing southerly flow will push this boundary north into our
area this afternoon, likely somewhere along or north of the Potomac
River. Storms today are likely to be efficient rain producers given
the deep warm cloud layer, a moist airmass, sufficient shear, and
low-level convergence into the previously mentioned boundary. While
mean storm motion is likely to be fast, around 15-20 knots, the
multiple rounds of heavy rain could cause issues in urban areas.

The 00Z guidance shows the potential for locally heavy rainfall, but
exactly where that occurs remains to be seen. The heavy rain
footprint various still varies quite a bit from model to model,
which is expected in this type of disorganized/cluster storm mode.
Given the sensitivities of the DC and Baltimore metros, a targeted
Flood Watch has been issued from 12PM today through tonight to
account for possible flash flooding due to multiple rounds of
storms. Elsewhere, FFG values are high enough and convection spaced
out enough that a Flood Watch is not warranted at this time.
However, the current watch may be expanded later today depending on
future model data.
