Second heavy rain meso issued by WPC Mesoscale Precipitation Discussion 0766 NWS Weather Prediction Center College Park MD 1128 AM EDT Sat Jul 18 2026 Areas affected...portions of the coastal Mid-Atlantic Concerning...Heavy rainfall...Flash flooding possible Valid 181528Z - 182128Z Summary...A couple rounds of showers and thunderstorms with heavy rainfall are expected into late this afternoon. Hourly rain amounts to 2.5" are possible, which could lead to flash flooding in urban areas. Discussion...A thermal boundary extends through portions of the Mid-Atlantic States. Near the boundary, showers and thunderstorms are showing some slight backbuilding character while moving northeast into New York City. Precipitable water values are 1.4-2". MU CAPE is 500-5000 J/kg across the region, with the maximum on the Eastern Shore. Effective bulk shear is ~40 kts. One bout of heavy rainfall in the very near term is expected across southeast NY and portions of CT, while later development is expected to the southwest which should ride up the boundary back into the Tri-State area. Hourly rain amounts to 2.5" are possible either from backbuilding, cell training, or mesocyclone formation. This would be most problematic in urban areas.

Sky has brightened

Dunno. I assume fail lol. Maybe if the warm front can push through we can partially clear for a few hours?
-
VA was pretty clear this morning, but cirrus outflow from the PA storms are now expanding over us. Not sure we’re going to clear out at all for the metro areas and points N/E

Come on mama nature, flood me

I can smell it this morning again. Not as strong as yesterday
-
About 0.08” with the morning bonus round. Hopefully 2 more rounds today?
-
Yeah smell is much reduced. Could see 1 star in the sky
-
Solar power was about 70-75% of what it would have been without smoke
-
Hugging the Herpderp. Other mesos look like shit.
-
Yeah, northern edge has pushed south into eastern PA and NJ. WV looks relatively clear. But a firehose of smoke pointed right at central MD
-
Just eyeballing out my office window, it had improved a bit around 11am-12pm but has gotten thicker again since
-
Need a big fat QLCS to blow and rain all the smoke out

Found a link with visible band optical depth. UMBC at ~2.5 and the Maryland science center at ~3. Those are pretty ridiculous.

N95 should help, yes.
