Meteorological summer is upon us.

PDS Tornado Watch 333 in effect until 9PM EDT June 23 2020 Hazards: Numerous long-track intense tornadoes likely Numerous significant wind gusts to 105 mph likely Widespread large hail with scattered giant hail events to 4" in diameter likely Discussion: A well-developed and intense MCS/derecho continues to move through much of West Virginia AOA 65kts. The environment within the watch area is characterized by extreme instability (MLCAPE 6000+ J/kg), impressive shear (EBWD 60-80 kts), high moisture content (Pwats of 2-2.25"+) and strong DCAPE (1200-1500+ J/kg). As the MCS moves into the mountains additional supercells are expected to rapidly develop by 19-20z along the foothills/Blue ridge ahead of the main line and move east through the DC and Baltimore metropolitan areas. With the very strong low-level shear also in place (effective SRH of 300-600 m2/s2) these cells will have the greatest risk of producing long-track strong to violent tornadoes as well as very large to giant hail. The greatest wind threat over this region will come with the main line of storms between 20-23z with high-end severe winds (possibly in excess of 100 mph). Storms will move out of the watch area by 00z. Forecaster: George BM

Many thanks to you all for the birthday wishes, Weather family!

Congrats intermountain NW?

I'm just glad that I was not old enough (4 years old) to remember that debacle of an 'event'.

How much rain has your yard picked up so far this morning?

Yeap.

August. August 9, 2000 to be exact. It was even Severe Thunderstorm Watch 666. Lol.

For todays risk look out for how much high level cloud cover we get from the storms currently developing in the Carolinas.

It's the most humid day of the year so far. It's the first 70+F dewpoint day of the year.

There hasn't been a MOD or HIGH risk issued anywhere in the country this month from SPC. Quiet indeed. One time period that I'll watch is following the cool shot at the beginning of next week. As a ridge tries to build in during the week watch for any potential NW-flow event. Small note: Some of the 0z convective models hint at scattered storms/convection trying to develop tomorrow afternoon from Bertha. There looks like there will be some low-level shear (not super impressive LLshear but some LLshear). If storms can develop tomorrow there might be a risk of gusty winds and perhaps a rotating meso or two. #Notanexpertopinion

I just got a new Honda HRN216VKA self-propelled push mower (a durable mower) after the Toro that we had since 2003 finally gave up the ghost last month if this adds anything of value for you.

^There's a tropical wave with a surface trough affecting Cuba and Florida with heavy rains now. A few models actually try to spin-up something weak (probably too weak for any tropical classification) from this. This would be especially true if the disturbance moves off the east coast of Florida, Georgia and into the Carolinas. Regardless, this would result in the high Pwats in the region by mid/late week. #Notanexpertopinion

@H2O Happy 49ing!...Or is it 50ing? I'm pretty sure it's forty-nining IIRC.

Is this a future storm in the GOM this year? Also, do we get some decent remnants from it up here?

I should probably start checking myself for ticks from time to time... especially considering that I occasionally walk/hike/run through tall grass and weeds in my local park (I like going through the wilderness off the paved surfaces).

Don't forget places immediately to your east and southeast like VA beach, the lower Virginia peninsula and Delaware getting into Arthur's rains as well.

But was it good though?

I've never drank once in my life before.

IAD got down to 34F this morning. I noticed some patchy frost on roofs here. (Herndon)

Minus the rain, this has been an epic stretch of weather for you.

Someone has been time-traveling I see.

Despite being down to 33F by the 1am hour that's where IAD bottomed out this morning.
