I want this setup in January with fresh arctic air.

We have had like 2 nice days out of the last 30, it was 90+ with dews 70+ and then it’s just been gross 80s and moist since. 

I’m a total severe amateur but on the base velocity it looks like an area of green/red coupled together just moved through NW dc and is now up by silver spring.

The highest I found from their observations at the airport is 60kt gusting to 84kt

VHHH 160500Z 07060G84KT 1100 0900W R07R/0400N R25L/0400N R07L/0375N R25R/0325N +SHRA FEW010 SCT025 27/24 Q0975 NOSIG

wow sure looks a lot faster on these videos, I guess funneling as @Windspeed mentioned.

Anyone know what the sustained winds were when it hit Hong Kong? The videos are nuts.

The end of the loop is less than an hour old, but point taken.

It looks remarkably symmetrical here.

Blinding rain in Takoma Park.  Impressive. 

Got a DP of 81 on the local weather station, highest I’ve ever seen here. 

Training over Arlington and the district.  I wanna get this fire hose outta here before my basement caves. 

That’s a lot of slow moving rain about to dump on us.

Storm parked over Takoma Park, torrential rain.

Went for a bike ride and back. That air is horribly dry and sinuses are a little upset because of that. Little spots of green grass, otherwise the other 90% or more of MBY is torch

LOL dews are in the 50s, this is perfect.  I was out in California last week and dews were in the 30s, that was a little rough on the sinuses.

Sure doesn't seem like the high will only be 89 today when it's already 85

Yeah heat index is already 97 here, possibly need another heat advisory.  

One thing I don’t understand about heat index is  they say it “feels like 110”.  But 110 would feel very different with different humidity, is there a set humidity for all heat index temps?

80/79, wow it’s gross out already. 

Obviously a much smaller scale but it had the firehose look that Houston had last summer.

Warning now for DC.

Oh wow, who's going to run the panic room next year?

I get the first mod risk of my life in SNE and I’m out of town  

I hate life lol

What are you doing in East Hartford?

updated day 1

15% wind 15% hail 2% tornado runs along the PA line

 

One source of uncertainty in this scenario is an area of outflow to
   the south, across parts of VA/MD/Delmarva and eastern PA,
   originating from yesterday's MCS, and sampled peripherally by the
   12Z IAD sounding.  Airmass recovery is expected from the southwest,
   around the northwest rim of that outflow pool and south of the
   morning convective/frontal baroclinic zone.  Expect midday to
   afternoon preconvective destabilization arising from both theta-e
   advection and diabatic surface heating.  68-70 F surface dew points,
   such as forecast by the NAM, may be overdone considering the
   available recovery trajectories, and the nearest dew points that
   large are 300-400 nm away over NC, on the other side of the outflow
   pool.

   Regardless, a plume of EML air advecting over this region will
   foster steep midlevel lapse rates, overlying strengthening
   boundary-layer lapse rates and low/mid-60s F surface dew points. 
   That combination still supports peak MLCAPE in the 1500-2500 J/kg
   range, amidst strong west-southwesterly mean-wind and deep-shear
   vectors.  Forecast soundings suggest that, despite a nearly
   unidirectional vertical wind profile, effective-shear magnitudes of
   45-55 kt may be realized.  Downward momentum transfer from strong
   flow above 700 mb, into a well-mixed preconvective boundary layer,
   should offer favorable conditions for severe thunderstorm winds. 
   Given the strong westerly component of the near-surface flow,
   more-unstable inland air may be shunted eastward to very near the
   coast across much of the region, extending the severe threat
   accordingly, before the MCS encounters too much stable marine-layer
   air and weakens.

Where do you get these zoomed in convective outlooks?

Yorktown is a mess, 5500 out of 6500 customers in the town without power...could be a while til it comes back.

At least that much...Irma essentially scrapped PR.

And 70,000 people are still without power from Irma.  I think it's game over for their power grid for a while.

Did Irma's path and intensity create any limiting factors to Maria once it gains latitude?  Upwelling or removal of heat content?  NHC seems bullish on Maria's intensity prospects, and the current path is very concerning for some of those smaller islands and PR.

Where is my best bet if I wanted to drive down to somewhere in st Mary's county and do some snowshoeing or XC skiing?  Is st Mary's river park pretty nice?  Does it have some trails?  I know point lookout is nice but I don't recall it having many trails. 

Getting word that Columbia Heights Education Campus may have to be relocated for repairs.
