    The reds setting up south of DC and rotating northward was expected from the models, my guess is DC and Arlington and Alexandria and such get in on some serious action shortly.

    I ran out of daily "likes" and now's the time I'd want to use them!  Up to 1.25"/hr :)

    Sure was. I live very close to lake needwood but luckily I'm higher ground. A bunch of folks in my neighborhood got evacuated. 

     

    That storm had tropical influence but it was an unusual upper level pattern that squeezed all the juice. Basically right over our heads. Lol. 

    I don't even remember that one!

    .SYNOPSIS...
    Upper-level low pressure system will intensify as it moves into the
    area through tonight. The low will slowly pass through the area
    Saturday before gradually moving away from the coast Saturday night
    into Monday. High pressure is expected to build overhead early next
    week.

    .NEAR TERM /THROUGH TONIGHT/...
    
    We are already issuing FFW`s just west of Washington DC. Radar
    estimates up to 3" of rain in an hour in eastern Montgomery
    County. The 12Z IAD sounding had a PWAT of 1.77" and that should
    continue to increase this afternoon. We are hearing reports of
    water rescues.
    
    See the Mesoscale Precip Discussion that WPC issued at 1040 am -
    excellent discussion of the meteorology expected for this
    afternoon and evening.
    
    I remain most worried about northern VA up to the PA border - as
    I`ve seen in writing this does appear to bear some similarity to
    Nor`easters and makes me think of some of the bigger snowfalls

    I`ve seen here where the CHO area might get 8" and central MD/eastern WV over 20" - as the low pivots off the coast snow will cease in the central Shen Valley but a band will hang on for many hours from Balt and westward. Obviously we`re not talking snow here but believe the rain will hang on through midday Sat across the aforementioned region.

    
    
    Flash flood watch area remains the same but we have pushed the
    start up to 14Z.
    
    A storm total of 2- 4+ inches is possible on average over the
    Watch area.
    
    Coverage expected to increase by afternoon, with the heaviest
    rainfall expected from late afternoon into the overnight as the
    surface low rides crosses the area as it traverses the frontal
    boundary.
    
    While Hydro issues are the primary threat today...some severe
    thunderstorm potential does exist...with a Marginal risk from SPC.
    The primary threat is isolated strong wind gusts due to modest
    instability and relatively strong shear profiles. While we are
    nopt outlooked for a tornado threat we feel spin ups could be a
    concern given low level helicity this evening. This is not in a
    normal quandrant on the hodograph given the easterly flow but
    still bears watching.
    

    Someone's excited! :)
