This event has arguably earned a spot in my "Weather Event of the Decade" poll. I was just thinking about that. This is my #2 weather event on the year behind the windstorm. I’d have to verify tomorrow, but this should be somewhere in the top 3-5 range of total precipitation events since we moved to our house 9 years ago. Only Lee and Sandy I know are above it. I think we’ll pass last year’s event. Link to comment Share on other sites More sharing options...

HOURLY RAIN TOTALS TO 2" WITH LOCAL AMOUNTS TO 4" ARE EXPECTED THROUGH 07Z, PARTICULARLY ACROSS MD & PA. DISCUSSION...THE 00Z SURFACE ANALYSIS REVEALS AN OCCLUDED CYCLONE IN SOUTHERN CHESAPEAKE BAY WITH AN INCREASINGLY PRONOUNCED DRY SLOT NEAR THE VA CAPES AND EASTERN SHORE. VERY HEAVY RAINFALL NEAR THE POTOMAC RIVER IS BEGINNING TO LESSEN IN MAGNITUDE AND SHIFT SOMEWHAT EASTWARD WITHIN THE TROWAL OF THIS CYCLONE, SHOWING UP AS A SURFACE TROUGH ACTING AS A BOUNDARY BETWEEN NORTHERLY AND EASTERLY SURFACE WINDS. PRECIPITABLE WATER VALUES ARE 1.6-2.5" PER GPS VALUES AND THE WALLOPS VA SOUNDING. INFLOW AT 850 HPA IS EAST-SOUTHEAST AT 25-40 KTS PER VAD WIND PROFILES. EFFECTIVE BULK SHEAR IS 30-40 KTS IN THIS REGION, WHICH HAS ORGANIZED CONVECTION INTO A BAND NEAR THE NATION'S CAPITAL. THE EXPECTATION BASED ON RAP MASS FIELDS IS FOR THE TROWAL TO MORPH INTO A PRONOUNCED COMMA HEAD IN THE NEXT SEVERAL HOURS. THE GUIDANCE SHOWS DECREASING INSTABILITY WITH TIME, SO BELIEVE THAT THE ONGOING FLASH FLOOD EVENT SHOULD EVOLVE INTO A LONGER DURATION HEAVY RAIN EVENT BY 07Z AS HOURLY RAIN TOTALS SLOWLY FADE. HOWEVER, EVEN BY 07Z, AVAILABLE INSTABILITY SHOULD CONTINUE TO SUPPORT HOURLY RAIN TOTALS OVER 1", WHICH WOULD BE PROBLEMATIC IN URBAN AREAS. THE MESOSCALE GUIDANCE ADVERTISES LOCAL AMOUNTS UP TO 4" IN MD/PA AND UP TO 2" IN NJ/NEW YORK CITY THROUGH 07Z. COMBINED WITH PREVIOUS RAINS, STORM TOTALS OF 6-7" ARE POSSIBLE ACROSS MD BEFORE THE HEAVY RAIN SHIFTS NORTHWARD/ENDS. ROTH ATTN...WFO...AKQ...BGM...CTP...LWX...OKX...PHI...

ErinInTheSky Posted July 22, 2018 Share Posted July 22, 2018 All local PWS around me in Germantown are pushing 5". There is one at 8" out with no other PWS nearby, so it's quite suspect, but the way the rain is coming down right over its location and me right now... yeah, lots of rain.
