A SUPERCELL THUNDERSTORM SPAWNED A BRIEF TORNADO JUST NORTH OF HARWOOD, MD (4 SOUTHWEST OF LONDONTOWNE) IN ANNE ARUNDEL COUNTY LATE TUESDAY AFTERNOON JULY 5, 2022, BETWEEN 5:55 AND 5:56 PM EDT.
THIS SUPERCELL ORIGINALLY DEVELOPED ALONG THE HOWARD/MONTGOMERY COUNTY LINE AS A RESULT OF A REMNANT MESOSCALE CONVECTIVE VORTEX (MCV) MOVING THROUGH THE REGION WHICH HAD EARLIER MOVED THROUGH THE OHIO VALLEY EARLIER IN THE DAY. IT EVOLVED INTO A CLUSTER OF CELLS INITIALLY BEFORE SPLITTING OFF INTO AN INDIVIDUAL SUPERCELL THAT WOULD DEVELOP ROTATION AS IT MOVED OUT OF SOUTHEASTERN MONTGOMERY COUNTY INTO NORTHWESTERN PRINCE GEORGES COUNTY. THE CELL DROPPED A TORNADO EARLIER IN THE AFTERNOON NEAR BOWIE, AND WOULD THEN CYCLE TO PRODUCE THE SECOND TORNADO IN HARWOOD.
