SURVEY SUMMARY:
A LINE EMBEDDED SUPERCELL DEVELOPED AND TRACKED OVER NORTH-CENTRAL
MARYLAND DURING THE LATE MORNING INTO EARLY AFTERNOON HOURS ON
MONDAY, MARCH 16, 2026. THIS STORM WAS PART OF A MUCH LARGER SYSTEM
THAT BROUGHT MULTIPLE ROUNDS OF SEVERE WEATHER TO MUCH OF THE
EASTERN UNITED STATES.
ROTATION WAS EVIDENT WITHIN THE STORM AROUND 2000 TO 3000 FEET ABOVE
GROUND ON THE KLWX WSR-88D RADAR, PROMPTING A TORNADO WARNING AS THE
STORM MOVED FROM FREDERICK INTO CARROLL COUNTY. THE FAA TDWR TBWI
SHOWED THIS ROTATION QUICKLY STRENGTHEN AND LOWER TO BELOW 2000 FEET
JUST TO THE SOUTHEAST OF THE MID-LEVEL MESOCYCLONE BEING SAMPLED BY
THE KLWX WSR-88D. THE TIGHTENED LOWER-LEVEL ROTATION PERSISTED ON
TBWI FOR 1 TO 2 MINUTES AFTER THE MID-LEVEL ROTATION ON KLWX HAD
NOTABLY WEAKENED.
IT WAS BENEATH THE TIGHTENING LOW-LEVEL ROTATION AT AROUND 12:02 PM
EDT THAT THE FIRST EVIDENCE OF TORNADIC DAMAGE WAS FOUND. SEVERAL
TREES IN A WEAKENED STATE JUST SOUTHEAST OF THE INTERSECTION OF
HAWKS HILL ROAD AND BETH WAY SNAPPED NEAR THE TRUNK, AND FELL TOWARD
THE EAST, WEST, AND NORTH. THE PARENT STORM MOTION WAS NORTHEAST.
THE TREES THAT FELL WERE ONLY AROUND 100 FEET APART AT MOST, WITH AN
UNDISTURBED LANDSCAPE AROUND IT INDICATING AN INITIALLY VERY NARROW
VORTEX PERHAPS NO LARGER THAN ABOUT 25 TO 50 YARDS IN WIDTH.
THE TORNADO THEN CROSSED THROUGH OPEN FIELDS, LIFTING THE SOUTH END
OF A LONG IRRIGATION SYSTEM AND ROLLING IT ABOUT 100 FEET TOWARD THE
NORTH JUST EAST OF WINTERS CHURCH ROAD.
AFTER THIS, THE CIRCULATION CONTINUED NORTHEASTWARD CROSSING SEVERAL
MORE FIELDS AND GROVES OF TREES, AS WELL AS LITTLE PIPE CREEK. THE
NEXT VISIBLE AND ACCESSIBLE DAMAGE WAS NOTED AS THE TORNADO
APPROACHED AND CROSSED MD-75 GREEN VALLEY ROAD NEAR THE INTERSECTION
WITH MD-84 UNION BRIDGE ROAD. HERE, A COUPLE DOZEN TREES FELL IN
OPPOSING DIRECTIONS (SOUTHEAST, NORTHEAST, EAST, NORTHWEST, AND
NORTH). ONE LARGE TREE TOPPLED ONTO POWER LINES TAKING DOWN A POWER
POLE AND BRIEFLY TRAPPING A MOTORIST BETWEEN THE DOWNED WIRES, POLE,
AND DOWNED TREES. SEVERAL LARGE PINE TREES AT THE INTERSECTION HAD
THEIR TOPS SHEARED OFF, FALLING TOWARD THE NORTH, NORTHEAST, AND
EAST. TWO TREES ON A HILL JUST EAST OF MILL DALE LANE FELL TOWARD
THE NORTH-NORTHWEST, LIKELY JUST OUTSIDE THE CIRCULATION BUT IN ITS
INFLOW AS IT PASSED ACROSS MD-84 UNION BRIDGE ROAD. MEANWHILE, AN
OUTBUILDING JUST TO THE SOUTHWEST OF MD-75 GREEN VALLEY ROAD
SUFFERED A NEAR TOTAL ROOF COLLAPSE, WITH THE WEST-NORTHWEST FACING
WALLS PARTIALLY COLLAPSED INWARD. SIMILAR TO THE TREES OFF MILL DALE
LANE, THIS OUTBUILDING MAY HAVE BEEN JUST OUTSIDE THE TORNADIC
CIRCULATION, WITH THE DAMAGE A RESULT OF INFLOW WINDS INTO THE
VORTEX AS IT PASSED. IT IS AT THIS POINT WHERE THE TORNADO REACHED
ITS LARGEST AND STRONGEST, WITH AN ESTIMATED PATH WIDTH OF 150 YARDS
AND PEAK WINDS OF 80 MPH. DESPITE THE EXTENT OF THE DAMAGE, ONLY
ABOUT ONE-THIRD OF THE TREES IN ITS PATH AT THIS POINT SUSTAINED
VISIBLE DAMAGE, WITH NO OTHER VISIBLE DAMAGE TO OTHER OUTBUILDINGS
OR THE FARMHOUSE AT THE NEARBY FARM.
A VIDEO TAKEN FROM THE CARROLL COUNTY EMERGENCY OPERATIONS CENTER
SHOWED A SWIFTLY ROTATING LOWERING, LIKELY THE TORNADO IN PROGRESS
AS IT APPROACHED AND CROSSED THE INTERSECTION OF MD-75 GREEN VALLEY
ROAD AND MD-84 UNION BRIDGE ROAD, JUST NORTHWEST OF THEIR FACILITY.
ALTHOUGH TREES IN THE FOREGROUND OBSTRUCTED THE VIEW AND COULD NOT
CONFIRM GROUND CONTACT, THE VIDEO WAS DIRECTLY COINCIDENT WITH RADAR
AND THE OBSERVED (CONVERGENT) DAMAGE.
A FEW TREES HAD THEIR TOPS SNAPPED OFF JUST NORTHEAST OF MD-84 UNION
BRIDGE ROAD, BUT NO VISIBLE DAMAGE WAS NOTED BEYOND THIS POINT. IT
IS POSSIBLE, BASED ON THE ROTATION SIGNATURE ON TBWI, THAT THE
TORNADO COULD HAVE PERSISTED FOR UP TO ANOTHER MILE OVER OPEN
FIELDS, BUT THE PATH LENGTH IN THIS SURVEY CAN ONLY CONFIDENTLY
CONCLUDE A PATH UP TO THIS POINT, APPROXIMATELY 1.68 MILES IN LENGTH.
THE NATIONAL WEATHER SERVICE BALTIMORE/WASHINGTON WEATHER FORECAST
OFFICE THANKS CARROLL COUNTY OFFICE OF EMERGENCY MANAGEMENT FOR
THEIR ASSISTANCE. ADDITIONALLY, THANKS TO THE TRAINED SPOTTERS,
MEDIA, AND PUBLIC THAT SENT IN REPORTS OF DAMAGE.
