Two More Tornadoes

tt_june20_tornadoes

Spring 2009 was cloudy, wet and wild, going out with a round of severe thunderstorms in the final hours of the season. The National Weather Service’s Baltimore/Washington Forecast Office surveyed storm damage in Harford and eastern Baltimore Counties on Sunday and determined two tornadoes did some damage in those areas on Saturday afternoon. The National Weather Service report is posted below.

For those hoping for a change in the cloudy, wet, and stormy weather of spring, keep in mind that the summer solstice occurred at 1:46 a.m. Sunday morning, signaling the official start of a new season…and maybe a new weather pattern.

…TWO TORNADOES AND A WATERSPOUT CONFIRMED FROM SATURDAY…

SATURDAY AFTERNOON THREE WEAKER THUNDERSTORMS DEVELOPED QUICKLY
INTO SUPERCELLS WHILE MOVING ACROSS HARFORD…BALTIMORE…AND ANNE
ARUNDEL COUNTY. MUCH OF THE REASON FOR THIS WAS DUE TO THE STORMS
IMPACTING THE BAY BREEZE OVER THESE COUNTIES. THE BAY BREEZE IS
WHERE SLIGHTLY COOLER AIR OFF THE BAY MOVES OVER THE ADJACENT
SHORELINE COMMUNITIES AND SHIFTS THE SURFACE WIND DIRECTION ENOUGH
TO ASSIST WITH TORNADO FORMATION.

THE HARFORD COUNTY STORM PRODUCED A WEAK EF-0 TORNADO…THE
BALTIMORE COUNTY STORM PRODUCED EF-1 DAMAGE AT ITS WORST
POINT…AND THE ANNE ARUNDEL STORM DEVELOPED A WATERSPOUT JUST AS
IT MOVED OVER THE BAY.

HARFORD COUNTY…

AT 3:31 PM A TORNADO TOUCHED DOWN OVER PLEASANT HILLS/STONEYBROOK
MARYLAND. IT KNOCKED DOWN SEVERAL TREES AND LARGE BRANCHES IN THE
COMMUNITY…ONE OF WHICH FELL ON A DELIVERY TRUCK AS IT WAS MAKING
DELIVERIES. THE TORNADO PROCEEDED EAST AND WENT THROUGH SEVERAL QUICK
CYCLES OF DISSIPATION AND REGENERATION AS IT MOVED ALONG
HOLLINGSWORTH DRIVE…CAUSING SPORADIC DAMAGE. THE TORNADO MOVED
ACROSS A FARM BETWEEN HOLLINGSWORTH DRIVE AND RING FACTORY ROAD…
UPROOTING A DOZEN LARGE TREES BEFORE DISSIPATING OVER THE NORTHERN
END OF ATKISSON RESERVOIR AT 3:38 PM.

A NWS SURVEY CONCLUDED THAT THIS STORM WAS CONSISTENT WITH EF-0
DAMAGE. PEAK WINDS WERE ESTIMATED TO BE 75 MPH. THE PATH LENGTH
WAS 3 MILES WITH A WIDTH OF 100 YARDS.

BALTIMORE COUNTY…

AT 3:44 PM A TORNADO TOUCHED DOWN IN ESSEX MARYLAND. IT KNOCKED
DOWN A TREE THAT SEVERELY DAMAGED A HOME. SEVERAL OTHER TREES AND
BRANCHES WERE KNOCKED DOWN AS WELL. STREETS AFFECTED INCLUDED
WOODLYNN RD… LANCE AVE… KINWAT AVE… TIBSEN AVE… AND
HOMBURG AVE. MINOR SHINGLE AND SIDING DAMAGE WAS REPORTED THROUGH
THE COMMUNITY. DAMAGE IN THIS AREA WAS CATEGORIZED AS EF-0 DAMAGE
WITH PEAK WINDS AROUND 70 MPH.

THE STORM CONTINUED SOUTHEAST…MAINLY AS A FUNNEL CLOUD THAT DID
NOT REACH TO THE GROUND… BUT IT DID CAUSE A FEW LARGE BRANCHES
TO GET KNOCKED DOWN SPORADICALLY ALONG THE BACK RIVER NECK RD
CORRIDOR.

THE TORNADO INTENSIFIED AS IT APPROACHED BROWNS CREEK AND
BALLISTON POINT. AT 3:49 THE TORNADO WAS VIDEOTAPED NEARING
BROWNS CREEK. THE STORM MOVED ACROSS THE CREEK AND OVER BALLISTON
POINT AT 3:50 PM. THE TORNADO UPROOTED OR SNAPPED DOWN A
SIGNIFICANT PORTION OF THE LARGE TREES IN THE COMMUNITY ALONG
ISLAND VIEW ROAD…DOZENS IN ALL. THE STORM DISSIPATED AS IT MOVED
OVER THE BAY AT 3:52 PM.

RESIDENTS OF ISLAND VIEW ROAD HAD VIDEO AND PICTURES OF THE
TORNADO AND INDICATED SEEING THE TORNADO WARNING ON TELEVISION
BEFORE THE STORM STRUCK. AN NWS DAMAGE SURVEY REVEALED EF-1 DAMAGE
IN THE BALLISTON POINT AREA WITH PEAK WINDS ESTIMATED TO BE 90
MPH. TOTAL PATH LENGTH FOR THIS TORNADO WAS 5 MILES…ALTHOUGH THE
CIRCULATION SKIPPED AS IT MOVED SOUTHEAST. PATH WIDTH WAS 150
YARDS AT ITS WIDEST.

CHESAPEAKE BAY WATERSPOUT…

LASTLY…A STORM MOVING OVER NORTHERN ANNE ARUNDEL COUNTY MOVED
OUT OVER THE CHESAPEAKE BAY. A WATERSPOUT FORMED AT 3:52 PM AND
MOVED ACROSS THE BAY…PASSING JUST NORTH OF LOVE POINT ON
NORTHERN KENT ISLAND. THE WATERSPOUT DISSIPATED OVER THE CHESTER
RIVER AT 4:10 PM BEFORE IT COULD STRIKE ANY LAND. MOTORISTS ON THE
BAY BRIDGE COULD SEE THE WATERSPOUT AND SEVERAL PICTURES WERE
TAKEN. NO DAMAGE WAS REPORTED FROM THIS EVENT.
